摘　　要：用改良的玉米螟半人工饲料和天然饲料分别饲养同一批采自野外的细纹豆芫菁 Epicautamannerheimi成虫 .1 0天后从两组各取 2 0头雌虫和 2 0头雄虫 ,经解剖、称重和测定各器官芫菁素含量 ,结果显示 :相对于天然饲料 ,半人工饲料对虫体增重和生殖腺发育有较大促进作用 ,并提高了雄虫虫体和附腺中芫菁素含量 .全程饲养的成虫其处理组的寿命和雌虫产卵量也高于对照组 ,产下的卵有 88%的孵化率 。Adults of Epicauta mannerheimi collected from the field reared on improved semi artificial diet of European Corn Borer and on natural diets were considered to be the experimental group and control group respectively. Ten days later, 20 females and 20 males were taken from each group, dissection, weighing and cantharidin contents detection of body and gonads were conducted. The results showed that, compared with the natural diets, the semi artificial diet obviously promoted the weight gaining and the development of gonads, and arised contents of cantharidin in the whole body and gonads of males. In the all life of the adults, the longevity and ovipsition of the experimental group were higher than those of control group. The hatching rate of eggs laid by the females of experimental group was 88%, and the triangulins grew normally.
