本文通过测定大袋蛾（ＣｌａｎｉａｖａｒｉｅｇａｔａＳｎｅｌｅｎ）幼虫食量、泡桐蓄叶量、模拟危害损失量等试验得出：每头幼虫一生平均食叶量为３７８０～３９８０ｃｍ２，雌虫比雄虫高４０７％；７、８月份泡桐蓄叶量与胸径分别为Ｙ７＝０５３１９Ｄ１６９４９和Ｙ８＝１１３２７Ｄ１４１９９的幂函数回归关系；在模拟危害率３０％以下时，对当年泡桐生长无补偿作用，对翌年泡桐生长有补偿作用；７、８月份材损率与危害程度分别为Ｙ７＝０７２００Ｘ－００１７７和Ｙ８＝０７５７１Ｘ－００１４６的线性回归关系。根据我国泡桐大袋蛾防治方法技术水平的不同，提出了大袋蛾危害１５、２０、２５、３０、３５ｃｍ胸径泡桐时，采用人工注药的防治指标：百叶平均虫口分别为２８０、１７０、１１７、８５、６７头；采用飞机超低容量喷洒灭幼脲的防治指标：百叶平均虫口分别为１８８、１２４、９０、７０、５６头。
In this paper, we test the food intake of Larvae (ClaniavariegataSnelen) larvae, the storage amount of Paulownia, simulating the loss of damage and other experiments. The average larval life of each larvae was 3780 ~ 3980cm2, and the females were 40% higher than the male ones. 7%. In July and August, the leaf volume and diameter of paulownia were power function regression relationship of Y7 = 05319D16949 and Y8 = 11327D14199 respectively. When the simulated damage rate was below 30% Compensation effect on the next year Paulownia growth has a compensatory role; July and August, the damage rate and damage degree were Y7 = 07200X-00177 and Y8 = 07571X-00146 linear regression relationship. According to the technical level of Paulownia moth in our country, we put forward the prevention and cure index of artificial injection when the diameter of 15, 20, 25, 30, 35 cm DBH of the giant pothod moth is as follows: the average insect population of the leaves is 280,170 , 11 7,8 5,6 7 head; the use of ultra-low-capacity aircraft spraying urea control indicators: the average insect population were 18 8,12 4,9 0,7 0,5 6 heads.
