Variations in circulating hemocytes are affected by age and caste in the stingless bee Melipona quadrifasciata.
Samira Veiga Ravaiano,Wagner Faria Barbosa,Lucio Antonio de Oliveira Campos,Gustavo Ferreira Martins +3 more
TL;DR: The morphological features and total and differential counts of hemocytes in different female classes (newly emerged workers, nurses, foragers, and virgin queens) of the eusocial stingless bee Melipona quadrifasciata suggest that profiles of hemocyte vary according to the caste and age of this eussocial bee.
Journal ArticleDOI
Midgut morphological changes and autophagy during metamorphosis in sand flies.
Juliana Malta,Matthew Heerman,Ju Lin Weng,Kenner Morais Fernandes,Gustavo Ferreira Martins,Marcelo Ramalho-Ortigao,Marcelo Ramalho-Ortigao,Marcelo Ramalho-Ortigao +7 more
TL;DR: The overall morphological changes of the midgut of the sand fly during metamorphosis are investigated and the expression profiles of the autophagy-related genes ATG1, ATG6, and ATG8, which are associated with various steps of the Autophagic process are assessed.
Journal ArticleDOI
Impact of copper sulfate on survival, behavior, midgut morphology, and antioxidant activity of Partamona helleri (Apidae: Meliponini).
Rodrigo Cupertino Bernardes,Kenner Morais Fernandes,Daniel Silva Sena Bastos,André Filipe Penha Aires Freire,Marcos Pereira Lopes,Leandro Licursi de Oliveira,Mara Garcia Tavares,Renan dos Santos Araújo,Gustavo Ferreira Martins +8 more
TL;DR: In this article, the authors evaluated both lethal and sub-lethal effects of CuSO4 on the stingless bee Partamona helleri, and found that the ingestion of increasing concentrations of CuS4 resulted in altered walking behavior and damage to the midgut epithelium and peritrophic matrix of bees.
Journal ArticleDOI
Morphological features of the heart of six mosquito species as revealed by scanning electron microscopy
TL;DR: This study provides a detailed analysis of the mosquito heart microanatomy and represents a significant contribution towards the understanding of structural-functional relationships associated with the heart of mosquito.
Journal ArticleDOI
The Antennal Sensilla of Species of the Palpalis Group (Diptera: Glossinidae)
TL;DR: It is hypothesized that host-search efficiency could be influenced by the number of olfactory-sensilla types on the antennae, in which case, females present greater potentials.
