【摘要】 为探索灯诱栗山天牛成虫更加经济有效的方法,利用太阳能灯诱灭虫器装上诱集效果最好波长的灯管和食物源引诱剂,对栗山天牛成虫进行了林间诱杀试验。结果表明:2017年栗山天牛成虫在辽宁省宽甸县出现的高峰期是7月21日,每日单灯平均诱集量最高达212.7头。7月12日的雌性比率均值最低(<0.50),栗山天牛发生前期诱集雄虫较多;而7月16日至8月9日的雌性比率均值都大于0.50,诱集雌虫较多;7月26日以后诱虫数量开始下降;诱杀成虫的最佳时间是7月16-26日。采用太阳能灯诱灭虫器并结合使用食物源引诱剂能自动淹杀诱来的天牛成虫,诱杀效率高,值得在生产中大面积推广应用。更多还原

【Abstract】 To explore more economic and effective method against Massicus raddei adults, solar lamp had been used with the optimum trapping wavelength of bulb and food source attractants. The results showed that the emergence peak of adults appeared on July 21, 2017 in Kuandian County, Liaoning province, and the average trapped quantities by single lamp was up to 212.7 per day. On July 12, the average female percentage was the lowest(< 0.50), indicating that M. raddei males were more than females at the early stage of adult flight. From July 16 thto August 9 th, female percentage was greater than 0.50, indicating that on July 16 thto August 9 ththe number of females was more than males, but after July 26 trapped insects began to decline. The best trapping dates were July 16 ~ 26. This experiment method using solar lamp trap combined with food attractant could automatically kill M. raddei adults, with highly trapping and control efficiency,which was worthy to be recommended to extend and use in practice.更多还原
