摘　　要：目的了解室内饲养德国小蠊卵鞘在不同温度下孵化变化情况,为其室内饲养和室外监测提供参考数据。方法将德国小蠊雌虫单只饲养,1只/管,60管/组,分成4组,置于(24.00±1.00)℃+(60.00±5.00)%、(27.00±1.00)℃+(60.00±5.00)%、(27.00±1.00)℃+(70.00±5.00)%、(30.00±1.00)℃+(70.00±5.00)%条件下,每天观察记录卵鞘携带时间、产卵鞘间隔时间以及孵化若虫数。结果德国小蠊卵鞘孵化若虫数最多为(35.46±2.98)只;多次产卵鞘的孵化若虫数差异无统计学意义(χ^(2)=1.910,P=0.385);卵鞘携带时间随温度升高而缩短;若虫数与卵鞘长度有显著相关性(r=0.572,P=0.000),与温度、湿度无显著相关性(r=-0.221,P=0.053;r=0.079,P=0.542);孵化若虫数与孵化卵鞘携带时间、孵化卵鞘时间间隔无显著性相关(r=-0.097,P=0.577;r=-0.184,P=0.357)。结论温度、湿度对德国小蠊卵鞘孵化若虫数无显著影响,温度主要影响卵鞘孵化活力及携带时间。Objective To study the hatching ability of B.germanica ootheca at different temperatures,providing reference for breeding indoors and surveillance outdoors.Methods Every female B.germanica was reared in a breeding tube,1 group included 60 tubes.4 groups were placed at(24.00±1.00)℃+(60.00±5.00)%,(27.00±1.00)℃+(60.00±5.00)%,(27.00±1.00)℃+(70.00±5.00)%,(30.00±1.00)℃+(70.00±5.00)%to observe the carrying time and nymphs of B.germanica ootheca and the interval between oothecae.Observed the ootheca every day and counted nymphs.SPSS 26.0 software was applied to perform analysis of nymphs,carrying time of ootheca,intervals.Results The maximum nymphs was(35.46±2.98).There was no significant difference among the amounts of nymphs in multiple spawning oothecae(χ^(2)=1.910,P=0.385).The carrying time of ootheca decreased with increasing temperatures.The amounts of nymphs was significantly correlated with the length of ootheca(r=0.572,P=0.000),but had no significant correlation with temperature and humidity(r=-0.221,P=0.053;r=0.079,P=0.542).The amounts of nymphs had no significant correlation with carrying time of ootheca and spawning oothecae intervals(r=-0.097,P=0.577;r=-0.184,P=0.357).Conclusion Temperature and humidity had no obvious effect on amounts of nymphs of B.germanica ootheca,temperature mainly affecting the ootheca hatching ability and carrying time.
