[Display omitted] •The LED light at UV or near-UV can enhance the establishment of natural enemies.•Inter-strain variation in attraction to wavelengths was observed in O. laevigatus.•The 385 nm wavelength was the most attractive light wavelength to O. laevigatus. Inter-strain variation in attraction to specific LED wavelengths has been studied previously. Here, we report on differences in attraction of two commercialized strains (Biobest and Koppert) of Orius laevigatus to 10 or 11 different LED wavelengths. We found a significant difference in attraction patterns among the tested wavelengths between the two insect strains; for the Biobest strain, attraction was the highest in 365 and 385 nm wavelengths, while for the Koppert strain, it was the highest in 365, 385, 395, and 405 nm wavelength. As both strains showed highest attraction rate at a wavelength of 385 nm, lights with this output could be used in field pest management strategies.
