Cold storage of some natural enemies of citrus mealybug, Planococcus citri (Risso) (Homoptera: Pseudococcidae).
Storage of Cryptolaemus montrouzieri, Nephus includens, Leptomastix dactylopii and Leptomastidea abnormis was studied at 7, 15 and 25°C and 70% RH. Adults of C. montrouzieri and N. includens could be stored for longer periods at 15 than at 7°C. The presence of prey during storage had a positive effect on longevity. Adults of Leptomastix dactylopii and Leptomastidea abnormis could also be stored for longer at 15 than at 7 or 25°C.
