朱红毛斑蛾嗜食性的研究
发布时间：2019-05-13 21:16
【摘要】：通过野外调查和室内选择实验,研究了朱红毛斑蛾的食性。自然条件下,朱红毛斑蛾为害榕属植物中的小叶榕和垂叶榕,为害率分别为67.39%和47.61%。在T50时,朱红毛斑蛾对印度榕、对叶榕、无花果、黄葛树、高山榕、小叶榕和垂叶榕的平均取食量分别为0、0、0、0、0、8.62±1.6 cm2和3.79±1.8 cm2;平均取食选择指数分别为0、0、0、0、0、0.69和0.31,说明朱红毛斑蛾仅为害小叶榕和垂叶榕,且对小叶榕有明显偏好性。研究结果证明朱红毛斑蛾为寡食性害虫,提示在园林绿化过程中应尽可能避免选择易受害的单一树种大面积栽种。
[Abstract]:The feeding habits of Phyllostachys pubescens were studied by field investigation and indoor selection experiment. Under natural conditions, the damage rates of Ficus microphylla and Ficus verticalis were 67.39% and 47.61%, respectively. At T50, the average feed intake to Ficus India, Ficus figs, Ficus koraiensis, Ficus Alba, Ficus microphylla and Ficus verticola were 0.000,0, 8.62 卤1.6 cm2 and 3.79 卤1.8 cm2;, respectively. The average index of feeding selection was 0, 0, 0, 0, 0, 0 and 0.31, respectively, which indicated that only Ficus microphylla and Ficus verticalis were damaged, and had obvious preference for Ficus microphylla. The results showed that Phyllostachys pubescens was an oligovorous pest, suggesting that the selection of vulnerable single tree species should be avoided as much as possible in the process of landscaping.
