桔小实蝇取食习性的利用研究

Feeding behavior of Bactrocera dorsalis(Hendel)

摘要: 从诱杀方式、诱杀剂的水分和甜度等方面探讨了食物诱杀剂对桔小实蝇的防治效果,并在田间进行小范围的防效对比试验。结果表明:采用芒果果浆法能诱集到大量的桔小实蝇成虫;每天更换新鲜的芒果果浆能显著提高诱杀效果;在芒果果浆中添加红糖10gL-1、蜂蜜10mLL-1和麦芽糖10gL-1能显著增加桔小实蝇成虫的诱杀数量。田间试验表明,芒果果浆法能减少果实的受害率。

Abstract: Efficiency of controlling Bactrocera dorsalis adults by lures was studied.Trapping methods and different moisture content and sweetness of trapping agent were compared in a small-scale field test.The results indicated that the poisoned mango paste could trap and kill a large number of B.dorsalis adults.By replacing with fresh mango paste daily the number of trapped fruit flies increased significantly.The addition of 10 gL-1 brown sugar,10 mlL-1 honey and 10 gL-1 maltose to the mango paste could significantly increase the trapping effect even further.It seemed apparent that this method of using mango paste for trapping could considerably minimize the pest infestation in the field
