Abstract: Scopula subpunctaria (Herrich-Schaeffer) is one of the most common pests of tea plant. In order to feed this pest successfully in laboratory, the effects of different nutrition supplementations on the longevity and fecundity of Scopula subpunctaria were investigated in this study. The results show that, when the adult females were supplemented with 10% honey water and 10% sugar water, the mean fecundity per female was significantly increased, which was 152.5±16.83 and 177.5±19.01, respectively. While the oviposition period of adult females was significantly extended, which was (17.8±1.08) d and (21.4±1.27) d, respectively. Supplementation of different nutrients had significant effects on oviposition and post-oviposition periods, but not significant on pre-oviposition period. When 10% sugar water was supplied, the longevity of female adult was the longest (29.1±1.41 d), which was significantly higher than those of other treatments. In 10% honey water, water and control treatments, the longevities of adult females were (23.8±1.15) d, (14.4±0.48) d and (6.3±0.37) d, respectively. When supplemented with 10% sugar water and 10% honey water, the longevities of adult males were (21.3±0.93) d and (19.5±1.20) d, respectively, which were significantly higher than those of water and control treatments. In each treatment, the longevity of female adult was longer than that of the male. The results show that 10% sugar water could be used as the best nutrient supplement for adult, successful indoor rearing of Scopula subpunctaria would provide important guarantee for other related researches.
