- Abstract
The house rat (Rattus rattus) is the most destructive commensal rodent pest. The use of rodenticides is the most commonly used method for the control of rodents. However, the drawbacks of using rodenticides such as nontarget toxicity, environmental hazards, and development of resistance have increased the search for plant products acting as repellents or antifeedants against rodent pests. Capsaicin is the active ingredient of red chilli responsible for causing irritating and pungent effects. The present study was conducted to evaluate the aversive effect of pure capsaicin against both sexes of house rat, R. rattus. Different groups of rats were fed on baits containing 0.01 and 0.03% pure capsaicin for a total of 14 days with a gap period of 7 days in bi-choice feeding tests. Rats of the control group were fed on plain bait. Results showed that mean daily consumption of treated bait was significantly (P ≤ 0.05) low from that of untreated baits indicating the aversive effect of the capsaicin. There was a significant difference in the antifeedant index (P ≤ 0.05) between 0.01% and 0.03% concentration showing higher aversion at 0.03% of pure capsaicin.
