? 2022The wavelength of light can affect reproduction and development of arthropods. In the present study, we examined the reproduction and development of predatory thrips Scolothrips longicornis Priesner (Thysanoptera: Thripidae) fed on Tetranychus urticae Koch (Trombidiformes: Tetranychidae) eggs, under five wavelengths: white (all wavelengths), blue (475 nm), green (580 nm), yellow (620 nm) and red (675 nm), at 25 ± 0.5 °C, 16L: 8D and 60 ± 10% rh. Light wavelength did not significantly influence female and male preadult duration, male adult duration, and male total longevity. White and blue light yielded the longest oviposition periods. All life table parameters varied significantly among treatments. The intrinsic rate of increase (rm d?1) was lowest in red light wavelength (0.112 ± 0.009) and highest in white wavelength (0.171 ± 0.008) and blue light wavelength (0.168 ± 0.008). The present research demonstrates that white light conditions positively influence S. longicornis with shorter development time and improved reproductive performance. This information will be beneficial in mass production of S. longicornis for biocontrol programs involving T. urticae.
