摘要
为探明光周期对绿盲蝽种群增殖的影响,应用种群生命表的方法(温度(25±1)℃、相对湿度(70±5)%、光照强度4000 lx),系统研究了绿盲蝽(Apolygus lucorum Meyer-Dür)在5个光周期L︰D=8︰16,10∶14,12︰12,14︰10和16︰8下的实验种群的生长发育特性和繁殖能力。结果表明,不同光周期处理下绿盲蝽各虫态存活率、产卵前期及产卵量等均有显著性差异。不同光周期处理下,绿盲蝽最高孵化率(L︰D=10︰14)比最低孵化率(L︰D=16︰8)高25.06个百分点;若虫最高存活率(L︰D=8︰16)比最低存活率(L︰D=16︰8)高25.26个百分点;雌成虫最高平均产卵量(L︰D=12︰12)比最低平均产卵量(L︰D=8︰16)多27.29粒。综合来看,光周期L︰D=12︰12处理下的绿盲蝽种群内禀增长率(rm)最大(0.1093),种群加倍时间(DT)最短(6.3417),表明该光周期处理十分有利于绿盲蝽种群的发育与繁殖。
The effects of different photoperiods（L︰D=8︰16,10︰14,12︰12,14︰10,16︰8） on the characteristic of development and fecundity of Apolygus lucorum Meyer-Dür were studied using life table methods.Apolygus lucorum Meyer-Dür was reared in climate incubator with temperature（25±1）℃,relative humidity（70±5）℃ and illumination intensity 4000 lx.The survival rates of each stadium,preoviposition duration and fecundity of female adults were significantly different among the five photoperiods.The maximum hatching rate（L︰D=10︰14） was 25.06% higher than the minimum（L︰D=16︰8）;the highest nymph survival rate（L︰D=8︰16）was 25.26% higher than the lowest（L︰D=16︰8）;the maximum average fecundity（L︰D=12︰12）of female adults was 27.29 more than the minimum（L︰D=8︰16）.In the photoperiod L︰D=12︰12,the intrinsic rates of natural increase（rm） was the largest（0.1093）while the double time（DT） was the shortest（6.3417）,which indicated that the photoperiod L︰D=12︰12 was very beneficial to development and fecundity of Apolygus lucorum.
