However, chemical control is ineffective and sometimes associated with resistance, environmental pollution, and pest resurgence, leading to the deterioration of agricultural ecosystem services. Therefore, there is a need to find more effective and safe biocontrol agents to keep this pest under the economic threshold. In that context, we installed six plots to compare the dynamics of aphid populations in coffee trees intercropped with common beans (<i>Phaseolus vulgaris</i> L., Fabales: Fabaceae) to coffee monoculture farming systems in open fields in the Southern Province of Rwanda. Results show a significant difference in infestations of coffee aphids. The population of aphids is higher in coffee monocultures than in intercropping systems. Our results also indicate that beneficial insects respond positively to the intercropping system with more species of natural enemies, mostly ladybird beetles (Coccinellidae), hoverflies (Syrphidae), and wasps (Vespidae) than in monocultures. No Hymenoptera were observed in coffee monoculture plots, indicating that common beans attract diverse natural enemies. Therefore, coffee trees intercropped with beans can help to maintain and diversify indigenous natural enemies in agroecosystems and regulate the aphid <i>T. aurantii</i>.

In such regions, insect herbivores have a shared history of interacting with wild host plants prior to crop domestication and cultivation. However, most studies evaluating the impacts of agriculture on herbivory have been conducted in geographic regions where crops have been introduced. Here, we studied how insect herbivory is related to agriculture in Mexico, which is part of the Mesoamerican center of origin. We focused on patterns of leaf herbivory across four Mexican crops (squash, beans, maize, and husk tomatoes). We tested if total leaf herbivory, as well as the composition and dominance of different types of damage caused by leaf-feeding insects, differed between domesticated crops and their wild counterparts. Overall, we found that the relationship between agriculture and leaf herbivory depends on the observed crop. Compared to their wild ancestors (or wild relatives), leaf herbivory was higher in squash and maize, lower in husk tomatoes, and similar in beans. We also found that, due to differences in damaged area and/or shifts in dominance, damage compositions varied in squash, maize, and husk tomatoes.
