Behaviour Differences in Two Strains of Aëdes aegypti

Abstract

ATTENTION has recently been directed to differences in the hatching response between eggs of a West African strain of the mosquito Aëdes (Stegomyia) aegypti (L.) from Lagos, Nigeria, and those of an East African strain of the same species from Newala, Tanganyika¹. Further work on these two strains now discloses differences affecting behaviour of the adults: in the Lagos strain, unmated females usually lay eggs within five days of taking a blood meal; in the Newala strain, unmated females rarely lay eggs within this period (Table 1).
