| 摘 要： | 针对贵州省木豆花实期钻蛀性害虫的为害情况，着重调查分析了木豆钻蛀性害虫的种类、为害特征和为害程度。结果表明：木豆花实期的钻蛀性害虫包括豆荚野螟、棉铃虫、钝黑潜蝇和豆黑潜蝇。本调查中，平均株受害率达59％，其中最高88％，最低40％；平均荚受害率达44．5％，其中最高68％，最低35．8％。宿根木豆钻蛀性害虫发生为害较重，新植木豆受害相对较轻；坡地或缓坡木豆受害相对较轻，平地或台地相对较重。本文还分析了木豆钻蛀性害虫严重发生的原因，并提出了防治措施。

| Abstract: | In view of damages caused by borers against pigeon pea in the blooming and pod-bearing period in Guizhou, the species, damage characteristics and damage extent of these pests were surveyed. The results indicated that the borers included Marnca testulalis （Geyer） , Heliothis armiger （Hubner） , Metanagromyza obtuse Malloeth and Metanagromyza chalosoma Spendeet. In this investigation, average damage percentage was 59%, the high damage percentage reached 88% and the low one was 40% ; average damage percentage of pod was 44.5% , their peak reached 68% and the low one was 35.8%. The ratoon was damaged more seriously than newly planted pigeon pea while pigeon pea was damaged less seriously on the slope than that on the fiat land. Accordingly the causes were analyzed and the measures of control were proposed. |
