- 摘要：
- In this study, we compared the growth,development, and fecundity of Arma chinensis (Fallou) reared on pupae of the geometrid Ectropis grisescens Warren fed on tea shoots during different seasons ofthe year. The raw data on life history were analyzed using the age–stage, 2-sexlife table. When reared on spring or winter geometrid pupae, the duration ofthe immature stage of A. chinensis was significantly longer than in thoseproduced during the summer or autumn. The survival rate of immature A. chinensis reared on autumn geometrid pupae was significantlylower compared to other treatments. Reproductive diapause was observed in adult A. chinensis reared on winter geometrid pupae. The adultpreoviposition period (APOP), total preoviposition period (TPOP), and totallongevity were significantly longer in A. chinensis reared on winter pupae than in the other treatments.The fecundity of A. chinensis reared on spring geometrid pupae wassignificantly lower than in the other treatments. The higher intrinsic rate ofincrease of the A. chinensis reared on summer pupae (r = 0.0966 day-1) and autumn pupae (r = 0.0983 day-1) resulted in higher fecundity, shorter immatureduration, and shorter TPOP compared to the winter and spring populations. Thesefindings can be utilized to enhance and sustain biological control of E. grisescens in tea plantations.
