中文摘要:为明确温度、光周期对日本食蚧蚜小蜂Coccophagus japonicus Compere发育与繁殖的影响,在不同温度、光周期条件下观察日本食蚧蚜小蜂的发育历期、出蜂数、雌蜂寿命以及寄生率。结果表明:温度和光周期显著影响日本食蚧蚜小蜂种群增长。在18~30℃之间,日本食蚧蚜小蜂的发育历期及雌蜂寿命均随温度的升高而缩短,18℃时发育历期与雌蜂寿命最长,分别为60.9 d和29.9 d,30℃时发育历期最短,为21.3 d,33℃时雌蜂寿命最短,为8.3 d;18~24℃之间,寄生率及出蜂数随温度的升高而增加,24℃时最高,分别为77.1%和38.7头;24~30℃之间,随温度升高日本食蚜小蜂的寄生率及出蜂数呈下降趋势。在光周期L 8 h∶D 16 h~L 16 h∶D 8 h范围内,当光周期为L 12 h∶D 12 h时,日本食蚧蚜小蜂的发育历期最短,为22.1 d,出蜂数最高,为39.0头;当光周期为L 14 h∶D 10 h时,雌蜂寿命最长,为22.6 d,寄生率最高,为71.1%。表明温度24~27℃、光周期L 12 h∶D 12 h为日本食蚧蚜小蜂种群增长的最适温度和光周期条件。

Abstract:In order to clarify the effects of temperature and photoperiod on the development and reproduction of endoparasitoid wasp Coccophagus japonicus Compere, the developmental duration, production of wasps, female lifespan and parasitism rate of C. japonicus were observed under different temperatures and photoperiod conditions. The results showed that temperature and photoperiod significantly affected the population growth of C. japonicus. In the range of 18-30℃, the developmental duration and female lifespan were shortened with increasing temperature. At 18℃, the developmental duration and female lifespan were the longest (60.9 d and 29.9 d, respectively). The developmental duration was the shortest at 30℃ (21.3 d), and the female wasps had the shortest lifespan at 33℃ (8.3 d); in the range of 18-24℃, the parasitism rate and the number of wasps increased with increasing temperature, and the highest values were recorded at 24℃, which were 77.1% and 38.7, respectively; in the range of 24-30℃, with the increase of temperature, the parasitism rate and the number of wasps showed a downward trend. In the range of L 8 h:D 16 h to L 16 h:D 8 h photoperiods, when the photoperiod was L 12 h:D 12 h, the developmental duration of wasps was the shortest (22.1 d) and the number of wasps was the highest (39.0); when the photoperiod was L 14 h:D 10 h, the female had the longest lifespan (22.6 d), and the parasitism rate was the highest (71.1%). It suggested that the optimal temperature and photoperiod conditions for the growth of C. japonicus populations were 24-27℃ and L 12 h:D 12 h.
