摘要
应用虫线清、敌杀死、氧乐果、保绿宁和吡虫啉等5种农药注射防治萧氏松茎象幼虫,结果表明:对于老熟幼虫,吡虫啉和保绿宁效果较好,均达到了50%,对于第2代幼虫,保绿宁效果最好,虫线清、敌杀死和吡虫啉次之,都在80%以上。对第2代幼虫的药效明显高于老熟幼虫。综合以上结果,保绿宁和吡虫啉是具有推广应用前景的药剂。5种农药对不同林龄湿地松的萧氏松茎象幼虫效果差异不明显。
Field trials of tunnel injection against larvae of Hylobitelus xiaoi were conducted with chongxianqing, decis, omethoate, baoluning and imidacloprid EC. The results showed that the control effect of baoluning and imidacloprid EC reached 50% respectively 5 days after the injection against the mature larvae. The efficacies of baoluning, chongxianqing, decis and imidacloprid reached 80% against the new larvae. So baoluning and imidacloprid were the better pesticides to apply in control of H. xiaoi.
