蝙蝠蛾幼虫食料初步筛选及其取食研究

    Preliminary screening of feed materials for Hepialus larvae and study on its feeding habits

    • 摘要: 为获得适合低海拔地区蝙蝠蛾规模化人工饲养的幼虫食料,对常见且营养丰富的食料或中药材进行初步筛选,并分析比较蝙蝠蛾5龄幼虫对所筛选食料的取食情况与效果,结果表明:在试验的15 d内,胡萝卜(CK)、人工饲料及太子参干品不发生变质;幼虫不取食太子参干品,喜食胡萝卜与白菜叶,但白菜叶湿度极大不利幼虫生长;白菜叶组、番薯组、鲜玉米粒组和人工饲料组幼虫增重极显著高于槟榔芋组及胡萝卜组;鲜玉米粒组、人工饲料组的食物转化率均高于8%,番薯组约为7%,三者的食物转化率极显著高于胡萝卜组。

       

      Abstract: Common and nutritive food and Chinese medicinal materials were preliminarily screened to select the suitable feeds for the large-scale artificial rearing of Hepialus larvae in low-altitude area, and the feeding habits of the fifth instar larvae on selected feeds were analyzed. The results showed that carrot, artificial feed and the dried Radix pseudostellaria would not deteriorate in 15 days; the larvae refuse to feed on dried Radix pseudostellaria, like to feed on carrot and cabbage leaves, but cabbage leaves were bad to the larvae growth because of its large moist content; the weight increase of larvae fed cabbage leaf, sweetpotato, fresh corn and artificial feed was higher than Colocasia esculenta and carrot with very significant difference; the food conversion rate of fresh corn and artificial feed were both higher than 8.00%, and sweetpotato was 7.00%, which were all significantly higher that of carrot.
