摘要
采用林间调查和挂设APF-I型松墨天牛化学引诱剂诱捕松墨天牛的方法,研究不同健康类型林分松墨天牛种群动态。结果表明:松墨天牛在将乐1 a发生1代,各监测点松墨天牛成虫均始见于5月上旬,不健康林分和健康林分中松墨天牛成虫终见于每年9月中旬。不同健康类型的A、B、C 3个监测点诱捕到的松墨天牛成虫数量分别为71头、112头和136头。松墨天牛在健康林分、亚健康林分、不健康林分中的危害程度分别为轻度危害、中度危害和重度危害。亚健康林分、不健康林分中松墨天牛活动高峰期完全一样。各不同健康类型林分次高峰期和一般活动期松墨天牛成虫诱捕量差异不显著;在各个时期各林分中松墨天牛雌成虫百分比差异不显著。
Using the method of forest investigation and hanging traps with APF-I Monochamus alternatus attractant trapped alternatus were studied on the population dynamics of Monochamus alternatus on different types of health Masson pine stands. The results showed that： Monochamus alternatus in Jiangle have one generation in a year, Monochamus alternatus in each monitoring point were beginning in early May, on health stand and unhealthy stand the adults end in mid September. The amounts of the trapped Monochamus alternatus of A, B, C monitoring point in different types of health Masson pine stands were 71, 112 and 136, respectively. The harm degree of Monochamus alternatus in health stand, subhealth stand and unhealthy stand were mild harm, moderate harm and severe harm, respectively. The emergence peak of Monochamus alternatus in subhealth stand and unhealthy stand was exactly. Different types of health Masson pine stands peak and the general activity of Monochamus alternatus trapping were not significant; in each stand in different periods of Monochamus alternatus adult female percentage had no significant differences.
