Certain Factors Affecting The Emergence of The Mulberry Silkworm Bombyx mori L. and The Fecundity of Male Ones

The aim of this study is to evaluate the effects of cold storage (7°C) and its exposure period (5, 10, 15 or 30 days) on some biological parameters of the mulberry silkworm Bombyx mori L. fresh cocoons, as well as, the effect of exposing the male moths to different temperature regimes (7, 18, 25 or 34°C) on the fertility and fecundity of mated females. The obtained results indicated that Bombyx mori L. could be safely stored as fresh cocoons up to 10 days at the temperature of 7°C. While, fecundity and fertility could be affected by exposing male moths to different temperature regimes.
