Abstract

The topical application of methoprene a kind of juvenile hormone(JH) on 4th instar larvae at 48th hour after ecdysis-3 , followed by insulin on 5th instar larvae and silkgland weights, cocoon weight and cocoon shell weight, and fecundity ; and significantly decreases percent of cocooning and moth emergence. After treatment with methoprene followed by insulin, cocoon weight increase by 17~20% and cocoon shell weights by 18~32% respectively.

누에에 유약호르몬 유사물질과 인슐린의 병용처리에 의한 효과를 알아보기 위하여 4령 탈피후 48시간째 methoprene을 처리하고, 5령 탈피후 72시간째 인슐린을 처리하여 시험한 결과 유충기간이 현저하게 길어지고 유충체중, 견사선무게, 전견중, 견층중, 증가하였으며, 발아비율과 산란성이 매우 향상되었다. 그리고 전견중은 암(기호)이 17%, 수(기호)가 20% 향상되었고 견층중은 암(기호)이 18%, 수(기호)가 32% 각각 더 무거워졌다.
