Studies on cross infectivity of pebrine disease from Muga to Eri silkwormAbstract :
The causal organism of Pebrine disease Nosema antheraea was inoculated in second instar healthy eri silkwom larvae in ambient temperature and relative humidity. The data showed that pebrine disease caused significantly highest larval mortality in September-October (13.7%) followed by May-June (7.5%) and July-August (5.3%). Highest pupal mortality was recorded in July-August (13.2%) followed by May-June (9.6%). Significantly highest infection in adult moths was recorded in May-June (63.72%) followed by September-October (60.25%) and July-August (56.80%) which confirmed the cross infectivity of pebrine disease from muga to eri silkworm.
