Abstract

The insect industry is a promising agricultural resource and expected to grow steadily. In Korea, Gryllus bimaculatus and the larvae of Tenebrio molior, Protaetia brevitarsis, and Allomyrina dichotoma were listed as general food ingredients. As interest in these edible insects increases, rearing techniques and nutritious food sources are needed for mass production. In this study, wheat bran, dog feed, and pig feed were investigated for their effects on the larval growth of P. brevitarsis and A. dichotoma. When fermented sawdust with 30% wheat bran was used, the larval survival rate of P. brevitarsis and A. dichotoma (p=0.244341 and p=0.007966, respectively) and growth rate (p=0.001400 and p=0.000051, respectively) were significantly lower than those of the control (fermented sawdust with no supplement). Therefore, fermented sawdust with a high density of wheat bran was inappropriate for both insects. When fed fermented sawdust with 2.5 or 5% of dog and pig feed, the survival rate and growth rate of the larvae were higher than those of the control. Interestingly, the maximum larval weight with 2.5% dog feed was increased by $3.35{\pm}0.10g$ and $32.59{\pm}0.79g$ for P. brevitarsis and A. dichotoma, respectively. In addition, the larval period of both was shorter than that of the control by 40 days or more. Therefore, it is considered that animal feed can be used as a feed source for these edible insects.

곤충은 식량 기능성 소재 농업자재 등 미래의 농업자원으로 유망하며, 지속적인 시장성장이 예상되고 있다. 또한 갈색거저리 유충, 쌍별귀뚜라미, 흰점박이꽃무지 및 장수풍뎅이의 유충이 일반식품원료로 인정됨에 따라 식용곤충에 대한 관심이 높아지고, 이에 대량생산을 위한 사육기술의 표준화 및 먹이원 개발에 관한 연구가 요구되고 있다. 본 연구는 흰점박이꽃무지와 장수풍뎅이 유충의 발육촉진 효과를 확인하기 위해 애견사료 및 양돈사료와 같은 시판 중인 가축사료와 밀기울을 첨가한 발효톱밥을 이용하였다. 밀기울 첨가 처리구는 흰점박이꽃무지와 장수풍뎅이의 생존율과 증체율이 현저히 낮은 수준으로 곤충 먹이원의 소재로 사용되기에 부적합한 발육양상을 보였다. 애견사료 및 양돈사료를 첨가한 먹이원을 급여하였을 때 흰점박이꽃무지와 장수풍뎅이 모두에서 유충의 생존율 및 증체율이 높고 유충기간이 단축되는 것으로 나타났다. 특히, 애견사료 5% 첨가 조건에서 흰점박이꽃무지 유충의 증체율은 초기 무게와 대비하여 179.2%로 가장 높았고, 장수풍뎅이 유충의 증체율은 애견사료 2.5% 첨가 조건에서 299.9%로 가장 높았다. 또한, 애견사료 2.5% 첨가 사료를 급여했을 때 흰점박이꽃무지와 장수풍뎅이의 유충기간은 약 67일과 116일로 기본 발효톱밥을 급여한 대조구에 비해 40일 이상 짧게 조사되었다. 따라서 가축사료는 부식성 식용곤충에 우수한 발육 효과를 나타내는 곤충 먹이원의 소재로서 활용될 수 있을 것으로 기대된다.
