Abstract: We measured the phototactic behavior of the western flower thrips, Frankliniella occidentalis (Pergande) under the LED light of various spectral content and intensity. The light intensity required to elicit a 50% behavioral response to the stimulus yielded the action spectrum of the phototactic behavior. The action spectrum peaks at 525 and 355 nm, between 355 to 660 nm. This profile reasonably fits the spectral sensitivity of the compound eye as determined by the electroretinographic method. In a choice experiment where the insects were subjected to select either 355 nm or 525 nm of equal photon flux, they preferred 355 nm to 525 nm, indicating that the insects prefer ultraviolet (UV) radiation under the condition of multiple light sources.
