Abstract Triatominae are recognized as vectors of Trypanosoma cruzi, a protozoan which is the etiological agent of Chagas disease. A specimen of Triatoma delpontei was found at Porto Murtinho in Mato Grosso do Sul State, Brazil. This is the first report of the occurrence of T. delpontei to the state of Mato Grosso do Sul, Brazil. With the present finding, the total number of triatomines recorded in Mato do Grosso do Sul reaches 17 species, while T. delpontei, previously recorded only from Rio Grande do Sul, is now recorded to a second Brazilian state. Based on the information available in the literature, a meticulous and organized compilation has been crafted, highlighting the cytogenetics differentiations of the species occurring in this state. This work emphasizes the importance of continuous research and surveillance on Triatominae, recognized as vectors of T. cruzi. cruzi disease State Brazil T finding 1 literature crafted

ABSTRACT Background: Vector distribution influences arbovirus persistence. This study examined the diversity of mosquito breeding sites in an Atlantic Forest fragment in Rio de Janeiro, Brazil. Methods: Mosquito specimens were collected at Fazenda dos Cordeiros, Silva Jardim, Brazil. Tire, plastic, bamboo, and sapucaia traps were evaluated for oviposition preferences using ecological indices. Results: Tire traps had the highest density. Bamboo traps showed the highest diversity. Plastic container was the most divergent site. The key recorded vector species included Aedes albopictus and Haemagogus leucocelaenus. Conclusions: Identifying the breeding sites that contribute the most to mosquito density is essential for optimizing control strategies.

Abstract The parasitoidism of an adult female of Heniartes jaakkoi Wygodzinsky, 1947 (Hemiptera: Heteroptera: Reduviidae: Harpactorinae: Apiomerini) by a female of Xanthomelanodes cf. brasiliensis Townsend, 1929 (Diptera: Tachinidae: Phasiinae: Gymnosomatini), from Nova Friburgo, Brazil, is recorded. Previous observations of Phasiinae eggs on three species of Harpactorinae had been made, but without record of the parasitoid species. This is the first record of parasitoidism in Reduviidae, including both the host and the parasitoid in the Neotropical region.

Resumen Se registra el parasitismo de una hembra adulta de Heniartes jaakkoi Wygodzinsky, 1947 (Hemiptera: Heteroptera: Reduviidae: Harpactorinae: Apiomerini) por una hembra de Xanthomelanodes cf. brasiliensis Townsend, 1929 (Diptera: Tachinidae: Phasiinae: Gymnosomatini), en Nova Friburgo, Brasil. Se realizaron observaciones previas de huevos de Phasiinae en tres especies de Harpactorinae, pero sin registro de la especie del parasitoide. Este es el primer registro de parasitoidismo en Reduviidae, incluyendo tanto al huésped como al parasitoide en la región neotropical.

ABSTRACT Background: Triatominae are vectors of the protozoan Trypanosoma cruzi, the causative agent of Chagas disease. This study aims to report an infestation on Triatominae colonies by a beetle, previously identified as a pest. Methods: The management of these colonies should be improved to maximize their usefulness, and factors that may cause harm to them should be avoided as much as possible. Results: This is the first report on a coleopteran infestation on living Triatominae colonies worldwide. Conclusions: The present record provides an important warning to researchers who maintain insectaries in general, especially those who rear triatomines, to carry protective measures against such invasions.

Abstract The predatory activities of Apiomerus duckei Costa Lima, Seabra & Hathaway, 1951, Apiomerus pilipes (Fabricius, 1787) and Apiomerus luctuosus Costa Lima, Seabra & Hathaway, 1951 (Hemiptera: Reduviidae: Harpactorinae: Apiomerini) on orchid bees (Hymenoptera: Apidae: Apinae: Euglossini) in odoriferous traps in the influence area of Santo Antonio Hydroelectric Power Plant, Rondonia State, Brazil, and of Cosmoclopius annulosus Stal, 1872 (Hemiptera: Reduviidae: Harpactorinae: Harpactorini) on the bee Ceratina rupestris Holmberg, 1884 (Hymenoptera: Apidae: Apinae: Xylocopini: Ceratinina), in an experimental area cultivated with canola in Passo Fundo, Rio Grande do Sul State, Brazil, are recorded by the first time.

Resumen Se registran por primera vez las actividades depredadoras de Apiomerus duckei Costa Lima, Seabra y Hathaway, 1951, Apiomerus pilipes (Fabricius, 1787) y Apiomerus luctuosus Costa Lima, Seabra y Hathaway, 1951 (Hemiptera: Reduviidae: Harpactorinae: Apiomerini) sobre abejas orquídeas (Hymenoptera: Apidae: Apinae: Euglossini) en trampas odoríferas ubicadas en el área de influencia de la Central Hidroeléctrica Santo Antonio (HEP), Estado de Rondonia, Brasil, y de Cosmoclopius annulosus Stal, 1872 (Hemiptera: Reduviidae: Harpactorinae: Harpactorini) sobre la abeja Ceratina rupestris Holmberg, 1884 (Hymenoptera: Apidae: Apinae: Xylocopini: Ceratinina), en un área experimental cultivada con canola en Passo Fundo, Rio Grande do Sul State, Brasil.

Abstract INTRODUCTION: The occurrence of Microtriatoma borbai in the state of Espírito Santo, Brazil is reported by the first time. METHODS: A triatomine specimen collected in a hybrid eucalyptus crop in the municipality of Aracruz, Espírito Santo state was found to be a male M. borbai. RESULTS: This finding expands the geographical distribution of M. borbai from four to five Brazilian states. It is the first report of M. borbai occurrence inside a eucalyptus crop. CONCLUSIONS: The occurrence of M. borbai in the state of Espírito Santo broadens the geographical distribution of this species in southeastern Brazil.

Abstract INTRODUCTION: Chagas disease is caused by the protozoa Trypanosoma cruzi. Its main reservoir is the domestic dog, especially in rural areas with favorable characteristics for vector establishment and proliferation. The aims of this study were to collect data, survey and map the fauna, and identify T. cruzi infection in triatomines, as well as to assess the presence of anti-T. cruzi antibodies in dogs in rural areas of the municipality of Mossoró, Brazil. METHODS: An active entomologic research was conducted to identify adult specimens through an external morphology dichotomous key. The analysis of natural infection by T. cruzi in the insects was performed by isolation in culture and polymerase chain reaction. The antibody testing for T. cruzi in dogs was performed by enzyme-linked immunosorbent assay and indirect immunofluorescence assay. RESULTS: A total of 68 triatomines were captured, predominantly the Triatoma brasiliensis brasiliensis (Neiva 1911) species. The vector mapping displayed areas with greater risk for parasite transmission. Of the examined triatomines (51 specimens), 41.2% (21/51) were positive on polymerase chain reaction, and all were negative on culture. In the serum testing, 11% (25/218) of dogs were seropositive, but no association was found between the serologic results and the presence and infection by T. cruzi in triatomines. CONCLUSIONS: This study demonstrated the movement of T. cruzi in the studied area, by the presence of vectors and naturally infected domestic reservoirs. The mapping of the studied rural area demonstrates the risk of disease transmission.

Abstract: INTRODUCTION: Environmental modifications caused by human activities have led to changes in mosquito vector populations, and sylvatic species have adapted to breeding in urban areas. METHODS: Mosquitoes were collected using ovitraps in three sampling sites in the Atlantic Forest in the State of Rio de Janeiro, Brazil. RESULTS: We collected 2,162 Culicidae specimens. Haemagogus janthinomys and Haemagogus leucocelaenus, both sylvatic yellow fever virus vectors, were the most common species found. CONCLUSION: There is a potential for the transmission of arboviruses in and around these natural reserves. Therefore, it is necessary to maintain entomological surveillance programs in the region.
