Why hatching is low in Aherua (June-July) and Bhodia crop (Aug-Sept) in muga silkworm?
The seed crops for Aherua and Bhodia crops falls under high temperature (35-38O C) which caused male sterility in 5th. Stage. This leads to false coupling in seed preparation and lay unfertilized eggs. Hence, hatching is poor. To avoid this, the rearing should be conducted in shady place/ areas and spinning of larvae should be allowed in cooler condition.
