The predatory mites, widely used as natural enemy control source, was reared for 3 weeks in various environments of four temperature ranges (15℃, 20℃, 25℃, 30℃), 70 RH, and 1000 lux of illumination to identify the optimal rearing temperature by checking the number of individuals. A 1000 × 1000 × 700 mm acrylic outer breeding boxes were made to control the breeding environment and device that controlling temperature and humidity were installed inside. Referring to the double box breeding method of Jung DW et al. (2018), The inner breeding box was placed in outer acrylic box. As a result of breeding, it was found that the number of individuals increased by 11.3 times at 25℃, making it the most suitable for breeding.
