南美斑潜蝇成虫活动规律的观察

Flight and daily activity of Liriomyza huidobrensis.

应用黄板法对南美斑潜蝇活动特性进行观测。结果表明，南美斑潜蝇在作物顶端层飞翔种群数较高，在此层面黄板诱集成虫数量最大。在干热季南美斑潜蝇的日活动高峰在８∶００～１０∶００和１８∶００～２０∶００，成虫量与日气温呈负相关。

The flight and daily activity of Liriomyza huidobrensis in some vegetable crops were studied by yellow trap. The results showed that the population of adult L. huidobrensis near the top layer of crops was more than that from other spatial parts in fields. In the dry-hot season the population peak of the adult leafminer appeared from 8∶00 to 10∶00 and from 18∶00 to 20∶00. There was a significant negative correlation between catches of L. huidobrensis and temperature
