| 摘 要： | 2001—2003年6—8月对南岳景区松墨天牛成虫的取食、产卵、咬刻槽等习性进行了观察研究,结果表明,松墨天牛成虫除取食危害外,在健康松树上咬筑刻槽也会对寄主造成危害。在华山松枯立木、衰弱木和健康木上,无卵刻槽的比率分别为14.54%、44.09%和84.19%。大量的无卵刻槽导致健康松树树势衰弱,引起更多的同种成虫前来取食危害。因此,在健康松树上咬筑刻槽是松墨天牛成虫的另一种危害方式。

| Abstract: | Monochamus alternatus adults' habits of feeding,oviposition and biting nidi were observed in Nanyue Scenic Spot,Hunan Province between June and August of 2001,2002 and 2003.The results indicated that the adults caused damage not only by feeding but also by biting nidi in the healthy pines.The rate of nidi without eggs in dying pines,weakened pines and healthy pines was 14.54%,44.09% and 84.19% respectively.The large number of such nidi made the healthy pines weak and attracted more adults to nibble and damage.Therefore biting nidi in healthy pines was another way of damage caused by Monochamus alternatus adults. |
