Abstract
Foliar applications of highly laboratory-bioactive hexane body scale extract from Phthorimaea operculella (Zeller) and methanol scale extract from Spodoptera exigua (Hübner) at rates of 9.4 and 4.7 g scale equivalents per ha, respectively, on pesticide-free cotton fields infested with Pectinophora gossypiella (Saunders) produced no significant effect on parasitization of this host by the egg-larval parasite, Chelonus sp. nr. curvimaculatus Cameron. The substantial foliar coverage with the kairomone may have caused parasite distraction on host egg-free foliage, habituation from prolonged kairomone exposure without the reinforcement of host finding and early dispersal from treated plots.
