作者对稻飞虱［白背飞虱Ｓｏｇａｔｅｌｌａｆｕｒｃｉｆｅｒａ（Ｈｏｒｖａｔｈ），褐飞虱Ｎｉｌａｐａｒｕａｌａｌｕｇｅｎｓ‘ｓｔａｌ］的测报办法做了改进，拟订了查卵预测主害代发生程度的标 ，并建立田间百丛着卵量与虫量关系的回归预测式Ｙ＝─０．０５９２＋０．７８３４ｘ±０．１６２６。以百丛有效卵预测稻飞虱发生程度和以成虫产卵高峰日加５～７天为若虫发生高峰期，可在害虫发生危害前１０天发出短期预报。验证表明，改进后的预测法掌握防治适期实用性较强，可减少防治次数和费用。
The authors improved the reporting method of the rice planthoppers Sogatellafurcifera (Horvath) and Nilaparualalushtanes (brown planthopper) and developed a standard for predicting the occurrence of the major offspring of the rice planthoppers The regression relationship between the quantitative prediction Y = ─ 0.0559 + 0.7834x ± 0.1626. In order to predict the occurrence of planthoppers by using plexiform eggs and to increase the peak of adult spawning days by 5 ~ 7 days, the nymphs could be issued a short-term forecast 10 days before the occurrence of pests. The verification shows that the improved forecasting method has strong practicality in controlling the appropriate period of control, and can reduce the number and cost of prevention and control.
