Potential of turmeric extract and its chemical fractions were evaluated to control the infestation of Bactrocera zonata peach fruit fly in a mortality-based bioassay. The turmeric extract (TE) was taken on Soxhelt's extraction apparatus and chemically fractioned by thin layer followed by column chromatography into 6 fractions (F1 ...F6). Fifty pairs of the flies were fed in cages with 250 and 500 ppm TE and its fractions separately for 20 days along with flies fed on untreated diet to serve as control. The toxicity of TE and each of its fractions was evaluated by calculating percent mortality of fly population after every 5th day in 4 consecutive intervals. Mortality of fly population was observed to be positively correlated with increasing concentrations of TE and its fractions in diet. The mortality of flies fed at 250 and 500 ppm TE was significantly higher at 44.17 and 66.33% compared to 28.88% in control. Percent mortality was much higher in case of flies fed with fractions F1, F3 and F6 i.e. 72.22, 50.00 and 48.76 respectively. Maximum rise of mortality was observed at the end of 3rd interval; in case of flies fed at 500 ppm TE, 52.45 percent mortality was observed at the end of 3rd interval; highest mortality was caused by fraction F1, 51.39% in case of flies fed at 250 ppm and 70.37% in case of those fed at 500 ppm
