Occurrence of Toxorhynchites guadeloupensis (Dyar & Knab) in oviposition trap of Aedes aegypti (L.) (Diptera: Culicidae)

Abstract

Tx. guadeloupensis using Ae. aegypti oviposition traps as breeding places. This Ae. aegypti density is a basic variable in dengue prediction. Whether predation of Ae aegypti by Tx. guadeloupensis may be a cause for underestimation of the actual Ae aegypti numbers. Together these hypotheses need to be better investigated as they are directly related to dengue epidemiology, to the success of any outbreak prediction and surveillance program.

The Insect Microbiome Modulates Vector Competence for Arboviruses

“…For gut bacteria which, unlike Wolbachia , are unable to drive themselves into a population, achieving sustained delivery to mosquitoes in nature remains an important and understudied practical issue. Existing measures for mosquito population control such as oviposition traps, spraying of toxins or insect pathogens, and artificial nectar bait [ 164 , 165 , 166 , 167 , 168 , 169 ] can be adapted as dissemination strategies; however, continued release may be required to maintain these microbiota in the mosquito population.…”
