Sex and strain-specific spectral attraction of Tribolium castaneum (Coleoptera: Tenebrionidae): behavioral studies

Abstract We examined the attraction of adults to six LEDs in red flour beetles, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), which is widespread as a stored grain insect. In experiment, bluish green and were more attractive than two UVs, blue, only females. On other hand, no difference was found among males. Next, we investigated relationship between light intensity attractiveness. No sexual attractiveness different intensities found, but strongest intensities. Finally, strains artificially selected for duration death feigning. Short-strain beetles attracted UV lights long-strain beetles.
