Abstract
Field experiments were carried out between 1987–1989 at a location with extremely high population densities of aphids. The performances of pirimicarb, pyrethrum, dichlorvos, cycloprothrin in combination with an alarm pheromone were compared with commercial dosages of the insecticides to control the aphids in iceberg lettuce. After planting, various doses and spray intervals were applied to control the aphids. A spray application of carbamate or organic phosphate at one‐tenth of the recommended dose in combination with the pheromone was successful in controlling the aphids. The farnesene formulation appears to have an alarm effect on aphids as well as hormonal and mortality effects.
