三亚瓜类作物上实蝇优势种类鉴别及不同诱捕处理的效果

Studies on identification of dominant species of fruit flies on cucubit plants and effects of different trapping treatments in Sanya

实蝇是园艺作物上的重大害虫,长期使用化学防治已产生抗药性,为减缓实蝇的抗药性产生速度而开展了实蝇类害虫绿色防控技术研究。通过对甜瓜及苦瓜上的实蝇种类进行调查,并比较了4种不同诱捕方法对瓜实蝇、橘小实蝇的诱捕效果。结果表明,甜瓜大棚内的实蝇优势种群为瓜实蝇(Bactrocera cucurbitae Coqillett),露地苦瓜的实蝇优势种群为橘小实蝇(Bactrocera dorsalis Hende);4种不同诱捕处理对瓜实蝇、橘小实蝇的诱捕效果差异显著,其中黄色粘虫板+瓜果实蝇诱粘剂的诱捕处理诱捕的瓜实蝇、橘小实蝇数量最多,诱捕效果最好,建议生产上可结合使用悬挂黄色粘虫板+瓜果实蝇诱粘剂的诱捕方法防治瓜实蝇、橘小实蝇。

Fruit fly is a major pest on horticultural crops,the long time using of chemical insecticides results in resistance.In order to slow down the production rate of resistance,this study carried out green control technology on fruit flies.In this study,the species of fruit flies on melon and balsam pear were investigated,and the trapping effects of four different trapping methods on Bactrocera cucurbitae and Bactrocera dorsalis were compared.The results showed that the dominant population of fruit flies in greenhouse muskmelon was B.cucurbitae,and the dominant population of fruit flies in balsam pear field was B.dorsalis.The trapping effects of four different trapping treatments on the two species of fruit flies were significantly different,the trapping effect were best by the way using yellow sticky insect board and fruit fly attractant.It was suggested that yellow sticky insect board and fruit fly attractant could be used to control B.cucurbitae and B.dorsalis.
