摘要： 柠条种子害虫是影响柠条种子产量与质量的瓶颈性问题。为了掌握柠条种子害虫消长规律与柠条种子发育进程之间的内在关联,进而对害虫进行综合治理,并得出以下结果:(1)柠条种子发育受害虫影响严重。(2)平均每1000粒种子因虫害损失掉的重量是3.12g;害粒重约占种子总重量的13.23%;(3)3种种子害虫紧密的配合柠条有限的生长发育期,完成其自身生长发育,危害柠条种子。

Abstract: Seed pests have caused heavy losses to Caragana seed industry. In order to bring the Caraganaseed pest under control, the paper conducts a study on the inherent relation between the Population dynamicsand Ccaragana seed development stages. The main result found in the study include: (1) Caragana seeddevelopment was seriously effected by pests. (2)The loss of weight due to pests is 3.128 in per 1000 seeds, and Invaded seed weight account for 13.23%. (3)Three kinds of pests grow rapidly to mature by closely combining with Caragana's limited growth and development stages, and damaging Caragana seed.
