摘要喜水莲子草细粉蚧Agasicles hygrophila Selman and沃格特（鞘翅目：粉蚧科）是喜旱莲子草Alternanthera philoxeroides（Mart.）灰芥（Amaranthaceae：Alternanthera）是一种世界性入侵杂草。大气CO2浓度升高可能对植物、食草昆虫和天敌产生重大影响。研究CO2浓度升高对中华绒螯蟹发育时间、繁殖力和种群参数的影响。利用年龄阶段两性生命表研究了单养和群养的喜湿草的适合度和种群参数。在CO2浓度升高的条件下，在单独饲养的种群中，成虫前期发育历期、成虫产卵前期历期和总产卵前期历期均较长。高CO_2（eCO_2，750 ppm）处理下的吸水性比低CO_2（aCO_2，420 ppm）处理下的短。在群聚饲养的种群中，成虫发育历期、雌成虫寿命、雌虫比例、成虫产卵前期和产卵前期总历期均显著高于群聚饲养的种群。eCO_2中的嗜水气单胞菌比aCO_2中的长。此外，在单独饲养和群聚饲养的种群中，产卵量和产卵日数均显著低于单独饲养和群聚饲养。在eCO 2中，嗜湿藻类的内禀增长率、有限增长率和净繁殖率均高于aCO 2;在eCO 2下观察到嗜湿植物。此外，在aCO 2和eCO 2下，群养组的成虫前期发育时间、成虫产卵前期、总产卵前期、雄成虫寿命和繁殖力均较低。结果表明，CO2浓度升高对A.群体饲养的种群增长速度快，后代数量多。
Abstract Agasicles hygrophila Selman and Vogt (Coleoptera: Chrysomelidae) is a natural enemy of Alternanthera philoxeroides (Mart.) Griseb (Amaranthaceae: Alternanthera), a worldwide invasive weed. Elevated atmospheric CO2 concentrations may have significant impacts plants, herbivorous insects, and natural enemies. To assess the concurrent effect of elevated CO2 on the development time, fecundity, and population parameters of A. hygrophila, the age-stage, two-sex life table was used to understand the fitness and population parameters of individually-reared and group-reared A. hygrophila under elevated CO2 concentration. In individually-reared population, the development time of preadults, adult pre-oviposition period, and total pre-oviposition period of A. hygrophila in the elevated CO2 (eCO2, 750 ppm) treatment were shorter than those in the ambient CO2 (aCO2, 420 ppm) treatment. In group-reared population, the developmental time of preadults, female adult longevity, female proportion, adult pre-oviposition period, and total pre-oviposition period of A. hygrophila in eCO2 were longer than those in aCO2. Additionally, in both individually-reared and group-reared population, fecundity and oviposition days of A. hygrophila in eCO2 were higher than those in aCO2, and a higher intrinsic rate of increase, finite rate of increase, and the net reproductive rate of A. hygrophila were observed at eCO2. Moreover, shorter preadult development time, adult pre-oviposition period, total pre-oviposition period, male adult longevity, and higher fecundity were found in group-reared cohort at both aCO2 and eCO2. The results indicates that elevated CO2 has effects on the growth and reproduction of A. hygrophila, and the population growth rate of group-reared was faster and produced more offspring.
