ABSTRACT
The cold storage duration and prerefrigeration period of cocoon, both caused notable impact on the fecundity and hatching per cent of eggs. The egg laying capability and hatching per cent decreased with increasing duration of refrigeration at all the prerefrigeration periods. The egg laying capability of moth (385 ± 2.05) and hatching per cent of egg (95.83 ± 1.16) was maximum in case of untreated cocoon while both, the hatchability (40.36 ± 3.26) and fecundity (305 ± 4.24) were minimum in 2 days prerefrigerated cocoon, refrigerated for 30 days. The cocoon of Bombyx mori race Nistari may safely be refrigerated for 10 days without causing any notable decline in the feecundity of moth and hatching per cent of the eggs. Thus, it may solve the problem of sericulture industry regarding the safe post ponement of the emergence of moth with good status of fecundity and hatchability.
ABSTRAK
Tempoh simpanan dalam keadaan sejuk dan pra-penyejukan kokum menunjukan kesan yang nyata daripada segi kefekunan dan peratus telur yang menetas. Keupayaan bertelur dan peratus yang menetas berkurangan dengan peningkatan tempoh penyejukan pada semua fasa pra-penyejukan. Keupayaan bertelur rama-rama (358 ± 2.05) dan peratus telur yang menetas (95.83 ± 1.16) adalah maksimum pada kokun kawalan. Manakala dalam kokun yang di pra-sejukan untuk 2 hari dan disejukan selama 30 hari, jumlah yang menetas (40.36 ± 3.26) dan kefekunan (305 ± 4.24) adalah minima. Kokun Bombyx mori boleh disejukan selama 10 hari tanpa menjejaskan kefekunan dan penetasan. Hasil ini akan dapat membantu industri serikultur dalam usaha mengawal penetasan telur rama-rama ini.
Key words: Bombyx mori, Refrigeration, Prerefrigeration, Fecundity, Hatchability.
