Abstract:

Objective In order to understand in vitro development rules of Gasterophilus pecorum and lay the foundation for further study of this myiasis. Methods Collected the mature larvae of G. pecorum from Przewalaski's Horse in April 2014, cultured pupae under the natural varying temperature. Record the average temperature of development and developmental duration, the developmental threshold temperature and effective accumulated temperature for pupae of G. pecorum were determined by using rule of effective temperature summation“least square method”. Results (1) The developmental threshold temperature had a range of (10.58± 0.64)℃ and the effective accumulated temperature had a range of (190.95 ± 24.85) d·℃; (2) Unary linear regression equation was established between the developmental temperature and developmental rate: (V=-0.0541 + 0.0052T). The linear regression analysis showed a significant relationship between the developmental temperature and developmental rate (r2=0.923, P=0.001); (3) The development duration prediction for pupae of G. pecorum was established: N=(190.95± 24.85)/[T-(10.58± 0.64)]. Conclusion Through the investigation of local temperature, the development duration prediction for pupae of G. pecorum was applied to predict the adult emergence period of G. pecorum. Combined with the larvae investigation of G. pecorum can provides effective scientific basis for predict adult occurrence dynamics of G. pecorum.

摘要:

目的 探究黑腹胃蝇在宿主体外发育规律,为马胃蝇后续研究奠定基础。方法 2014年4月通过在野外跟踪野马收集自然排出的黑腹胃蝇老熟幼虫,以成功化蛹的黑腹胃蝇蛹为研究对象,在自然变温条件下对其进行培养,记录期间的发育平均温度和发育历期,运用有效积温法则中“最小二乘法”对其发育起点温度和有效积温进行计算。结果 ①黑腹胃蝇蛹的发育起点温度为(10.58±0.64)℃,有效积温为(190.95±24.85)d·℃;②蛹期发育速率与发育温度间的关系符合一元线性回归方程(V=-0.0541+0.0052T),发育温度与发育速率之间的线性关系显著(r2=0.923,P=0.001);③黑腹胃蝇蛹发育历期预测式N=(190.95±24.85)/〔T-(10.58±0.64)〕。结论 通过对当地温度的调查,运用黑腹胃蝇蛹发育历期预测式能够预测黑腹胃蝇成虫在当地的发生期,结合当年幼虫基数的调查,进而为预测成虫发生动态提供有效的科学依据。
