In: Mansoura Unviersity Journal of Agricultural Sciences 2005.v.30(4)Summary: The Aphelinid parasitoid Eretmoceros mundus Mercet is considered the most effective parasitoid against Bemisia argentifolii Bellows & Perring, a serious pest in greenhouses and outdoor crops, in Egypt. Studies were carried out to determine some biological characters of Er. mundus under two temperature regimes 25 and 30 °c and 75% R.H. The life cycle of the parasitoid shortened at 30°C (22.3%3.89 days), become longer (27.8%5.2 days) at 25 °C. Also, the female longevity lasted 9.2%2.45 and 12.55%3.4 days at 30°C and 25 °C, respectively. At 30°C. female progeny was 58.5~1.88 progeny. while it was 44.89%1.32 at 25°C. In addition, the statistical analyses revealed that the parasitoid life cycle, female longevity and progeny rats were varied significantly according to the temperature regime used.
