Meyerdirk, D.E., French, J.V., Hart, W.G., & Chandler, L.D. 1979 Citrus mealybug: effect of pesticide residues on adults of the natural enemy complex.. Journal of Economic Entomology 72: 893-895.

Notes: Four parasites of the citrus mealybug, Planococcus citri (Risso), which included Pauridia peregrina, Leptomastix dactylopii, Leptomastidea abnormis and Anagyrus pseudococci and two predators Cryptolaemus montrouzieri and Sympherobius barberi were exposed for 24 h to pesticide residues on leaves of commercially treated citrus in Texas. L. abnormis and P. peregrina were the most susceptible species tested while C. montrouzieri was the most tolerant.
