摘要
为明确植物源物质东莨菪内酯对家蚕的生长发育和经济性状的影响,采用食下毒叶法测定东莨菪内酯不同浓度药液对家蚕生长发育和经济性状的影响。结果表明：用东莨菪内酯4000、2000、1000 mg/L药液分别处理家蚕,其出现摆头、吐液等轻微中毒症状。用东莨菪内酯125-4000 mg/L药液分别处理家蚕,至5龄的累计死亡率为24%-80%,延迟了家蚕各龄期的发育。东莨菪内酯各浓度药液处理家蚕后对其经济性状具有显著性影响,其全茧量、茧层量、化蛹率和蛹体重均显著低于对照处理,但对家蚕的茧层率不存在显著性影响。东莨菪内酯对家蚕具有慢性累积毒性,对其生长发育及经济性状造成显著性影响。
In order to clarify the effects of botanical compound scopoletin on the growth and development andeconomic characters of silkworm, Bombyx mori L. The different concentration of scopoletin were tested tosilkworm by food intake method. The results showed that they displayed symptoms like vomitive, distortedagainst B. mori, by treated of 4000, 2000 and 1000 mg/L. The cumulative mortalities were ranged from 24% to80%, with toxicity from 125 to 4000 mg/L treated silkworm to 5 instar, and the development of life stage weredelayed. There were significant effect of scopoletin on the economic characters of silkworm, and the wholecocoon weight, cocoon shell weight, pupation rate and pupal weight were significantly lower than the controltreatment, but the cocoon layer was not significant influence. Therefore, there were cumulative toxicity ofscopoletin on B. mori, if long-term high concentrations of feeding, otherwise it will cause a significant impact on the growth and economic traits.
