落叶松红腹叶蜂生物学特性及防治技术研究

Study on Biological Characteristics and Control of Pristiphora Erichsoni Hartig

落叶松红腹叶蜂属膜翅目、叶蜂科 ,在山西省 1年 1代 ,老熟幼虫下树在枯枝落叶层下结茧越冬 ,5月底开始化蛹 ,6月上旬羽化开始并产卵。采用化学、生物等综合性措施可控制其发生蔓延。

Pristiphora Erichsoni Hartig is of hymenoptera order, sawfly family. It occurs in Shanxi Province one generation within a year and they are living through winter by matured larva in cocoon under the deadwood defoliation in forest. Pupation starts at the end of May and eclosion and lay-eggs in early June. It is suggested that chemical and biological integrated control methods can be adopted to prevent the spread.
