Developmental variation of two different variety of Indian blow flies: Chrysomya megacephala (Fabricius, 1794) and Lucilia cuprina (Wiedemann, 1830) (Diptera: Calliphoridae) on dead Gallus gallus (Linnaeus, 1758)

The blow flies (Diptera: Calliphoridae) are among the most important flies for forensic dipterology. Thus, their immature stages are generally used for estimation of PMI and allied estimations. Therefore a study was conducted to investigate the effect of different seasonal variation on development in Gallus gallus Caracas, to analyze the seasonal variation of growth of two Indian blow flies for three seasons. Results for Chrysomya megacephala (Fabricius, 1794) and Lucilia cuprina (Wiedemann, 1830) showed that there was a significant variation in avg. length, and calculated biomass, width was insignificant among the three seasons of immature stages as [F (2, 33) = 3.440649166, p = 0.043932584], [F (2, 33) = 12.62242037, p = 0.00000849], and [F (2, 33) = 6.044256, p=0.0058] and as [F (2, 33) = 3.583334, p = 0.039057], [F (2, 33) = 5.825099, p= 0.006814] and [F (2, 33) = 1.094117, p = 0.346674] respectively.
