(Hymenoptera: Ichneumonidae), which is a soliterendoparasitoid, is investigated. Totally six diets were used and these diets wereproduced by increasing and decreasing with a ratio of 50%, omitting honey in controldiet. Same processes were done for honeycomb. The diet without honeycombdecreased the total adult and female ratios when compared with control and otherdiets. In this diet female emergence ratio is 38.55%. On the other hand in diet whichincluded 50% more honey than the control group female emergence appears to be77.72%. This is the maximum value throughout the experiment. Honey didn?t have asignificant effect on adult female development time however, increase of honeycombwith a ratio of 50% significantly decreased this time.Key Words: Pimpla turionellae, Galleria mellonella, sex ratio
