- Abstract
Feeding potential of the coccinellid predator, Cryptolaemus montrouzieri Mulsant in association with eggs, nymphs and adults of Planococcus citri (Risso) as the preference prey showed that, the coccinellid grubs consumed 4538.55, 837.66 and 230.11 individuals, respectively. The predator adult female and male consumed 19420, 17552.4 of P. citri eggs, 1978.6, 1945.8 of P. citri nymphs and 1077, 772.4 of P. citri adults respectively. On the other hand, by using Ephestia eggs as an alternative prey for feeding the predator, data showed that, the coccinellid grubs consumed 1336.6 individuals. The corresponding figures reported for the adult female and male were 9533 and 5622.2 individuals. Results also indicated the ability for using the alternate prey (E. kuehniella eggs) in case of shortage of the preferred prey (P. citri), especially during all developmental periods of the predator, except its ovipositional period because the predator female needs mass eggs of mealy bug to deposit its eggs.
