The selective toxic insecticidal properties of pirimicarb, carbaryl and methamidophos to the green peach aphid, Myzus persicae (Sulzer), and its predators, Coleomegilla maculata lengi (Timberlake) and Chrysopa oculata (Say) were studied. Pirimicarb was less toxic than carbaryl and methamidophos to C. maculata and C. oculata and more toxic to aphids. The selectivity ratio for pirimicarb indicating selectivity favoring the predators was ca. 4000:1.
