南瓜实蝇的发育起点温度和有效积温

摘要

The threshold temperature and effective accumulated temperature of each stage of Bactrocera tau (Walker)were investigated under five constant temperatures of 18,22,26,30 and 34 ℃.The results showed that threshold temperatures of egg,larva,pupae,preoviposition and whole generation(egg-egg)were 13.10 ±2.35, 9.86±1.47,12.87±1.36,9.66±0.91 and 9.54±0.89 ℃,respectively.The effective accumulated temperatures of each stage were 26.30±4.57,134.04 ± 1 1.38,149.92 ± 36.92,1 57.56 ±43.64 and 542.25 ±24.79 day-de-grees,respectively.%在18、22、26、30和34℃5种恒温条件下,测定了南瓜实蝇[Bactraera tau (Walker)]各虫态发育起点温度及有效积温。结果表明,南瓜实蝇卵、幼虫、蛹、产卵前期和全世代的发育起点温度分别为(13.10±2.35)、(9.86±1.47)、(12.87±1.36)、(9.66±0.91)和(9.54±0.89)℃,有效积温分别为(26.30±4.57)、(134.04±11.38)、(149.92±36.92)、(157.56±43.64)和(542.25±24.79)日·度。
