| 摘 要： | 探讨家蚕不同饲料营养与抗性生理的关系对家蚕的病理生理及蚕病预防研究具有重要意义。自4龄起蚕开始用柘树叶和桑叶分组饲养,调查家蚕的生长发育状况,并连续10 d分别检测蚕体内与抗性相关的酶活性。结果表明:柘叶饲养组不仅蚕体重和体长的增长小于桑叶饲养组,而且上蔟率、结茧率、全茧量及茧层量均显著低于桑叶组;柘叶饲养组蚕体内的碱性磷酸酯酶、乙酰胆碱酯酶及羧酸酯酶活性平均值分别为0.070 8、14.129 0、632.557 1 U/mL,桑叶饲养组蚕体内的碱性磷酸酯酶、乙酰胆碱酯酶和羧酸酯酶的活性平均值分别为0.076 4、15.189 0、628.055 1 U/mL,与桑叶饲养组相比,柘叶饲养组蚕体内的碱性磷酸酯酶和乙酰胆碱酯酶活性显著降低,而羧酸脂酶的活性显著提高(P<0.05)。由此认为,家蚕采用拓叶饲养会在一定程度上影响蚕体的生理代谢,降低蚕体对不良环境的抵抗能力。

| Abstract: | Effects of two kinds of forage leaves,namely tricuspid cudrania leaves Cudrania tricuspidata(Carr.) Bur.] and mulberry leaves(Morus alba),on growth and metabolic enzymes of silkworm(Bombyx mori) were surveyed in the study.Silkworms were reared with mulberry leaves till the 4th newly exuviated larvae,after which tricuspid cudrania leaves were used.Activity of enzymes related to silkworm's resistance were measured daily till the 10th day.Results showed that mean body weight and mean body length of the tricus... |
