灰蜗牛微孢子虫感染家蚕的研究

Study of Fruticicola ravida Benson's Nosema Infection Silkworm

[目的]通过控制桑园中昆虫等生物的传染环境,达到控制家蚕微粒子病爆发。[方法]将桑园蜗牛镜检发现携带微粒子孢子的磨液添食家蚕后镜检,同时将家蚕微粒子孢子添食蜗牛后镜检。[结果]灰蜗牛携带的微孢子虫能够感染家蚕;家蚕微粒子孢子可以感染蜗牛。[结论]通过综合治理灰蜗牛,至少可以辅助控制和净化桑园环境。

[Objective] By controlling the infective environment of insect in mulberry field,the outbreak of silkworm＇s microsporidiosis was controled.[Method] Microscopic examination was conduced after silkworm was fed with the granding liquid contained pebrine of Fruticicola ravida Benso.Fruticicola ravida Benson was fed with pebrine spores.[Result]Fruticicola ravida Benso which carried microsporidia could infect the silkworm.At the same time,the silkworm＇s pebrine could infect Fruticicola ravida Benson.[Conclusion]The environment of mulberry field could be purified at least by the comprehensive treatment of Fruticicola ravida Benson.
