根据每日诱虫数量绘制出主要害虫成虫羽化曲线，据此可以预测害虫的发生世代、发生期和发生量，为科学防治提供依据。

According to the number of pests trapped per day , the emergence curves of main pests were drawn to forecast the generation , occurrence time and population .

水生昆虫中的摇蚊幼虫在富营养湖泊中的密度大，能摄食消化大量的沉积有机碎屑，成虫羽化后离开水体飞往陆地。

The density of Chironomid larvae in the eutrophic lake is high . They can consume a large amout of organics detritus before the adult emergence and fly away to land .

光照条件下羽化高峰期为1420时，在25时羽化率最低.这表明成虫羽化受光周期和温度的影响且具有明显的昼夜节律。

The lowest emergence ratio was found during 2:00 - 5:00 . It was concluded that the adult emergence was influenced by light rhythm and temperature , and also had a day night rhythm .

成虫羽化节律观察表明，大部分成虫（雌虫、雄虫）于上午7时至下午19时羽化。据对113头蛹的观察，蛹羽化率为82.5%，羽化高峰在13时。
