Orius strigicollis의 증식 최적화 조건 탐색
초록
총채벌레류의 토착천적인 Orius strigicollis Poppius의 사육에 영향을 주는 부화율, 산란수 및 산란시기, 사육용기 당 암컷 성충의 밀도와 내적자연증가율을 광주기 16L:8D, 상대습도 10%, 온도 의 사육조건에서 조사하였다. 부화율과 알기간은 각각 88.5%, 5.7일이었다. 사육용기 당 산란수는 50-100개일 때에 우화율이 50.8%로 가장 좋았고, 새로 얻은 성충의 회수시기는 산란 후 17일이 적당하였다. 사육용기 당 암컷 성충의 밀도와 새로 얻은 성충의 수와의 관계는 Y= -10.7971n(X)+44.659(=0.7619)와 같았다. 사육실에서 대량으로 사육하는 경우 일세대 평균기간(T), 순번식율( )과 내적자연증가율( )은 각각 26.5일, 6.18과 0.0687이었다.
Determination of Optimum Conditions for Mass Rearing of Minute Pirate Bug, Orius strigicollis
Abstract
Orius strigicollis Poppies is an indigenous natural enemy of thrips pests in Korea To develop an efficient mass rearing system for Ο. strigicollis, effects of hatchability, egg numbers and egg harvesting time of Ο. strigicollis were measured in cylindrical cage (251 ㎤) under the conditions of photoperiod 16L : 8D, 10% RH and . The hatchability and developmental period of eggs were 88.5% and 5.7 days, respectively. The highest emergence rate (50.8%) was achieved when the number of eggs laid was ranged from 50 to 100 per arena. The proper harvesting time of newly produced adults was 17 days postoviposition. Relationship between the number of resulting adults per female and the number of female adults per arena was Y : -10.7971n (X) +44.659 (=0.7619). The generation time (T), the net reproductive rate ( ) and the intrinsic rate of natural increase ( ) were 26.5 days, 6.18 and 0.0687, respectively.
