摘　　要：环境中微粒子虫孢子的存在是造成蚕种微粒子病发生的重要因素。为了解饲养环境中微粒子虫孢子情况,我们于2016、2017年进行了环境中微粒子虫孢子情况调查。通过调查发现,普通蚕饲养区微粒子检出率明显高于原蚕饲养区,而且秋期检出率为最高;普通蚕饲养区的桑树害虫和迟眠蚕、病死蚕中微粒子检出率显著偏高;原蚕区的桑树害虫检出率也明显偏高;个别蚕区养蚕环境微粒子虫孢子污染严重。Pebrine Spores（Nosema spores）existed in the environment are important factors causing the silkworm pebrine disease. In order to understand the situation of Nosema spores in the silkworm rearing environment, we investigated the spores occurrence in the environment in year 2016 and 2017. The authors found that the microspore detected rate in silkworm rearing areas for cocoon production was significantly higher than that of parent silkworm rearing areas, and the autumn raring season was of the highest. The microspore detected rate from the samples of mulberry pests, and late molted silkworm larvae, diseased or dead silkworm in the silkworm rearing areas for cocoon production were all very high. The microspore detected rate from the samples of mulberry pests from parent silkworm rearing areas was also higher than expected. Particularly there was severe pollution of Nosema spores in a few silkworm rearing areas.
