Abstract: An attempt was made to achieve low environmental risk control of insect pests using sublethal concentrations of insecticides, enhanced by the effect of high temperatures (>25°C). For each of the insecticides imidacloprid, abamectin, pirimicarb and azadirachtin, the lethal and sublethal concentrations were determined for the green peach aphid Myzus persicae (Sulzer) (Homoptera: Aphididae) and its predator, the lady beetle Harmonia axyridis (Pallas). The lady beetle was more tolerant of all four insecticides, as well as of high temperatures below 40°C, compared with the prey. The joint action of sublethal concentrations of insecticides and high temperatures was investigated to determine the sublethal concentrations and temperatures that would be effective in controlling the aphids, but not detrimental to the beneficial lady beetle. The results suggested a synergistic effect of sublethal insecticide concentrations and high temperatures against the green peach aphid.
