摘要
通过柱形和棱形2款不同形状和红、黄、绿、褐、银5种不同颜色的诱捕器林间诱捕效果试验,比较了形状及颜色对松墨天牛成虫诱捕效果的影响。结果表明,形状和颜色都能显著影响松墨天牛成虫的诱捕效果,甚至还直接影响诱雌或诱雄能力。柱形诱捕器诱捕效果(10.47±1.01头)显著优于棱形诱捕器(7.07±0.85头);但棱形诱捕器诱雌能力更强,雌性比高达0.70±0.03。褐色诱捕器诱得松墨天牛成虫(20.67±5.46)头,显著高于红色诱捕器诱虫量(7.67±2.91)头及黄色诱捕器诱虫量(8.33±1.76)头;仅银色诱捕器诱得成虫雌性比为0.41±0.04,其他颜色诱捕器诱得成虫雌性比均达0.60左右,存在显著差异(P=0.05)。
The trapping effects of traps of two shapes（column and prism） and five colors（red,yellow,green,brown and argent） were studied in the forest.The influence of shapes and colors of traps on trapping effect on Monochamus alternatus Hope were also compared.The results showed both shape and color could significantly influence the trapping effect and even the sex ratio of Monochamus alternatus trapped.The column traps trapped much more beetles（10.47±1.01） than prismatic traps（7.07±0.85）,but prismatic traps could trap more females with a female rate of 0.70±0.03.The brown traps trapped much more beetles（20.67±5.46） than the red traps（7.67±2.91）and yellow traps（8.33±1.76）.The female rates of the beetles trapped by traps of all colors were about 0.60 except that of the beetles trapped by argent traps which was just 0.41±0.04.There were significant differences between the argent traps and traps of the other four colors（P=0.05）.
