Abstract
The use of plant-derived oils and extracts and their active constituents as safe alternatives for pest control has been emphasized as an important tool to be incorporated in integrated pest management (IPM) programs that can help to fulfill the efficacy and safety of pest control products. The objective of this work was to determine the ovicidal activity of petroleum ether extract of black pepper fruits and piperine isolated from acetone extract on the egg hatchability of the European corn borer, Ostrinia nubilalis (Hubner) in the laboratory. The potential phytotoxic effect of black pepper extracts on the seed germination of the little seed canary grass (Phalaris minor), sorghum (Sorghum bicolor) and cucumber (Cucumis sativus) was also studied. The ovicidal activity of the tested applied concentrations of black pepper oil extract and piperine was increased with the increase in concentrations, and egg mortality (non-hatch) percentage ranged between 20.4 to 100%. Pepper oil extract and piperine showed significant inhibitory activity on seed germination of canary grass at all concentrations tested with good selectivity with sorghum and cucumber at the applied lower concentrations of 500 and 1000 µg/ml. Results suggest that black pepper oil extract and piperine are promising alternative biopesticidal agents for the control of O. nubilalis egg masses and reducing the germination of the harmful canary grass in field crops and could be included as a viable component of the IPM system.
