9种颜色诱虫板对牛角花齿蓟马的诱集作用

2005年8-9月在甘肃农业大学草业学院苜蓿地,采用9种颜色的诱虫板(15 cm×25 cm)对牛角花齿蓟马(Odonotothrips loti)进行了诱集试验。结果表明,其诱集能力依次为黄色、白色、苜蓿花紫色、天蓝色、绿色、蓝色、玫瑰红色、红色、紫色,连续5 d诱集成虫的平均数分别为52.04,19.73、17.53、14.25、13.85、10.96、7.17、4.46、0.08头。分析认为前3种色板可经济有效地用于苜蓿蓟马种群数量监测及预测预报。

Attracting ability of insect-attracting boards with ninecolours to Odonotothrips loti in alfalfa field

Attracting ability of insect-attracting boards with nine colours(15 cm×25 cm) to Odonotothrips loti in alfalfa field in Lanzhou was tested from August to September in 2005.The results indicated that the attracting ability of different boards was varied and shown the following order:yellow,white,alfalfa flower-like purple,azure,green,blue,rose red,red,purple.And their average numbers of trapped insects within 5 days were 52.04,19.73,17.53,14.25,13.85,10.96,7.17,4.46 and 0.08 respectively.The results showed that the boards with yellow,white and alfalfa flower-like purple could be used for monitoring the population of Odonotothrips loti.
