拟异尾华枝ＳｉｎｏｐｈａｓｍａｐｓｅｕｄｏｍｉｒａｂｉｌｅＣｈｅｎ雌、雄性的个体取食量：雌性一生总食叶量为１７．８８ｌｇ，其中１～４龄低龄若虫期的占５．４８％，５～７龄老龄若虫期的占２２．７１％，成虫期的占７１．８１％；雄性为７．２１５ｇ，其中１～４龄低龄若虫期的占６．２０％，５～６龄老龄若虫期的占３１．１０％，成虫期的占６２．７０％，老龄若虫期和成虫期是主要的危害期；并分别建立了雌、雄性个体食叶量、个体日均食量指数增长模型，胸径为８～１２ｃｍ的寄主，其防治指标为１５８．４头。

The number of female and male individual feeding was 17.88lg for the female and male, which was 5.48% for the first to fourth instar nymphs and the fifth to seventh instar nymphs Accounting for 22.71%, adult accounted for 71.81%; male was 7.215g, of which 1 to 4 years of age nobility accounted for 6.20%, 5 to 6 years old nymph accounted for 31.10% The adult nymphs accounted for 62.70%, and the nymphae nymphs and adult nymphs were the main harms. The female and male individuals were also given the index of leaf opening, the daily average daily appetite, the diameter of 8 ~ 12cm, Control indicators for the 158.4 head.
