| 为明确不同光周期对井上蛀果斑螟Assara inouei Yamanaka生长发育及繁殖的影响, 在25℃, 70% RH, 光照强度5 500 lx及5种不同光周期(L∥D=8 h∥16 h?10 h∥14 h?12 h∥12 h?14 h∥10 h?16 h∥8 h)条件下, 研究了井上蛀果斑螟的生长发育和繁殖情况?结果表明, 光周期对井上蛀果斑螟幼虫和蛹的发育历期?幼虫存活率?化蛹率?羽化率?成虫寿命?产卵期?平均单雌产卵量有显著影响?在L∥D=16 h∥8 h光周期下幼虫期?蛹期和产卵期最短, 分别为18.8?8.2 d和7.8 d; 幼虫存活率?化蛹率?羽化率和平均单雌产卵量最高, 分别为67.4%?86.5%?93.3%和95.3粒?在L∥D=12 h∥12 h光周期下雌?雄成虫寿命和产卵期最长, 分别为15.8?15.1 d和12.5 d, 但幼虫存活率最低, 为38.9%?光周期对蛹重?成虫产卵前期和卵孵化率无显著影响?除L∥D=16 h∥8 h光周期外, 其余4种光周期下井上蛀果斑螟幼虫部分个体出现生长发育停滞现象, 滞育率在3.9%~6.9%之间?长光照有利于井上蛀果斑螟的生长发育及繁殖? |

| To clarify the effects of photoperiod on the development and fecundity of Assara inouei Yamanaka, the study had been conducted to observe the insect development, survival and reproduction at 25℃, 70% relative humidity, illumination intensity 5 500 lx under five photoperiods (L∥D=8 h∥16 h, 10 h∥14 h, 12 h∥12 h, 14 h∥10 h, 16 h∥8 h). The results indicated that the photoperiod had a significant effect on the developmental time, larval survival rate, pupation rate, emergence rate, longevity of adult, oviposition period and number of eggs laid per female. Under L∥D=16 h∥8 h photoperiod, the larval duration, pupal duration, and oviposition period were the shortest, which were 18.8, 8.2 d and 7.8 d, respectively, and the survival rate of larvae, pupation rate, emergence rate, and number of eggs laid per female were the highest, which were 67.4%, 86.5%, 93.3% and 95.3 eggs, respectively. Under L∥D=12 h∥12 h photoperiod, longevity of female and male adults and oviposition period were the longest, which were 15.8, 15.1 d and 12.5 d, respectively, but the survival rate of larvae was the lowest, which was 38.9%. The photoperiods had no significant effect on the pupa weight, pre-oviposition period and egg hatching rate of A. inouei. Except for the L∥D=16 h∥8 h photoperiod, some individuals of the larvae showed growth retardation under other four photoperiods, and the diapause rate ranged from 3.9% to 6.9%. Longer photoperiods are favorable for the development and fecundity of A. inouei. |
