  1. Use chemicals to attract natural enemies

    A controlled, paired study in Egypt (McVeigh et al. 1983) found three times more insect predators in cotton Gossypium sp. fields treated with pink bollworm Pectinophora gossypiella mating-disruption chemicals (sex pheromones) than in controls treated with insecticide. Average daily moth (Lepidoptera) catches were lower and seed cotton yields were higher in fields treated with pheromones than in controls. Three sex pheromone formulations were tested (microcapsules in solution, laminated plastic chips and hollow fibres) but average moth catches and yield were unaffected by these treatments. Pheromone treatments were tested in three 50 ha blocks of cotton, each paired with a 50 ha insecticide-treated control. Natural enemies were monitored by D-vac sampling. Moths were monitored in pheromone-baited traps and by counting infested flowers and cotton bolls. This conference paper did not determine whether natural enemies were attracted to the pheromones or simply benefited from the absence of insecticides.
