Abstract

This study was evaluated to increase the production efficiency of Gryllus bimaculatus De Geer, which are recently increasing attention as industrial insects in Korea. In this study, the hatching rate and larval period were investigated along with temperature and humidity, as well as the survival rate and ovipositional temperatures along with rearing density. The optimum relative humidity for hatching was highest at 90%, which shows the hatching rate of 90%. The highest hatching rate was 98.3% at 20℃. The hatching period was shortest at 35℃ incubation, which shows 7.1 days in average. The survival rate at 3,000-20,000 individuals in the breeding container was 34-18% after rearing for 35 days. In the effect test of feeding vegetables, the survival rate was 1.8 times and the biomass weight 2.5 times higher than that of normal individuals respectively. The number of laying eggs by temperature was highest at 25℃, which shows 1,710 eggs after reading for 30 days.

초록

본 연구는 최근 산업곤충으로 주목받고 있는 쌍별귀뚜라미의 생산 효율 증대를 위해 수행되었다. 이를 위해 온도, 습도에 따른 부화율 및 부 화 기간을 비롯하여 사육 밀도에 따른 생존율 및 산란 온도에 따른 산란수를 조사하였다. 적정 부화 상대습도는 90% 조건에서 부화율 90%를 보여 가장 높았다. 온도별 부화율 조사결과 20℃에서 98.3%로 가장 높았다. 또한, 온도별 부화 35℃조건에서 7.1일로 가장 짧게 나타났다. 또한 사육 용기에 3,000~20,000개체를 투입하여 35일간 조사한 밀도별 생존율은 34~18%였다. 쌍별귀뚜라미의 먹이에 채소 급여가 성장에 미치는 특성 을 조사한 결과 생존율은 1.8배, 생체중량은 2.5배 높게 나타났다. 온도별 산란수 조사결과 25℃ 조건에서 30일 후 1,710개로 가장 높았다.
