Unusual Microbial Xylanases from Insect Guts
(2004-06-07)
Recombinant DNA technologies enable the direct isolation and expression of novel genes from biotopes containing complex consortia of uncultured microorganisms. In this study, genomic libraries were constructed from microbial ...
Evaluation of hydrolytic enzyme activities from digestive fluids of Anthonomus grandis (Coleoptera: Curculionidae)
(Wiley-liss, div John Wiley & Sons Inc., 2020-08)
The cotton boll weevil, Anthonomus grandis, is a major pest of cotton crops in South America. In this work, partial biochemical characterizations of (hemi) cellulases and pectinases activities in the digestive system (head- ...
Gut bacteria facilitate adaptation to crop rotation in the western corn rootworm
(Natl Acad Sciences, 2013-06)
Insects are constantly adapting to human-driven landscape changes;
however, the roles of their gut microbiota in these processes remain
largely unknown. The western corn rootworm (WCR, Diabrotica virgifera
virgifera ...
Artificial selection, pre-release diet, and gut symbiont inoculation effects on sterile male longevity for area-wide fruit-fly management
(Wiley, 2015-12)
Longevity is an important life-history trait for successful and cost-effective application of the sterile insect technique. Furthermore, it has been shown that females of some species – e.g., Anastrepha ludens (Loew) ...
Molecular Gut-Content Analysis of Adult Ground Beetles (Coleoptera: Carabidae) Provides No Evidence of Predation of Western Corn Rootworm (Coleoptera: Chrysomelidae) in a Nebraska Corn Agroecosystem
(Georgia Entomological Soc Inc, 2020-10-01)
This study was conducted to characterize the ground beetle (Coleoptera: Carabidae) community in Nebraska continuous cornfields and investigate the potential for predation of the western corn rootworm, Diabrotica virgifera ...
Modulation of IMD, Toll, and Jak/STAT Immune Pathways Genes in the Fat Body of Rhodnius prolixus During Trypanosoma rangeli Infection
(Frontiers Media, 2021-01)
Trypanosoma rangeli is the second most common American trypanosome that infects man. It is vectored by triatomines fromthe genusRhodnius, in which it invadesthe hemolymph and infects the salivary glands, avoiding the bug ...
First isolation of microorganisms from the gut diverticulum of Aedes aegypti (Diptera: Culicidae): New perspectives for an insect-bacteria association
(2007-12-01)
We show for the first time that the ventral diverticulum of the mosquito gut (impermeable sugar storage organ) harbors microorganisms. The gut diverticulum from newly emerged and non-fed Aedes aegypti was dissected under ...
