Evaluation of biopesticide against Sitophilus Oryzue L.

On a worldwide scale, rice is the third most produced agricultural product, therefore insect pest losses in t ice storage might have a considerable influence on food supply for a huge number of people. The Sitophilus oryzae L., is one of the most problematic pests in the tropics. Despite the fact that there are few effective fumigants, environmental contamination, non-target organism toxicity, and pesticide residues are all major concerns. Botanicals are a prospective source of pest control chemicals since there are so many plants that contain insecticidal compounds, and they've sparked a lot of attention in recent years as possible natural pesticide sources. The primary goal of this research was to determine the toxicity and repellency of Aloin and citronella oil on S. oryzae L This study was designed using three distinct Aloin extract treatments (5 percent, 10%. and 15%) and two control treatments using ANOVA test. The results revealed that at 15% concentration, the most toxic and repellent effects were observed, followed by 10% and 5%, while insect mortality percentage was found to be directly proportional to time after treatment, and the repellent effect increased proportionally to the level of Aloin extract concentration. Furthermore, the results revealed that 15% concentration had the maximum toxicity and repellency against rice weevil, followed by 10%, and the lowest was found in control (0%) followed by 5% concentration. At the conclusion of the study, we demonstrated that the biopesticide is effective against S. oryzae in terms of mortality and repellency. Our agriculture sectors would benefit from research into improving the effectiveness of botanical derivatives as alternatives to synthetic insecticides because these botanicals are not only less expensive but also have a lower environmental impact than insecticides.
