以往预测褐稻虱若虫孵化高峰期,均采用成虫高峰日加产卵前期再加卵发育历期的方法,预测结果与田间实际发生情况始终不相吻合,因而往往增多防治次数和农本.为了提高褐稻虱发生期预测的准确性,1976～1977年对褐稻虱的产卵规律进行了研究. In the past, the nymphs of brown planthopper nymphs were predicted to adopt the method of peak adult day plus pre-ova egg developmental period, and the predicted results did not coincide with the actual occurrence in the field, so they often increased the number of control and Nong Ben. Improve the prediction accuracy of the brown planthopper stage, from 1976 to 1977 on the brown planthopper oviposition rules were studied.
