Ability of Toxorhynchites amboinensis (Doleschall) (Diptera: Culicidae) to locate and oviposit in artificial containers in an urban environment [Biological control]
An evaluation of the ability of the predaceous species Toxorhynchites amboinensis (Doleschall) to locate and oviposit in artificial containers in an urban environment was conducted in New Orleans, La. Liberations of laboratory-reared males and gravid females resulted in oviposition in virtually every type of container found in such a habitat; causal observation indicated that oviposition was largely independent of the color and the location of the container with respects to vegetation and buildings. Evidence is presented that indicates that the predator females oviposit in response to cues correlated with the presence of prey immatures and that ephemeral habitats such as containers that tend to dry out are less attractive as oviposition sites.
