摘要
蜜蜂微子虫病是世界性分布的成年蜜蜂传染病,对蜂群危害大。为寻找控制蜜蜂微孢子虫病的药物,对癸氧喹酯进行了的试验。将含癸氧喹酯2×10-6、1×10-5、5×10-5g/mL的蔗糖液,分别饲喂4天前就接种了东方蜜蜂微孢子虫(Nosema ceranae)的意蜂工蜂,连续喂药7d,再停药4天。试验结果表明,5×10-5g/mL的癸氧喹酯能显著降低工蜂的微孢子虫感染率(P<0.05),3种浓度的药物均能显著降低工蜂微孢子虫的感染程度(P<0.05);而药物对工蜂日均取食量、死亡率、中肠蛋白浓度、中肠葡萄糖苷酶相对酶活无显著影响(P>0.05)。
Nosema disease is a contagious disease of adult honeybees all over the world,which greatly impairs colony health.In order to test if decoquinate has inhibitive effect on Nosema infection in honeybees,sucrose solution(50%) containing 5×10-5,1×10-5,and 2×10-6g/mL of decoquinate were respectively fed to honeybee workers ad libitum,who were individually inoculated with Nosema ceranae spores four days ealier.Bees were fed with decoquinate for 7 days and then sucrose solution for another 4 days.The infection percentage was significantly(P<0.05)decreased after fed with 5×10-5g/mL of decoquinate,and the infection intensity of three treated groups significantly(P<0.05)declined too.The medication,however,didn't significantly(P>0.05)affect the amount of food consumed daily,mortality,protein concentration of the midgut,and the relative activity of α-glucosidase.
