【摘要】 本文报道了以不同大小沙粒（Φ120～210μm，210～420μm，420～600μm，600～850μm）作侵染介质，贮存在5℃下349天的S.carpocapsaeA24侵染期线虫和新培养的S.carpocapsaeA24浸染期线虫对大错螟（Galleriamellonella）幼虫的侵染力比较结果。实验表明：以120～210μm或210～420μm沙粒作侵染介质，新培养的A24侵染力都分别显著高于贮存349天的线虫的侵染力，对于420～600μm或600～850μm沙粒作浸染介质，两者均没有显著差异。而无论新培养的A24或低温贮存349天的A24，以Φ120～210μm沙粒作侵染介质下线虫的浸染力与以Φ210～420μm沙粒作浸染介质的线虫侵染力没有显著差异，但都分别高于用Φ420～600μm和Φ600～850μm沙粒作侵染介质的线虫侵染力。更多还原

【Abstract】 Infectivity of S. Carpocapsae A24 that was fresh (had not ever stored) and stored in atta-pulgite at 5℃ for 349 days in different fractions of sand was measured by the number of nema-todes established in Galleria mellonella larvae. The mean number of nematodes estublished in Galleriamellonella larvae was significantly higher in particles of Φ≤420 μm (Φ120~210 μm, 210~ 420μm) than that in particles of Φ>420 μm (Φ420~ 600 μm, 600~ 850 μm). The mean unmberof nematodes stored in attapulgite at 5℃ for 349 days was significantly lower in the sand particlesof same size of Φ120~210 um and Φ210~ 420 μm.更多还原
