Abstract

Two meridic diets, N4 and N6, containing pinto bean, wheat germ, soybean, whole milk and sucrose as main nutrients were developed for rearing Spodoptera frugiperda (Noctuidae) larvae. Six larval instars were observed when neonate larvae were individually raised on these diets in small petri-dishes (ø 50 × 10 mm, 19.6 ㎤) at 25℃ and 15:9 h (light:dark) photoperiod. The average pupation rate of 97.8% on the N4 diet was significantly higher than the rate of 85.6% on N6 diet. The emergence rates were 92.0% on N4 diet and 93.5% on N6 diet, with a non-significant difference. The larval periods were 17.9 and 17.7 days for females, and 18.7 and 18.5 days for males, for N4 and N6 diets, respectively, with non-significant differences between diets and sexes. The pupal periods on both diets were identical (11.1 days for females and 12.8 days for males), despite differences between sexes. The pupal weights of both sexes on N4 diet were identical with a value of 257 mg, whereas those on N6 diet were 256 and 263 mg for females and males, respectively, with a non-significant difference. The longevity of female adults that emerged on N6 diet was 13.8 days and longer than 8.6 days on N4 diet. The pre-oviposition periods were 5.0 and 4.2 days on the N4 and N6 diets, respectively, with a non-significant difference, however, the oviposition period of 6.5 days on N6 diet was longer than the period of 3.9 days on N4 diet. The effective fecundity on N6 diet was 1,392 eggs (maximum 1,776) and was higher than that of 942 eggs (maximum 1,694) on N4 diet, with a non-significant difference. The egg hatching rates on N4 and N6 diets were 79.2 and 79.8%, and egg periods were 3.0 and 2.9 days, respectively, with non-significant differences.

열대거세미나방(Spodoptera frugiperda)(밤나방과) 유충을 사육하기 위해 강낭콩과 맥아, 콩, 전지분유, 설탕을 주 영양분으로 구성한 두 종류(N4와 N6)의 반합성 인공사료를 개발하였다. 25℃와 광주기 15:9 h(명:암) 조건으로 페트리접시(지름 50 × 10 mm, 19.6 ㎤) 안에서 1령 유충을 각 사료로 개체별로 사육하였을 때, 6령 유충까지 관찰되었다. 용화율은 N4에서 평균 97.8%로 N6의 85.6%에 비해 유의하게 높았다. 번데기의 우화율은 각각 92.0과 93.5%로 유의한 차이는 없었다. 암컷 유충의 발육기간은 N4에서 17.9일, N6에서 17.7일이었고 수컷은 N4에서 18.7일, N6에서 18.5일이었는데, 사료 및 암수 사이에 차이는 없었다. 번데기 기간은 암컷이 11.1일, 수컷은 12.8일로 각 사료에서 동일하였는데, 암수 사이에는 유의한 차이가 있었다. 번데기 무게는 N4에서 257 mg로 암수가 동일하였고 N6 사료에서는 암컷이 256 mg, 수컷이 263 mg이었는데, 사료 및 암수 사이에 차이는 없었다. 각 사료로 자란 암컷 성충의 수명은 N4에서 8.6일에 비해 N6가 13.8일로 길었다. 산란전 기간은 N4에서 5.0일, N6에서 4.2일로 차이는 없었다. 산란기간은 N6사료에서 6.5일로 N4의 3.9일 보다 유의하게 길었다. 암컷당 유효 산란수는 N6에서 1,392개(최대 1,776개)로 N4사료에서의 942개(최대 1,694개)보다 많았으나, 사료 사이에 유의한 차이는 나타나지 않았다. N4와 N6 각각에서 알의 부화율은 79.2%와 79.8%이었고, 알 기간은 3.0일과 2.9일이었는데, 사료 사이에 유의한 차이는 없었다.
