赤色LED光照射および光反射シート被覆が施設ナスのネギアザミウマの発生に及ぼす影響

抄録

The effects of red LED light irradiation and reflective sheet cover on the population density of the onion thrips, Thrips tabaci Lindeman, were investigated on eggplants in a greenhouse in 2016. Four experimental plots were set up by combining the illumination of red LED lights and the cover of the reflective sheet. The eggplants were cultivated from May to June. As a result of the experiment, the population densities of larvae tended to be in order of low to high in the following plots: the plot with both the red LED lights and reflective sheet, the plot with the red LED lights and no reflective sheet, the plot with the reflective sheet and no red LED lights, and the plot without the red LED lights or the reflective sheet.
