| 摘 要： | 分别以实用饲料和复合饲料在0.6、1.2、1.8、2.4和3.0头/cm3等5种饲养密度下饲养黄粉虫(Tenebrio molitor L.)高龄幼虫,观察了在不同饲料条件下不同密度对黄粉虫幼虫死亡率、幼虫增重、蛹重等指标的影响.结果表明,密度因子对黄粉虫高龄幼虫有显著影响,在两种不同饲料条件下饲养黄粉虫,低密度饲养时幼虫存活率、幼虫增重、蛹重及羽化率明显高于高密度饲养,但各指标间存在差异. |

| Abstract: | Old-age larvae of the yellow mealworm (Tenebrio molitor L.) were reared by two different diets,the practical diet and the complex diet, at densities of 0.6,1.2,1.8,2.4 and 3.0 individuals/ cm3 respectively. The effects of larval density on larval survival,mass,and pupal mass were studied in this paper. The results indicated the effect of density factor on old-age larvae was significant, the larval survival rate, larval mass, pupal mass and emergence rate in low densities were obviously larger than those in high densities when reared by two different diet, while the difference existed among the parameters under two different diet conditions. |
