通过观察 5个不同恒温条件 (15℃± 1.0℃ ,2 0℃± 1.0℃ ,2 5℃± 1.0℃ ,30℃± 1.0℃ ,35℃± 1.0℃ )下桨角蚜小蜂生长发育情况 ,确定各个虫态的发育历期 ,计算桨角蚜小蜂各虫态的发育起点温度和有效积温。结果表明 ,卵、幼虫、蛹、全世代的发育起点温度和有效积温分别为11.5℃和 4 0 .4日度、 10 .3℃和 86 .9日度、 7.0℃和 78.8日度、 9.5℃和 2 30 .5日度 ,并建立历期预测式 ,得出理论上桨角蚜小蜂一年发生 6 .9代 ,与田间实际发生代数相吻合。
By observing the growth and development of wasps in five different isothermal conditions (15 ℃ ± 1.0 ℃, 20 ℃ ± 1.0 ℃, 25 ℃ ± 1.0 ℃, 30 ℃ ± 1.0 ℃, 35 ℃ ± 1.0 ℃) Determine the developmental stages of the various insect states, calculating the developmental starting point temperature and effective accumulated temperature of the larvae of the insect. The results showed that the onset and effective accumulated temperatures of eggs, larvae, pupae and whole generation were 11.5 ℃ and 4.0 days respectively, 10.3 ℃ and 86.9 days, 7.0 ℃ and 78.8 days, 9.5 ℃ And 2 30.5 days, and the establishment of a predictive period, the theoretical conclusion was that the bee pollinator was 6.9 generations a year, coinciding with the actual occurrence of algebra in the field.
