Populations of the bollworm, Heliothis zea (Boddie), and the tobacco budworm, H. virescens (F.), and 8 arthropod predators were studied following in-furrow and sidedress applications of aldicarb and foliar applications of monocrotophos to cotton. In

Sevin, Geigy 30494, toxaphene, Strobane, and toxaphene plus DDT were equally effective against thrips ( Frankliniella spp.). Toxaphene plus DDT gave significantly better control of the cotton fleahopper (Psallus seriatus (Reuter)) than toxaphene alon

Trapping studies were conducted in a large field cage and in the field as part of a coordinated effort to develop a formulation that would control the release of grandlure, the synthetic pheromone of Anthonomus grandis Boheman. From these and related
