Abstract:
:Infection of the pebrine disease has been found to be highly virulent and harm the cocoon yield as well as characters of silkworm Anthereae mylitta. Therefore, an attempt was made to evaluate the impact of parasite Nosema species on the ecorace (Sukinda) of A. mylitta in respect of transovarial transmitted (T1), secondary infection (T2) and healthy silkworm (T3). In comparison to T3, the number of larval mortality was 16 and 11 in T1 and T2 respectively; whereas as number of pupal mortality was 6 and 5 in T1 and T2 respectivelyThe larval weight, number of moths emerged, number of eggs laid and percent hatchability were reduced in T1 and T2 in comparison to T3.The infected layings were high in T1 (51%) and T2 (42%) as against T3 (0%). Similarly, the infected moths were 34% in T1 and 15% in T2 as against 0 percent in T3. All the characteristics parameters of cocoon were reduced in T1 and T2 against T3. The study explains that there was no significant variation between T1 and T2 on different parameters of larva, pupa and cocoon characters.
