中文摘要: |
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。 |
英文摘要: |
Feeding preferences of Phauda flammanswere studied through field investigation and choice experiment in laboratory. Result showed thatP. flammans larvae only damaged the F. concinna and F. benjamina among Ficus plants tested in this study. Damaged rates of F. concinnaand F. benjamina were 67.39% and 47.61% in the field. Results from the choice experiment indicated that average feeding amount ofP. flammans larvae on F. elastica, F. hispida, F. carica, F. virens, F. altissima, F. concinna and F. benjamina were 0, 0, 0, 0, 0, 8.62±1.6 cm2 and 3.79±1.8 cm2 at T50, and the average preference index were 0, 0, 0, 0, 0, 0.69 and 0.31, respectively. Results displayed thatP. flammans larvae preferred F. concinna. In conclusion, our data illustrated P. flammans is an oligophagous pest, and suggested that vulnerable trees could not plant in a large scale for landscaping. |
