ABSTRACT
In the laboratory of Insect Pathology of the Center for Agricultural Research (CIAP), between the months of February to June 2018, this study was conducted with the objective of determining the population increase of Zabrotes subfasciatus (Boh.) (Coleoptera; Crysomelidae) in 23 common bean cultivars. The oviposition of the insects on the seeds, the increase of the number of insects and the reduction of the weight of the seeds in the second generation were determined. In the 23 cultivars evaluated the insect reproduced, the largest increases were over Mulangri 112, P 2170, Quivicán and Milagro Villareño. The presence of Z. subfasciatus on the cultivars BAT 304 and Holguin 518 did not cause considerable losses in the period evaluated.
