摘要
黄曲条跳甲是十字花科蔬菜上的重要害虫。采用黄板诱集,通过2005～2006年连续系统的监测,结合气象资料进行系统分析,结果表明,每年4～11月为成虫活动的活跃期。1年有春夏季高峰和秋季2个高峰期。春夏季高峰发生量明显高于秋季高峰发生量。日平均气温稳定通过10℃初日、终日分别可确定黄曲条跳甲成虫活动频繁的初始和结束日(进入越冬期);日平均气温稳定通过26℃初日、终日为黄曲条跳甲成虫进入活动减弱期的起始和结束日;黄曲条跳甲成虫活动高峰期一般出现在日平均气温17.5～24.4℃的温度区域内。
Phyllotreta striolata was an important pest damaging crucifer vegetable. Phyllotreta striolata were trapped by yellow sticky board, continuously survey was conducted between 2005 and 2006, and system analysis was done with help of meteorological data. Results showed that activity of Phyllotreta striolata＇ adult was active from April to November, had two peaks of incidences （spring and summer, autumn） in a year. Spring and summer peak is higher than those in autumn. When daily average temperature above 10 ℃, adults of Phyllotreta striolata became more active. But when daily average temperature exceeding 26 ℃, the activities of Phyllotreta strillata＇s adults decreased. In general, the peaks of its activities of appeared at daily average temperature between 17.5 and 24.4 ℃.
