| 摘 要： | 樟子松木蠹象主要危害樟子松枝和主干。在长春地区，1a发生一代，以成虫在枯枝落叶层下浅土层内和树皮裂缝内越冬。第2年4月下旬越冬成虫开始活动，5月中旬开始产卵，高峰期5月下旬；孵化高峰期为6月上旬；6月下旬化蛹，高峰期为7月上旬；7月上旬羽化，高峰期为7月中旬。卵期平均14d，幼虫期平均34d，蛹期平均12d，成虫期长达300～330d；幼虫分6个龄期。

| Abstract: | Pissodes sp. mainly attacked the branches and stem of Pinus sylvestris Var. Mongolica Litv. The pest, whose adult wintered in shallow horizon of soil and beneath forest litter or in the crack of bark, completed one generation in one year. The wintering adult changed to be active in the late of next April and began to lay eggs in middle May. The egging peak was in late May. The peak of hatching was in early June. Larvae began to pupate in late June and the pupation peak was in early July. Their eclosion began in early July and reached peak in middle July. The egg period, larvae period and pupa period were 14, 34 and 12 days respectively. The adult stage was 300 to 330 days. The larvae have six instars. |
