| 摘 要： | 调查了莆田地区枇杷园梨小食心虫的生物学习性并进行了药剂防治试验，结果表明该虫在莆田地区一年发生6代，以老熟幼虫在枇杷树枝干的皮下或苗木嫁接口处结茧越冬，于5月上旬-中旬以幼虫为害果实最为严重。用Bt可湿性粉剂300倍液，90％晶体敌百虫1000倍液，2．5％敌杀死乳油2000倍液，50％杀螟松乳油1000倍液，20％杀灭菊酯乳油4000倍液都具有较好的杀虫效果，虫口减退率达85％-93％。并对梨小食心虫的综合治理提出建议。

| Abstract: | The bionomics of Grapholitha molesta Busck was observed in loquat trees in Putian area. It has 6 generations annually and overwinters as pupa under the shuck and seedling grafting interstices of the loquat tree branches. It damages the fruit seriously in early-mid May. The corrected mortality is 85%~93% with four kinds of pesticides, which have good control effect. This paper also provides feasible suggestions for integrated control of Grapholitha molesta Busck. |
