Özet

© by PSP.The aim of this study was to determine the changes in cellular and humoral immunity of Uresiphita gilvata larvae fed with diets containing different amounts of protein and carbohydrate and infected with Bacillus thuringiensis subsp. kurstaki. In this context, it has been determined how diet conÂtents and infection affect superoxide dismutase (SOD), manganese superoxide dismutase (MnSOD), catalase (CAT), glutathione peroxidase (GSH-Px), phenoloxidase (PO) enzyme activities and total he-mocyte counts of larvae. For this purpose, four difÂferent diets were prepared by changing the amounts of protein and carbohydrate. Except for the control groups, other groups were infected with bacteria. In control and infected groups, superoxide dismutase and manganese superoxide dismutase enzymes showed the highest activity in the groups with the highest amount of protein. The catalase enzyme showed inhibition in all infected groups compared to control groups. As the amount ofprotein in the conÂtrol groups increased, the phenoloxidase enzyme was found to be activated. It was found that the numÂber of hemocytes decreased with infection (except H). Larvae exposed to infection and diet imbalance try to protect themselves with both cellular and huÂmoral defense to combat these negativities.
