The effects of red-light irradiation and a reflective sheet cover on the population density of two thrips species (Thysanoptera: Thripidae), the melon thrips (Thrips palmi Karny) and the onion thrips (Thrips tabaci Lindeman), were investigated on eggplant and cucumber in a greenhouse in 2014 and 2015. Red fluorescent lamps were illuminated from above the plants and a light reflecting sheet was placed on the ridges of the treated plots. A greenhouse without either material was set up as a control plot. The population densities of the two thrips species on eggplant and T palmi on cucumber were significantly lower in the treated plots than in the control plot.
