Abstract

Egg-forming and preservation methods for the indoor-rearing system of the emma field cricket, Teleogryllus emma, were investigated. The oviposition preference experiment on different mats, soil(natural oviposition mat) and $oasis^{\circledR}$(artificial oviposition mat), showed that T. emma preferred to oviposit on the $oasis^{\circledR}$. On the other hand, $oasis^{\circledR}$ had more inactive number of eggs laid per female and hatchability than another. However, the number of eggs laid per female and hatchability within 50 days after emergence were better than soil. The experiment on the hatching of the eggs showed that eggs could be stocked at $10^{\circ}C$ for 40 days with 14 day pre-period after laying, representing $62.1\%$ hatchability, when considering generation shortening. On the other hand, When it had been kept in cold storage for 90 days at $7.5^{\circ}C$ with 14 day pre-period after laying it, appeared to be the most suitable for long period-storage method by hatchability $65.1\%$.

왕귀뚜라미 대량 사육시 요구되는 실내 채란법 개발을 위하여 인공산란매트 선발과 알 저장조건을 조사하였다. 인공산란매트로서 수분 유지능력이 우수한 원예용 오아시스$^{\circledR}$가 천연의 매트인 흙에 비해 산란선호성이 월등히 우수하였다. 한편 인공산란매트로서 원예용 오아시스$^{\circledR}$는 흙에 비해 총산란수 및 부화율이 다소 저조하였으나 산란이 집중적으로 이루어지는 실용 산란기간(성충화 후 50일이내)의 산란수 및 부화율은 오히려 흙에 비해 우수하였다. 알의 저장조건은 산란 후 14일째, $10^{\circ}C$에 40일간 냉장한 구가 부화율 $62.1\%$로 세대단축 등을 고려할 때 단기저장으로 가장 적합한 것으로 판단되었으며, 산란 후 14일째, $7.5^{\circ}C$에 90일 냉장했을 때 부화율 $65.1\%$로 장기저장법으로 가장 적합한 것으로 나타났다.
