摘要
通过对杭州市萧山区星天牛在红花檵木上的生活规律进行调查,研究表明:萧山区星天牛在红花檵木上1年发生1代,以幼虫在被害树干基部或根部越冬。在次年3月下旬、4月上旬开始活动取食,4月中、下旬开始化蛹,5月中旬开始陆续羽化,6月初至7月中旬为成虫盛发期,7月下旬逐渐减少。成虫羽化后不久即可产卵,7月中旬为产卵盛期。幼虫孵化后开始为害,幼虫期约10个月。星天牛防治以6月初至7月上旬防治成虫为宜。
The results showed that: Anoplophora chinensis attacking Loropetalum chinense had one generation a year in Xiaoshan and overwintered as larva in the xylem of the trunk or roots. It revived in late March the next year, pupated in mid and late April, emerged in mid May with a peak from early June to mid July, and mated and laid eggs shortly after the emergence. In mid-July, it got into the spawning peak. After the larvae hatch, they begin their infestation, and the larval period is about 10 months. The appropriate time for the control against the adult is from early June to early July.
