Interpretive Summary: We studied light response of western flower thrips in a darkroom. Results showed that they were attracted to blacklight compared with blue, green, yellow, red and white colors. Test of distance between light source and thrips release point indicates that thrips response to lights are in short distances.

Technical Abstract: Spectral responses of adult western flower thrips (WFT) Frankliniella occidentalis (Pergande) were determined using a parti-colored light array (PLA) system under darkroom conditions. The PLA system consisted of thirty different light source boxes arranged in six boxes (in two columns of three each) per replicate of five replicates. The highest number of released WFT adults were attracted to ultraviolet (UV) (peak wavelength 369 nm) compared with blue (460 nm), green (512 nm), yellow (545 nm), red (650 nm), and non-colored white light. Distances from the point of WFT release to the PLA affected the number of WFT caught independent of color.
