| 摘 要： | 研究了莆田地区枇杷园梨小食心虫的生物学特性并进行了药剂防治试验 ,实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 30 0倍液 ,2 .5 %敌杀死乳油 2 0 0 0倍液 ,90 %晶体敌百虫 10 0 0倍液 ,2 0 %杀灭菊酯乳油 4 0 0 0倍液 ,5 0 %杀螟松乳油 l0 0 0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可行性建议。

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