目的 测定黄胸散白蚁对密褐褶孔菌、黑木耳菌、茯苓菌和灵芝菌处理的马尾松木粉的偏好程度，为开发新的白蚁防治饵剂提供科学依据。方法 将不同木腐菌处理的和未处理的马尾松木粉放在用玻璃管连接的PVC圆筒中，供黄胸散白蚁自由选择，最后观测每种马尾松木粉引诱的白蚁数和被白蚁取食的量。结果 不同木腐菌腐朽的马尾松木粉对黄胸散白蚁的引诱力不同。其中，密褐褶孔菌处理的马尾松木粉引诱的白蚁数最多为（86.4±8.7）只，其他依次是黑木耳菌〔（48.8±1.9）只〕、茯苓菌〔（33.2±3.6）只〕和灵芝菌〔（21.8±3.9）只〕处理的马尾松木粉，这4种木腐菌处理的马尾松木粉引诱的白蚁数分别是未处理的8.8、5.0、3.4和2.2倍。但只有密褐褶孔菌、黑木耳菌和茯苓菌处理的马尾松木粉明显被黄胸散白蚁偏好，黄胸散白蚁对3种菌处理的马尾松木粉取食量分别是对照组的5.0、3.1和2.3倍。结论 黄胸散白蚁显著偏好密褐褶孔菌、黑木耳菌和茯苓菌处理的马尾松木粉，建议在今后研究和开发新的白蚁防治饵剂时，利用这些木腐菌处理基饵，以提高饵剂对黄胸散白蚁的防治效果。

Objective To determine the feeding preferences of the workers of Reticulitermes flaviceps for the Pinus massoniana wood flour treated with Auricularia auricularis (Gray), Gloeophyllum trabeum (Pers.), Ganoderma lucidum (Curtis), and Poria cocos (Schwein.) and to provide a scientific proof for developing new termite control bait. Methods The P. massoniana wood flour treated with different wood-rotting fungi and untreated wood flour were placed in PVC cylinders which were connected with glass pipes. The workers of R. flaviceps were allowed to visit different cylinders and feed on the wood flour ad libitum. The number of workers in each cylinder and the amount of wood flour consumed by them were determined. Results The P. massoniana wood flour treated with various wood-rotting fungi had different attractiveness to the workers of R. flaviceps. The wood flour treated with G. trabeum attracted the most workers (86.4±8.7), followed by that treated with A. auricularis (48.8±1.9), P. cocos (33.2±3.6), and G. lucidum (21.8±3.9); the numbers of workers attracted by the wood flour treated with these wood-rotting fungi were 8.8, 5.0, 3.4, and 2.2 times, respectively, as compared with those of workers attracted by untreated wood flour. However, among all treated wood flour, only that treated with G. trabeum, A. auricularis, and P. cocos were significantly preferred by the workers of R. flaviceps, and the consumptions of the wood flour treated with G. trabeum, A. auricularis, and P. cocos were 5.0, 3.1, and 2.3 times, respectively, as those of untreated wood flour. Conclusion The workers of R. flaviceps show significant preference for the P. massoniana wood flour treated with G. trabeum, A. auricularis, and P. cocos. It is recommended to use these wood-rotting fungi to treat bait material when developing new termite control bait in the future, so as to improve the control effect on R. flaviceps.
