苦瓜瓜实蝇的生物学特性及毒力测定

Biological characteristics and toxicity determination of Bactrocera cucurbitae

将将海南苦瓜生产中的重要入侵害虫瓜实蝇Bactroeera（Zeugodacus）cucurbitae（Coquillett）带回室内人工饲养，针对人工饲料、饲养方法及生长发育规律进行探索，发现在气温高达28-30℃时瓜实蝇各发育历期均有缩短．成虫最喜欢取食煮熟的南瓜、喜欢在整条的新鲜青瓜上产卵，幼虫饲养最佳选择也是新鲜青瓜。药剂毒力测定时药膜法比浸虫法操作简单且结果更为稳定，测定结果表明，供试药剂的最佳选择是阿维菌素，其次是甲氨基阿维菌素苯甲酸盐、溴虫腈及啶虫脒。

Bactrocera （Zeugodacus） cucurbitae （Coquillett） are important invasive pest in bitter gourd production in Hainan,we took them back to the indoor artificial feeding room for research. After oberserving the artificial diet, feeding methods and the growth development, we found that, when the temperatures was 28-32℃, their developmental duration would be shortened. Adult liked to eat the cooked pumpkin, and liked to spawn in the whole fresh cucumber. Larval＇s favorite food were also fresh cucumber. The toxicity of 9 pesticides against mature larvae and pupae of B. cucurbitae were determined by the residual film method and dipping method. The results showed that residual film method was simpler than the dipping method and the result was more stable. Abamectin was the most effective against B. cucurbitae, followed by emamectin benzene formate, chlorfenapyr, acetamiprid.
