Comparative study on the efficacy of nine Trichogramma species (Hymenoptera: Trichogrammatidae) on the eggs of Leucinodes orbonalis (Lepidoptera: Crambidae)

RF Niranjana, M Devi and R Philip Sridhar

The parasitism efficiency through sexual and parthenogenesis reproduction and emergence rate of nine different egg parasitoids belong to the Genus Trichogramma viz., T. pretiosum, T. embryophagum, T. achaeae, T. japonicum, T. brassicae, T. mwanzai, T. chilonis, T. dendrolimi and T. evanescens on the eggs of Brinjal Shoot and Fruit Borer, Leucinodes orbonalis was studied in laboratory condition during three different seasons, Kharif, 2013 (August to September 2013), Rabi, 2013 (November to December 2013) and summer, 2014 (March to April 2014). The results revealed that the parasitoids, T. pretiosum and T. embryophagum had the highest parasitism efficacy against one-day old eggs of L. orbonalis during Rabi, 2013 (27°C ± 5°C) with 92.01 and 90.02 per cent respectively. The study evidenced the superiority of T.embryophagum with maximum emergence rate (90.22 per cent) and greatest ability to parasitize an average of 11.21 eggs of L. orbonalis through parthenogenesis reproduction.
