不同杀蚁饵剂防治红火蚁在贵州初探

A Study on the Effect of Different Proportions of Pesticides on Control of Fire Ants in Guizhou

2018年8至9月,在贵州兴义,选用0.05%茚虫威杀蚁饵剂25 g/巢、0.1%茚虫威杀蚁饵剂20 g/巢、1%氟蚁腙杀蚁饵剂20 g/巢、0.73%氟蚁腙杀蚁饵剂20 g/巢防治红火蚁。结果表明,4个处理防治红火蚁工蚁和蚁巢,施药14 d后都表现较好的防效,防效大于80%,有较好的速效性和持效性。药后42 d平均防效大于90%,建议在红火蚁防治工作中选择使用。

Four insecticidal baits,0.05%ninhydrin 25 g,0.1%ninhydrin 20 g,1%fluorohydrazone 20 g and 0.73%fluorohydrazone 20 g per nest were tested to control red fire ants in Xingyi,Guizhou province,from August to September in 2018.The results showed that the control effectiveness of all tested baits were over than 80%at 14 d after application,which suggested these baits had good quick and sustained effectiveness against the red fire ant.The averaged control effectiveness was above 90%at 42 d after application.This suggested that the four baits were good to control of red fire ants.
