Abstract

The effect of multiple immersions on Haemagogus janthinomys check for this species in other resources , Haemagogus leucocelaenus check for this species in other resources , Aedes albopictus check for this species in other resources and Ochlerotatus terrens check for this species in other resources eggs was studied. Eggs were collected in April, June, October and December of 2011 in Minas Gerais, Brazil. Most of the Aedes and Ochlerotatus eggs hatched upon the first immersion, while Haemagogus eggs showed a varied instalment hatching response. The number of immersions required for hatching increased for eggs collected closer to the dry winter season.
