Enhanced activity of agrotis segetum (HUF.)(Lepidoptera: noctuidae) granulovirus by boric acid additive in the laboratory and semi field condition [electronic resource].

Includes references.

The enhancement of Agrolis segetum granulovims (AgseGV) activity using the boric acid additive was investigated. The bioassay results revealed that the vims suspension contained 0.5,1, 3 and 5% boric acid increased the monaliry rate of A. ipsilon 2 nd (5- day old) larvae as compared with the vims alone. This rate of mortality increased with illcrensing concentration of boric acid added to the virus. The LC:,o value of the 2nd. instar larvae was reduced 10 fold by 3% boric acid + GV. Funhenllore, the time required for AgseGV to kill larvae was significantly reduced by boric acid.
