| 为了筛选出对薰衣草 Lavandula angustifolia 田中柳尖胸沫蝉 Aphrophora costalis 防治效果较好
且低毒低残留的药剂，于 2020 年 5 月—6 月在伊犁州霍城县芦草沟镇四宫村进行柳尖胸沫蝉药剂筛选试
验。选取 20% 啶虫脒可溶液剂 20 000 倍液、12% 阿维 ? 噻虫嗪微囊悬浮剂 1 000 倍液、3.6% 烟碱 ? 苦参
碱微囊悬浮剂 2 000 倍液、18% 阿维菌素微乳剂 1 250 倍液、16 000TU/mg 苏云金杆菌可湿性粉剂 300 倍
液，采用喷雾法将 5 种药剂均匀的喷洒至薰衣草田内，并于薰衣草收花期采集不同药剂处理的薰衣草花
穗进行农残检测。从死亡率来看，苏云金杆菌和阿维 ? 噻虫嗪对柳尖胸沫蝉的防治效果最好，其死亡率
分别达到 33% 和 32%；从虫口减退率来看，苏云金杆菌和烟碱 ? 苦参碱的效果较好，虫口减退率分别为
74.4% 和 76.7%；从施药后 1 个月的防效来看，处理区与对照区差异不显著；从农残检测结果可见：除啶
虫脒外其他药剂均未检测出农药残留。防治时期的选择直接影响柳尖胸沫蝉的防治效果。 |

| Abstract: |
| In order to screen out the insecticides with good control effect and low toxicity and low residue
on the Cicadas in the lavender field, the screening test of the Cicadas in the lavender field was conducted in
Scigong Village, Lucaogou Town, Huocheng County, Yili Prefecture, from May to June 2020. Two thousand
times of 20% acetamidine solution, one thousand times of 12% Avi ? thiamethoxam microcapsule suspension, two
thousand times of 3.6% Nicotinic-matrine microcapsule suspension, one thousand, two hundred and ?fty times
of 18% avermectin microemulsion, and three hundred times of 16 000TU/ mg Btwettable powder were selected.
Five kinds of agents were sprayed evenly into the lavender ?eld by spray method, and the ?ower ears of lavender
treated with different agents were collected at the ?owering stage for agroresidue detection. From the perspective
of mortality, Bt and Avi ? thiamethoxam had the best control effect on the nympha, the mortality rate was 33% and
32%, respectively. From the perspective of the rate of pest decline, the effect of Bt was better, and the rate of pest
decline was 74.4% and 76.7%, respectively. There was no signi?cant difference in the control effect between the
treatment area and the control area at 1 month after application. The results of pesticide residue detection showed
that no pesticide residues were detected except acetamidine. The selection of control period directly affects the
control effect of the Cicadas. |
