2、林业害虫,造成了严重的经济和生态损失。为探索诱杀栗山天牛的有效技术措施,本研究利用自主研发的专用黑光灯对栗山天牛成虫进行了诱杀技术试验研究。结果表明,将黑光灯设置在山脊是诱集栗山天牛的最佳位置;20:00—22:00是引诱的最佳时间;以天牛成虫羽化前期和末期的雄虫略多,而盛期雌虫略多,但差异不显著。诱集到的雌虫的怀卵量前期和盛期平均30头,和处女雌虫无明显差异,表明诱集到的雌虫为卵刚成熟而未产出的发育阶段的成虫,而在羽化末期诱到的雌虫怀卵量不足10粒/头。和普通手电相比,该专用黑光灯的诱集数量是其2.03倍。晴天诱到的成虫数量远多于阴天
3、。用专用黑光灯诱杀栗山天牛成虫效果显著,将在降低该害虫后代的种群数量上发挥重要作用。关键词:黑光灯;栗山天牛;雌虫;怀卵量中图分类号:Q968.1文献标识码:A文章编号:1674-0858(2010)03-0369-06TrappingtechnologyaboutadultsofMassicusraddeibyaspecialblacklightJIANGJing,YANGZhong—Qi,TANGYan—Long,TANGHua,SUNGuang—Ji,GAOZhi-Qiang(1.TheKeyLaboratoryofForestP
