Abstract
Forty candidate and several commercial insecticides were tested in the laboratory at Tucson, Arizona, in 1959 and 1960 to compare their effectiveness against Lygus hesperus. Bayer 25141 (O,O-diethyl O- p methylsulfinyl phenyl phosphorothioate), 11 other Bayer compounds, Shell SD-4402 (l,3,4,5,6,7,8,8-octachloro-3a,4,7,7a-tetrahydro-4,7-methanophthalan), 2 other Shell compounds, Dupont 691 O-ethyl-O-(p-methylthio) phenyl methylphosphonothioate, Niagara 5943 (N[image],N[image],N[image], N[image]-tetramethyl-N-3-(5-phenyl-(4H)-l,2,4-triazolyl) phosphorotriamide-2 and Stauffer R-1504 (O.O-dimethyl S-phthalimidomethyl phosphoro-dithioate 2) were promising. Commercial insecticides that were highly effective were Dibrom (1,2-dibromo-2,2-dichloroethyl dimethyl phosphate), dimethoate, Dylox (O,O-dimethyl (2,2,2-trichloro-l-hydroxyethyl)phosphonate), endrin, malathion, Methyl Trithion (O,O-dimethyl S- p-chlorophenylthiomethyl phosphorodithioate), and phosphamidon. A Sevin (1-naphthyl N-methylcarbamate)-sulfur dust combination was only moderately effective but was considerably more so than Sevin spray.
