摘要: 通过田间防治试验与系统诱捕调查相结合的方法,探明苦瓜地诱捕瓜实蝇雄成虫的数量动态和瓜实蝇对苦瓜的危害损失率,测定苦瓜的经济允许损失率分别为2.85%~3.09%。通过回归分析,建立苦瓜损失率与瓜实蝇雄成虫的诱捕数量的关系模型,测定瓜实蝇的经济阈值为每个诱捕器5.3~5.8只。

Abstract: By the way of system investigation and field control experiment,the quantity dynamics of entrap melon fly male adult and damage ratio to Balsam pear,the economic permission damage ratio were established as 2.85%-3.09%,the relationship model between damage ratio and quantity of entrap melon fly male adult were developed,and the economic threshold of melon fly were established as 5.3-5.8 adult per entrapper during ten days.
