Jayaraman, V., Chandramohan, N., Gopalan, M., & Balasubramanian, G. 1988 Predatory potential of coccinellid beetles on mealybugs of citrus and grapevine.. Madras Agricultural Journal 75(1-2): 77-78.

Notes: The predatory potential of adults of the coccinellids Cryptolaemus montrouzieri and Scymnus coccivora on eggs, nymphs and adults of the pseudococcids Planococcus citri and Maconellicoccus hirsutus was assessed in the laboratory at 27.7-30.5°C and 57-93% RH. The feeding rate of C. montrouzieri was higher than that of S. coccivora for all prey stages. Females of C. montrouzeri consumed more of all stages of the prey during their lifespan than males, and the predation rate of both sexes was higher on P. citri than on M. hirsutus. The rate of predation on the prey stages was greatest for eggs, followed by nymphs and then adults.
