Abstract

      Laboratory experiments were conducted on Trichogramma evanescence immatures to detect their response to rearing and development under non-laboratory conditions mainly in cold weather and to detect the efficiency of resulting females. Rearing laboratory conditions were the controls. Hatching periods, adult emergence percentage, female’s ratio in progeny, fecundity, longevity, general productivity, parasitization efficiency and the reduction in parasitization efficiency were investigated. Trichogrammatids emerged from both treatments were nearly similar in the investigated parameters except the hatching period which were prolonged about three times for those reared under non-laboratory conditions compared to the controls. The results revealed that, T. evanescence could be developed successfully under non-laboratory conditions.
