The aim of this study was to identify the optimal turning duration of Dandarawi hen incubated eggs on embryo mortality, hatchability, one-day chick weight and viability of chicks at 14 days of age. Collected eggs from Dandarawi hens at 36 weeks of age were stored for 7-d at 16°C and 75% RH and then were incubated for 21-d under standard incubation conditions using different turning durations. E...
Populations of Arboridia kermanshah Dlabola is increasing in Isfahan vineyards. In this study, some morphological characteristics of the immature stages, over wintering sites, number of generations per year, and seasonal population fluctuations of this pest were studied in vineyards in Isfahan Province. Eggs showed apparently four distinct embryonic developmental stages. At 25.8 ±2˚C, developme...
