【摘要】：通過野外調(diào)查和室內(nèi)選擇實(shí)驗(yàn),研究了朱紅毛斑蛾的食性。自然條件下,朱紅毛斑蛾為害榕屬植物中的小葉榕和垂葉榕,為害率分別為67.39%和47.61%。在T50時(shí),朱紅毛斑蛾對(duì)印度榕、對(duì)葉榕、無花果、黃葛樹、高山榕、小葉榕和垂葉榕的平均取食量分別為0、0、0、0、0、8.62±1.6 cm2和3.79±1.8 cm2;平均取食選擇指數(shù)分別為0、0、0、0、0、0.69和0.31,說明朱紅毛斑蛾僅為害小葉榕和垂葉榕,且對(duì)小葉榕有明顯偏好性。研究結(jié)果證明朱紅毛斑蛾為寡食性害蟲,提示在園林綠化過程中應(yīng)盡可能避免選擇易受害的單一樹種大面積栽種。
[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 鹵1.6 cm2 and 3.79 鹵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.
