Title

PERFORMANCES OF SIX IRANIAN SILKWORM HYBRIDS UNDER FOUR DIFFERENT ENVIRONMENTAL CONDITIONS

Pages

  358-363

Abstract

 The rearing performances of six different Iranian SILKWORM hybrids including 151x152, 151x110-32, 151x154, 103x104, 31x32 and 107x110 were investigated under standard as well as warm/humid, warm/dry and temperature fluctuating rearing conditions.Four climate treatments (each in three replications) were employed for 3rd molted larvae during two rearing seasons of spring and early autumn at 2004. The obtained results revealed significant effects of ENVIRONMENTAL CONDITIONs on inspecting traits.The hybrids of 151x152 showed the highest value of good cocoon percentage (76.26) significantly. Middle cocoon percentage was also lower in this hybrids (18.52) compare to others. Therefore the hybrid of 151x152 can be declared for high quality cocoon production. The values of larval mortality were higher in 103x104 (6.2%) and 31x32 (5.09%) and lower in 151x110-32 and 107x110 (2.85). The hybrids of 103xl04 and 31x32 also showed the highest pupal (13.13 and 12.96% respectively) and total mortalities (17.76 and 16.86% respectively). The fluctuation of temperature left no effect on cocoon weight reduction in hybrids of 151x 110-32, 31x32 and 107x 110, while caused great raise in cocoon weight of 103xl 04 hybrid. The weight of cocoon shell in hybrids of 151xllO-32 and 103xl04 did not fall because of temperature fluctuating rearing condition. In case of humidity enhancement, only the hybrid of 151x154 showed decrease of cocoon shell weight while this character showed no significant difference in humid and dry rearing condition for other hybrids.
