Abstract

Termites are invasive and destructive invertebrate decomposers of dead organic matter in tropical and subtropical regions. Vitex negundo (Lagundi) is a large native shrub that can be found in Asia. Various studies have claimed that the plant possesses pesticidal, antifungal, and antibacterial properties. Hence, this study looked at possible variations in the effectiveness of Vitex negundo (Lagundi) ethanolic extract as a pesticide against termites. Testing involved concentrations of 50%, 75%, and 100%. Finding out if there were any appreciable differences in termite death rates between the various concentrations was the goal. For the experiment, termites were sprayed with various concentrations of Vitex negundo ethanolic extract. Following the application period, the quantity of deceased termites was counted. To determine whether there were any significant variations among the concentrations, statistical analysis using one-way ANOVA was conducted. The findings showed that the termite death rates among the concentrations varied significantly (p 0.05). Specific differences between different concentrations were identified by post-hoc analysis. The 75% concentration (mean: 98.00%) had the highest mortality rate, followed by the 100% concentration (mean: 94.95%), and the 50% concentration (mean: 90.60%). Contrary to the widespread belief that larger concentrations are generally more beneficial, the 75% concentration showed the maximum effectiveness. This unexpected outcome highlights how crucial it is to properly choose the concentration for the best possible pest control. Therefore, Vitex negundo ethanolic extract may be effective as a termite insecticide.
