Abstract:
The study was carried out at Dipterian Research Laboratory Department of Entomology, Faculty of Crop Protection, Sindh Agriculture University Tandojam, on the impact of different photoperiods (8:16, 10:14, 24:0 and 0:24 Light & Darkness) were determined. The results were found that maximum emergence of female parasitoids 24.0±1.58 were noted on B. correcta at photoperiod 24:0 Light, followed by (10:14 L/D) 21.6±0.74, (8:16 L/D) 19.2±1.01, whereas the minimum % age of males and females 9.20±0.86, 15.4±0.92 pupae were obtained at photoperiod (0:24 Darkness), respectively. On the other hand, the D. ciliatus showed at photoperiod 24:0 Light highest ratios of male and female adults which were 15.4±0.92, and 20.0±0.70, while the lowest pupae emerged at 0:24 Darkness 6.00±0.70 and 10.8±0.80, respectively. The minimum emergence percentage was recorded at 0:24 Light for both sexes. The results further determined that D. giffardii prefer B. correcta as compared to D. ciliatus Furthermore, the analyzed data showed significant difference between different treatments (P<0.05).
