Damage caused by weevils or bruchids in mesquite plants (Prosopis laevigata), in the municipality of Durango was established by infestation index. Immature and mature pods were obtained from 22 bushes during the months of June to September 2013. The pods were placed in emergence chambers, maintained at a temperature of 35±2°C and 70±10% RH, until adults were obtained. In June, 1,761 immature pods were obtained of which 76% were damaged (perforations); in August 713 mature pods were obtained with 90% damage. Observed bruchids species feeding on the pods and seed of mesquite were Algarobius prosopis and Mimosestes amicus (Bruchinae) with relative abundance of 76 and 19% respectively and an average infestation index of 83,2% on pods. Natural enemies that were present were the parasitoids Urosigalphus sp. (Braconidae) and Horismenus missouriensis (Chalcidoidea: Eulophidae) with 2% relative abundance. From the total 105 pods damaged by insects, 1, 188 seeds had 69, 2% bruchid damage. Bruchids control is necessary in order to be able to obtain benefits from the mesquite pods and this can be done mainly through parasitoids that are associated with them.
