摘　　要：2006～2007年,利用频振式杀虫灯和高压汞灯对蔗根土天牛成虫进行田间诱捕试验。结果表明,蔗根土天牛成虫出土时期比较集中在4～6月,不同年份不同气温出土时期略有差异,气温高的年份出土时期提前;蔗根土天牛成虫在19:00～21:00时段活动频繁,扑灯率较高;成虫对光源选择不严格,但跟光源强弱有关。The present experiment was conducted to study the effects of frequency vibration-killing lamp on trapping and killing the adults of Dorysthenes granulosus during the whole period of adult growth in 2006-2007.The results showed that the adults of Dorysthenes granulosus came out of soil concentrating from April to June,and has a little difference in different years when the temperature are varied,and would be ahead of time in high-temperature years.It was found that the activity of Dorysthenes granulosus adults at 19：00-21：00 were in high frequend and had a higher rate of flying towards lights.It was found that the adults had no strict selection for the source of light but there was correlation with the strength or weakness of light source.
