Journal ArticleDOI
Deltamethrin-mediated survival, behavior, and oenocyte morphology of insecticide-susceptible and resistant yellow fever mosquitos (Aedes aegypti)
Nadja Biondine Marriel,Hudson V. V. Tomé,Raul Carvalho Narciso Guedes,Gustavo Ferreira Martins +3 more
TL;DR: The present study illustrated the different responses of susceptible and resistant strains of A. aegypti following exposure to sublethal concentration of deltamethrin, and demonstrated how the behavior of the immature stage of the two strains varied, as well as oenocyte structure following insecticide exposure.
Journal ArticleDOI
Multiple Modes of Action of the Squamocin in the Midgut Cells of Aedes aegypti Larvae.
Marilza da Silva Costa,Sérgio Oliveira de Paula,Gustavo Ferreira Martins,José Cola Zanuncio,Antônio Euzébio Goulart Santana,José Eduardo Serrão +5 more
TL;DR: This study evaluated the changes in the cell morphology, and in the expression of genes, for autophagy (Atg1 and Atg8), for membrane ion transporter V-ATPase, and for water channel aquaporin-4 (Aqp4) in the midgut of A. aegypti larvae exposed to squamocin from Annona mucosa Jacq.
Journal ArticleDOI
Spinosad-mediated effects on survival, overall group activity and the midgut of workers of Partamona helleri (Hymenoptera: Apidae)
Renan dos Santos Araújo,Marcos Pereira Lopes,Wagner Faria Barbosa,Wagner Gonzaga Gonçalves,Kenner Morais Fernandes,Gustavo Ferreira Martins,Mara Garcia Tavares +6 more
TL;DR: It is demonstrated that spinosad negatively affects individual survival, general group activity and the midgut epithelium of P. helleri and the brain, on the other hand, did not present significant alterations under the tested conditions.
Journal ArticleDOI
Behavior and gut bacteria of Partamona helleri under sublethal exposure to a bioinsecticide and a leaf fertilizer
Lorena L. Botina,Mayra Vélez,Wagner Faria Barbosa,A.C. Mendonça,Victor Satler Pylro,Marcos Rogério Tótola,Gustavo Ferreira Martins +6 more
TL;DR: Sublethal exposure to CuSO4 induces changes in respiration, and spinosad changes the abundance of gut microorganisms of P. helleri, which is an important pollinator in the Neotropical region.
Journal ArticleDOI
The antennal sensilla of Melipona quadrifasciata (Hymenoptera: Apidae: Meliponini): a study of different sexes and castes
Samira Veiga Ravaiano,Ríudo de Paiva Ferreira,Lucio Antonio de Oliveira Campos,Gustavo Ferreira Martins +3 more
TL;DR: The antennal sensilla of females, males, and queen-like males (QLMs) in the stingless bee Melipona quadrifasciata are compared to show the composition and size of the sensilla most closely resemble those of the 2n male, although QLMs exhibit a queen phenotype.
