ABSTRACT
Study on the compatibility of different concentrations of neem seed extract with Trichogramma (Hymenoptera: Trichogrammatidae) was conducted at Nuclear Institute for Food and Agriculture (NIFA) Tarnab, Peshawar, during 2004. Among different concentrations of neem seed extract (4%, 2%, 1%, 0.5% and 0.25%), maximum mortality (68.29%) of Trichogramma was recorded with 4% neem seed extract and minimum (35.83%) with 0.25% neem seed extract. However the highest mortality (97.52%) of Trichogramma was recorded with Ripcard 0.5%. Emergence time was non significantly different in all treatments of neem seed extract but was significantly different from Ripcard where the emergence time was 9.75 days. Longevity and sex ratio was also non significantly different in all treatments of neem seed extract.
