稻螟赤眼蜂

采用卵卡浸渍法测定药剂对稻螟赤眼蜂成蜂影响的结果表明，吡虫啉、三唑磷、氟虫腈、毒死蜱能显著影响F0代成蜂存活、寄生及F1代成蜂羽化。

The results of host egg exposure showed that imidacloprid , triazophos , fipronil and chlorpyrifos were all badly detrimental to adult survival , parasitism capacity ( F0 ) and adult emergence ( F1 ) .

三化螟和二化螟发生均较重的安徽省和县稻螟赤眼蜂寄生率为171%，每一卵块羽化的蜂仅35头。

And in western Jintan only 17.1 % eggs was parasitized and 3.5 wasps emerged per egg mass .

结果还表明盖毛在卵块上的完整性对稻螟赤眼蜂的寄主搜索行为有明显影响。

However , the results also suggest that damage to the egg fur could affect host selection and recognition behavior of the wasp .

结论如下：1、开展了稻田释放稻螟赤眼蜂防治水稻稻纵卷叶螟和二化螟的工作。
