摘要：
Three years' survey data on rearing of silkworm cross breed ('PM' x 'NB4D2') in different types of rearing houses of sericulturists in Tamil Nadu revealed that thatched roof mud house with cooler climatic conditions than tiled house and RCC building enchanced the larval duration and cocoon yield. Months with cooler atmospheric temperature also showed similar results when compared to hot months. Average values of maximum temperature of the months had a strong negative correlation with the larval duration and cocoon yield. Relative humidity reflected its influence on the larval duration only. The role of abiotic factors in modulating the larval duration and cocoon crop is discussed.
