我县地处江西中部,为双季稻区。稻纵卷叶螟Cnaphalocrocis medinalis Guenee常年发生六代,一般以第二、五两代为害重,两代的虫源均以外来迁入为主,在测报上用常规赶蛾法查明发蛾高峰期预报防治适期。但这种方法的准确性甚差,并且还有花工多,易伤害稻株等弊病。笔者曾试用碳酸氢铵水溶液以及碳酸氢铵水溶液配合白炽灯(以下简称碳铵加灯)诱集稻纵卷叶螟蛾子,从而取代常规赶蛾法,用于测报。3年的实践证明,效果良好。
My county is located in central Jiangxi, a double season rice area. Cnaphalocrocis medinalis Guenee, a common perennial species of Cnaphalocrocis medinalis Guenee, takes the second, fifth and twelfth generations as the main cause of pests. The pests of the two generations are mainly migrated by other countries. The peak of the moths Period forecast control period. However, the accuracy of this method is very poor, and there are more flower workers, easy to damage rice and other ills. I have tried ammonium bicarbonate solution and aqueous solution of ammonium bicarbonate with incandescent lamp (hereinafter referred to as ammonium bicarbonate plus light) to trap rice leaf roller moth, which replaced the conventional moth method used for measuring the newspaper. 3 years of practice has proved effective.
