摘要
本文明确了从埃及引进的广赤眼蜂在35℃条件下只有3．33％～4．32％的个体能够正常羽化出蜂；在15℃～32℃的温区内发育历期、成蜂寿命、随温度的升高而缩短；相对湿度对广赤眼蜂的羽化出蜂具有明显的影响，相对湿度在45％以上时羽化出蜂率均在80％以上，在33％～45％之间羽化出蜂率可达50％左右，产卵雌蜂比率达90％，单雌平均产卵量在34．67以上，在23％时羽化出蜂率只有27．14％。
The biological characteristic of Trichogramma evanescens from Egypt was studied . It indicated that emergence rate of T. evanescens was only 3.33%- 4. 32% normally under the condition of 35 ℃. Within a temperature range of 15 ℃-32℃, developmental phase and adult life--span shortened with rising of temperature. The relative humidity affected obviously emergence of T. evanescens. Emergence rate was more than 80 % over the relative humidity of 45%. Within the relative humidity of 33%-45%, emergence rate was approximately 50%, females that laid eggs accounted for 90%, and a female laid over 34. 67eggs. Under the condition of 23%, emergence rate was only 27.14%.
