二化螟是我市水稻主要害虫之一,目前用灯诱、剥查田间幼虫发育进度等常规测报方法预报二化螟的发生,较为费工费时。1989年我们将性诱剂用于二化螟测报,以期改进和完善测报手段,提高预测预报的准确性。一、方法二化螟性信息素诱芯由江苏省金坛激素研究所提供,诱芯用铁丝横穿,平放在水盆上,水盆口径有20cm 和30cm 两种规格,盆内设有装0.2%洗衣粉液、0.1%一六○五药液和清水三种处理,将水盆分别放在50cm、100cm 不同高度的钢筋三角架上,三角架顶端装有伞形篷盖,防止雨水冲淋。
Chilo suppressalis is one of the main rice pests in our city. At present, it is more time-consuming and labor-intensive to predict the occurrence of Chilo suppressalis by conventional methods of forecasting such as light luring and stripping of field larvae. In 1989, we used the lure for the test of Stem Borer in order to improve and improve the means of measuring and improve the accuracy of forecasting. First, the method of sex-pheromone pyrethrum induced by the Jiangsu Province Jintan Institute of Hormone, induced by wire crossing, flat on the basin, basin diameter 20cm and 30cm two specifications, the basin is provided Equipped with 0.2% detergent solution, 0.1% of the liquid and water treatment of water, put the basin on 50cm, 100cm different height of the steel tripod, tripod top with umbrella canopy, to prevent rain Shower.
