摘　　要：为了探究发酵木耳菌糠、发酵香菇菌糠和发酵木屑3种饲料对双叉犀金龟幼虫生长发育和营养成分的影响,以及3种饲料作为基质对产卵量与孵化率的影响。采用3种饲料,在27℃、饲料湿度70%条件下饲养双叉犀金龟幼虫,分别测定3龄幼虫的体重、体长、存活率与幼虫体内基本养分物质含量。羽化后用3种饲料作为基质进行雌虫产卵试验,分析不同基质对双叉犀金龟雌虫产卵量与幼虫孵化率的影响。测定并分析饲料营养成分与幼虫营养间的关系。结果表明,在饲养环境条件一致时,发酵木耳菌糠与发酵木屑更有助于双叉犀金龟幼虫生长发育,但体内养分物质含量与另外一种饲料差异不显著。发酵木耳菌糠作为产卵基质时,双叉犀金龟雌成虫产卵量与孵化率显著大于其它两种饲料。发酵香菇菌糠中的总蛋白含量虽然能够保证双叉犀金龟完成生长发育,但纤维素、半纤维素与木质素含量显著低于其它两种饲料,不能代替发酵木屑进行饲养。In order to explore the effects of three kinds of feeds,fermented fungus chaff,fermented mushroom chaff and fermented sawdust,on the growth and development and nutritional components of the larvae of Trypoxylus dichotomus,and the effects of three kinds of feeds as substrates on egg production and hatching rate.Three kinds of feeds,fermented fungus chaff,fermented mushroom chaff and fermented sawdust,were used to feed the larvae of T.dichotomus at 27℃and feed humidity of 70%.The body weight,body length and survival rate of the third instar larvae and the content of basic nutrients in the larvae were measured respectively.After eclosion,three kinds of feeds were used as substrates for female oviposition experiments,and the effects of different substrates on female oviposition and egg hatching rate were analyzed.The correlation between feed nutrients and larval nutrition was determined and analyzed.The results showed that when the feeding environment conditions were the same,fermented T.dichotomus and fermented sawdust were more conducive to the growth and development of the larvae,but the nutrient content in the body was not significantly different from the other two feeds.When the deeply fermented T.dichotomus was used as the oviposition substrate,the oviposition amount and hatching rate of female adults were significantly higher than those of the other two feeds.Although the total protein content in the fermented mushroom bran can ensure the growth and development of the T.dichotomus,the content of cellulose,hemicellulose and lignin is significantly lower than that of the other two feeds,and cannot replace the fermented sawdust for feeding.
