| 摘 要： | 在新疆棉花、加工番茄等特殊农田生态环境和种植模式下,螟黄赤眼蜂(Trichogramma chilonis)在田间自然扩散呈现随距离延长、寄生卵量递减的趋势,螟黄赤眼蜂在棉田、玉米田和加工番茄田扩散有效距离为8～10 m,最远扩散15 m,田间温湿度和风向等环境条件对螟黄赤眼蜂田间扩散和寄生影响作用明显,田间温度偏高和相对湿度偏低不利于螟黄赤眼蜂的寄生,下风口螟黄赤眼蜂寄生率明显高于上风口.

| Abstract: | Releasing experiments of parasite, Trichogramma chilonis, which was applied to control the Helicoverpa armigra and Ostrinia furnakalia (guenee)in particular field of Xinjiang were conducted in 2003～2004.The result indicated that the effective dispersal distance of Trichogramma chilonis in the cotton ,corn and tommato field of agricultural ecology in Xinjiang was about 8～10 metres,and the longest dispersal distance was 15meters. Dispersal distance had close relationship with temperature , moisture and wind speed etc. |

| Keywords: | Trichogramma chilonis dispersal characters in field parasitic rate |
