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 yellow board method was used to observe the activity characteristics of the leaf plum. The results showed that the population of Liriomyza sativae flying at the top of the crop was high, and the largest number of yellow-lured adults was at this level. In the hot and dry season, the daily activities of the leafminers were between 8:00 ~ 10:00 and 18:00 ~ 20:00. The adult temperature was negatively correlated with the daily temperature.
