为寻求一套安全、经济、有效易行的综合防治措施,避免滥施农药,1982年我们在围田类型蔗区的番禺县榄核公社牛角大队进行了较大面积的甘蔗螟害综合防治试验,取得了良好的防治效果。 (一)试验方法及经过试验以牛角大队第三生产队为综防区(120多亩),相邻的第二生产队(120多亩)为对照区(常规防治区)。试验前调查虫害发生情况;综防区的螟害节率及死尾率分别为9.6％和17.3％;常规区的分别为10.5％和18.2％。全年综防区贯彻综防措施情况如下: 1.全年诱测田间蔗螟成虫发生消长情况,指导防治。全区共设9个性外激素诱杀盆,每
In order to find a safe, economical and effective comprehensive prevention and control measures to prevent the indiscriminate application of pesticides, we conducted a large-scale comprehensive control experiment on sugarcane borer in the horned brigade of Lancun commune in Panyu County, , Made a good control effect. (A) Test methods and tests The third production team of the Horned Brigade is the comprehensive prevention zone (120 mu), and the adjacent second production team (120 mu) is the control zone (conventional control zone). Pest occurrences were investigated before the experiment. The mortality and dead-end percentages of stem borer were 8.6% and 17.3% in the general-resistant area respectively and 10.5% and 18.2% respectively in the conventional area. The implementation of comprehensive anti-precautionary measures throughout the year are as follows: 1. The annual trap rice stem borer induced growth and decline, guiding the prevention and treatment. The region a total of nine sex hormone trapping basin, each
