研究了栗山天牛Massicus raddei(Blessig)成虫的日活动节律,结果表明,栗山天牛成虫的取食、交配、产卵、爬行和飞翔等行为的昼夜节律均表现为单峰型。其取食的高峰期是在晚上18时至20时;交配高峰期为17时至22时;产卵和爬行的高峰期均为19时至22时;飞翔的高峰期为19时至21时。提出了昆虫活跃值的概念及其计算方法,并应用该方法评价了栗山天牛成虫的群体活跃值,结果表明,栗山天牛成虫的群体活跃值日变化规律亦为单峰型,而且不同时间的活跃值差异极显著,成虫主要在下午16时至晚上24时活动,高峰期是天黑以后的19时至21时。在高峰时段,栗山天牛雌雄成虫的活跃值差异不显著,但部分行为存在较大差异。不同天气条件下栗山天牛成虫的活跃值差异显著,晴天成虫的活力最强,阴天次之,雨天成虫的活动能力最弱,而且全天没有明显的活动高峰期。温度在22℃～26℃、相对湿度在50%～80%时利于天牛成虫的活动。
The daily activity rhythm of adult adults of Massicus raddei (Blessig) was studied. The results showed that the circadian rhythms of feeding, mating, oviposition, crawling and flying of the adults of the chestnut were all unimodal. The peak of their feeding is from 18:00 to 20:00; the peak of mating is from 17:00 to 22:00; the peak of spawning and crawling are from 19:00 to 22:00; the peak of flight is from 19:00 to 21:00 . The concept of active value of insect and its calculation method were put forward. The population activity value of adults of Chestnut were evaluated by this method. The results showed that the diurnal variation of population activity of adult was also single peaked, There was a significant difference in the activity value between the two groups. Adults mainly live from 16:00 to 24:00 and the peak time is from 19:00 to 21:00 after dark. At the peak time, there was no significant difference in the activity value of the adult male and female adults of Beesia gracilis, but there were some differences in some behaviors. Under different weather conditions, the activity value of adults of the chestnut celastrus was significantly different. The sunny adults had the strongest vitality, the cloudy days followed by the weakest activity of the rainy adults, and there was no obvious activity peak throughout the day. When the temperature is between 22 ℃ ~ 26 ℃ and the relative humidity is between 50% ~ 80%, it is beneficial to the activity of the adult cow.
