Abstract: The thrips species, Thrips tabaci Lindeman and Frankliniella occidentalis (Pengande) (Thysanoptera: Thripidae), are the most common pests on agricultural crops in Colorado. The yellow cup baited with crushed freeze-dried canola pod extract caught significantly higher numbers of thrips species than baited with ground mustard seed in the first trial. The blue cup baited with mustard oil caught the highest number of thrips species at second trial. In addition, blue cup baited with canola and mustard oil caught three and four times much higher numbers of thrips species than yellow cup baited with raw canola and mustard oil in third trial. This study also appears to be the first showing that secondary host plant compound can increase captures of thrips species at the organic farm.
