| 摘 要： | 分析了广东省蚕种繁殖试验所近 4 0年来家蚕原种微粒子病流行波动的规律性及广东省近1 0多年来杂交种微粒子病的流行情况。研究发现广东家蚕微粒子病在 80年代后的 1 0多年间 ,微粒子病发生出现较大的反复 ,平均发病率明显高于 80年代以前的水平。 80年代后的微粒子病发生流行有一定的季节周期性。广东省杂交种微粒子病发生、流行的频率与原种基本接近 ,但原种微粒子病流行和杂交种微粒子病流行趋势正好相反。影响微粒子病流行波动的因素有气候、地理方面的 ,也有经济和人为的因素。

| Abstract: | The prevalent laws for silkworm ( Bombyx mori L.) pebrine disease of parent seed produced in the Institute of Guangdong Silkworm Eggs Production nearly the past 40 years and the commercial eggs from all of the Guangdong silkworm eggs production farms in the past 10 years were studied in this report.The results showed that the occurring ratio of the pebrine disease changed remarkably during 1980s,and higher than that before 1980.There are some seasonal variations since 1980s.The occurring frequency of the pebrine disease of the commercial eggs was similar to that of the parent eggs,but the pebrine prevalent trends of the parent eggs is opposite to that of the commercial eggs.In this way,the weather conditions,geographical position,economic and artificial activity are all the factors which influences the pebrine disease prevelence. |
