Abstract

This study investigated the effect on body length, body width, body weight and mortality of larva white-spotted flower chafers(Protaetia brevitarsis seulensis) that the feeds as a secondary feed aloe, apple, banana, persimmon and sweet pumpkin being sold on the market. Weight of larvae increased the most in a sweet pumpkin 2,966 mg, and was followed by banana and persimmon. Weight increased in the aloe the control as the lowest in 2,179 ~ 2,127 mg. It fed the sweet pumpkin showed the highest cumulative increase of 240% in the body length then the persimmon was a cumulative increase of 232%. It fed the sweet pumpkin showed the highest cumulative increase of 254% in the body width and the lowest cumulative increase of 232% was the control. It fed the sweet pumpkin showed the highest cumulative increase of 240% in the body weight then the persimmon, banana, apple in order. Mortality showed most of the high mortality rate of 19.8% in the sweet pumpkin and apple and banana and the lowest mortality rate showed a mortality rate of 13.2% in the control. Although these results sweet pumpkin, persimmon and banana are expected higher utilization as a secondary feed, it should be reviewed in various feeding ways how to reduce the changes of the artificial breeding environment.

본 연구는 시중에 판매되고 있는 알로에, 사과, 바나나, 단감 및 단호박을 흰점박이꽃무지 유충의 보조사료로 급여에 따른 체장, 체폭, 체중 및 사망율 등을 알아보았다. 체중의 변화는 2,966 mg으로 단호박 급여구에서 가장 무거운 나타났으며, 다음으로 단감과 바나나 급여구로 나타났다. 가장 가벼운 체중의 보인 처리구는 알로에와 대조구로써 2,179 ~ 2,127 mg으로 나타났다. 체장 누적증가율은 단호박 급여구에서 가장 높은 누적 증가율인 240%를 보였으며, 다음으로 단감 급여구에서 232% 누적 증가율을 보였다. 체폭의 누적 증가율은 단호박 급여구에서 254%로 가장 높은 누적 증가율을 보였으며, 대조구에서는 111% 가장 낮은 누적 증가율이 나타났다. 체중 누적 증가율도 단호박 급여구에서 694%의 가장 높은 증가율을 나타났으며, 다음으로 단감, 바나나 및 사과 급여구 순으로 나타났다. 보조사료 급여에 따른 유충의 사망율은 단호박, 바나나 및 사과 급여구에서 가장 높은 19.8%의 사망율이 나타났으며, 가장 낮은 사망율은 대조구로 13.2%가 나타났다. 이러한 결과는 단호박, 단감과 바나나 등은 보조사료로써 활용성이 높을 것으로 기대되나, 인공사육 환경의 변화를 줄여 사망율을 줄이는 다양한 급이 방법 등의 방안 검토되어야 할 것이다.
