| 在室外大型密闭网棚内以苦楝（Melia azedarach）、砂糖橘（Citrus reticulata）、桑树（Morus alba）、木麻黄（Casuarina equisetifolia）、柳树（Salix sp.）和金橘（Fortunella margarita）6个寄主植物的3 a生盆栽苗饲喂星天牛（Anoplophora chinensis）成虫，对其补充营养行为进行观测。结果表明：在供试植物中，星天牛喜食砂糖橘、苦楝和金橘，不同性别星天牛成虫在寄主选择上没有显著差异；在观察时间段内，8:00—12:00时和16:00—18:00时是补充营养较为集中的时段；单次补充营养时间在木麻黄上历时最长，达35.7 min，其次是苦楝和砂糖橘，历时分别达30.3和26.3 min，在桑树上补充营养时间最短，仅9 min；不同性别星天牛单次补充营养时间在砂糖橘和苦楝上无显著差异。 |

| Abstract: |
| The adults of Anoplophora chinensis were raised with 3 years old potted seedlings of Melia azedarach, Citrus reticulata, Morus alba, Casuarina equisetifolia, Salix sp. and Fortunella margarita in three large net rooms, and their complementary nutrition behaviors were observed. The results showed that the adults were fond of feeding Citrus reticulata, Melia azedarach and F. margarita. There was no significant difference in the host selection between female and male. In the observation period, 8:00—12:00 am and 16:00—18:00 pm were the adult concentrated period of complementary nutrition. The average time of adult complementary nutrition fed on Casuarina equisetifolia lasted 35.7 min, followed by Melia azedarach and Citrus reticulata which lasted 30.3 and 26.3 min, respectively. And the shortest time of adult complementary nutrition fed on Morus alba lasted 9 min. There was also no significant difference between the average time of complementary nutrition of female and male fed on Melia azedarach and Citrus reticulata. |
