Journal ArticleDOI

TL;DR: In this paper , the authors investigated how the gut bacterial community of Rhipicephalus microplus is shaped after Metarhizium anisopliae treatment and how the tick susceptibility to the fungus is affected after disrupting gut bacterial microbiota.
Journal ArticleDOI
Exposure of newly deposited Aedes aegypti eggs to Metarhizium humberi and fungal development on the eggs.
TL;DR: In this paper , the sensitivity of newly deposited eggs to Metarhizium humberi IP 46 conidia was explored, and it was shown that exposure of eggs oviposited onto a wet, conidium-treated substrate or application of conidia onto eggs within the first 72 h after deposition revealed no clearly higher ovicidal effect caused by pre-germinating or germinating conidia or by further fungal development during this initial phase of chorionic sclerotization and embryogenesis than occurs on fully sclerotic eggs.
Journal ArticleDOI

TL;DR: In this article , entomopathogenic fungi associated with A. aegypti were collected from field-collected mosquito adults (3 strains) or larvae (a single strain); the other 17 strains were isolated from laboratory-reared A. anisopliae sentinel larvae set out in partially immersed cages placed in diverse small to middle-sized aquatic mosquito habitats in or close to areas with secondary tropical forest.
