This study was aimed to determine the effect of vinclozolin on some enzym activities (glucose oxidase, catalase and xanthine oxidase) of Galleria mellonella (Lepidoptera: Pyralidae) which is an economically harmful species damaging the honeycomb in beekeeping. For experimental groups, the eggs obtained from stock were dropped into the mixed feed of vinclozolin at different doses (20, 40 and 60 ppm) and had the larvae fed with this feed.  However, at the same rate vinclozolin concentration, three different protein isolation methods were examined to determine maximum level in amount of protein in the homogenates. The total amount of protein was determined by Bradford method and the protein extracts were performed by SDS- PAGE analysis to obtain protein profile. The obtained extracts were used for enzyme activity analysis. In this study, activity of catalase enzyme, particularly effective in defense mechanism, activity of xanthine oxidase involved in nucleotide metabolism and activity of glucose oxidase in the metabolism of carbohydrates were measured. When compared with the results from control groups, the enzyme activities of the larvaes fed with the feed including 20, 40 and 60 ppm of vinclozolin were observed to vary or remain constant. Accordingly, glucose oxidase and catalase activities increased with the increase in amount of vinclozolin in the feed and the activity of xanthine oxidase remained stable.
