摘要
在室内自然变温条件下研究了番石榴实蝇Bactrocera correcta(Bezzi)发育历期、发育起点温度和有效积温。结果表明,除雌虫产卵前期表现出26℃最短、随着温度升高或者降低均延长的规律外,卵、幼虫和蛹发育历期随着温度升高总体呈现变短的趋势。该虫卵、幼虫、蛹、雌虫产卵前期的发育起点温度和有效积温分别为15.25、9.24、10.35、20.14℃和21.24、91.06、180.85、135.66日·度,建立了各虫态发育速率与温度关系模型。
The durations of the egg,larval,pupal,and pre-oviposition stages of Bactrocera correcta（Bezzi） were recorded under natural conditions,and developmental threshold temperatures and effective cumulative temperatures determined.Except for pre-oviposition which had the shortest duration at 26℃,the durations of the egg,larval and pupal stages all decreased with increasing temperature.Developmental threshold temperatures for eggs,larvae,pupae,and pre-oviposition were 15.25,9.24,10.35 and 20.14℃,and effective accumulative temperatures were 21.24,91.06,180.85 and 135.66 degrees-days,respectively.A model of the relationship between temperature and developmental rates for these four life-history stages was developed.
