Abstract

The parasitizing efficiency of the egg parasitoid, Trichogramma pretiosum on Leucinodes orbonalis was studied under laboratory conditions during two different seasons, Kharif, 2013 and Rabi, 2014. The results showed that parasitism and emergence rate of T. pretiosum was 91.9 and 87.5%, respectively, during Kharif, 2013 at 25°C compared to 41.5 and 35.6%, respectively, during Rabi season on one-day old eggs. It was noted that the parasitoid, T. pretiosum preferred one-day-old eggs of L. orbonalis for parasitism during both the season compared to 2- or 3-days old eggs. The results indicated usefulness of T. pretiosum in parasitizing eggs of L. orbonalis.
