Bionomical Characteristics of Luciola lateralis (Coleoptera: Lampyridae) in Mass Breeding

This study was performed to investigate the bionomical characteristics of Luciola lateralis in Korea. Imago's longevity of female was $17.5{\pm}0.7$ and male was $20.6{\pm}1.0$ days at $23^{\circ}C$, R.H. 80%, and significant difference was not occurred in breeding density. Pre-oviposition period was a pair $2.8{\pm}1.5$, two pairs $2.5{\pm}1.5$, three pairs $1.7{\pm}0.7$, four pairs $1.3{\pm}0.5$ days and pre-oviposition period was shorten in higher breeding density. The mean of laying eggs was $248.9{\pm}80.7$, was not related breeding density. Daily oviposition rate was 1st day 20.8%, 2nd 17.3%, 3rd 14.3%, 4th 12.7%, 5th 7.0%, the rate was highest in 1st day and gradually reduced. Egg period was $21.8{\pm}0.7$ days and hatchability was $95.5{\pm}4.8%$. Larval instar was identified the 9th instar, the evidence was able to its skin and marking pattern. Larval period of each instar was 1st $1.0{\pm}0.1$, 2nd $3.3{\pm}0.2$, 3rd $10.2{\pm}1.0$, 4th $6.8{\pm}0.5$, 5th $6.9{\pm}2.0$, 6th $15.4{\pm}4.1$, 7th $18.3{\pm}5.9$, 8th $25.8{\pm}8.7$, 9th $31.2{\pm}13.2$ days. Matured 9th larva was made of cocoon during $2.8{\pm}0.8$ days and pre-pupal, pupal period was $4.6{\pm}0.9$, $5.6{\pm}0.7$ days. Imago was made hard hind wing during $3.8{\pm}0.4$ days in cocoon and come out.

애반딧불이(딱정벌레목: 반딧불이과)의 생육 특성

우리나라에서 서식하는 애반딧불이의 생육 특성을 조사한 결과, $23^{\circ}C$, R.H. 80%에서 사육에서 성충 수명은 암컷이 $17.5{\pm}0.7$일, 수컷이 $20.6{\pm}1.0$일으로 수컷이 다소 높았으나, 사육밀도별 유의차는 없었다. 성충 출현 후 최초 산란일은 1쌍 $2.8{\pm}1.5$일, 2쌍 $2.5{\pm}1.5$일, 3쌍 $1.7{\pm}0.7$일, 4쌍 $1.3{\pm}0.5$일로 사육 밀도가 증가함에 따라 산란전기가 짧아졌다. 산란수는 평균 $248.9{\pm}80.7$개를 산란하며, 사육밀도와는 유의성이 없었다. 일별 산란은 산란 시작 1일째가 20.8%, 2일째 17.3%, 3일째 14.3%, 4일째 12.7%, 5일째 7.0%의 순으로 산란 시작 1일째가 가장 높고 시간이 경과함에 따라 점차 낮아졌다. 난기간은 $21.8{\pm}0.7$일이고, 부화율은 $95.5{\pm}4.8%$이었다. 유충 령기 구분은 탈피각과 유충반문으로 조사한 바 9령으로 확인되었고 1령 $1.0{\pm}0.1$일, 2령 $3.3{\pm}0.2$일, 3령 $10.2{\pm}1.0$일, 4령 $6.8{\pm}0.5$일, 5령 $6.9{\pm}2.0$일, 6령 $15.4{\pm}4.1$일, 7령 $18.3{\pm}5.9$일, 8령 $25.8{\pm}8.7$일, 9령 $31.2{\pm}13.2$일이었다. 성숙한 9령 유충은 $2.8{\pm}0.8$일 동안 용실을 만들고, 전용기간과 용기간은 $4.6{\pm}0.9$일과 $5.6{\pm}0.7$일이었으며, 성충이 된 후 약 $3.8{\pm}0.4$일 동안 뒷날개를 굳힌 후 용실을 뚫고 탈출하였다
