荔枝拟木蠹蛾(Arbela dea Swinhoe)是荔枝、龙眼等热带、亚热带果树及林木的常见害虫,其幼虫蛀茎或枝条成坑道,夜出啃食树的韧皮部为害。1988—1989年,作者应用苹果蠹蛾线虫(Steinernema carpocapsae A24)1—8×10~3条/ml水悬浮液,注射进荔枝拟木蠹蛾的坑道或喷雾至隧道,防治面积1500亩(100ha),防效达89%—100%,有效地压低了荔枝拟木蠹蛾在这地区的为害,是一种经济的、有效的生物防治手段。 Arbela dea Swinhoe is a common pest of tropical and subtropical fruit trees and forest trees such as litchi and longan. Its larvae are ditching stems or branches into tunnels and are damaged by the phloem of gnawing trees at night. From 1988 to 1989, the authors applied a water suspension of 1-8 × 10-3 / ml of Steinernema carpocapsae A24 into the tunnels or sprayed into the tunnels of the litchi shoots, controlling 1500 acres (100 ha ), Effective control of 89% -100%, effectively depriving the licorice Lydia in the area of ​​damage, is an economical and effective means of biological control.
