Abstract
Four monovoltine lines were utilized in a half diallel crosses in the present study. The six hybrids resulted were coded as (1x2), (1x3), (1x4), (2x3), (2x4) and (3x4).
                It was concluded that the hybrid (1x2) was the best for most studied economic traits such as cocoon weight, cocoon shell weight, pupal weight and larval duration. This hybrid was also better for cocoon hatchability percentage. The hybrid (1x3) was better for cocoon weight, cocoon shell ratio and egg fertility. While hybrid (2x3) was the best for egg traits such as fecundity, fertility and hatchability percentage over both the better and mid parents.
