Many insects feed on Lotus corniculatus foliage in Uruguay. Some of them can sporadically cause severe defoliation; such is the case with some cricket species, especially under dry weather conditions. In general, plants overcome the damage and insecticide control is not frequent. When birdsfoot trefoil fields are planned for seed harvesting, two insect species become a major problem, because of the rapid increase of its populations during the flowering period and the behavior and feeding habits of both species that complicate the early detection of 
the attack. They are Epinotia aporema (Lepidoptera: Tortricidae), a bud borer, and the seed chalcid Bruchophagus platypterus (Hymenoptera: Eurytomidae). Epinotia larvae bore into the flowers sticking them together, while feeding on the reproductive structures. The seed chalcid adults lay the eggs into the pods, one per seed, and the larvae feed on the cotyledons completely destroying the newly formed seed. 
Damage of both species can be easily oversight and, in addition to this, the use of chemical control is limited for the dependency from pollinators in order to achieve the best yields. Damage assessments of these insect pests were carried out at INIA La Estanzuela for several years. The results help in designing strategies for the management of the pests.
