Adult of Spodoptera exigua populations were monitored in Cameron Highlands using pheromone traps between 24 January 2003 and 27 February 2004 in the vegetables farm and between 24 March 2003 and 27 February 2004 in the carnation farm at Kampong Raja. They were captured all the time in the studied areas, although the numbers fluctuated. The highest number of adult catches per trap per day was 5.75 individuals between 6 to 13 June 2003, followed by 5.14 individuals between 23 to 30 May 2003 at the vegetables farm. The lowest number of adult catches per trap per day was 0.25 individuals between 3 to 10 October 2003. Whereas, at the carnation farm, the highest number of adult catches per trap per day was 1.22 individuals between 25 July to 8 August 2003. The lowest number of adult catches per trap per day was 0.06 individuals between 31 October to 7 November 2003 and 30 January to 6 February 2004. In general, capture increased towards the middle part of the year with four capture peaks occurring between April and June 2003 at the vegetables farm. Whilst, at the carnation farm, there were several capture peaks occured between April and October 2003. Thus, this date could be used as a benchmark to determine when and if population levels are high enough to have the potential to cause economic damage to crops in Cameron Highlands, Pahang. © 2008 Academic Journals Inc.
