EFFICACY OF SODIUM HYPOCHLORITE IN CONTROLLING BACTERIAL INFECTIONS IN FIFTH INSTAR LARVAE OF ANTHEREAE MYLITTA DRURY (DABA TV)

Bacterial diseases are highly virulent and cause significant crop loss in Anthereae mylittadrury (Daba TV).Therefore an attempt has been made to evaluate the efficient concentration of sodium hypochlorite in controlling bacterial infection through studies on mortality, Total haemocytes, Protein carbonyl content, Alanine transaminase, Aspartate transaminase in the fifth in star larvae. Results reveal that supplementation of 0.05% sodium hypochlorite concentration had significantly reduced the mortality rate due to bacterial infections. In comparison with the control (14788±123), the haemocyte count in 0.05% sodium hypochlorite supplemented larvae were recorded low as14125±146 whereas 0.1% and 0.01%concentration supplementation resulted in an increase of 15025±158 and 14965±185 haemocytes. In comparison with the control results also show that protein carbonyl content was doubled with 0.05% supplementation whereas an increase of 33.3% and 16.6% was recorded with 0.01% and 0.1% respectively. Alanine aminotransferase had shown significant increase of 138.7% with 0.05% sodium hypochlorite supplementation followed by 39% increase with 0.01% concentration in its activity. Supplementation with 0.1% did not show much variation in Alanine aminotransferase from the control. Aspartate aminotransferase activity levels found increased by 106.2% in fifth in star larvae supplemented with 0.05% sodium hypochlorite whereas 30.2% and 21.75% increase was recorded with 0.01%, 0.1% respectively. Based on the results obtained from present study 0.05% sodium hypochlorite is found efficient in controlling bacterial infections in Anthereae mylitta drury (Daba TV).
