麦蛾Sitotoga cerealella(Olivier)属仓库害虫。近年滨州市区及我场田间小麦罹受一代麦蛾幼虫为害。1987-1989年调查,成熟的小麦籽粒平均受害率为8.27％,受害严重的一穗32粒麦粒中7粒有虫。受害麦粒大部被虫蛀空,鉴于麦蛾田间防治的报道国内外尚未见及,为此,我们特进行了一代麦蛾幼虫田间防治最佳药物与适期试验研究。 Sitotoga cerealella (Olivier) is a warehouse pest. In recent years, Binzhou urban areas and my field wheat suffered the damage caused by the moth larvae. 1987-1989 survey, the average incidence of mature wheat grains was 8.27%, a serious damage to a grain of 32 grains of 7 insects. Most of the damaged kernels were moth-eaten. In view of the fact that there was no report about the control of the moth in the field at home and abroad, we conducted a special study on the optimal drug and periodical trials for the control of the moth larva in the field.
