摘　　要：为探寻冬虫夏草寄主幼虫生长发育障碍受胡萝卜和珠芽蓼影响的原因。对贡嘎蝠蛾(Hepialus gonggaensis)的饲料珠芽蓼及胡萝卜的营养成分进行测定分析。结果表明,珠芽蓼与胡萝卜均含有丰富的营养成分,在常规营养成分、维生素、矿质元素、氨基酸含量上,珠芽蓼要普遍高于胡萝卜,同时,珠芽蓼中富含对昆虫生长发育至关重要的胆碱,高达11.20 mg/100g,在胡萝卜中未检出(<2.0 mg/100g),初步推断胡萝卜中的胆碱的缺失或含量极低可能是导致冬虫夏草寄主蝠蛾高龄幼虫生长不利的因素之一,现阶段采用珠芽蓼混合胡萝卜的饲喂模式适宜于冬虫夏草寄主幼虫的生长。To find out the reason that the growth retardation of host Hepialus larvae of Cordyceps sinensis was affected by Polygonum viviparum L.and Daucus carota L.,two forage＇s nutritional components of Hepialus gonggaensis were detected and analyzed.The results showed that both of them contained abundant nutritional components,and P.viviparum L.was generally higher than D.carota L.in nutritive ingredients,including mineral elements,vitamins and amino acids,meanwhile,the choline which played an improtant role in insect development ouly existed in P.viviparum L.as much as 11.20 mg/100g,but the choline did not exist in D.carota L.,which probably was a cause of the larva not growing well.It was proved that feeding the larva with P.viviparum L.mixing D.carota L should be a better measure.
