摘　　要：皮氏叶螨对香蕉的危害日趋严重,已经成为海南香蕉产业发展的重要限制因子。本试验测试了6%克螨净乳油、5%阿维·氯氰乳油、40%速灭抗乳油、20%高渗辛硫磷乳油对皮氏叶螨的防治效果。试验结果表明,克螨净对香蕉皮氏叶螨防效最好,以2000～4000倍喷雾施药后7d防效均达85%以上;阿维·氯氰、速灭抗的防效次之,而辛硫磷对叶螨卵的防效最差,导致药后叶螨很快上升。Tetranychuspiercei McGregor gradually endangered the banana seriously, having become an important restrict factor of development of banana industry in Hainan province. This field trial have tested the prevention and cure efficacy of several acaricides （6% pyridaben EC, 5% abamectin-cypermethrin EC, 40% profenofos EC, 20% phoxim EC） against the Tetranychus piercei McGregor. The result showed that the prevention and cure efficacy ofpyidaben is best, after 7 days all efficacy are over 85% at the dosage 2 000～4 000 times dilution, the abamectin-cypermethrin and profenofos are better, and phoxim is the lowest against eggs of Tetranychus piercei, therefore, Tetranychus piercei will go up after control.
