Anopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of per year on American continent. diverged from African and Asian vectors ∼100 years ago (mya) successfully adapted to New World environment. Here we present an annotated reference A. genome, sequenced wild population males females collected in Brazilian Amazon. A total 10 481 predicted protein-coding genes were annotated, 72% which have their closest counterpart gambiae 21% highest...
The black soldier fly (Hermetia illucens) is the most promising insect candidate for nutrient-recycling through bioconversion of organic waste into biomass, thereby improving sustainability protein supplies animal feed and facilitating transition to a circular economy. Contrary conventional livestock, genetic resources farmed insects remain poorly characterised. We present first comprehensive population characterisation H. illucens. Based on 15 novel microsatellite markers, we genotyped...
Social bees harbor conserved gut microbiotas that may have been acquired in a common ancestor of social and subsequently codiversified with their hosts. However, most this knowledge is based on studies the honey bumblebees. Much less known about third diverse group bees, stingless bees. Specifically, absence genomic data from presents an important gap understanding evolution functional diversity bee microbiota. Here, we combined community profiling culturing genome sequencing bacteria six...
Cellulolytic enzymes of microbial origin have great industrial importance because their wide application in various sectors. Fungi are considered the most efficient producers these enzymes. Bioprospecting survey to identify fungal sources biomass-hydrolyzing from a high-diversity environment is an important approach discover interesting strains for bioprocess uses. In this study, we evaluated production endoglucanase (CMCase) and β-glucosidase, lignocellulolytic complex, produced by native...
Honeys are described possessing different properties including antimicrobial. Many studies have presented this activity of honeys produced by Apis mellifera bees, however activities stingless bees scarce. The aim study was to compare the antimicrobial collected in Amazonas State from Melipona compressipes, seminigra and against Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Chromobacterium violaceum, Candida albicans. Minimum inhibitory concentrations were determined using...
Many factors have contributed to reductions in wild populations of stingless bees, such as: deforestation, displacement and destruction nests by honey gatherers, as well use insecticides other agrochemicals. All these can potentially affect the populational structure native species. We analyzed genetic variability Melipona scutellaris, based on five microsatellite loci, using heterologous primers M. bicolor. Samples were taken from 43 meliponaries distributed among 30 sites four northeastern...
ABSTRACT Filamentous fungi have been targeted by bioprospecting studies because they are effective producers of extracellular enzymes that can potentially be used the bioindustry. In this study, we isolated filamentous from guts Amazonian aquatic insect larvae to evaluate their cellulolytic activity. We collected 69 shredder insects three genera: Phylloicus (Trichoptera: Calamoceratidae), Triplectides Leptoceridae) and Stenochironomus (Diptera: Chironomidae) in ten streams a protected area...
The diploid male has already been recorded for Melipona Illger, and herein, in seminigra merrillae Cockerell interrupta manaosensis Schwarz. This paper was carried out at the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus, AM, Brazil. We produced monitored 31 new colonies of M. s. 32 i. . sampled 2,995 pupae 2,020 In with a 1 : sex ratio, diploidy confirmed by cytogenetic analysis workers’ behavior. estimated 16 sex-determining alleles 22 workers killed males queen that them soon...
Cytogenetic analysis of the Amazon stingless bee Melipona seminigra merrillae, by conventional Giemsa staining and C-banding, revealed a different chromosome number for Melipona: 2n = 22 females diploid drones while haploid present n 11. There is no evidence B chromosomes. This result contrasts with previous studies, in which 19 species was determined as 18 9 males. Based on cytogenetic information available other species, we propose that M. s. merrillae has more derived number. indicates...
Social organization in highly eusocial bees relies upon two important processes: caste differentiation female larvae, and age polyethism adult workers. Juvenile Hormone (JH) is a key regulator of both processes. Here we investigated the expression genes involved JH metabolism - mfe (biosynthesis) jhe (degradation) context social stingless bee Melipona interrupta. We found evidence that related to changes levels during late larval development, where determination occurs. Also, were...
SummaryThe knowledge of digestive processes correlated with the species plant used by stingless bees is important for development Meliponiculture, or bee keeping, which a lucrative activity in Brazilian Amazon. The number and state digestion pollen grains midgut rectum, as well pollinic diversity some enzymes, were analyzed different life stages Melipona seminigra to compare difference process larvae, adult workers (nurse forager) virgin queens Amazon bees. Pollen consumption was found be...
The stingless bee Melipona (Michmelia) seminigra Friese is a polytypic species widely distributed in Brazilian Amazon and Bolivia.Seven subspecies are recognized, four described, which inhabit mutually exclusive areas the basin, although zones of hybridization recorded.The three other subspecies, despite being recognized by taxonomists undescribed.Melipona good honey-producer an important pollinator native fl ora crops.Partial DNA sequence cytochrome c oxidase subunit 1 (COI) mitochondrial...
ABSTRACT Obtaining colonies of stingless bees in the wild for formation or expansion meliponaries and other purposes is permitted by law Brazil using bait containers trap nests, non-destructive methods. We tested efficiency nests made from plastic bottles attraction nesting central Brazilian Amazon. used 2-L 5-L three types attractants (cerumen geopropolis Melipona seminigra, M. interrupta a mix two). 216 distributed experimental areas during 13 months. Visitation six species 58 (26.9%) 12...
A small plasmid named pEA1 was isolated from Enterobacter agglomerans, an endophytic bacterium colonizing Copaifera multijuga (copaiba). The sequence determined by using the primer walking strategy and deposited in GenBank (accession number DQ659147). is a circular molecule with length of 2,545 bp. Sequence analysis showed this has GC content 34% (Guanine Citosine DNA sequence) contains four open reading frames (ORFs) capacity encoding more than 100 amino acids. ORF1, ORF2, ORF3 homology to...
