| 摘 要： | 本文以主要质量指标对比了用人工半合成饲料与天然饲料饲养银纹夜蛾的结果，表明人工半合成饲料明显优于天然饲料。研究了幼虫饲养密度对存活的影响，四龄末幼虫存活率与一龄幼虫密度呈抛物线关系，化蛹率、蛹重与五幼虫密度呈直线下降关系，相对湿度、夜间光照强度、食物等对成虫生殖有显著影响。

| Abstract: | The present paper deals with comparision of the results of A. agnata fed on artificial and natural diets. The results show that artificial diet is superior to natural diet. This paper also studies effects of density of larvae on survival rate. The relationship between the survival rate of the late fourth instar larvae and the density of the first instar larvae is fitted to the parabolic curve.The relationship between the pupation rate, pupal weight and the density of the fifth instar larvae are fitted to straight lines. Relative humidity, light intensity at night and food have remarkable effects on reproduction of adults. |
