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
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.关键词
