<正>用灭幼脲处理补充营养寄主植物连续饲养云斑天牛成虫，在产卵初期和中期，处理雌虫血淋巴蛋白质含量明显下降。在产卵末期，处理雌虫血淋巴蛋白质含量则高于对照组。聚丙烯酰胺凝胶电泳分析表明：灭幼脲处理后血淋巴蛋白质种类无明显变化。灭幼脲对蛋白质含量的影响因蛋白质的种类而异，对雌性特异性蛋白（迁移率２．５％～１２．６％）含量有明显抑制作用，对迁移率３３．１％～３６．７％的蛋白质谱带有促进作用。结果表明：灭幼脲对云斑天牛成虫具有类似于保幼激素的效应，处理成虫血淋巴蛋白质含量变化则是这一效应的结果。

Adult Batocera horsfieldi were fed with the adult host plant treated by diflubenzuron In the early and middle stage of egg layingseason， the haemolymph protein concentration of treated female dropped evidently In the late egg layingseason， the haemolymph protein concentration of treated female was higher than that of untreated control female The polyacrylamide gel electrophoretic pattern suggested that the number of protein fractions had no significant change between the treated and untreated adults Diflubenzuron had different effects on individual protein fractions Diflubenzuron had an evident inhibition on the concentration of female specific proteins， the relative migration values varied from 2．5 percent to 12．6 percent Meanwhile， it stimulated the concentration of the fractions with relative migration values between 33．6　percent and 36．7 percent These results suggested diflubenzuron had the effects siminar to juvenile hormone on adult Batocera horsfieldi Changes of haemolymph protein concentration of the treated adult were caused by its juvenile hormonelike effects
