Abstract

Plastanoxus westwoodi (Kieffer), an ectoparasitoid of the larvae and pupae of flat grain beetle, Cryptolestes pusillus (Schoenherr), was evaluated experimentally by infesting 625g kibbled wheat in a plastic container with 100 pairs of the beetles and at 35 days after introducing 0, 5, 10, 20, 30, 40 and 50 mated females of the parasitoids. Samples taken 180 days after the parasitoid was introduced showed P. westwoodi had reduced the population growth of the beetle by at least 43.08% even when only 5 mated females were introduced and by 81.31% when 50 mated females were introduced. The pest emergence was very high in the control container. Minimum pest emergence and maximum parasitism were achieved by introducing 50 mated females per container.
