中文摘要:在30℃下,研究了饲养密度对洋虫Palembus dermestoides (Fairmaire)幼虫生长发育的影响,并用Weibull频数分布函数探讨了饲养密度对洋虫幼虫存活率的变动影响。结果表明:饲养密度对幼虫存活率影响明显,存活曲线均属于Ⅰ型;但对幼虫体重增长的影响并不显著,饲养密度
英文摘要:The effect of density factor on development of larvae of Palembus dermestoides was studied at 30℃. The relationship between survival and rearing density was analyzed using Weibull frequency distribution. The results indicat that the density have
