| 摘 要： | 组建了美洲斑潜蝇自然种群生命表,在此基础上应用排除控制指数分析方法,分析了寄生性天敌对美洲斑潜蝇自然种群的控制作用。结果表明,美洲斑潜蝇在秋季花前期菜豆上种群趋势指数为５．６１;寄生性天敌的寄生是影响美洲斑潜蝇自然种群数量增长的重要因子;若排除寄生性天敌的作用,其种群密度将增长为原来的２．４７６倍。

| Abstract: | The life table of the natural population of the vegetable leafminer, Liriomyza sativae Blanchard was constructed based on the data of systemic survey on the untreated plot of bean, Phaselus vulgaris . The suppression effect of parasites on the natural population of the leafminer was analyzed by means of exclusive index of population control (EIPC). The results indicated that the trend index of population dynamics of the leafminer (I value) was 5.61. The factor of "parasites" was the important facto... |
