摘要
玳玳是芸香科柑桔属的一种香料,大面积种植屡遭桔潜蛾严重为害。桔潜蛾在玳玳上1年发生11个世代,发生在秋梢期的第七至九代为主害代。秋梢受害率达52.1—100%,经济损失达24.9%以上。根据害虫和寄主各自生物学特性,采用以改变害虫生态条件为主,协调运用科学管梢、以肥调梢、保护利用天敌和药剂挑治等四项综防措施。经2600亩应用,梢叶产量提高65.4%,冠幅平均扩大34%,保梢效果达91%,三年企业直接获利10万余元。
As Citrus aurantium var.amara Engl,a valuable perfume plant ofCitrus genus,is grown in a large area in Jianyang County,Fujian Prov-ince,it always suffers the damage of citrus leaf-miner Phyllocnistiscitrella Stainton.It was found that there are eleven generations a year ofthis insect on C.aurantium var.amara,and its 7-9th generations occur-red in autum shoot period are most dangerous.As the damage rate ofautum shoots ranged from 52.1% to 100%,24.9% or more of the bene-fit of this perfume plant was lost.According to the biological charac-ters of this insect pest and its host,a series of control measures,in-cluding to change the ecological condition of this insect as the main
step,and the integrated use of proper shoot management,protection andutilization of natural enemies,and selective chemical control were exe-cuted in a 2,600 mu area,the shoot leaf yield was 65.4% enhanced,andthe mean diagram of tree canopy was 34% enlarged,the efficacy ofshoot protection was up to 91%,and the direct benefit of enterprise in
three years was more than one hundred thousands yuan.
