| 摘 要： | 粟杆蝇幼虫为害谷子常造成枯心或不实。此虫一年发生二代,部分一代。以老熟幼虫在5—10厘米土层中越冬。成虫于6月中旬出現,6月末达盛期,每雌产11—41卵,产卵于粟杆的基部。粟杆蝇的发生为害与湿度有密切关系,交尾、产卵、幼虫孵化、以及侵入粟茎均需高湿。田間枯心率与当年6月份降雨量的相关系数为0.71(P<0.01),相关显著。在晚播、高肥、密植的条件下,枯心发生严重。谷子品种、生育速度均与被害程度有关。在粟田雌蝇出現高峯期噴5％DDT与0.5％666等量混合粉剂,有良好的防治效果。

| Abstract: | The millet stem fly, Atherigona biseta Karl, is an important pest of millet (Setaria italica Beauv.) in Liaoning, Chilin and the northern-part of Hopei. The larvae infested the young central shoots inside the stem. The loss amounted to 10-20% of the crop in usual conditions and 40-80% in epidemic years. In addition to the millet, S. viridis (L.) Beauv., S. Faberii Herrm, and S. glauca Beauv. were found to be its wild hosts. There were two generations a year. The mature larvae of the second generation hiberhated in the soil at a depth of 5-10 cm. Pupation took place at the end of May. The flight peak of the first generation appeared in late June. The female laid 11-41 eggs in her whole life. In most cases, only a single egg was laid in one stem at the lower part just above the ground. Higher relative humidity seemed to be favorable to this pest in all stages. The degree of infestation of millet was shown to be highly correlated with the precipitation in June. (r=0.71). The damage was usually more severe for late sown or densely planted crops, or when the field was over fertilized with nitrogen. The varietal differences in resistance to this borer were found to be significant. Those cultural practices which promoted quicker growth of the seedlings might greatly reduce the infestation. At the peak of the adult statge dusting with 5% DDT mixed with an equal amount of 0.5% BHC gave satisfactory control. |
