The influence of cultivars, Criolla Blanca, Cuatro Estaciones and Gallega on the biology and the populational parameters of Nasonovia ribisnigri and Aulacorthum solani (L) (Homoptera: Aphidoidea) was considered at 10+/-1degreesC and 90% RH. The nimphal, pre-reproductive and post-reproductive periods of N. ribisnigri on Cuatro Estaciones were the longest but not so the reproductive. In A. solani the nimphal period was longer on Criolla Blanca and Cuatro Estaciones and as a result the reproductive was longer on Cuatro Estaciones. The intrinsic rates of increase (r(m)) of N. ribisnigri and A. solani were longer on Criolla Blanca and Gallega, respectively. According to the predominant species it would be suitable to use Cuatro Estaciones for N. ribisnigri and Criolla Blanca for A. solani in cold times.
