Insects are one of the most species-rich groups on Earth. They comprise much of animal diversity and play vital roles in ecosystems, including pollination, pest control, and decomposition. However, only a fraction of this diversity has been formally described. South Africa is recognised as one of the most biologically diverse countries globally, with an estimated 44 000 insect species. Many crops rely on insect pollinators, including canola, apples, oranges, and sunflowers. A shortage of wild pollinators currently threatens crop yields, yet our knowledge of insect diversity within South Africa is sparse. There are few taxonomic specialists relative to South Africa's biodiversity, and the methods used for insect identification can be time-consuming and expensive. DNA barcoding provides an important research tool to accelerate insect biodiversity research. In this review, we queried the public DNA barcoding BOLD (Barcode of Life Data System) database for records of "Insecta" within South Africa, and 416 211 published records assigned to 28 239 unique BINs (Barcode Index Numbers) were returned. We identified five taxonomic orders with more BINs than known species in southern Africa (Hymenoptera, Diptera, Thysanoptera, Plecoptera, and Strepsiptera). Most of the barcoded records were derived from Malaise trap sampling in Gauteng, Mpumalanga and Limpopo, while the rest of South Africa remains poorly sampled. We suggest that there is a need for a comprehensive national sampling effort alongside increased investment in taxonomic expertise to generate critical baseline data on insect biodiversity before species are lost to extinction. SIGNIFICANCE: Insects provide critical ecosystem services, but our knowledge of insect biodiversity is limited. DNA barcoding can help fill biodiversity knowledge gaps; however, within South Africa, sampling has been uneven. Well-sampled provinces include Gauteng, Mpumalanga and Limpopo, while the Eastern Cape, Free State, KwaZulu-Natal, Northern Cape, North-West and Western Cape remain under-sampled. We argue for a broad national Malaise trapping effort to generate crucial baseline data on insect biodiversity. Without urgent investment in taxonomic expertise and biomonitoring, we risk losing much of our biodiversity before it is even described.

RESUMEN En proyectos hidroeléctricos se han realizado pocas investigaciones para determinar la composición taxonómica de dípteros de la familia Psychodidae, subfamilia Phlebotominae. En este trabajo se realizó un inventario taxonómico de flebótomos en el área de influencia de la central hidroeléctrica de Ituango, departamento de Antioquia con el fin de actualizar su distribución y resaltar su importancia médica como vectores del protozoo del género Leishmania. Para esto, se realizaron monitoreos entomológicos con trampas CDC y trampas Shannon, en diez municipios de la subregión occidente (Santa Fe de Antioquia, Peque, Olaya, Liborina y Sabanalarga) y de la subregión norte (municipios de Ituango, Briceño, Valdivia, Toledo y San Andrés de Cuerquia). Para la identificación taxonómica se utilizaron las claves de Young y Duncan y Galati. En total se recolectaron 7993 flebótomos, distribuidos en 39 especies según Galati, destacándose seis especies consideradas vectores de especies de Leishmania, que causan la leishmaniasis cutánea. Estas especies fueron Lutzomyia (Trl.) gomezi, Lu. (Hel.) hartmanni, Psychodopygus panamensis, Pintomyia (Pif.) columbiana, Nyssomyia trapidoi y Ny. yuilli yuilli. Los datos indican que la zona de muestreo es endémica para la leishmaniasis debido a la presencia de vectores transmisores de este parásito. El inventario sobre la distribución de flebótomos servirá de base para estudios posteriores que permitan la implementación de estrategias de vigilancia y control.

ABSTRACT In hydroelectric projects, few investigations have been carried out to determine the taxonomic composition of diptera of the family Psychodidae, subfamily Phlebotominae. In this work, a taxonomic inventory of phlebotomine sandflies was conducted in the area of influence of the Ituango hydroelectric power plant, in the department of Antioquia, Colombia. We highlight their medical importance as vectors of the protozoan of the genus Leishmania and update their distribution. Entomological monitoring was carried out in ten municipalities from the western subregion (Santa Fe de Antioquia, Peque, Olaya, Liborina and Sabanalarga) and the northern subregion (the municipalities of Ituango, Briceño, Valdivia, Toledo and San Andrés de Cuerquia). CDC traps and Shannon traps were used for monitoring. For taxonomic identification, the keys of Young and Duncan and Galati were used. A total of 7993 phlebotomine sandflies were collected, distributed in 39 species according to Galati, highlighting six species considered vectors of Leishmania spp. that causes cutaneous leishmaniasis, which are: Lutzomyia (Trl.) gomezi, Lu. (Hel.) hartmanni, Psychodopygus panamensis, Pintomyia (Pif.) columbiana, Nyssomyia trapidoi and Ny. yuilli yuilli. We conclude that the sampling area is endemic for leishmaniasis due to the presence of vectors transmitting this parasite. The inventory on the distribution of phlebotomine sandflies will serve as a basis for further studies that allow the implementation of surveillance and control strategies.

Abstract The presence of Eristalis tenax in a dairy farm in the province of Salta is described. Larvae of E. tenax, known as "rat-tailed maggots", were found in large quantities on the premises, specifically in the feeding trough and waste pit. Taxonomic identification revealed distinctive morphological characteristics of the species. This finding expands the known geographical distribution of E. tenax in Argentina. Although the medical significance of these syrphids is relative, their ability to act as mechanical vectors of certain pathogens, such as mycobacteria, suggests the need to control their populations in anthropized environments. The importance of hygiene measures to prevent accidental ingestion of larvae is stressed, and monitoring of water tanks and pits is suggested. In conclusion, the relevance of recognizing the facultative nature of infestations is highlighted, along with the potential contribution of E. tenax control in sanitation measures of affected herds.

Resumen Este trabajo documenta la presencia de Eristalis tenax en un establecimiento lechero de la provincia de Salta. Las larvas de E. tenax, conocidas como "gusanos de cola de rata", se encontraron específicamente en el comedero y la fosa de desechos. La observación de las características morfológicas de la especie permitió su identificación taxonómica. Este hallazgo amplía la distribución geográfica conocida de E. tenax en Argentina. Aunque la importancia médica de estos sírfidos es relativa, se destaca su capacidad de actuar como vectores mecánicos de micobacterias, lo que sugiere la necesidad de controlar sus poblaciones en entornos antropizados. Se enfatiza la importancia de medidas de higiene para prevenir la ingestión accidental de larvas y se sugiere incorporar supervisión en depósitos de agua y piletones de decantación. En conclusión, se subraya la relevancia de reconocer la naturaleza facultativa de esta especie como posible vector y la contribución de su control en las medidas de saneamiento en rodeos afectados.

Resumen La entomotoxicología forense, que analiza insectos necrófagos para detectar sustancias tóxicas, es crucial en la determinación de causas de muerte y la estimación del intervalo post-mortem. Este estudio se centró en Peckia intermutans (Walker) (Diptera: Sarcophagidae) como marcador para la detección de metanol, un alcohol potencialmente letal presente como adulterante en bebidas alcohólicas debido a su bajo costo y parecido con el etanol. Se desarrolló un método de cromatografía de gases-espectrometría de masas (HS-GC-MS) para detectar metanol y se estudió su efecto sobre el tiempo de desarrollo, supervivencia y morfología de las moscas de la carne. Las larvas se criaron en sustratos de hígado enriquecidos con metanol (300, 500 y 1000 mg/kg). Los resultados mostraron: el método desarrollado detectó metanol en todos los estadios; el metanol afectó el tiempo de desarrollo de las moscas; la supervivencia aumentó con una mayor concentración de metanol; y los cambios morfológicos fueron evidentes en el peso. Este estudio ofrece valiosa información sobre la investigación entomotoxicológica del Ecuador, por lo que se debe considerar los cambios morfológicos de P. intermutans para evitar estimaciones inexactas de los intervalos post-mortem.

Abstract Forensic entomotoxicology, which analyzes necrophagous insects to detect toxic substances, is crucial in determining causes of death and estimating the post-mortem interval. This study focused on Peckia intermutans (Walker) (Diptera: Sarcophagidae) as a marker for detecting methanol, a potentially lethal alcohol often added as an adulterant in alcoholic beverages due to its low cost and similarity to ethanol. A gas chromatography-mass spectrometry (HS-GC-MS) method was developed to detect methanol, and its effects on the development time, survival, and morphology of flesh flies were investigated. Larvae were reared on liver substrates enriched with methanol (300, 500, and 1000 mg/kg). Results showed: the developed method detected methanol in all instars; methanol affected the developmental time of the flies; survival increased with higher methanol concentration; and morphological changes were evident in weight. This study provides valuable information on entomotoxicological research in Ecuador, emphasizing the need to consider morphological changes in P. intermutans to avoid inaccurate estimations of post-mortem intervals.

Abstract To determine the species composition, relative abundance and seasonal variation of different mosquitoes Genera (Aedes, Anopheles, Armigeres, Culex, and Culiseta) in different habitats the present research work was carried out in Entomology Research Laboratory of The University of Peshawar. Sampling performed from variety of permanent and temporary breeding habitats was carried out on monthly basis from targeted breeding sites for two consecutive years through dipping method. Species diversity in the survey sites was noted. Collection from these seventeen various types of potential larval habitats, yielded a total of 42,430 immature constituting 41,556 larvae and 874 pupae. Among these only 19,651 adult mosquitoes emerged comprising 11,512 female and 8,139 male mosquitoes. 78% (n= 15333) of mosquito larvae were from permanent and 22% (n=4318) were from temporary breeding sites. This study showed that Peshawar valley harbours 15 species from the genera Aedes, Anopheles, Armigeres, Culex and Culiseta. When the density of each species was examined, Culex quinquifasciatus was found to be dominant (79%) and constant in distribution. Among the temporary habitats Aedes albopictus was found as the most prevalent species particularly from tree holes and water cisterns. The highest intensity of mosquitoes was in June (2243 emerged adults) and November (2667 emerged adults) while the lowest was in January (203 emerged adults). A perfect positive correlation (r = +0.8) was found between temperature and population of mosquitoes (df 10 and α 0.05). The species diversity index for mosquitoes remained between 0.12 and 1.76. The Margalef’s richness components was noticeably low for bamboo traps (0.2) and fairly high for rice fields, Percolating water and Animal tracks (1.3) which shows the abundance of mosquito species in these habitats. Similarly Pielou’s Evenness was highest for bamboo traps (E=1) showing species uniform distribution. Animal tracks were presumed not only the diverse habitat rather also possessed high value for species richness and species evenness. Temperature, rainfall, humidity and other related attributes responsible for species variation and abundance need to be analysed further to pave way for controlling vector species in their oviposition targeted sites. composition (Aedes Anopheles Armigeres Culiseta method noted 42430 42 430 42,43 41556 41 556 41,55 87 pupae 19651 19 651 19,65 11512 11 512 11,51 8139 8 139 8,13 78 n= n (n 15333 22 n=4318 n4318 4318 (n=4318 1 examined 79% 79 (79% distribution cisterns 2243 (224 adults 2667 (266 203 (20 adults. . r +0.8 08 0 df 0.05. 005 0.05 05 0.05) 012 12 0.1 176 76 1.76 Margalefs Margalef s 0.2 02 2 (0.2 fields 1.3 13 3 (1.3 Pielous Pielou E=1 E1 E (E=1 evenness Temperature rainfall 4243 4 43 42,4 4155 55 41,5 1965 65 19,6 1151 51 11,5 813 8,1 7 1533 n=431 n431 431 (n=431 (79 224 (22 266 (26 20 (2 +0. 00 0.0 01 0. 17 1.7 (0. 1.

Resumo Para determinar a composição de espécies, abundância relativa e variação sazonal de diferentes gêneros de mosquitos (Aedes, Anopheles, Armigeres, Culex e Culiseta) em diferentes habitats, o presente trabalho foi realizado no Laboratório de Pesquisa em Entomologia da Universidade de Peshawar. A amostragem coletada a partir de uma variedade de habitats de reprodução permanentes e temporários foi realizada mensalmente a partir de locais de reprodução alvo por 2 anos consecutivos através do método de imersão. A diversidade de espécies nos locais de pesquisa foi anotada. A coleta desses 17 tipos diferentes de habitats larvais potenciais rendeu um total de 42.430 imaturos, constituindo 41.556 larvas e 874 pupas. Destes, emergiram apenas 19.651 mosquitos adultos, sendo 11.512 fêmeas e 8.139 machos. 78% (n = 15333) das larvas do mosquito eram de criadouros permanentes e 22% (n = 4318) de criadouros temporários. Este estudo mostrou que o vale de Peshawar abriga 15 espécies dos gêneros Aedes, Anopheles, Armigeres, Culex e Culiseta. Quando a densidade de cada espécie foi examinada, Culex quinquifasciatus foi considerado dominante (79%) e constante na distribuição. Entre os habitats temporários, o Aedes albopictus foi encontrado como a espécie mais prevalente, principalmente em ocos de árvores e cisternas de água. A maior intensidade de mosquitos foi em junho (2.243 adultos emergidos) e novembro (2.667 adultos emergidos), enquanto a menor foi em janeiro (203 adultos emergidos). Uma correlação positiva perfeita (r = +0,8) foi encontrada entre temperatura e população de mosquitos (DF 10 e α 0,05). O índice de diversidade de espécies de mosquitos permaneceu entre 0,12 e 1,76. Os componentes de riqueza de Margalef foram visivelmente baixos para armadilhas de bambu (0,2) e razoavelmente altos para campos de arroz, água percolada e rastros de animais (1,3), o que mostra a abundância de espécies de mosquitos nesses habitats. Da mesma forma, a uniformidade de Pielou foi maior para armadilhas de bambu (E = 1), mostrando distribuição uniforme das espécies. As pegadas de animais foram presumidas não apenas como habitat diverso, mas também possuíam alto valor para riqueza e uniformidade de espécies. Temperatura, chuva, umidade e outros atributos relacionados responsáveis pela variação e abundância das espécies precisam ser analisados mais a fundo para abrir caminho para o controle de espécies de vetores em seus locais de oviposição alvo.

ABSTRACT The emergence of insecticide resistance in different mosquito populations underscores the pressing need for alternative approaches to control vector-borne diseases. Among several technological strategies, the employment of bacterial symbionts, such as the Wolbachia pipientis strains wMel and wAlbB to inhibit the ability of Aedes aegypti (Linnaeus, 1762) to transmit dengue and Zika viruses in endemic regions worldwide is promising. This investigation examines both the bacterial diversity associated with Culex quinquefasciatus and the genetic diversity of Wolbachia in females collected in Coari, Amazonas State, Brazil. Both 16S rRNA and Wolbachia surface protein (wsp) gene sequences were generated and examined. Proteobacteria was the dominant phylum. Wolbachia was the predominant genus, followed by Providencia, unclassified Erwiniaceae, and Acinetobacter. The presence of Delftia in Cx. quinquefasciatus need further investigations to identify the strains and if any of them can inhibit the transmission of arboviruses by this mosquito. Wolbachia 16S rRNA sequences were detected in all samples analyzed. The wsp sequences from Coari specimens were identified as Wolbachia wPip strain of the supergroup B. These sequences are identical and share 100% similarity with those of other Cx. quinquefasciatus populations from Brazil. Our findings suggest the hypothesis of previous studies that the Wolbachia invasion in Cx. quinquefasciatus was recent. vectorborne vector borne diseases strategies symbionts Linnaeus, Linnaeus (Linnaeus 1762 promising State Brazil S (wsp examined phylum genus Providencia Erwiniaceae Acinetobacter Cx analyzed B 100 recent 176 10 17 1

ABSTRACT Brazil has been suffering a dengue (DENV) epidemic in 2019 and 2022 and records cases of Zika (ZIKV) and chikungunya (CHIKV). Londrina city, Paraná, stands out for the number of cases and deaths from dengue. Therefore, this study aimed to verify the density and diversity of mosquitoes present in urban public establishments of Londrina, to analyze their ecological relationships, and to investigate the presence of the DENV, ZIKV, and CHIKV. Ovitraps were installed in outdoor sites in two public establishments in each region of Londrina, while adult culicids were caught indoors with a Nasci aspirator. A total of 5077 eggs were obtained in 77 ovitraps. The South region had the highest infestation while the East had the lowest (Ovitrap Positivity Index: 38% and 25%; Egg Density Index: 67.83 and 19.03, respectively). From eggs, 704 Aedes aegypti females and 71 Aedes albopictus females were obtained, while in the aspiration of adults, 99 A. aegypti and 11 Culex quinquefasciatus were captured, the highest number in the West and the lowest in the North. The DENV-II virus was detected in a pool of 17 A. aegypti females in the West region. The results demonstrate high density of pathogen vector species, mainly A. aegypti, in and around establishments, alerting to the need for constant local entomological surveillance to prevent viral circulation, mainly in crowded places. The presence of A. albopictus around the establishments also alerts to the urbanization of the species and potential participation in the viral circulation, demonstrating the need for constant monitoring.

Abstract Species of the genus Anastrepha cause injuries to several fruits and vegetables in the Nearctic and Neotropical regions. Among these species, many are present in Brazil. In this study, we surveyed the existing Anastrepha species in the Brazilian Chaco Biome. We evaluated possible influences of climate and vegetation on the occurrence of Anastrepha spp. For this, we used traps and hydrolyzed protein as bait. Collections were carried out in three distinct floristic compositions in the Chaco biome, from permanently dry areas to flooded sites. We identified Anastrepha fraterculus (Wiedemann, 1830), A. sororcula Zucchi 1979, A. undosa Stone 1942, and A. daciformis Bezzi 1909. The dry and flooded environment did not influence the occurrence of Anastrepha species. The presence of multiple hosts increases the number of species. The richness and abundance of Anastrepha species are lower in the Brazilian Chaco than in other native environments. regions Brazil study Biome spp bait biome sites Wiedemann, Wiedemann (Wiedemann 1830, 1830 , 1830) A 1979 1942 1909 environments 183 197 194 190 18 19 1

ABSTRACT Mansonia Blanchard mosquitoes are aggressive and opportunistic, making it difficult for habitation in certain areas. However, there is no data regarding their rearing in laboratory in Brazil. Therefore, the aim of this study was to evaluate the effect of different diet composition on the development of Mansonia humeralis immatures. The plant Pistia stratiotes was used as a substrate for larval attachment, and fish food (Tetra Marine® Flakes) and baker's yeast (Saccharomyces cerevisiae) in various combinations were used as feed. Eggs and larvae were obtained from mosquitoes collected in the field using protected human catches, and the experiments were conducted in the laboratory (25-27°C and 70-80% relative humidity) with 200 larvae per container (n=15). Mortality rate, larval development time, pupation rate, emergence rate, and the number of eggs and larvae were recorded. Overall, a high mortality rate (0.5 – 0.7) was observed in the first 12 days of the experiment in all diets, up to 50% of adults emerged from the remaining larvae with a male to female ratio of 1.1 to 1.3. The use of yeast in combination with fish food resulted in lower mortality rate (0.52), a shorter larval development time (34 days), a higher pupation rate (0.21) and number of eggs (21 eggs) compared to the other diets. However, fertility was very low (1%) regardless of the diet used. The use of yeast is recommended as part of the diet offered to this mosquito species under the laboratory conditions used in our study. opportunistic areas However Brazil Therefore immatures attachment Tetra Marine Flakes bakers baker s Saccharomyces cerevisiae feed catches 2527°C 2527C C 25 27°C 27 7080% 7080 70 80% 80 70-80 humidity 20 n=15. n15 n n=15 . 15 (n=15) recorded Overall 0.5 05 0 5 (0. 0.7 07 7 1 diets 50 11 1. 13 3 1.3 0.52, 052 0.52 , 52 (0.52) 34 (3 days, days) 0.21 021 21 (0.21 (2 1% (1% 2527 2 27C 708 8 70-8 n1 n=1 (n=15 0.

ABSTRACT Background: The riverine communities of the Amazon comprise different social groups that inhabit the rural areas on the banks of rivers and lakes. Residents usually travel by river to rural and urban areas and are then exposed to urbanized diseases such as those caused by arbovirus infection. In Brazil, emerging diseases such as dengue, Zika, chikungunya, and those caused by infection with Oropouche and Mayaro viruses necessitate epidemiological surveillance. This study was aimed at determining the frequency of positivity for immunoglobulin (Ig)G and IgM antibodies against Zika, chikungunya, and dengue viruses and performing molecular analyses to detect viral RNA for the Zika, chikungunya, dengue virus, Oropouche, and Mayaro viruses, in the same serum samples obtained from riverside populations. Methods: This cross-sectional study was conducted in a riverside population in the Humaitá municipality of the Brazilian Amazon. More than 80% of the local population participated in this study. Entomological samples were collected to identify local mosquito vectors. Results: Analysis of 205 human serological samples revealed IgG antibodies against the dengue virus in 85 individuals. No molecular positivity was observed in human samples. Entomological analyses revealed 3,187 Diptera species, with Mansonia being the most frequent genus. Aedes aegypti and Aedes albopictus were not detected in the two collections. Conclusions: IgG antibodies against the dengue virus were highly prevalent, suggesting previous exposure. The absence of the arbovirus vectors Aedes aegypti and Aedes albopictus in the samples supports the hypothesis that the infections recorded likely occurred outside the riverside communities investigated.

Abstract Oestrus ovis larvae are obligate parasites of vertebrates and cause cavitary myiasis (oestrosis) in sheep and goats. It is also reported as a zoonosis causing ophthalmomyiasis and nasopharyngeal myiasis. Despite being relatively common in Brazil, epidemiological studies on O. ovis are scarce. Considering that the infestation is influenced by the climate and biomes of the studied region, we aimed to investigate the seasonal prevalence of O. ovis among slaughtered sheep in the northern region of the state of Mato Grosso, Brazil. The heads of sheep (n=697) slaughtered at a slaughterhouse in the municipality of Terra Nova do Norte (November 2011 to November 2013) were collected to count, catalog, and identify the larvae found in the upper respiratory tract. Overall, 45.77% (319/697) of the animals were infested with 2,412 recovered larvae, 96.89% (2,337/2,412) of which were identified at the species level as O. ovis. Seasonal variations in prevalence ranged from 41% (spring) to 56% (summer); however, no correlation was observed between prevalence and season, mean humidity, or temperature. In conclusion, parasitism by O. ovis in sheep in the studied area, occurs year-round, considering the occurrence of larvae (L1, L2, and L3) throughout the year, probably because of the area's environmental conditions. oestrosis (oestrosis goats Brazil O scarce Grosso n=697 n697 n 697 (n=697 201 2013 count catalog tract Overall 4577 45 77 45.77 319/697 319697 319 (319/697 2412 2 412 2,41 9689 96 89 96.89 2,337/2,412 23372412 337 (2,337/2,412 41 spring (spring 56 summer (summer) however season humidity temperature conclusion area yearround, yearround year round, round year-round L1, L1 L (L1 L2 L3 areas s conditions n=69 n69 69 (n=69 20 457 4 7 45.7 319/69 31969 31 (319/69 241 2,4 968 9 8 96.8 2,337/2,41 2337241 33 (2,337/2,41 5 (summer (L n=6 n6 6 (n=6 45. 319/6 3196 3 (319/6 24 2, 96. 2,337/2,4 233724 (2,337/2,4 n= (n= 319/ (319/ 2,337/2, 23372 (2,337/2, (n (319 2,337/2 2337 (2,337/2 (31 2,337/ 233 (2,337/ (3 2,337 23 (2,337 ( 2,33 (2,33 2,3 (2,3 (2, (2

Resumo As larvas de Oestrus ovis são parasitas obrigatórios de vertebrados e causam miíase cavitária (estrose) em ovinos e caprinos. Também é relatada como uma zoonose que causa oftalmomíase e miíase nasofaríngea. Apesar de relativamente comum no Brasil, os estudos epidemiológicos sobre O. ovis são escassos. Considerando que a infestação é influenciada pelo clima e biomas da região estudada, objetivou-se investigar a prevalência sazonal de O. ovis entre ovinos abatidos na região norte do estado de Mato Grosso, Brasil. Foram coletadas cabeças de ovinos (n=697) abatidos em frigorífico do município de Terra Nova do Norte (novembro de 2011 a novembro de 2013) para contagem, catalogação e identificação das larvas encontradas no trato respiratório superior. No geral, 45,77% (319/697) dos animais estavam infestados com 2.412 larvas recuperadas, das quais 96,89% (2.337/2.412) foram identificadas em nível de espécie como O. ovis. As variações sazonais na prevalência variaram de 41% (primavera) a 56% (verão); no entanto, não foi observada correlação entre prevalência e estação do ano, umidade média ou temperatura. Conclui-se que o parasitismo por O. ovis em ovinos na área estudada ocorre durante todo o ano, considerando a ocorrência de larvas (L1, L2 e L3) ao longo do ano, provavelmente devido às condições ambientais da área. estrose (estrose caprinos nasofaríngea Brasil O escassos objetivouse objetivou se Grosso n=697 n697 n 697 (n=697 201 2013 contagem superior geral 4577 45 77 45,77 319/697 319697 319 (319/697 2412 2 412 2.41 recuperadas 9689 96 89 96,89 2.337/2.412 23372412 337 (2.337/2.412 41 primavera (primavera 56 verão (verão) entanto ano temperatura Concluise Conclui L1, L1 L (L1 L3 n=69 n69 69 (n=69 20 457 4 7 45,7 319/69 31969 31 (319/69 241 2.4 968 9 8 96,8 2.337/2.41 2337241 33 (2.337/2.41 5 (verão (L n=6 n6 6 (n=6 45, 319/6 3196 3 (319/6 24 2. 96, 2.337/2.4 233724 (2.337/2.4 n= (n= 319/ (319/ 2.337/2. 23372 (2.337/2.

Abstract: The Annonaceae family besides its commercial value ( Annona cherimola, , A. macroprophyllata, A. muricata, A. reticulata, A. purpurea , A. squamosa, Annona x atemoya) also produces several active secondary metabolites. Among these metabolites, Annonaceous acetogenins which are exclusive in this family, are reported with insecticidal activity on various species of insects that are crop pests and disease vectors. This review systematizes what is reported in the scientific literature about them: aspects such as the plant species from which the acetogenins come, and the insecticidal potential using the comparative activity index; it also takes into account lethality, morphological, physiological, and behavioral changes, including deterrent and anti-feeding effects. Eighty-five annonaceous acetogenins are documented on thirty species of insects, as well as toxic activities at various stages of development, broad-spectrum, and differential. The studies on Aedes aegypti (Diptera) and Spodoptera frugiperda (Lepidoptera) and the activity of squamocin on fifteen species of insects stand out. Annonaceous acetogenins are toxic at low concentrations, considering evaluation standards and comparison with commercial insecticides, and are active at various stages of insect development. The low proportion of studied species of the Annonaceae means the opportunity to find molecules with this biological potential, and an argument for its conservation.

Resumo: A família Annonaceae possui espécies frutícolas que, além do valor comercial ( Annona cherimola, A. macroprophyllata, A. muricata, A. reticulata, A. purpurea, A. squamosa e Annona x atemoya), produzem diversos metabólitos especializados muito ativos. Dentre estes, relata-se o grupo das acetogeninas, que são moléculas específicas da família e que apresentam atividade inseticida em várias espécies de insetos, que são pragas de culturas e vetores de doenças. Esta revisão sistematiza o que é relatado na literatura científica sobre acetogeninas: tais como acedas espécies vegetais de onde provêm e seu potencial inseticida referido peloíndice comparativo de atividade; também leva em consideração a letalidade, as alteraçõesmorfológicas,fisiológicas e comportamentais, incluindo efeitos dissuasores eantialimentares. Oitenta e cinco acetogeninas anonáceas estão documentadas com atividades sobre trinta espécies de insetos, com atividades tóxicas em vários estágios de desenvolvimento, comamplo espectro de ação e de modo diferencial. Destacam-se os estudos sobre Aedes aegypti(Diptera) e Spodoptera frugiperda (Lepidoptera) e a atividade da acetogenina squamocinasobre quinze espécies de insetos. Acetogeninas anonáceas são tóxicas em baixasconcentrações, considerando padrões de avaliação e comparação com inseticidas comerciais, e são ativas em vários estágios de desenvolvimento do inseto. A baixa proporção de espécies estudadasda família Annonaceae significa a oportunidade de encontrar muito mais moléculas com essepotencial biológico, e um argumento para sua conservação.
