摘要
利用黄色、白色、红色、蓝色、绿色和浅绿色6种不同颜色色板对春玉米田灰飞虱的诱集效果进行了研究。结果表明,灰飞虱对黄色板趋性最大,与其它5种色板存在极显著差异(P<0.01);在整个调查期间,灰飞虱的虫量以雄虫居多,占灰飞虱总量的72.49%,高峰期雌雄比为0.44∶1;利用黄板诱集是进行灰飞虱种群监测和防治的有效手段。
The trapping effect of six types of colored sticky cards, including yellow, white, red, blue, green and light-green ones, on small brown planthopper (Laodelphax striatellus) was investigated in spring corn fields. The small brown planthopper significantly preferred yellow cards to others ( P 〈 0.01 ). During the survey, the number of male small brown planthopper was always larger, accounting for 72.49% of the total. In the thriving occurrence periods, the sex ratio of the females to males was 0.44: 1. All the results showed that the yellow sticky card was the most effective one for monitoring and controlling the small brown planthopper.
