Dengue, yellow fever, Zika and Chikungunya viruses are more important arboviruses transmit by mosquitoes. A. aegypti life cycle goes through 4 stages of development and the time for development from egg to adult mosquito depends on a series of biotic and abiotic factors such as temperature, food availability and population density, studied in different species of insects. In this work we studied the effects of different food concentrations, temperatures variation, pH gradient and luminosity on the development of A. aegypti larvae. The eggs were collected in the city of Tangará da Serra/MT and larvae in the L1 stage were used for the tests. The results showed that all the factors studied interfered in the larval development. The increase in food concentration and temperature accelerated the development of larvae to pupae. The acidic pH (pH = 4) proved to be unsuitable for the development of larvae (100% lethality), with the ideal pH for the development of larval stages being equal to pH = 6. Although in all light variations (dark, light and photoperiod 10L/ 14D) there was complete development of the larvae, the photoperiod test proved to be more adequate. This study helps to better understand the success, dispersion and adaptation of the A. aegypti mosquito in different regions under different environmental conditions.","PeriodicalId":11746,"journal":{"name":"EntomoBrasilis","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88145572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Brazil, few taxonomic, ecological or evolutionary studies have been published in recent years, the reason is related to the few number of researchers dedicated to this particular group. Cladomorphus phyllinus Gray is one of the largest Brazilian insects and perhaps one of the most studied species of Phasmatodea in the country. It is considered as a phytophagous, generalist, and feeds mainly on guava leaves (Psidium guajava), powder-puff (Calliandra sp.) or Angico (Piptania sp.). Females of this species reproduce in a sexual and asexual manner, by the production of diploid daughters from unfertilized eggs (thelytokous parthenogenesis). The absence of records on the reproductive capacity of virgin parthenogenetic females of C. phyllinus led us to record the longevity, fertility, and eggs viability of ten specimens. The results obtained were compared to those found in the scientific literature for mated females of the same species. The fertility and eggs viability were observed to be much lower for the parthenogenetic females when compared to the mated females; however, the longevity for virgin females was longer than that recorded in the literature for mated females.","PeriodicalId":11746,"journal":{"name":"EntomoBrasilis","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75355397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Amazon has been changing due to economic activities such as mining, logging, agriculture, and urbanization, leading to changes in malaria transmission patterns in this region. Therefore, this study aimed to survey Anopheles species in a peri-urban area of Macapá, state of Amapá, Eastern Amazon, Brazil. Human landing catches (HLC) and Shannon light traps were used to collect Anopheles adults at three points. We screened breeding sites in all accessible water reservoirs within a 2 km radius of each collection point to collect immatures and found two species: Anopheles (Nyssorhynchus) albitarsis s.l. Lynch-Arribalzága (35.7%) and Anopheles (Nyssorhynchus) braziliensis (Chagas) (64.3%). A total of 267 winged specimens of Anopheles were collected: A.

The aim of the study was to evaluate the effect of different levels of artificial defoliation performed in the vegetative and reproductive stages of two soybean cultivars, FT Campo Mourão and Brasmax Potência. The treatments consisted in: 1) Without defoliation throughout the culture cycle; 2) 16.7% defoliation in the vegetative stage; 3) 33.3% on vegetative stage; 4) 16.7% on reproductive stage; 5) 33.3% on reproductive stage; 6) 16.7% throughout the soybean cycle; 7) 33.3% defoliation throughout the soybean cycle. Regardless of the level of defoliation performed on soybeans, it was found that the cultivar Brasmax Potência presented the higher values of plant height, number of pods/plant and green weight of the aerial part, when compared to cultivar FT Campo Mourão. However, the number of pods/plant, green weight of the areal part, grain yield and weight of the seeds were not influenced by the defoliation intensities applied to the soybean. Based on the results, the threshold level of 30% of defoliation in the vegetative stage or 15% in the reproductive stage of soybean is still considered valid for the control of defoliating caterpillars in soybean crop.","PeriodicalId":11746,"journal":{"name":"EntomoBrasilis","volume":"146 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88645276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This situation occurs in two important biomes in Brazil, the Atlantic Forest and the Cerrado. There is little information on the effects of fragmentation on animal taxa, including social wasps. It was hypothesized that fragments that are small in size and subject to anthropogenic pressures have reduced social wasp richness and colony numbers. This study aimed to investigate the effect of forest fragmentation on Polistinae richness and colony number at Atlantic Forest and Cerrado sites in southern central Minas Gerais State, southeastern Brazil. The study was conducted in three fragments, Mata do Baú, Cachoeira da Lajinha, and Cachoeira do Padeiro, from October 2020 to March 2021, using active collection to record social wasp species and colony numbers. A total of 42 species and 80 colonies were recorded in the three fragments. Forest fragment size alone did not influence social wasp communities, but communities were significantly affected by a combination of factors, including fragment size, adjacent vegetation, and anthropogenic pressures. Species richness was higher in Mata do Baú and Cachoeira da Lajinha, which did not differ from each other, than in Cachoeira do Padeiro; however, all fragments had exclusive communities. Therefore, an increase in anthropogenic pressure in any of the three fragments may lead to losses in social wasp species.","PeriodicalId":11746,"journal":{"name":"EntomoBrasilis","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74492798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
