Abstract
Applicability of a new bamboo self mounting spiral mountages for handling the matured
silkworms with more ease and comparatively less labor was done from 2018 in Kolar and Chikkaballapur distrcits. The current study was planned to conduct field trials of the same at the farmers' rearing house in Kolar and Chikkaballapur districts to determine the
performance of a new spiral self mountage (2'x3.5') for effective cocooning in comparison to a self mounting plastic collapsible mountage (2'x3.5') and the regular bamboo mountage (Manual type). Both Cross Breed (CB) and Bivoltine Double Hybrid (Krishnaraja) silkworms were allowed to self-mount on a bamboo spiral mountage and the plastic collapsible mountage while the ripened silkworms were manually collected and distributed on the normal bamboo mountage. The cocoons harvested from spiral self mountage recorded maximum number of total cocoons (190.34, 223.13 cocoons/ mountage) and heavier cocoon weight (1.801, 2.005 g/cocoon), respectively for CB and Krishnaraja, compared to self mounting plastic collapsible mountage which rewarded least number of total cocoons (183.54, 186.57 cocoons/mountage) and lighter cocoons (1.680, 1.848 g/cocoon) in CB and Krishnaraja, respectively. The cocoon filament length (808.17 m/cocoon in CB and 1213.09 m/cocoon in Krishnaraja) and NBFL (723.20 in CB and 873.52 in Krishnaraja) reported maximum on spiral mountage reflecting its superiority. The economic parameters (cocoon and reeling parameters) of cocoons constructed on spiral mountage were comparable with that of regular bamboo mountage indicating that spiral mountages can be used for self mounting in both silkworms viz; CB and Krishnaraja for successful mounting along with significant in the reduced labour requirement.
