Abstract

Aldrin, p,p'-DDT, dieldrin, gamma chlordane. heptachlor, heptachlor epoxide, J-hydroxychlordene, and lindane were bioassayed against larvae of Anopheles quadrimaculatus Say; the remnant amounts of insecticide and metabolites in larvae and medium were determined by electron-affinity gas chromatography. The insecticides were surprisingly nonpersistent at concentrations normally used.
