In: Egyptian journal of biological pest control 2005.v.15(1,2)Summary: The influence of tour constant temperatures (15, 20, 26 and 30°C) on some biological aspects of the egg parasitoid, Trichugramma evanescens West. on 12:12 LD, and 65±5% R.H. was studied. Thermal developmental requirements and threshold of development for the parasitoid and the two laboratory hosts; Angoumois grain moth, Silolroga cerea/ella Oliv. and Mediterranean flour moth, Anagasle (Ephestia) kuehniella Zell. were estimated. Differences between parasitism rates by T. evanescens on S. cerealella or A. kuehniella were insignificant (96.4 and 93.9%, respectively).
