研究了低温驯化对阿里山潜蝇茧蜂Fopius arisanus(Sonan)的影响,结果显示,阿里山潜蝇茧蜂雌雄成蜂SCP、FP均随驯化时间的延长呈先升高后下降的趋势,当处理时间为24 h时,雌雄成蜂SCP、FP均达到最高值,(SCP分别为雌-7.66±0.27℃、雄-7.22±0.31℃,FP分别为雌-2.95±0.16℃、雄-2.58±0.23℃)与对照差异显著;处理时间为72 h时,雌雄成蜂SCP、FP均达到最低值(SCP分别为雌-9.76±0.30℃、雄-8.98±0.28℃,FP分别为雌-5.08±0.23℃、雄-4.28±0.28℃),但与对照无显著性差异;相同处理时间,雄虫SCP值高于雌虫。从头年的12月份到次年的3月份,随着时间的推移,阿里山潜蝇茧蜂越冬雌雄蜂的SCP、FP均低于室内饲养的对照组,到次年3月份雌雄虫SCP、FP均降至最低值(SCP分别为雌-12.24±0.23℃、雄-11.37±0.26℃,FP分别为雌-6.65±0.24℃、雄-5.81±0.24℃),且同月份雌蜂的SCP、FP均低于雄蜂。阿里山潜蝇茧蜂越冬代成蜂寄生率及其子代的羽化率均随时间的推移先下降后上升,但均低于对照组;寄生率及其子代的羽化率均在次年2月份时降至最低(寄生率为37.12±1.04,羽化率为9.68±0.47),且与对照组相比差异显著。
The effects of cold acclimation on Fopius arisanus (Sonan) in Alishan were investigated. The results showed that the SCPs and FPs of the male and female adults of Aleuron were both increased first and then decreased with the extension of acclimation time. The SCPs of both male and female reached the highest values at 24 h (SCP = -7.62 ± 0.27 ℃, -7.22 ± 0.31 ℃, FP = -2.95 ± 0.16 ℃, and -2.58 ± 0.23 ℃) was significantly different from that of the control (P <0.05). When the treatment time was 72 h, the SCPs and FPs of the male and female adults reached the lowest values (SCP = -9.76 ± 0.30 ℃ and -8.88 ± 0.28 ℃, FP = -5.08 ± 0.23 ℃, male -4.28 ± 0.28 ℃), but no significant difference with the control; the same treatment time, the male SCP value higher than the female. From December of the first year to March of the following year, the SCPs and FPs of overwintering female and male bees of Alishan moths were lower than those of the control group, while the female and male SCPs and FPs (SCP = -12.24 ± 0.23 ℃, male -11.37 ± 0.26 ℃, FP = -6.65 ± 0.24 ℃, male -5.81 ± 0.24 ℃, respectively), and in the same month female SCPs, FP Are lower than the drone. The parasitism rate and the emergence rate of their offspring of Alishan mongolian were firstly decreased and then increased, but both were lower than that of the control group. The parasitism rate and the emergence rate of their offspring were both in the following year 2 The lowest in the month (parasitic rate was 37.12 ± 1.04, the emergence rate was 9.68 ± 0.47), and the difference was significant compared with the control group.
