摘要：
The effects of UV-light on biochemical parameters of posterior silk gland of mulberry silkworm, Bombyx mori L. were investigated in two popular bivoltine hybrids, Jufang (Chinese) × Chenxin (Japanese) and Chenxin × Jufang fed an artificial diet. Larvae of the first day of fifth instar were used for the present investigation. The larvae were irradiated with 20 W of UV-light at the intensity of 40 cm above the larvae for one of three exposure times (30, 60 or 120 min) just before feeding. UV treatment produced no significant effects at 30 min. However, at 60 or 120 min there was a significant decrease in silk gland weight and the levels of total protein, free amino acids, RNA and carbohydrates. UV-light thus affects the biosynthetic activities of silk glands. © 2008 Taylor & Francis.
