落叶松种子小蜂为落叶松种子的重要害虫,该虫1 a发生1代,以老熟幼虫在种子内越冬,翌年5月中下旬化蛹,6月上中旬成虫羽化,6月下旬在球果上产卵,7月上中旬在种子内可见到幼虫。基于此,对落叶松种子小蜂生物学特性、检疫检验和除害方法进行阐述,供读者参考。 The larch seed wasps are the important pests of larch seeds. The larvae 1 a occur for one generation, the mature larvae winter in the seeds, and pupae are formed in the middle and late May of the following year. The adult pests emerge in the middle of June, Fruit spawning, in mid-July in the seeds can be seen larvae. Based on this, the biological characteristics of larch seed wasps, quarantine inspection and pest elimination methods are described for readers’ reference.
