【摘要】 为了明确华南地区星天牛主要寄主植物种类,本文筛选了21种有代表性的植物,对星天牛进行了室内、室外寄主选择试验。结果表明,星天牛在不同植物上的取食量和刻槽数量差异极显著,偏好在砂糖橘、苦楝、金桔和柠檬上取食,在砂糖橘、柠檬、金桔和小叶紫薇上刻槽产卵,取食对象和刻槽产卵对象不一致。研究证实,星天牛能在华南地区砂糖橘、玫瑰和柠檬三种植物上完成生活史,是星天牛的寄主植物。更多还原

【Abstract】 In order to identify the main host plant species of the Citrus Longhorned Beetle(CLB), Anoplophora chinensis in South China, 21 representative tree species were selected, and a complete host selection experiment indoor and outdoor was conducted. Results suggested, feeding amouont and number of grooves of CLB adults on different tree species showed highly significant difference, the CLB adults preferred feeding on Citrus reticulate, Melia azedarach, Fortunella margarita and Citrus limon, and preferred grooving on C. reticulate, followed by Rosa rugosa, F. margarita and Lagerstroemia indica. The choice of feeding is not consistent with that of grooving. The research verified that C. reticulate, R. rugose and C. limon were hosts of CLB, CLB can complete its life history in this three species in South China.更多还原
