ネギハモグリバエ（ハエ目：ハモグリバエ科）の発育に及ぼす温度・日長の影響と増殖能力

抄録

The effects of temperature and photoperiod on the development（oviposition to adult emergence）of Liriomyza chinensis Kato at five constant temperatures（15, 18, 20, 25, and 30°C）under a 15L9D photoperiod and at 18°C under a 10L14D photoperiod, and its reproductive potentials and adult longevity at three constant temperatures（20, 25, and 30°C）under a 15L9D photoperiod were examined on Welsh onion plants. The total developmental period of L. chinensis decreased from 68.3 days at 15°C to 19.4 days at 30°C with a 15L9D photoperiod. A significantly longer developmental period was found with a 10L14D than 15L9D photoperiod at 18°C. The developmental zeros for the total development was 9.1°C. The effective accumulative temperature was 393.6 day-degrees. The adult emergence rates were the highest at 20°C. The next generation adults were highest at 25°C（103.6/female）. Female adult longevities at 20, 25, and 30°C were 17.8, 12.9, and 6.5 days, respectively. The intrinsic rates of natural increase at 20, 25, and 30°C were 0.06, 0.10, and 0.09, respectively.
