Abstract
Observations of the sexual behavior of laboratory colonies of Aedes triseriatus (Say), a common, tree-hole-breeding mosquito in North America east of the Rocky Mountains, gave the impression that females with a blood meal would copulate more readily than those which had not had blood. It was observed also that blood-fed females averaged 55 sec in the copulating position, whereas the average for non-blood-fed females was 25 sec. (Wright et al. 1966). Thus, males would copulate with both blood-fed and non-blood-fed females, but the incidence of copulations with blood-fed females appeared to be higher. To determine the influence, if any, of the blood meal in relation to copulation, an investigation was undertaken to study the level of insemination in populations of blood-fed and non-blood-fed females of this mosquito.
