RESUMO Os crisopídeos (Chrysopidae) são predadores que regulam as populações de cochonilhas, pulgões, moscas brancas e lepidópteros em diversas culturas de importância agrícola. O predador Chrysoperla genanigra Freitas (Neuroptera: Chrysopidae) é amplamente encontrado em áreas de produção de melão, onde diversos agrotóxicos são normalmente aplicados para o controle de pragas. Estudos que avaliam o impacto desses pesticidas sobre C. genanigra são incipientes. Assim, o objetivo deste estudo foi avaliar a toxicidade residual de sete inseticidas sobre larvas de C. genanigra. O experimento foi conduzido em condições de laboratório com temperatura de 25±2 °C, umidade relativa de 70±10% e fotoperíodo de 12 horas. Os tratamentos testados foram: azadiractina, abamectina, ciantraniliprole, tiacloprido, pimetrozina, imidacloprido, novaluron e água destilada (controle). Os inseticidas foram aplicados nas maiores dosagens recomendadas pelos fabricantes, e suas toxicidades foram categorizadas usando o método recomendado pela Organização Internacional de Controle Biológico (IOBC). Todos os inseticidas afetaram significativamente a mortalidade larval, a porcentagem de pupação e a emergência de adultos do predador C. genanigra. A mortalidade total acumulada variou de 93% a 100% entre os inseticidas analisados; a maior taxa de mortalidade foi encontrada para larvas de primeiro instar. Os sete inseticidas foram classificados toxicologicamente como Classe 4 e, portanto, não seletivos para o predador quando testados em larvas de primeiro instar de C. genanigra. Pesquisas em condições de campo e semicampo devem ser realizadas para avaliar a seletividade dos inseticidas testados.

ABSTRACT Lacewings (Chrysopidae) are predators that regulate mealybug, aphid, whitefly, and lepidopteran populations in various important agricultural crops. The predator Chrysoperla genanigra Freitas (Neuroptera: Chrysopidae) is widely found in melon production areas, where various chemical pesticides are usually applied for pest control. Studies evaluating the impact of these pesticides on C. genanigra are incipient. Thus, the objective of this study was to assess the residual toxicity of seven insecticides on C. genanigra larvae. The experiment was conducted under laboratory conditions at temperature of 25±2 °C, relative humidity of 70±10%, and 12-hour photoperiod. The treatments tested were: azadirachtin, abamectin, cyantraniliprole, thiacloprid, pymetrozine, imidacloprid, novaluron, and distilled water (control). Insecticides were applied at the highest rates recommended by the manufacturers, and their toxicities were categorized using the method recommended by the International Organization for Biological Control (IOBC). All insecticides significantly affected larval mortality, pupation percentage, and adult emergence of the predator C. genanigra. Total accumulated mortality ranged from 93% to 100% among the analyzed insecticides; the highest mortality rate was found for firstinstar larvae. The seven insecticides were toxicologically classified as Class 4 and, therefore, non-selective to the predator when tested on first-instar larvae of C. genanigra. Research under semi-field and field conditions should be conducted to assess the selectivity of the tested insecticides.

ABSTRACT Herein, we describe Ecualeon peruvianus sp. nov. from Peru, a new species of Ecualeon Stange, a genus that was previously monotypic, and only known from Ecuador. Meanwhile, we discuss the characters of this genus, highlighting that some characters previously known solely from the type species are now considered generic features.

Abstract Between October 2009 and December 2011, five Malaise traps/area were used to survey of the lance lacewings (Neuroptera: Osmylidae) in five areas of the Atlantic rainforest in São Paulo state, Brazil. Were obtained 73 specimens of Isostenosmylus pulverulentus (Gerstaecker, 1894) (96.1% of the total collected), two of Gumilla adspersus Navás, 1912 (2.6%), and one of Isostenosmylus sp. (1.3%). The osmylids were more frequently observed in the Parque Estadual da Serra do Mar / Núcleo Santa Virgínia (59.2% of the total collected), Parque Estadual Intervales (30.3%) and Parque Estadual Morro do Diabo (7.9%), inland collection sites in the state of São Paulo, Brazil. The geographic range of G. adspersus is expanded to include the states of São Paulo and Rio de Janeiro, Brazil, based on two studied specimens and one record in the citizen science website iNaturalist.

Abstract Climaciella Enderlein is a genus of the family Mantispidae (Neuroptera) restricted to the New World with records ranging from southern Canada to northern Argentina. The genus is currently represented by 12 valid species, three of them with records from Brazil: C. amapaensis Penny, C. duckei Navás, and C. semihyalina (Le Peletier & Audinet-Serville). Besides the relatively low number of species from Brazil, it is known that Climaciella species present some historical taxonomic problems. In this sense, the main goal of this study was to taxonomically revise the Climaciella species from Brazil, providing detailed (re)descriptions and illustrations of all species, an updated distribution map, and an identification key to the whole genus. The study resulted in some new taxonomic acts: C. tincta (Navás) is revalidated and C. duckei is considered a new synonym of C. tincta; two new species are described: Climaciella hoffmani sp. nov. and Climaciella pennyi sp. nov.

Resumo Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) é amplamente distribuído por todo o ecossistema de cerrado. Os frutos de C. brasiliense são utilizados na alimentação humana e constitui uma importante fonte de renda para muitas comunidades. A perda de habitat provocada pelas mudanças de uso da terra coloca em risco a conservação de C. brasiliense. Insetos sugadores constituem um importante fator ecológico que, potencialmente, afeta o fitness de C. brasiliense em ambientes degradados. Além disso, as metodologias de amostragem de insetos para aplicação em estudos relacionados à conservação de C. brasiliense são pouco desenvolvidas. Neste estudo, o número de insetos sugadores (Hemiptera) e seus predadores foram avaliados em três estratos verticais do dossel de C. brasiliense. A distribuição das espécies sugadoras apresentou estratificação vertical ao longo da estrutura do dossel. O estrato basal do dossel apresentou o maior número de insetos sugadores Aphis gossypii (Glover 1877) (Hemiptera: Aphididae) e Bemisia tabaci (Genn. 1889) (Hemiptera: Aleyrodidae), e seus predadores Chrysoperla sp. (Neuroptera: Chrysopidae), aranhas (Araneae) e Zelus armillatus (Lep. & Servi., 1825) (Hemiptera: Reduviidae). Os predadores distribuíram-se de acordo com a disponibilidade de recursos, ocorrendo em maior número nas partes do dossel com maior abundância de suas presas.

Abstract Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) trees are widely distributed throughout the Cerrado ecosystem. The fruits of C. brasiliense trees are used by humans for food and as the main income source in many communities. C. brasiliense conservation is seriously threatened due to habitat loss caused by the land-use change. Sucking insects constitute an important ecological driver that potentially impact C. brasiliense survival in degraded environments. In addition, insects sampling methodologies for application in studies related to the conservation of C. brasiliense are poorly developed. In this study, sucking insects (Hemiptera) and their predators were recorded in three vertical strata of Caryocar brasiliense canopies. The distribution of sucking species showed vertical stratification along the canopy structure of C. brasiliense. The basal part of the canopy had the highest numbers of sucking insects Aphis gossypii (Glover 1877) (Hemiptera: Aphididae) and Bemisia tabaci (Genn. 1889) (Hemiptera: Aleyrodidae), and their predators Chrysoperla sp. (Neuroptera: Chrysopidae), spiders (Araneae), and Zelus armillatus (Lep. & Servi., 1825) (Hemiptera: Reduviidae). Predators' distribution follows the resource availability and preferred C. brasiliense tree parts with a higher abundance of prey.

ABSTRACT Duponchelia fovealis is an important pest in strawberry crops. In search of an alternative biological control method, the objective of this study was to assess the effects of a diet composed of Ephestia kuehniella or D. fovealis eggs offered to Chrysoperla externa larvae on their subsequent development and survival under controlled conditions. Biological and reproductive parameters of C. externa were assessed. Additionally, the daily predation of D. fovealis eggs by C. externa was analyzed. Finally, a fertility life table was constructed. The egg-to-pupa development time differed significantly between diets. The weights of firstand second-generation male C. externa pupae were significantly higher when fed on D. fovealis eggs. Males tended to live longer on a diet based on D. fovealis eggs, but females presented no significant differences between diets. The oviposition period tended to be longer for C. externa fed on D. fovealis eggs. The time between generations and the net reproductive rate were greater for C. externa fed on D. fovealis eggs. The results showed that D. fovealis eggs are a suitable diet for the development of C. externa. This information is important for developing protocols for the use of C. externa as a biocontrol agent against this pest.

RESUMO Duponchelia fovealis é uma praga severa no cultivo do morangueiro. Na busca de uma alternativa de agente de controle biológico, avaliamos o impacto de uma dieta composta por ovos de Ephestia kuehniella ou D. fovealis oferecidas às larvas de Chrysoperla externa em seu subsequente desenvolvimento e sobrevivência, sob condições controladas. Foram avaliados os parâmetros biológicos e reprodutivos de C. externa e a predação diária de ovos de D. fovealis por C. externa. Por fim, foi construída a tabela de vida de fertilidade. A duração do período do ovo à pupa diferiu significativamente entre as dietas. O peso das pupas de C. externa foi significativamente maior quando alimentadas com ovos de D. fovealis para machos de primeira e segunda geração. Os machos tenderam a viver mais tempo com uma dieta baseada em ovos de D. fovealis, mas não foram detectadas diferenças significativas entre as dietas para as fêmeas. O período de oviposição tendeu a ser mais longo em C. externa alimentada com ovos de D. fovealis. A predação média diária da primeira geração de C. externa foi afetada pela dieta. O tempo entre cada geração e a taxa líquida de reprodução foram maiores para C. externa alimentada com ovos de D. fovealis do que quando alimentada com ovos de E. kuehniella. Nossos resultados comprovaram que os ovos de D. fovealis são uma dieta adequada para o desenvolvimento de C. externa. Esta informação é valiosa no desenvolvimento de protocolos para o uso de C. externa como agente de controle desta praga.

Abstract Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) is a predator used in biological pest control, so establishing laboratory breeding methods is essential for the use of these organisms in the field. The objective of this work was to obtain the biological and population parameters of this species under laboratory conditions. The experiment was carried out in the Laboratory of Biological Control of the College of Postgraduates, Puebla Campus in 2021; with a population collected in the vegetable-growing area in Los Reyes de Juárez, Puebla. Following a standardized breeding protocol and after the population was adapted to the laboratory conditions, bioassays were performed to obtain the population parameters, individualizing 50 eggs in Petri dishes, and observing the development until the adult stage. Three couples of adults were formed and followed until death. The preoviposition period was 4.6 days, average longevity of 53 days, on average a female laid a total of 1 289 eggs, 25.56 eggs per day, and a hatching of 88.35%. The average development from egg to adult was 24.19 days with cumulative survival of 32% and a sex ratio of 0.6, the rm value was 0.18014. The knowledge generated in this work has been very useful to program the breeding of this insect, obtain egg production on certain dates, and for people who would like to engage in the breeding of this predator.

Resumo O objetivo foi avaliar a ação residual dos inseticidas acetamipride + etofenproxi, espinetoram, indoxacarbe e metoxifenozida sobre o predador Chrysoperla externa Hagen, 1861 (Neuroptera: Chrysopidae). Os bioensaios seguiram as metodologias propostas pela International Organization for Biological and Integrated Control (IOBC). Os inseticidas foram pulverizados em plantas de videira cv. Borgonha, usando a dosagem máxima de campo recomendada para frutíferas. Larvas e adultos do predador foram expostos às folhas contendo os resíduos do inseticida, aos 3, 10, 17, 24 e 31 dias após a pulverização, para determinar o efeito residual sobre os seguintes parâmetros biológicos: mortalidade, fecundidade e fertilidade. Com base na toxicidade observada durante os bioensaios, os inseticidas foram classificados de acordo com a classificação de persistência da IOBC. Espinetoram foi classificado como moderadamente persistente para larvas e levemente persistente para adultos, indoxacarbe também foi considerado moderadamente persistente para larvas e, como de vida curta para a fase adulta do crisopídeo, mostrando assim a diferença de suscetibilidade entre os estágios de desenvolvimento de C. externa. Os inseticidas acetamiprido + etofenproxi e metoxifenozida são os mais indicados para aplicação ecologicamente segura, em áreas onde o predador ocorre naturalmente, pois são classificados como inseticidas de vida curta (classe 1) para os estágios larval e adulto de C. externa. espinetoram Hagen 186 Neuroptera (Neuroptera Chrysopidae.

Abstract The objective was to evaluate the residual action of the insecticides acetamiprid + etofenprox, spinetoram, indoxacarb and methoxyfenozide on the predator Chrysoperla externa Hagen, 1861 (Neuroptera: Chrysopidae). The bioassays followed the methodologies proposed by the International Organization for Biological and Integrated Control (IOBC). The insecticides were sprayed on grapevine plants cv. Burgundy, using the maximum recommended field dosage for fruit trees. Larvae and adults of the predator were exposed to leaves containing the insecticide residues, at 3, 10, 17, 24 and 31 days after spraying, to determine the residual effect on the following biological parameters: mortality, fecundity and fertility. Based on the toxicity observed during the bioassays, the insecticides were classified according to the IOBC persistence scale. Spinetoram was classified as moderately persistent to larvae and slightly persistent to adults, indoxacarb also he was consideredpersistent for larvae and as a short-lived for the adult stage of the lacewing, thus showing the difference in susceptibility between the stages of development of C. externa. The insecticides acetamiprid + etofenprox and methoxyfenozide are the most suitable for ecologically safe application, in areas where the predator occurs because they are classified as short-lived insecticides for the larval and adult stages of C. externa. spinetoram Hagen 186 Neuroptera (Neuroptera Chrysopidae.

ABSTRACT The Empididae fauna of Chile is basically known from a taxonomic perspective. Herein, we have added biological data based on a species of Hilarini, improving our knowledge regarding the southern temperate fauna of the family. We report for the first time the prey and nocturnal activities of the Patagonian empidid species Hilarempis sigillata Collin, 1933. Specimens were collected until two hours after sunset on a white light sheet at a river margin in the Chilean region of Los Lagos, close to the Puyehue National Park. Adults were found on the sheet with prey of the Chironomidae genera Cricotopus, Xestochironomus, Microtendipes, Podochlus, Heptagyia and Reissmesa (Diptera), as well as a species of the Coniopterygidae genus Semidalis (Neuroptera) and a species of the Limoniidae genus Erioptera (Diptera). The empidids held the prey close to their body using the mid tarsi, in most cases with the ventral side of the prey turned up or laterally.

ABSTRACT Frankliniella occidentalis is a pest persistent that attacks the Mexican lemon fruit. Given this, the effect of biorational insecticides on thrips pest management and the impact on natural enemies for the cultivation of Mexican lemon in Michoacán, Mexico, was evaluated, in a completely randomized design, with twelve treatments and ten repetitions; the experimental unit was a tree. The variance data homogeneity test, ANOVA, and Tukey’s comparison of means (p ≤ 0.05) were applied. In the data collection, a previous sampling was done as the starting point of the study and comparison. After treatments, samples were taken at 3, 6, 12, 20, 26, 35, and 41 days later. The study variables were: 1) the number of Frankliniella occidentalis thrips; 2) The number of Olla v-nigrum lady beetles (Coleoptera: Coccinellidae); 3) The number of lacewings Chrysoperla rufilabris (Neuroptera: Chrysopidae); 4) The number of phytoseiids [predatory mites] Phytoseiulus persimilis (Acari: Phytoseiidae). Garlic extract + chamomile and rue extract reduced the thrips population by 58.47; 9.30; 71.43; 40.20; 50.17; 90.37 and 99.67 % at 3, 6, 12, 20, 26, 35, and 41 days after application, respectively. Tolfenpyrad reached its greatest effect by reducing the coccinellid population by 100 % at 3, 6, 12, 26, and 41 days after application. Garlic oil proved to be a good option for thrips control by reducing its population by an average of 60 % and increasing phytoseiid mites by 800 %.
