不同食物诱剂对苦瓜园瓜实蝇的诱杀效果

利用蜜糖、红糖、蛋白胨、南瓜作为食物诱剂，研究了不同成分和配方对苦瓜园瓜实蝇的诱杀效果。结果表明，蜜糖液或红糖液添加南瓜饵的诱杀效果显著高于其他诱饵，且这种差异性在苦瓜园外更明显|在3%～10%范围内，红糖液的浓度越高诱杀作用越强，但5%、10%、15%红糖液添加南瓜饵后对成虫的诱杀作用无差异。田间使用中需注意及时更换新鲜诱饵。

Trapping Effect of Different Food Baits Attractant on Bactrocera(Zeugodacus)cucuribitae(Coquillett)in Bitter Melon Park

In order to study the Bactrocera(Zeugodacus)cucuribitae(Coquillett)trapping effect in bitter melon(Momordica charantia L.)park,different food bait ingredients including honey,red sugar,peptone,pumpkin were compared in the field test.The results showed that by adding pumpkin bait to red sugar or honey bait,the trap effect was significantly higher than the other baits,and this difference is more obvious in the bitter gourd park.Within 3%-10% range,the higher is the concentration of red sugar,the stronger the trapping effect.But adding 5%,10%,15% red sugar liquid to pumpkin bait,there are no differences on the role of luring adult.In the field use,fresh bait must be timely replaced.
