| 摘 要： | 在山杜英上为害的吉丁虫Chrysobothris igai Kurosawa属国内新记录。该虫在衢州1a发生1～2代，越冬休眠幼虫在4月底-5月化蛹，1代成虫主要集中在6月上旬，7月为1代幼虫为害高峰，8月后部分1代老熟幼虫侵入木质部筑蛹室化蛹，8月底-9月出现2代成虫。还有部分发育稍迟的，以l代幼虫老熟后侵入木质部筑蛹室后直接进入休眠越冬，表现为1a 1代。9月后多有生活史重叠，10月下旬至11月2代老熟幼虫侵入木质部做蛹室，在蛹宣休眠越冬。作者在查清其在山杜英上发生和为害规律的基础上，提出应采取营林措施、检疫措施、人工、生物、化学防治等综合对策进行防治。

| Abstract: | Chrysobothris igai attacking Elaeocarpus sylvestris is a new record in China.It has one or two generations in Quzhou.The overwintering larva pupates between the end of April and May and the 1st generation adult emerges mainly in the first ten days of June.The peak of damage caused by the larva of the 1st generation is in July.Some of the mature larvae bore into xylem in August and then pupate.The 2nd generation adult emerges between the end of August and September.Some of the 1st generation larvae develop late and the mature larva bores into the xylem and then begins to overwinter.They are one generation a year.The generations overlap after September.The mature larva of the 2nd generation bores into the xylem and overwinters between October and November.Some control countermeasures were suggested in the paper. |
