１９９５～１９９７年对豆荚螟危害损失研究结果表明，大豆单株产量损失率（％）与卵量（粒）的关系式为：Ｙ＝－１．４２３４＋２．０９５１ｘ；大豆单株产量损失率（％）与幼虫量（头）的关系式为：Ｙ＝２．４３０３＋２．４６００ｘ；大豆单株产量损失（ｇ）与卵量（粒）的关系式为Ｙ＝－０．７３９７＋０．３６８７ｘ；大豆单株产量损失（ｇ）与幼虫量（头）的关系式为：Ｙ＝０．１５５１＋０．４１７４ｘ。经计算和大田验证，大豆田块豆荚螟防治指标为３４３～２４５（粒）卵／百株。
The results of the study on the damage to soybean leaf borer from 1995 to 1997 showed that the relationship between the yield loss (%) of soybean and the amount of eggs (grain) was: Y = -1.4234 + 2.0951x; ) And the amount of larvae (head) were: Y = 2.4303 + 2.4600x; the relationship between the loss of yield per plant (g) and the amount of eggs (granules) was Y = -0.7397 + 0.3687x; The relationship between yield loss (g) and larval volume (head) is: Y = 0.1551 + 0.4174x. After calculation and field validation, soybean field pod borer control indicators 343 ~ 245 (grain) eggs / one.
