Abstract: The particular study was conducted to examine the preference of D. giffardii on the pupae of B. zonata (Saunders) and B. cucurbitae (Coquillett) at different temperatures. The experiment was conducted at Dipterian Research Laboratory, Department of Entomology, Faculty of Crop Protection, and Sindh Agriculture University Tandojam during 2015-2016. The Research was carried out at five constant temperatures (15oC, 20oC, 25oC, 30oC and 35oC). The results revealed that the maximum emergence percentage of parasitoid female adults was founded on B. zonata pupae at 25oC 22.6±0.82, followed by 20oC 18.0±0.64, 30oC 17.4±0.51, 35oC 14.8±0.97, whereas, minimum emergence was observed at 15oC 11.8± 0.38. For male adults, the maximum emergence percentage was 18.0±0.71 at 25oC and the minimum emergence was recorded at 15oC 8.80±0.59. The B. cucurbitae showed the highest emergence percentage for both, female and male adults’ at 25oC which was 19.6±1.17 and 15.4±0.82 respectively. The minimum emergence percentage was recorded at 15oC for both sexes. The results determined that D. giffardii prefer B. zonata as compared to B. cucurbitae. Furthermore, the analyzed data showed significant difference between different treatments (P<0.05). On the basis of above results it can be concluded that the optimum temperature for mass rearing of D. giffardii is 25oC while the more suitable host is B. zonata.
