Laboratory results indicated that acephate, oxydemetonmethyl, and the growth regulator, kinoprene, were highly toxic to adult Pseudococcus longispinus (Targioni-Tozzetti) and Phenacoccus solani Ferris. Methoprene and Ro 10-3108 (7570 2-ethyl-3-[3-ethyl-5- (4-ethylphenoxy) - pentyl]-2-methyloxirane (cis/trans) and 25% 2-ethyl-3- [5 - (4 -ethylphenoxy) -2.3-dimethylpentyl]-2-methyloxirane (cis/trans) were less toxic but reduced reproduction. In greenhouse tests, acephate, oxydemetonmethyl, and kinoprene suppressed populations of both mealybug species and prevented crop damage. Methoprene did not control greenhouse populations; Ro 10-3108 reduced populations but not quickly enough to prevent unsightly damage. Overall reductions of Rhizoecus floridanus Hambleton by kinoprcne and Ro 10-3108 were comparable to the insecticides, acephate and oxamyl. Oxydemetonmethyl and Ro 20-3600 (6,7-epoxy-3-methyl-7-ethyl-1-[3,4- (methylenedioxy) phenoxy]-2-cis/trans-octene) proved less effective.
