Abstract

Aldrin, p,p’-DDT, dieldrin, gamma chlordane, heptachlor, heptachlor epoxide, 1-hydroxychlordene, and lindane were biassayed against larvae of Anopheles quadrimaculaus Say; the remnant amounts of insecticide and metabolites in larvae and medium were determined by electron-affinity gas chromatography. The insecticides were surprisingly nonpersistant at concentrations normally sued.
