| Popis: | Objective: To evaluate the deterrence of oviposition potentiality of a novel phytopesticide PONNEEM against the generalist herbivorous lepidopteran insect pests Helicoverpa armigera and Spodoptera litura. Methods: Different phytopesticidal formulations were prepared at different ratio to evaluate the deterrence of oviposition activity against S. litura and H. armigera at 5, 10, 15, and 20毺 L/L concentrations. Results: The newly formulated different phytopesticides exhibited good results of oviposition deterrent activity against these two polyphagous insect pests. At 20毺 L/L concentration of PONNEEM, 77.48% of the maximum deterrence of oviposition activity was recorded, followed by formulation A (49.23%). And 68.12% was observed against H. armigera followed by A (49.52%). PONNEEM exhibited statistically significant oviposition deterrent activity compared to all other treatments. Conclusions: The newly formulated PONNEEM was found to be effective phytopesticidal formulation to control the adult of S. litura and H. armigera due to the synergistic effect of biomolecules such as azadirachtin and karanjin. This is the first report of PONNEEM which was patented under the government of India. The potential use of this novel phytopesticide could be an agent of controlling the adults of lepidopteran insect pests which can be applied in the integrated pest management programme. |
