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. |

ABSTRACT.
The dissipation of 4 commercial pre-harvest pesticides used in two Citrus species under field conditions is presented. The influence of agroecological region, the Citrus species and weather conditions on abamectin, spinosad, imidacloprid and difenoconazole dissipation rate on fruits were evaluated. A validated ethyl acetate method coupled to liquid chromatography-tandem mass spectrometry allowed the determination of pesticide residues having recoveries of 72?115%, relative standard deviations ≤16% and quantification limits below the international Maximum Residue Levels (MRLs). After 35?40 days from pesticides spraying, all residues were below the international required MRL. For each citrus species, the influence of the agroecological region on the pesticide dissipation was assessed. Film-protected fruits against direct radiation and rain showed higher residue levels of imidacloprid and spinosad than the non-protected ones. Either for orange or mandarin, abamectin residues were detectable only at the first day after application. These findings provide useful information to state safer pre harvest intervals and to ensure food safety and compliance with good agricultural practices.
