The interaction of herbivores vectors and their natural enemies associated with the interior of crops and border vegetation in Latin America is little studied. Therefore, the objective of this work is to list species of phytophagousinsects of the suborders Auchenorrhyncha and Sternorrhyncha, as well as parasitoid wasps of the families Dryinidae, Eulophidae, Mymaridae, and Trichogrammatidae found on important crops such as: corn, avocado, berries, andcitrus. The capture of vector insects was carried out using diverse collection methods on host plants in Mexico (corn, avocado, citrus, and berries) and Argentina (corn). Subsequently, both egg and adult parasitoids were obtained from individuals who presented evidence of parasitism at any stage of development. As a result, a list of hosts was generated, including Dalbulus spp., Stirellus bicolor, Exitianus picatus, Diaphorina citri, and Peregrinus maidis. At the same time as of its natural enemies (parasitoid wasps) such as: Tamarixia radiata, Gonatopus spp., Anagrus spp., and Paracentrobia spp. The agroecological dynamics at different trophic levels and importance of preservinguncultivated areas to guarantee the reduction of diseases transmitted to crops by these insects carrying harmful agents are discussed.
