黄山市松墨天牛及小灰长角天牛羽化规律研究

Study on the Eclosion Regularities of Monochamus alternatus and Acanthocinus griseus in Huangshan City

松墨天牛及小灰长角天牛是松材线虫的传播媒介,本文研究这两种天牛的羽化规律,旨在为有效防治这两种天牛提供理论依据。研究表明,松墨天牛羽化时段为4月下旬至7月上旬,羽化高峰期集中在5月下旬至6月上旬,雌雄松墨天牛羽化规律无明显差异;小灰长角天牛羽化时段为4月下旬至7月中旬,羽化高峰时段集中在5月中上旬,7月上旬出现一次小的羽化高峰,雌雄小灰长角天牛羽化规律无明显差异。

Monochamus alternatus and Acanthocinus griseus are both key vectors of pinewood nematode.In this paper,a study was made on the eclosion regularities of the two species so as to provide theoretical basis for effective control of the two species.The study results showed that the eclosion period of Monochamus alternatus was from late April to early July and its peak eclosion period was from late May to early June with no significant differences between the male and female.The eclosion period of Acanthocinus griseus is from late April to mid July,and its peak eclosion period is in early and mid May and early July with no significant differences between the male and female.
