The present studies deal with life tables and intrinsic rate of increase of Cotesia flavipes (Cam.), an internal larval parasitoid of Chilo partellus (Swin.). The mated female had an average of 5.8 days ovipositional period and produced an average of 70.5 adult progeny with sex ratio 1.28: 1 (m: f). The maximum mean progeny production per day, mx was 15.6. The innate capacity of increase was 0.176 per female per day and population multiplied to 30.72 times in mean generation time of 19.45 days. Zusammenfassung Lebenstafeln und innere Vermehrungsrate von Cotesia flavipes (Cam.) (Hymen., Braconidae), eines Larven‐Parasitoiden bei Chilo partellus (Swin.) (Lep., Pyralidae) Die befruchteten Weibchen von C. flavipes hatten eine Eiablegezahl von 5,8 Tagen und produzierten i.M. 70,5 adulte Nachkommen mit einem Männchen:Weibchen‐Verhältnis von 1,28: 1. Die maximale mittlere Nachkommenerzeugung pro Tag betrug 15,6. Die Vermehrungskapazität pro Weibchen pro Tag betrug 0,176. Die Population vermehrte sich um das 30,7fache in einer mittleren Generationszeit von 19,5 Tagen.
