Testosterone Propionate가 가잠의 실용형질에 미치는 영향 다화성계통의 1종인 Pure Mysore 품종에 대한 testosterone propionate(TP)의 농도별 (1, 5, 10$\mu$g/ml) 투여효과를 조사하였다. TP의 처리는 유충 3, 4, 5령의 36시간째 투여구(처리-1), 4, 5령의 48시간째 투여구(처리-2) 및 5령 72시간째 투여구(처리-3)의 3개 시험구를 설정하여 농도별로 피부에 침투하였다. 실험 결과 모든 시험구에서 TP 처리는 산란성에 증대효과를 보였으나, 화용비율 및 발아비율은 대조구에 비해 떨어지고 있었다.
Effects of topical application with 1, 5 and 10 ${\mu}$g/ml testosterone on the precocooning and post cocooning traits of the polyvoltine. Pure Mysore breed of silkworm were studied. Each concentration was treated independently at 36th to III, IV and V instar larvae(Treatment-1), at 48th to IV and V instar larvae(Treatment-2_ and at 72th to V instar larvae(Treatment-3). The repeated application with each concentration of testosterone propionate in treatment, and 2 larvae or single application in treatment 3 variously affected the precocooning and post cocooning traits. Repeated applications of all doses of testosterone propionate(Treatment-1) and single application of 1 & 5 ${\mu}$g of the chemical(Treatment-3) increase the fecundity and decrease the percentage of cocooning and moth emergence.
