为摸清家蚕浓核病的蛋座传染规律,为家蛋病毒病的早期诊断实用化提供资料,本文对三龄將眠病蚕感染率与最終结茧率和最終产茧量间的相关性进行了探讨。试验证明病蚕混育率与最終结茧率和最終产茧量之间存在显著的负相关,相关系数絕对值均在0.90以上,平均病蚕感染率1%,最終结茧率减少10.6%左右。春、夏、中秋三季病蚕混育率与最終结茧率指数和最終产茧量的指数间的回归方程均在0.05水平上显著。据此認为当三龄將眠病蚕检出率达5%(包括5%)以上时,該批蚕已不具备継续饲养的价值,可作为家蚕浓核病早期诊断实用化的评定标准。
In order to find out the regular pattern of eggshell transmission in Bombyx mori and provide information for the early diagnosis and diagnosis of Egg virus disease, the correlation between infection rate, final cocoon yield and final cocoon production in the third instar was studied Discussed. The test proves that there is a significant negative correlation between the mixed rate of silkworm and the final cocoon yield and the final cocoon yield, the absolute value of the correlation coefficient is above 0.90, the average infection rate of disease and silkworm is 1% and the final cocoon yield is reduced by 10.6% about. The regression equations between the rate of silkworm rearing, the final cocooning index and the final cocoon yield of spring, summer and mid autumn were all significant at 0.05 level. Therefore, when the third instar was found to be more than 5% (including 5%), the batch of silkworms no longer have the value of continuous feeding, which can be used as the evaluation standard of the early diagnosis of the concentrated disease of silkworm .
