초록

뽕나무, 복분자, 블루베리의 전정 가지 대부분은 버려지고 있다. 따라서, 이들 버려지는 전정 가지를 활용하여 흰점박이꽃무지의 사육 가능성을 검토하기 위하여 발육 및 산란 특성을 조사하였다. 베리류 발효톱밥을 먹인 흰점박이꽃무지 유충 발육 기간은 뽕나무 발효톱밥 157.3일, 복분자 발효톱밥 130.3일, 블루베리 발효톱밥은 140일로 참나무 발효톱밥 169.3일에 비하여 짧아지고, 유충 무게가 증가하였으며, 생존율이 높았다. 흰점박이꽃무지 유충 집단 사육시 2.5 g 이상인 유충 비율은 3종류의 발효톱밥 모두 6주에서 8주사이에 60% 이상인 반면 같은 기간에 참나무 발효톱밥은 10% 이내였고, 10주가 지나야 2.5 g 이상인 유충의 비율이 높아졌다. 흰점박이꽃무지의 평균 산란수는 80개 이상으로 평균 산란기간은 9주정도 소요되었지만, 개체당 편차가 커서 유의차는 없었다. 3종류의 베리류 발효톱밥은 서로 혼합하여 사용해도 참나무 발효톱밥에 비해 유충 발육속도가 빠르고, 산란수는 차이가 없었다. 따라서, 흰점박이꽃무지를 사육하는데 있어서 베리류 발효톱밥이 참나무 발효톱밥에 비하여 효과적으로 추정된다.

Most pruning branches of mulberry, Korean raspberry (bokbunja), and blueberries are discarded without use. These discarded pruning branches were utilized as feed in the investigation of the development and oviposition characteristics of Protaetia brevitarsis with a focus on breeding possibilities. It was observed that the developmental period of P. brevitarsis larvae fed with berry fermented sawdust from mulberry, bokbunja, and blueberry was shortened to 157.3 130.3 days, and 140 days, respectively, compared to 169.3 days for those fed with oak fermented sawdust. The weight and survival rate of the larvae also increased. Under all three types of fermented sawdust feed, the percentage of larvae with weight ≧ 2.5 g during the group was over 60% between 6-8 weeks after hatching; however under oak fermented sawdust feed, it was within 10%, and the percentage only increased after 10 weeks. The average number of eggs laid per female was ≧ 80, with an average oviposition period of approximately 9 weeks; however, there was no significant difference owing to the large deviation per individual. Furthermore, mixed fermented sawdust from the three berries enhanced the growth rate of larvae, and there was no difference in the number of eggs laid compared to those fed with control oak fermented sawdust. Our study demonstrates berry fermentation sawdust is just as effective as oak fermentation sawdust in the breeding of P. brevitarsis.
