中文摘要：

【目的】使昆虫两性生命表研究能省时省力地记录产卵量,同时维持分析的准确性。【方法】本研究以每日记录产卵量的烟粉虱Bemisia tabaci MED隐种（通常称为Q型）感染与未感染Cardinium的2个品系的原始数据为基础,将产卵量按照每2,4和5 d进行简化记录,以验证这种方法的有效性及其对种群参数的影响,并进行显著性分析。【结果】除成虫产卵前期（adult preoviposition period,APOP）和产卵天数受到影响外,简化记录方法对内禀增长率（intrinsic rate of increase,r）、周限增长率（finite rate of increase,λ）、净增殖率（net reproductive rate,R0）、平均世代周期（mean generation time,T）、成虫前历期、繁殖力、雌雄虫寿命和总产卵前期（total preoviposition period,TPOP）均无显著性影响。【结论】结果说明,这种简化记录方法对生命表的主要参数无显著性影响,可用于生命表研究中以节省时间与劳力,并且减小每天检视可能对成虫造成的影响,有利于两性生命表的广泛应用。

英文摘要：

【Aim】In order to save time and labor in life table studies and still to maintain the accuracy of the analyses involved,we tested the effects of changing the frequency of data sampling for two strains（ infected and uninfected by Cardinium） of Bemisia tabaci MED cryptic species（ commonly known as biotype Q） on their population parameters. 【Methods 】 Based on the raw data recorded daily,the simplified data of the sampling intervals of 2,4 and 5 d were re-analyzed to test the significant differences between the treatments. 【Results 】 No significant differences between the treatments existed in the population parameters including the intrinsic rate of increase（ r）,finite rate of increase（ λ）,net reproductive rate（ R0）,mean generation time（ T）,preadult duration,fecundity,female longevity,male longevity,and total preoviposition period（ TPOP） obtained through daily sampling and the interval-grouped data,except the adult preoviposition period（ APOP） and ovip osition days. 【Conclusion】Our results demonstrated that the simplified recording method has no significant effects on the evaluation of the key population parameters and can be used in life table studies with less time and labor. In addition,the simplified recording method may decrease the interference to observed adults due to reduced daily observation. Consequently,the simplified method may be helpful to promote the application of the age-stage,two-sex life table.
