Abstract
Studies on the intensity of successful parasitism and development of progeny of P. nephantidis reared on different instars of O. arenoselta catetpillars revealed that the stage of the host larvae used was critical in determining the acceptance by the parasitoid, number of eggs laid, number of offsprings developed and the proportion of males in the brood. Fifth and early Sixth instar caterpillars of O. arenosella were ideal stages of the host for large scale multiplication of P. nephantidis in the laboratory. The parasitoid was found to be capable of suppressing the early instar caterpillars of the pest by stinging, even though they were not ideal stages for the development of a good number of parasitoids.
