The toxicity of N insecticidal sprays against onion thrips, Thrips labaci Lindeman, was compared in fIeld experiments in southern California. Effective control of larvae was obtained with carbaryl, G-30494 [S- (2,5-didllo- rophenylthio) methyl O,O-dimethyl phosphorodithioate], azinphosmethyl; fenthion; endosulfan; Imidan® (O,O-di methyl S-phthalimidomethyl phosphorodithioate), and DDT. Control with carbaryl, DDT, ethion, G-30494, azinphosmethyl, or Imidan was not improved by the addition of an oil emulsion. A]so, control was not improved by ing Plyac® spreader to carbaryl sprays or WARF antiresistant (N,N-dibutyl-p-chlorobenzenesulfonamide) to DDT.
