ABSTRACT

The anthocorid predator Montandoniella moraguesi Puton. and the eulophid parasitoid Pleurotropis sp . are widely distributed among populations of Gynaikothrips Jicorwn Marchal, as specific control agents against this thrips that infests Ficus ,utida Thumb . in Egypt . The pest, predator and the parasitoid are continually present in Mansoura region during the year where the prey-predator ratios assured the important role of M. moraguesi as a controlling agent of the pest especially during January, February, March , July August and September The percentage of parasitism of Pleisrorropis sp . on host nymphs ranged from 1.6 to 95 % with a general annual rate of 35.18 % The parasitoid was able to reduce more than 50% of the host nymphs during January , February, March and August . The Larvae of Chrysoperla carnea Steph . are also associated with the immature stages of this thrips but with relatively low populations . The development and efficiency of C. carnea on diets of eggs or nymphs of G. ficorum were investigated under laboratory conditions.

Key Words: Ficus nitride Gynaikothrips ficorum. predators, parasitoids.
