Abstract

The present experiment was conducted in the laboratory of Entomology, Dr. PDKV Akola, during August 2017-18 and 2018-19. The nine main treatments were the exposure of Corcyra larvae to the magnetic field for 0 hrs, 24 hrs, 12 hrs, 6 hrs, 3 hrs, 2 hrs, 1½ hrs, 1 hrs and ½ hrs duration and four sub treatments were rearing of the larvae on diet CSH-35 (D1), Maldandi 35-1 (D2), Swati (D3) and CSH-9 (D4) variety of sorghum. Observations were recorded based on pooled data, after 16 days and 24 days on weight and length of Corcyra larvae. The result indicates that, rearing of Corcyra in the magnetic field for 12 hrs recorded maximum weight and length 14.91 mg and 12.27 mm and after 24 days on maximum weight and length of Corcyra larvae was observed in 46.31 mg and 16.41 mm in magnetic field treatment for 12 hrs.

Conclusion

From the present study concluded the exposure of Corcyra cephalonica in magnetic field for reared ½ hrs, 1 hrs and 24 hrs period had negative impact on growth and development of larvae. Exposure of Corcyra cephalonica to magnetic field for 12 hrs had positive impact on larval weight and length. Amongst different diets tested the best diet for the growth and development of Corcyra was observed to be sorghum variety Maldandi 35-1 (D2). So this variety can be recommended for commercial rearing of Corcyra. The interaction effect of magnetic field 12 hrs and Maldandi 35-1 (D2) diet had good growth of Corcyra larvae as compare to non magnetic field. Exposure of larvae for 12 hrs had positive impact on biological parameter can be used for mass multiplication of Corcyra and that for 24 hrs can be used in management of Corcyra under store condition.
