| Abstract |
Fluorescent brightener-28 and Neemazal T/S (Neem) were used at different concentrations to increase the efficacy of AgseGV tested against Agrotis ipsilon (Hufn.) neonate larvae. F. brightener tested alone, did not result in any larval mortality wheres, the rate of larval mortality due to vinis was increased with increasing concentrations of F. brightener additive, in comparison with vinus alone treatment. The rate of enhancement of virus activity reached 1096.678 fold at 0.1% concentration. The calculated LT50 value decreased from 11.47 to 4.66 days at the concentration of 3.85xl07 capsule/ml diet when combined with 0.1% F. brightener. Neemazal T/S was added at three different concentrations (1,5 and 10, ppm) to AgseGV suspension and tested against A. ipsilon neonate larvae. Obtained results demonstrated that the Neem oil poorly enhanced the activity of AgseGV by reducing the LC50 value from 3.59xl07 capsule/ml diet for the virus alone treatment to only 7.11x106 capsule/ ml diet for the virus + Neem (at 10 ppm) treatment (potency = 5.057 fold). The calculated LT50 value decreased from 14.13 days for the virus alone treatment to 13.14, 10.56 and 7.2 days for the tested Neemazal concentrations, respectively. In conclusion, the combination of F. brightener or Neemazal T/S with the baculovirus, AgseGV may improve the activity of virus formulations.
