吴文君曾详细介绍了昆虫拒食剂的生物测定方法,包括圆叶片法及改进的圆叶片法、体重法、排泄物法和电讯号法[1]。测试方法不同,昆虫拒食剂拒食活性的数字表示就会不同。大多数植物次生代谢物,如印楝素、川楝素、苦楝醇等的拒食活性常用甘蓝叶碟法进行选择性和非选择性测定。为 Wu Wenjun has described in detail the bioassay of insect repellents, including the round leaf method and improved round leaf method, body weight method, faecal method and the electric signal method [1]. Different test methods, insect antifeedant food antifeedant figures that will be different. Most of the plant secondary metabolites, such as azadirachtin, toosendanin, azadirachtin and other antifeedant activity commonly used cabbage leaf dish selective and non-selective determination. for
