    3种内吸性杀虫剂对光肩星天牛幼虫的林间防治效果

    Field control efficiencies of three systemic insecticides on Anoplophora glabripennis larvae

    • 摘要: 为了筛选高效低毒杀虫药剂,防治光肩星天牛幼虫,本次试验选用的被害树种为馒头柳,采用树干输液法,选用氯虫苯甲酰胺、氟虫双酰胺和吡虫啉3种内吸性杀虫剂进行林间防治试验。3种杀虫剂的质量浓度分别设为:氯虫苯甲酰胺2、4、8 g/L,氟虫双酰胺0.6、1.2、2.4 g/L,吡虫啉2.8、5.6、11.2 g/L。结果发现,氯虫苯甲酰胺、氟虫双酰胺和吡虫啉对幼虫的防治效果分别为37.7%~54.5%、41.9%~66.0%和59.1%~86.4%。防治后,氯虫苯甲酰胺和氟虫双酰胺处理组的树干上无新产卵刻痕,吡虫啉处理组的树干上,有新产卵刻痕的株数占总株数的1/7,产卵刻痕密度为0.57个/株;对照组树干中,有新产卵刻痕的株数占总株数的50%~60%,产卵刻痕密度为2.0~2.2个/株。说明这3种杀虫剂对光肩星天成虫产卵行为具有不同程度的驱避作用。因此,这3种内吸性杀虫剂对光肩星天牛虫口密度的有效控制及降低其对林木的危害具有潜在价值。

       

      Abstract: In order to select efficient and low toxicity insecticides for controlling the Asian long-horn beetle (ALB), Anoplophora glabripennis larvae, Salix matsudana var. matsudana f. umbraculifera (SMM) was selected in this test since it was one of the damaged tree species by ALB. A series of toxicity tests with following three systemic insecticides were taken by SMM trunk infusion at three mass concentrations each: chlorantraniliprole (2, 4, 8 g/L), flubendiamide (0.6, 1.2, 2.4 g/L) and imidacloprid (2.8, 5.6, 11.2 g/L) against A. glabripennis larvae in the field. Our results showed that the overall control efficiencies of chlorantraniliprole, flubendiamide and imidacloprid on the larvae were 37.7%-54.5%, 41.9%-66.0% and 59.1%-86.4%, respectively. After prevention, there was no new oviposition pit on the trunks treated with chlorantraniliprole or flubendiamide, and there were new oviposition pits on one-seventh of the total trunks treated with imidacloprid, there were new oviposition pits on 50%-60% of the total trunks in the control group, and the oviposition pit densities were 2.0-2.2 pits per tree. The results showed that these three systematic insecticides had repellent effects on oviposition behavior of adults in different levels. Therefore, these systemic insecticides are potentially useful in effectively controlling ALB population densities and reducing their damages to forests.
