未交配的成年雌性科罗拉多马铃薯甲虫，Leptinotarsa decemlineata（Say），被吸引到损坏和化学处理的马铃薯植物在嗅觉仪。与未受损的植物相比，显著更多的甲虫逆风移动到马铃薯植株，与幼虫科罗拉多马铃薯甲虫的损害。与未受损的植物相比，更多的甲虫逆风向用来自科罗拉多马铃薯甲虫幼虫或甘蓝夜蛾幼虫（Trichoplusia ni（Hubner））的杀虫剂处理的马铃薯植物移动。与未处理的植物相比，更多数量的甲虫逆风向用N -（17-羟基亚麻酰基）-L-谷氨酰胺（volicitin）处理的马铃薯植物或用植物激素茉莉酸甲酯处理的植物移动。机械损伤马铃薯叶片没有增加甲虫吸引力时，植物进行了测试1或24小时后受伤。这些结果表明，由植物产生的挥发性化学物质，在刺激喂养幼虫增强了吸引力的植物雌性科罗拉多马铃薯甲虫。
Unmated adult female Colorado potato beetles, Leptinotarsa decemlineata (Say), were attracted to damaged and chemically treated potato plants in an olfactometer. Significantly more beetles moved upwind to potato plants with damage from larval Colorado potato beetle compared with undamaged plants. More beetles moved upwind toward potato plants treated with regurgitant from Colorado potato beetle larvae or cabbage looper larvae, Trichoplusia ni (Hubner), compared with undamaged plants. Greater numbers of beetles moved upwind toward potato plants treated with N -(17-hydroxylinolenoyl)-L-glutamine (volicitin) or to plants treated with the plant hormone methyl jasmonate, compared with untreated plants. Mechanical injury to potato foliage did not increase beetle attraction when plants were tested 1 or 24 h after injury. These results indicate that volatile chemicals produced by the plant in response to stimuli from feeding larvae enhance the attractiveness of the plant to female Colorado potato beetles.
