Impact of High Temperature (36+1oC) and Low Humidity (35+5%) on Overall Performance of Bombyx mori L.

Vikash Kumar, Dr. Bhrigu Nath

Abstract: The impact of 36+1oC temperature with 35+5% humidity on rearing, breeding and economic traits of Bombyx mori L. was observed during present research work for each parameter of each breed under study. On the basis of average EI of all parameters it became evident that four breed showed good suitability during 36+1oC temperature with 35+5% humidity because their average EI remained more than 50. Among all breeds evaluated during above stated climatic conditions SK6 (57.46), SH6 (57.27), SK1 (56.16) and CSR4 (52.31) acquired 1st, 2nd, 3rd and 4th rank respectively, on the basis of average EI. Thus, it became evident that 36+1oC temperature with 35+5% humidity remain better for these breeds as compared to other breeds of Bombyx mori L. undertaken during present study. It was observed that SK6 breed shows good results during said climatic condition because this breed acquired 1st rank on the basis of average results of all parameters, evaluated during present research work. On the basis of average EI, it can be said that 36+1oC temperature with 35+5% humidity not remain suitable for rearing of most of the bivoltine breeds of Bombyx mori L. Thus, it became evident from overall evaluation that SK6 breed can tolerate high temperature with low humidity as well as three other breeds such as SH6, SK1 and CSR4 also shows tolerance upto some extent. So, bivoltine breeds of mulberry silkworm such as SK6, SH6, SK1 and CSR4 can be reared even at extremes of temperature and humidity conditions.
