Humoral inhibition of host-seeking in Aedes aegypti during oocyte maturation.
Autor(es): Klowden M J; Lea A O
Resumo: Female Aedes aegypti mosquitoes were given 1 ?l blood enemas, and their subsequent host-seeking behaviour determined in an olfactometer. Those females failing to develop eggs consistently responded to a host stimulus whenever tested, but inseminated mosquitoes developing eggs were inhibited from host-seeking during the period of egg development. Gravid uninseminated mosquitoes were also inhibited, but not to the same degree as inseminated mosquitoes. Experiments involving surgical manipulations and haemolymph transfusions indicate that a haemolymph-borne substance, present during egg development, inhibits the response toward a host
