Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

open access: yesMedical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Mosquito feeding patterns in the context of West Nile and eastern equine encephalitis viruses in eastern Ontario, Canada

open access: yesMedical and Veterinary Entomology, EarlyView.
Mosquitoes in Eastern Ontario, Canada, readily fed on bloodmeal hosts consistent with patterns observed in other regions of North America. Enzootic and bridge vector mosquitoes fed on amplification hosts like American Robins (Turdus migratorius) together with humans, highlighting a potential route for WNV and EEEV transmission to human populations.
