用好年冬和金点子两种药剂对梨树梨大绿蚜防治效果为:施药1d、3d、5d、7d、9d、14d后,好年冬防效分别达77.20%、87.54%、87.21%、90.09%、84.50%、85.27%,金点子防效为69.39%、72.93%、49.16%、80.04%、61.52%、56.20%。药后对两种药效进行差异性比较,药后1d差异显著,药后7d差异极显著,从整个观察周期来看,1-14d两种药的防治效果差异极显著。由于蚜虫的大量死亡,梨树节肢动物的多样性指数增加,好年冬对群落的干扰较大。

The results showed that the control effect of A. niloticus and P. arborescens on the green apple aphids was 77.20%, 87.54% and 87.21 respectively after 1 d, 3d, 5d, 7d, 9d and 14d %, 90.09%, 84.50% and 85.27% respectively. The antimicrobial effect of the golden seeds was 69.39%, 72.93%, 49.16%, 80.04%, 61.52% and 56.20% respectively. The differences of the two pharmacodynamics were compared after treatment. The difference was significant on the 1st day after treatment, and the difference was very significant on the 7th day after treatment. From the observation period, there was significant difference in the control effect between the two drugs. Due to the large number of deaths of aphids, the diversity index of pear-tree arthropods increased, so that the winter was more disturbing to the community.
