摘要
通过室内饲养和室外笼养观察研究了余姚地区松褐天牛成虫的羽化规律。结果表明:松褐天牛在室内开始羽化的时间晚于室外,但羽化盛期基本一致。野外成虫羽化受气候影响较为明显,不同的年份羽化始期不同,但羽化盛期基本一致。另外,高山地区松褐天牛的羽化期比平原地区推迟30d左右。
The emergence rule of Monochamus alternatus was studied based on observation in the laboratoy and investigation in the field in Yuyao. Results indicated that the initiative time of adult emergence was posterior in the laboratoy to in the field, though the peak was the same. The emergence rule of Monochamus alternatus was affected distinctly by climate change, and initiative time of emergence was disparate in different years though the peak times of emergence were almost the same. In addition, the time of emergence in mountain areas was suspended for 30 days in contrast to the time in plain areas.
