Effect of mite infested mulberry leaves on rearing performance and reeling parameters of silkworm, Bombyx mori L.

Abstract : Silkworms of SH6×NB4D2 hybrid were reared with mulberry leaves of selected varieties damaged by phytophagous mites to varied intensity during autumn season of 2010 and 2011 at CSR & TI, Pampore, Kashmir, India. Results revealed distinct differences in the silkworm biological and economic parameters viz., larval duration, larval weight, cocoon weight, shell weight, shell ratio, filament length and denier. Some more observations on the biological parameters shown concern as the mite damage in mulberry may increase disease susceptibility, feed requirement and labour besides the reduced yield and quality. Increased disease susceptibility, feed requirement and labour were observed when fed with the mite damaged mulberry leaves
