【摘要】 报道了黄山风景区松墨天牛、褐幽天牛和短角幽天牛3种主要松蛀虫成虫携带拟松材线虫等非病原线虫的情况。监测显示3种松蛀虫均能携带线虫,以松墨天牛携带机率最高,达61 3%。褐幽天牛和松墨天牛平均携带线虫数量较多,分别为5128 6、3622 0条·头-1。温泉的松墨天牛和西海的褐幽天牛携带的线虫数量最高,分别达4781、10840条·头-1。本文还报道了不同时间诱捕的松墨天牛和褐幽天牛性别、个体大小与携带线虫数量的关系。更多还原

【Abstract】 Non-pathogenic nematodes, such as Bursaphelenchus mucronatus , carried by major pine borer beetles, Monochamus alternatus , Spondylis buprestoides and Arhopalus rusticus in Huangshan Scenic Area were investigated in 2000-2001. Results showed that all the three pine beetles were competent to carry nematode,61.3% of M. alternatus found caring nematode.The largest average number of nematode carried per beetle were found in A. rusticus and M. alternatus , with the number of 5 128.6 and 3 622.0 and in Wenquan scenic spot and Xihai scenic spot, with average number of 4 781 and 10 840 for M. alternatus and A. rusticus respectively. Time dynamic of the nematode carried by beetles and the relationships between genital, body size and the number of nematode carried were also discussed.更多还原
