连续4a的田间系统调查及试验结果表明,绣线菊蚜在豫西地区苹果园每年可发生15~18代,以受精卵在小枝条芽腋、枝叉等处越冬。其种群数量消长在1a内有春、秋两个为害高峰。春季高峰期危害重,应积极防治;秋季蚜虫危害后,有间接抑制新梢生长、促进花芽形成的作用,可不作为防治的重点对象。不同品种、不同树龄上的种群数量消长动态也有一定差异
The systematic field investigation and experimental results of consecutive 4 years showed that the Spiraea Aphidia can occur 15-18 generations per year in the apple orchard of western Henan Province, with the fertilized eggs overwintering at axillary branches and shoots of twigs. The population growth and decline in the 1a spring and autumn two peak. In the peak of spring, it is very harmful and should be actively controlled. After the fall of aphids, it may indirectly inhibit the growth of new shoots and promote the formation of flower buds, which may not be the focus of prevention and treatment. Different species, different age groups on the dynamics of population growth there are some differences
