Abstract
In this study, the occurrence of significant
seasonal diseases in newly developed silkworm crossbreeds MV1xS8 (Cavery gold)
and PMxFC2 (Mysore gold) was documented at the Department of Zoology, Jaysingpur
College, Jaysingpur, Kolhapur, Maharashtra, over the years 2021 and 2022,
across three seasons (summer, rainy, winter). The larvae of these crossbreeds
were assessed for illnesses such as Grasserie (BmNPV), Flacherie (BmIFV),
(BmDNV), and Muscardine (Beauveria bassiana). Throughout the study, we recorded
all three diseases. Over the course of two years, the average disease incidence
was found to be higher in PM x FC2 (26.93%) compared to MV1 x S8 (16.86%).
Flacherie and Grasserie showed higher incidence in PM x FC2 (11.61%, 7.63%),
and this variation was seasonal. Muscardine incidence was greater in both
crossbreeds during the winter season, at (7.95%, 7.66%). This study illustrates
the incidence of diseases in both crossbreeds, which impacts the production of
cocoons.
