摘　　要：昆虫滞育反应的种内差异包括品系差异和个体差异。品系差异是昆虫适应不同环境条件的结果,主要随纬度的变化而变化。通常随着纬度的升高,冬季滞育的滞育率也升高,诱导其滞育的临界光周期也随之延长。个体差异表现在进入滞育趋势、滞育强度和滞育后发育的性别差异。Intraspecific differences of diapause include strain differerces and individual differences.Strain differences always are caused by adaptation to different local conditions;it mainly depends on varying latitude.In general,as latitude increases,the incidence of winter and the critical photoperiod increase.Individual differences may be sexual differences in the occurrence of diapause,diapause intensity and the rate of post-diapause development.
