Six mulberry cultivars and five rearing methods were evaluated in Department of Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, and Akola during 2006-2007. For the study PM X CSR2 race of mulberry silkworm, Bombyx mori L was used. The data thus obtained was analysed in FCRD design with cultivar as Factor ‘A’ and rearing method (magnetic field) as Factor ‘B’. The pooled results indicated that silkworm reared on S13 mulberry cultivar for 12 h magnetic field (S13M12) had significant effect on the activity of detoxifying enzyme in larva of mulberry silkworm and observed maximum enzymetic activity in midgut for Glutathione-s-transferase was 8.038 µM mg-1 protein, over normal method of rearing on mulberry cultivar V1 in zero hour magnetic field (V1M0) in which minimum enzymetic activity in midgut for Glutathione-s-transferase was estimated as 3.970 µM mg-1 protein. Thus, the study indicated that for minimizing the larval mortality rate in silkworm larvae they should be reared on S13 cultivar of mulberry in 300 gauss magnetic field for 12 h every day.
