　　On Feb. 23-24, 2006, Mianyang agricultural sector held training classes for local sericultural technicians on silkworm pebline disease prevention and treatment. Technicians would be imparted training periodically, said the sponsor.

Pebrine disease is a devastating infection that causes massive mortality and losses in silkworm colonies that can lead to significant economic losses. As production is usually relatively small-scale the occurrence of this disease can effectively wipe out a worker’s yield to zero.

Last year, Weicheng Silkworm Egg Producing Mill in Nanchong produced 76510 boxes of silkworm eggs, among them, eggs with pebrine disease accounted for 43.91 per cent of total production volume. The eligible rate was only 56.1 per cent.
