The productivity of the commercial cultivars INIFAT 93 and INIFAT 94 of cowpea (Vigna unguiculata (L.) Walp.) in tobacco agroecosystems of the localities "Guane" and "San Juan y Martínez", Pinar del Río, was determined. In the latter, sampling and capture of harmful and beneficial insect species were carried out during the vegetative and reproductive phases of the crop to estimate the composition and frequency of appearance in the two cultivars. Higher biological productivity was achieved with INIFAT 94, although the differentiated response between cultivars for biomass values was more accentuated in “San Juan and Martínez”. Yield components were favored in INIFAT 94; while the lowest variability and highest efficiency in the conversion of economically useful biomass was obtained with INIFAT 93. The agricultural productivity of the INIFAT 94 cultivar exceeded that of INIFAT 93 by more than 25 % in the two agroecosystems, with values higher than 1.0 t/ha. Twenty-one species of insects associated with cowpea bean cultivars were identified, between harmful (61,9 %) and beneficial (38.1 %), grouped into 14 families and five orders, with a greater representation of Coleoptera and Hemiptera. The families with the highest species richness were Chrysomelidae and Coccinelidae. In both cultivars, 71.4 % of the identified species were observed. Empoasca kraemeri, Liriomyza trifolii, Epitrix cucumeris, Aphis craccivora, Coleomegilla cubensis, Condylostylus sp. and Diglyphus sp. presented a frequency of appearance greater than 50 %.
