【摘要】 本试验通过用不同剂量的家蚕微粒子虫孢子感染5龄期家蚕幼虫,获得微粒子病毒蛾,并将这些有病蛾混入数量不等的未感染母蛾中,进行微粒子病检出率的测试,结果表明:在样本容量为180蛾时,检出率仍可达到现行生产要求的100%。更多还原

【Abstract】 Nosema bombycis spores were injected per os to fifth instar silkworm four times with different dose,the mother moth examination was carried out ,and also these pebrine infect-ed moths were mixed with uninfected moths and the detection of the spored was done to check the sensitivity of detection by mass method,results revealed that the sensitivity of detecting the infected moth was fool proof even among180moths.更多还原
