茶黄蓟马(Scirtothrips dorsalis Hood)近年来已逐渐上升为荷花的主要害虫。2012年对深圳市洪湖公园茶黄蓟马发生特点、中间寄主种类及色板诱集效果等进行了研究。结果表明,茶黄蓟马对黄色和绿色具有强烈的正趋性,并具有转移为害寄主的特点。在春、冬季主要集中在红绒球、美人蕉、扶桑和假连翘等中间寄主上,荷花新叶浮出水面后,茶黄蓟马即从中间寄主转移到荷花上为害。提前对中间寄主上的茶黄蓟马进行防治,可推迟该蓟马转入到荷花上为害的时间,并降低虫口密度。
Scirtothrips dorsalis Hood in recent years has gradually increased to the main pests of lotus. In 2012, the characteristics of Ocimum thrips tabaci in Honghu Park of Shenzhen City, the species of middle host and the effect of color trap were studied. The results showed that the yellow thrips had a strong positive trend toward yellow and green, and had the characteristics of transferring host harm. In the spring and winter are mainly concentrated in the red ball, canna, hibiscus and forsythia and other intermediate host, the new leaves of lotus surfaced, the yellow thrips from the intermediate host to the lotus damage. Preventing and controlling the yellow thrips in the middle host may delay the time when the thrips is transferred to the lotus and reduce the population density.
