The effect of multiple immersions on Haemagogus janthinomys
, Haemagogus leucocelaenus
, Aedes albopictus
and Ochlerotatus terrens
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.
