摘　　要：为有效、持续控制龙眼卷叶蛾,协调运用农业防治、生物防治、药剂防治等综合治理龙眼卷叶蛾类害虫的结果表明,综合治理区龙眼夏梢和秋梢幼叶的卷叶率分别为3.76%和2.34%,常规防治区的夏梢、秋梢卷叶率分别为5.49%和4.44%;综合治理区的夏梢期和秋梢期卷叶蛾幼虫被寄生蜂寄生率分别为22.58%和27.50%,而常规防治区的夏梢期和秋梢期幼虫寄生率仅分别为6.81%和8.47%,两者差异极显著。此外,综合治理区荔枝蝽卵粒寄生率、蒂蛀虫的蛹茧寄生率也远高于常规防治区。综合治理区不仅控制了卷叶蛾,且取得良好的生态效益。Integrated management of leaf rollers on longan was studied. The results showed that the rolled leaf rate in summer tip period and fall tip period in integrated management zone were 3.76% and 2.34%, respectively; The rolled leaf rate in control zone were 5.49% and 4.44%, respectively. The larval parasitic rate of leaf rollers in summer tip period and fall tip period in integrated management zone were 22.58% and 27.50%, respectively; But the larval parasitic rate in control zone were just 6.81% and 8.47%, respectively; The larval parasitic rate made a significant difference between integrated management zone and control zone. Furthermore, the parasitic rate of Ooencyrtus corbetti eggs and the parasitic rate of chrysalides of Conopomorpha sinensis in integrated management zone were far higher than in control zone. Not only leaf rollers were controlled, but the better ecological efficiency was gained.
