摘　　要：为探索桑褐斑病被害叶桑叶质量的变化,分别就该病叶片对4龄结茧率、虫蛹统一生命率,全茧量、茧层量、茧层率,产卵量、良卵率及实用孵化率的影响进行了试验。结果是全龄使用桑褐斑病被害叶(病情指数34.67%)相比全龄使用正常叶其4龄结茧率、虫蛹统一生命率、全茧量、茧层量、茧层率分别下降4.88、6.95、35.04、42.58、16.93个百分点,而产卵量、良卵率和实用孵化率却分别降低16.55、12.07和8.08个百分点。应重视和加强桑褐斑病的预测预报及防治工作。The influence of mulberry leaves infected by brown spot disease on 4th cocooning rate, pupa unified vital rate, cocoon weight, cocoon shell weight, cocoon layer ratio, egg laying amount, good egg rate and practical hatchability were investigated. The results showed that when mulberry leaves infected by brown spot disease were used, the 4th co- cooning rate, pupa unified vital rate, cocoon weight, cocoon shell weight and cocoon layer ratio would decreased by 4.88, 6.95, 35.04, 42.58, 16.93 percent respectively, and the egg laying amount, good egg rate and practical hatchability would decreased by 16.55, 12.07 and 8.08 percent respectively. It was indicated that the forecasting and prevention treatment of brown spot disease should be enhanced.
