Some features of the biology of Pauesia sp. (Hymenoptera: Aphidiidae), a parasitoid introduced into South Africa from south eastern United States against Cinara cronartii Tissot & Pepper, were studied in the laboratory and in the field. The upper threshold for development was determined as 29 �C. The minimum developmental threshold was 7,51 �C and the thermal constant was 206,19 day-degrees.
