Abstract
Trichogramma cacoeciae Marchall, T. brassicae Bezdenko and T. evanescens Westwood could be useful in biological control programmes of agricultural insect pest. The possibility of storing adult Trighogramma species at low temperatures, and the effect of such storage on the quality of the parasitoids and its fecundity were studied. Trighogramma cacoeciae, T. brassicae and T. evanescens adults were stored for 1, 2, 3, 4 and 5 days at 4 ± 1°C in a refrigerator, 60 – 70%RH and full darkness. Storage at 4 ± 1°C reduced fecundity and longevity of female parasitoids.
