摘　　要：本文研究了浸水处理和土壤相对含水量对番石榴果实蝇(Bactrocera correcta(Bezzi))羽化率的影响。结果表明:不同的浸水时间对不同蛹龄番石榴果实蝇蛹羽化率的影响不同。蛹龄越大,浸水作用对其影响越低;浸水时间越长,番石榴果实蝇蛹羽化率越低。浸水时间(T)、蛹期(A)和蛹羽化率(ER)之间关系符合以下模型:ER=0.675-0.00393T+0.1177A-0.00001997T^2-0.01194A^2+0.0007292T×A。土壤含水量对番石榴果实蝇羽化率影响明显。土壤含水量低于30%或高于90%时,番石榴果实蝇羽化率都明显受到抑制。相对含水量(M)和成虫羽化率(ER)之间存在以下关系:ER=0.422+1.547 M-1.322M^2。The influence of water immersion and soil relative moisture on Bactrocera correcta pupae emergence rate was researched in this study. The result indicated that when the pupae were immersed in the water, the emergence rate was affected significantly by the time and the pupae age. With the time getting longer, the pupae emergence rates get lower. The water immersion had little influence on the old stage pupae. The relationship among the time of water immersion （ T）, pupae age （A） and pupae emergence rate （ER） can be modeled as ： ER = 0.675 - 0.00393 T ＋ 0.1177A- 0. 00001997 T^2 - 0.01194A^2 ＋ 0. 0007292T x A. Soil moisture less than 30% or more than 90% could affect the emergence rate of the adults. The relationship between the emergence rate of adult （ER） and soil moisture content （M） was described as ER =0.422 ＋ 1. 547 M - 1. 322M^2.
