摘　　要：本文研究了中黑盲蝽滞育卵经过4℃低温、35℃高温和全日照处理不同天数后的滞育解除情况。结果表明:4℃低温可以有效地解除中黑盲蝽卵的滞育,随着低温处理时间的延长,中黑盲蝽滞育卵的孵化率逐渐上升,处理60d后孵化率可达80.00%以上。全日照也能够有效地解除中黑盲蝽卵的滞育,滞育卵解除滞育后的孵化率也随处理天数增加而增加,处理40d,孵化率可达到40.00%以上。35℃高温不能解除中黑盲蝽卵的滞育。相对于非滞育卵,经4℃低温和全日照处理后,解除滞育的卵初孵时间有延迟现象,整个孵化历期延长。The diapause eggs of Adelphocoris suturalis （Jakovlev）were treated at 4 ℃,35 ℃ and continuous pho-tophase for different periods of days,respectively.The results indicated that 4 ℃ could terminate egg diapause ef-fectively.The hatching rate increased with the extension of treatment period at 4 ℃,reaching 80.00% 60 days after treatment.Continuous photophase could also terminate egg diapause effectively and the hatching rate also increased with the extension of treatment period.More than 40.00% of the treated eggs hatched when exposed to continuous photophase for 40 days.In contrast,the high temperature of 35 ℃ could not terminate egg diapause. Compared with non-diapause eggs,the time of first hatching was postponed for the eggs with diapause terminated at the lower temperature of 4 ℃ or continuous photophase,and the whole hatching duration was prolonged.
