Tableted corn bait of 4-Aminopyridine was laboratory evaluated against Psittacula krameri at three concentrations (2%, 2.5% and 3.0%) and three different dose levels within each concentration (23.85,71.87 and 122.44 mg/bird). The data analysis showed significant difference (P < 0.05) among the three concentrations in respect of the duration of vocal distress calls. The change in concentration and dose had nonsignificant effects (P < 0.05) on the time from dosing to first call. Similarly, change in dose also had a non-significant effect (P > 0.05) on the duration of vocal calls. Numbers of calls were significantly affected with the increase in concentration of 4-AP, but within three dose levels this effect was in the reverse order. Field trials are required to test the efficacy of 4-AP at these three bait concentrations against this psittid.
