蜜蜂微孢子虫对蜜蜂越冬的影响

The Effects of Nosema p. on Bees Overwintering

蜜蜂微孢子虫病(microsporidian disease)病原为蜜蜂微孢子虫(Nosema p.),是一种分布广泛的成年蜂病,为重要的检疫性病害。对感染蜜蜂微孢子虫病的越冬蜂进行研究发现,蜜蜂微孢子虫感染率与蜜蜂越冬安全关系密切,各组合实验蜂群蜜蜂越冬死亡率均为差异极显著(U检验,P<0.01),即感染蜜蜂微孢子虫的蜂群,蜜蜂死亡率和饲料消耗量都明显高于对照组,且不同程度发生下痢症状。为蜜蜂微孢子虫的侵染机制研究提供理论数据,为进一步筛选功能基因奠定基础,从而推动我国特色蜜蜂产业健康快速发展。

Microsporidian disease of bees is a kind of widespread adult bees,disease and an important quarantinable disease whose pathogeny is Nosema p.. By investigating the overwintering bees that infected microsporidian disease, we found that Nosema p. was closely related to overwintering safety of bees. The results showed significant differences between various treatments by U test. The bee mortality and feed consumption of infected swarm were obviously higher than the control group, and produced symptoms of diarrhea.This research provided theoretical basis for infection mechanism of Nosema p. of bees, laid the foundation for further screening functional genes, and promoted characteristic bee industry healthy and rapid development in China.
