1. Mitochondrial genomes of genus Atta (Formicidae: Myrmicinae) reveal high gene organization and giant intergenic spacers
Abstract The ants of the genus Atta are considered important pests to agriculture in the Americas, although Atta species are also important contributors to ecosystem functions in the various habitats in which they occur. The aim of this study was to assemble four complete mitochondrial genomes of the genus Atta, construct the phylogenomic tree, and analyze t

2. The search for novel insecticide targets in the post-genomics era, with a specific focus on G-protein coupled receptors
Insects are considered pests globally, implicated in the destruction of agricultural fields and transmission of pathogens that cause deadly human diseases, such as dengue, Zika and malaria. The diversity of the insecticide arsenal has remained stagnant for decades, but the recent rise of insecticide resistance fueled the discovery of novel modes of action, a

3. NUEVA ESPECIE DE RANA BROMELÍCOLA DEL GÉNERO PRISTIMANTIS (AMPHIBIA: CRAUGASTORIDAE), MESETA DE LA CORDILLERA DEL CÓNDOR, ECUADOR
ABSTRACT We describe a small frog of the genus Pristimantis inhabiting bromeliads (snout-vent length 20.3-23.3 mm in females, 16.1-17.4 mm in males), from a remote sandstone plateau of the Cordillera del Condor, in southeastern Ecuador, with an altitudinal range of 2,045-2,860 m. A phylogeny based on sequences of DNA (mitochondrial and nuclear genes) support

4. The diversity of citrus endophytic bacteria and their interactions with Xylella fastidiosa and host plants
Abstract The bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC) and has been associated with important losses in commercial orchards of all sweet orange [Citrus sinensis (L.)] cultivars. The development of this disease depends on the environmental conditions, including the endophytic microbial community associated with the

5. The rearranged mitochondrial genome of Leptopilina boulardi (Hymenoptera: Figitidae), a parasitoid wasp of Drosophila
Abstract The partial mitochondrial genome sequence of Leptopilina boulardi (Hymenoptera: Figitidae) was characterized. Illumina sequencing was used yielding 35,999,679 reads, from which 102,482 were utilized in the assembly. The length of the sequenced region of this partial mitochondrial genome is 15,417 bp, consisting of 13 protein-coding, two rRNA, and 21

6. Insights into the dynamics of hind leg development in honey bee (Apis mellifera L.) queen and worker larvae - A morphology/differential gene expression analysis
Phenotypic plasticity is a hallmark of the caste systems of social insects, expressed in their life history and morphological traits. These are best studied in bees. In their co-evolution with angiosperm plants, the females of corbiculate bees have acquired a specialized structure on their hind legs for collecting pollen. In the highly eusocial bees (Apini a

7. Differential expression of the pr1A gene in Metarhizium anisopliae and Metarhizium acridum across different culture conditions and during pathogenesis
The entomopathogenic fungi of the genus Metarhizium have several subtilisin-like proteases that are involved in pathogenesis and these have been used to investigate genes that are differentially expressed in response to different growth conditions. The identification and characterization of these proteases can provide insight into how the fungus is capable o

8. Genome-wide comparison of genes involved in the biosynthesis, metabolism, and signaling of juvenile hormone between silkworm and other insects
Juvenile hormone (JH) contributes to the regulation of larval molting and metamorphosis in insects. Herein, we comprehensively identified 55 genes involved in JH biosynthesis, metabolism and signaling in the silkworm (Bombyx mori) as well as 35 in Drosophila melanogaster, 35 in Anopheles gambiae, 36 in Apis mellifera, 47 in Tribolium castaneum, and 44 in Dan

9. Isolation, pathogenicity and disinfection of Staphylococcus aureus carried by insects in two public hospitals of Vitória da Conquista, Bahia, Brazil
Currently, hospital infection is a serious public health problem, and several factors may influence the occurrence of these infections, including the presence of insects, which are carriers of multidrug-resistant bacterial species. The aim of this study was to isolate staphylococci carried by insects in two public hospitals of Vitoria da Conquista, Bahia and

10. Identificação e análise molecular de genes expressos no final do ciclo gonotrófico de Aedes aegypti. / Identification and molecular analysis of genes expressed at the end of Aedes aegypti gonotrophic cycle.
Compreender a fisiologia reprodutiva de Aedes aegypti, vetor primário do vírus dengue, é uma etapa básica para o desenvolvimento de novos métodos de controle. Baseado nesta premissa, estudos de expressão gênica durante o ciclo gonotrófico de Aedes aegypti foram realizados neste trabalho e foram identificados 3 genes com expressão elevada nos ovário

11. Aspectos celulares e moleculares das glândulas salivares e do corpo gorduroso de Rhynchosciara americana durante o desenvolvimento. / Cellular and molecular aspects of salivary glands and fat body of Rhynchosciara americana during development.
Durante o desenvolvimento de holometálobos alguns tecidos são eliminados/remodelados durante a metamorfose. A autofagia age nesse processo degradando componentes citoplasmáticos, inicialmente isolando-os em dupla membrana, estrutura chamada autofagossomo e esses conteúdos são degradados por hidrolases lisossomais. Porém, aspectos apoptóticos podem est

12. Agronomic performance, chromosomal stability and resistance to velvetbean caterpillar of transgenic soybean expressing cry1Ac gene.
The objective of this work was to analyze the agronomic performance and chromosomal stability of transgenic homozygous progenies of soybean [Glycine max (L.) Merrill.], and to confirm the resistance of these plants against Anticarsia gemmatalis. Eleven progenies expressing cry1Ac, hpt and gusA genes were evaluated for agronomic characteristics in relation to
