Abstract

The embryonic and postembryonic developments of Pierodorus hybneri Linnaeus were observed in 5 different rearing cages such as A (Cylindrical, 10 cm in diameter, height of 4 cm), B (Cylindrical, 14.5 cm in diameter, height of 2.8 cm), C (Rectangle, 6.5 by 6.5 cm in $length{\times}breadth$, height of 10 cm), D (Cylindrical, 9 cm in bottom diameter, 11.5 cm in upper diameter, height of 10.8 cm) and E (Cylindrical, 15 cm in diameter, height of 7.5 cm) containing soybean and peanut seeds as feeding food, and sponge-water container under laboratory condition of $24^{\circ}C$ and 16L:8D. Egg duration was 6 days regardless of rearing cages. Hatchability ranged from 63 to 80% with the highest in B (14.5 cm in diameter, 2.8 cm in height) rearing cage. Instar duration was longer from 5 days in 1st instar to about 11 days in 5th instar. Nymphal duration showed 35 to 36 days with'3ut significant difference in rearing cages. Percent emergence was in range from 65 to 82% with the highest in B rearing cage. Adult longevity was 35 to 83 days for male, and 32 to 79 days for female, and was the longest in B rearing cage. Total number of eggs laid by female adult was in range from 38 to 86 with significant difference in rearing cages, and was the most in B rearing cage. Accordingly, the reproductive rate of P. hybneri for 1 generation was within 17 to 56 times, and was the highest in B rearing cage. Therefore, it could be concluded that B cage is most suitable for stable rearing of P. hybneri under laboratory condition.

규격이 다른 5가지 사육용기, A용기 (원통형, 직경 10 cm, 높이 4 cm), B용기 (원통형, 지름 14.5 cm, 높이 2.8 cm), C용기 (사각통, 가로${\times}$세로 : $6.5{\times}6.5cm$, 높이 10 cm), D용기 (원통형, 밑지름 9 cm, 밑지름 11.5 cm,높이 10.8 cm), E용기 (원통형, 직경 15 cm, 높이 7.5 cm)에 두류종자 (대두+땅 콩종자) 및 스폰지급수물을 제공하여 $24^{\circ}C$, 16L:8D 실내조건에서 가로줄노린재의 부화율, 우화율 및 산란수를 조사하여 증식율을 구하였다. 난기간은 사육용기에 관계없이 6일 이었다. 부화율은 $63{\sim}80%$로 B용기에서 가장 높았다. 영기별 발육기간은 1령에서 5일, 5령에서 11일로 영기가 증가할수록 현저히 증가하였다. 약충기간은 $35{\sim}36$일로 사육용기에 따른 현저한 차이는 없었다. 우화을은 $65{\sim}82%$로 B용기에서 가장 높았으며, 다음은 A용기 였다. 성충수명은 수컷에서 $35{\sim}83$일, 암컷에서 $32{\sim}79$일 이었고, 성별에 관계없이 B용기에서 가장 길었다. 암컷의 산란수는 $38{\sim}86$개로 사육용기에 따라 현저한 차이가 있었으며, B용기에서 가장 많았고, E용기에서 가장 적었다. 따라서 가로줄노린재의 1세대 증식율은 약 $17{\sim}56$배로 사육용기에 따른 현저한 차이와 함께 B용기에서 가장 높았다. 그러므로 실내에서 가로줄노린재를 가장 안정적으로 사육하기 위해선 B용기를 이용하는 것이 가장 효과적인 것으로 나타났다.
