[Preliminary study on anti-baculovirus mechanism of feeding housefly larvae (Musca domestia) and population infection model of outbreaking epidemic disease of shrimp (Panaeus chinensis)].
Based on indoors individual infection and outdoor population infection of shrimp, population infection model was established and anti-baculovirus mechanism of housefly larvae was analyzed. The results showed that 50% death time of the shrimps feeding with housefly larval reasonably was prolonged 3-5 times compared with the control group. Prophenoloxidase system of prawns was activated while feeding shrimps with housefly larval 7-10 days before infection by baculovirus, and prophenoloxidase activity was 3 times higher than the control group. The establishment of population infection model illustrated clearly important role of housefly larvae in improving the immunity of shrimps from baculovirus.
