本文研究了广华枝ＳｉｎｏｐｈａｓｍａｌａｒｇｕｍＣｈｅｎｅｔＣｈｅｎ的食叶量。其一生食叶量为２０．８０２ｇ，其中１～４龄低龄若虫期的食量占其一生食量的３．１３％，５～６（７）龄老龄若虫期的食量占２１．９５％，成虫期的食量占７４．９２％，老龄若虫期和成虫期是主要的危害期，占其一生食量的９６．８７％；并建立了个体食叶量模型、个体日均食量模型及其活动量指数增长模型，分别为Ｘ１＝０．０３９４ｅ０．５９７９Ｘ０，校正Ｒ２＊＊＝０．８９３１；Ｘ２＝２６．５１７６ｅ０．２２３３Ｘ０，校正Ｒ２＊＊＝０．７６７３；Ｘ３＝１．３０９３ｅ０．５００１Ｘ０，校正Ｒ２＊＊０．９４４０，复相关系数平方显著或极显著；胸径为８～１２ｃｍ的寄主，其防治指标为９３．１头，并提出了防治意见。
In this paper, the leaf volume of SinophasmalargumChenetChen was studied. The lifespan of the leaves was 20.802g, of which the food intake of the first to the fourth instar nymphs accounted for 3.13% of their lifetime food intake, and the food intake of aged 5 ~ 6 (7) aged nymphs accounted for 21.95% Of the total food intake accounted for 74.92% of the total, and the nymphal stage and adult stage were the main damage periods, accounting for 96.87% of their lifetime food intake. The individual leaf intake model, daily average daily appetite and activity index were established Model, respectively, X1 = 0.0394e0.5979X0, the calibration R2 ** = 0.8931; X2 = 26.5176e0.2233X0, the calibration R2 ** = 0.7673; X3 = 1.3093e0.5001X0, the calibration R2 ** 0.9440. The square of the correlation coefficient was significant or extremely significant. The host with the diameter of 8 ~ 12 cm was 93.1 and its control index was put forward.
