中文摘要:
      云南派姬小蜂Pediobius yunnanensis Liao 是寄生于微红梢斑螟Dioryctria rubella Hampson蛹的内寄生蜂,目前国内外对其有效积温和发育起点温度尚无报道。本文以微红梢斑螟蛹为繁殖寄主,在15、20、25、30℃和35℃共5个恒温条件下,研究了云南派姬小蜂各虫态的发育历期、发育起点温度和有效积温。结果表明,在20~30℃温度范围内, 云南派姬小蜂的各阶段及世代的发育历期随着温度的升高而缩短; 卵-幼虫、蛹、成虫、全世代的发育起点温度分别为(15.83±0.18)、(13.63±1.11)、(14.27±1.36)℃和(15.43±0.48)℃。有效积温分别为(128.66±3.33)、(132.34±17.25)、(57.92±7.25)日·度和(291.37±10.73)日·度。
英文摘要:
      Pediobius yunnanensis Liao (Hymenoptera: Chalcidoidea: Eulophidae) is an endoparasitic wasp parasitic to the pupa of Dioryctria rubella Hampson, and its biological characteristics have not been reported. The developmental duration, developmental threshold temperature and effective accumulated temperature of the P.yunnanensis were investigated under the constant temperature conditions of 15, 20, 25, 30℃ and 35℃. The results showed that the developmental duration of different stages and whole generation of P.yunnanensis become shorter with increasing temperature from 20℃ to 30℃. The developmental threshold temperatures of egg-larva, pupa, adult, host intra pupa generation and whole generation were (15.83±0.18), (13.63±1.11), (14.27±1.36) and (15.43±0.48)℃, respectively. The effective accumulated temperatures were (128.66±3.33), (132.34±17.25), (57.92±7.25) and (291.37±10.73) degree-days, respectively.
