| Abstract | ||||
| Bombyx mori L. rearers usually face the problem of non-synchronized egg hatching and subsequent low hatchability rate as they do not have equipment to control optimum temperature, humidity and light intensity. The experiment depends on focusing LED lighting on eggs with adjustment of temperature and humidity till hatching. The effect of continuous LED lighting on B. mori, on two hybrids (Egyptian and Bulgarian) embryos, for different periods (24, 72, 120, 168, 216 hrs.) was studied. The changes in total proteins, carbohydrates and lipids (mg/g egg weight) titers were estimated colorimetricaly. The results showed that a gradual improvement in egg hatchability percentages with shortage in incubation period for treated eggs compared with control. The best results were achieved under the continuous LED lighting till hatching (216 hrs.). The embryos respond to LED exposure by modulating metabolism to adapt lighting stress for both the two hybrids. Also, response of embryos depends on the hybrid origin. It may be recommended to use LED light at the last stage of B. mori, embryogenesis as a non-emitting heat light source to enhance and unify hatchability and shorten incubation period. | ||||
