在福建武夷山采用林间调查和诱捕松墨天牛成虫的方法,研究不同健康类型马尾松林分松墨天牛种群动态。结果表明:健康林分(A)、亚健康林分(B)、不健康林分Ⅰ(C)和不健康林分Ⅱ(D)4个监测点诱捕到的松墨天牛数量分别为73、108、136、162头;危害程度分别为:轻度危害、中度危害、中偏重度危害、重度危害。松墨天牛在武夷山市1 a发生1代,不同健康类型马尾松林分中松墨天牛成虫均于5月上旬始见,但其终见期不同,不健康林分Ⅰ和健康林分中松墨天牛成虫终见于9月中旬,而其他类型林分终见期在9月下旬;亚健康林分、不健康林分Ⅰ中松墨天牛活动高峰期完全一样,但不同于健康林分、不健康林分Ⅱ。
In Wuyishan, Fujian Province, the population dynamics of Pinus massoniana in different types of Pinus massoniana forest was studied by means of forest investigation and trapping adult Monochamus alternatus. The results showed that the number of Monochamus alternatus trap trapped in 4 monitoring sites of healthy forest (A), sub-healthy forest (B), unhealthy forest Ⅰ (C) and unhealthy forest Ⅱ (D) were 73,108 , 136,162 head; the degree of harm is respectively: mild hazard, moderate hazard, moderately severe hazard, severe hazard. Monochamus alternatus occurred in the first generation in Wuyishan City. The adults of Monochamus alternatus in different types of health were all seen in the first ten days of May, but the final dates were different. The unhealthy stands Ⅰ and the Songzhong days in the healthy stands Adults of the cattle eventually see mid-September, while the other types of forest end-date in late September; sub-healthy forest, unhealthy forest Ⅰ Monochamus alternatus activity peak is exactly the same, but different from the healthy forest, unhealthy forest II.
