棉红铃虫是棉花的主要害虫。利用红铃虫性信息素进行红铃虫的预测预报已经广泛应用并有了新的进展。上海昆虫所李元光、李文谷等在研究性诱剂作迷向防治上取得了一定进展,田间示范应用正在进一步探索。我市1985和1986两年的应用初步认为利用迷向法防治红铃虫是可行的,既减少了田间化学农药的使用次数,减轻了环境污染;又降低了红铃虫的危害,增加了棉花产量,是一项值得推广的防治新技术。 一、应用经过和方法 1985、1986两年由日本信越化学工业株式会社提供的7,11-HDDA外激素药棒在棉
Cotton bollworm is a major pest of cotton. The prediction and forecast of pink bollworm using pink bollworm sex pheromone has been widely used and has made new progress. Shanghai Insect Institute Li Yuan-guang, Li Wen-gu et al. Made some progress in the research on the lure-control of lures and field demonstration applications are being further explored. The application of two years in 1985 and 1986 in our city initially considered that it is feasible to use Radial Method to prevent and control Red Bell Pepper, which not only reduces the frequency of using chemical pesticides in the field, but also reduces the environmental pollution; reduces the harm of Red Bell Pepper, increases the cotton Output is a worthy promotion of new technologies. First, the application of methods and methods 1985,1986 two years by Japan’s Shin-Etsu Chemical Co., Ltd. 7,11-HDDA hormone bar in the cotton
