Results revealed that 5% cinnamic aldehyde and 0.4% cinnamamide treated bait have antifeedant/secondary repellent effect against house rat R. rattus which retained both at a gap of 7 (treatment period 2) and 14 (treatment period 3) days of treatment. Rats were not habituated to effective concentration of cinnamic aldehyde upto experimental period of 27 days. There was no significant difference between consumption of treated and untreated bait during first four hours after exposure of rats to effective dose of both the compounds under both no-choice and bi-choice feeding tests indicating absence of primary repellent effect of both compounds. Formulations of both compounds containing NaHCO3 prevented the rodent damage in terms of consumption of wheat grains (g/100 gm body weight), number of cuts, size of cuts (cm), quantity of spilled grains (g) and contamination of wheat grains due to rat urine upto experimental period of 15 days. Study of rat behavior in I-maze under Ethovision Video Tracking System confirmed the absence of primary repellent effect and study of feeding behavior in Feed Scale Consumption Monitor (FSCM) confirmed the existence of secondary repellent/ antifeedant effect of cinnamic aldehyde and cinnamamide against house rat R. rattus.
