摘要
为防治土栖白蚁危害桉树幼林 ,选择 4种药剂进行桉树容器苗浸根后上山造林试验和白蚁致死驱避试验。结果表明 :容器苗经 4种药剂浸根后造林 ,以绿僵菌复合剂的防治效果最好 ,幼林白蚁危害致死率仅 3.4 % ;施用萘丸的防治效果最差 ,幼林白蚁危害致死率达 2 0 .5 % ,专项驱避试验对白蚁的驱避作用也不明显。
Eucalyptus container seedlings were dipped with 4 pesticides before forestation in order to control termite and increased forestation survival rate. The toxic and repellent test of pesticides to termite are also conducted. The result shows that use the Metarhizium compound preparations dip seedlings can effectively prevent the termite, the death rate of the young plantations caused by termite are only 3.4%. Naphthalene have the worst control effect, the death rate of young plantations caused by termite are 20.5%. The repellent test result also shows that the repellent effect for termite are not effective. The cost of the pesticides are also analyzed in the paper.
