该文研究了光肩星天牛 Anoplophora glabripennis(Motsch.)世代分化现象 ,测定了卵期、幼虫和蛹期及全世代的发育起点温度和有效积温。结果表明 90 %左右个体为 1年 1代 ,1 0 %左右个体因卵孵化较迟 ,翌年有效积温仍未满足发育需要而形成 2年 1代。卵期、幼虫和蛹期及全世代发育起点温度分别为 1 1 .9± 1 .0 9℃、1 5 .2± 1 .87℃和 1 3.4± 0 .30℃ ,有效积温分别为 1 98.1± 1 5 .1 7日度、1 2 31 .89± 99.95日度和 1 2 6 4.2± 1 88.2 8日度
In this paper, the generational differentiation of Anoplophora glabripennis (Motsch.) Was studied, and the developmental onset temperature and effective accumulated temperature of egg stage, larval and pupal stage and whole generation were measured. The results showed that about 90% of individuals were 1 year and 1 generation, about 10% of individuals were hatched later due to the egg, the effective accumulated temperature in the following year still did not meet the development needs and formed 2 years and 1 generation. The starting temperature of eggs, larva, pupal and whole generation were 11.9 ± 1.09 ℃, 15.2 ± 1.87 ℃ and 13.4 ± 0.30 ℃, respectively, and the effective accumulated temperatures were 1 98.1 ± 1 5 .1 7 days, 1 2 31 .89 ± 99 95 days and 1 2 6 4.2 ± 1 88.2 8 days
