Megachile rotundata (Fab.) as a potential agro-environmental conservation strategy for alfalfa seed production in Argentina por Renzi Pugni, Juan Pablo, Coito, Carlos, Reinoso, Omar Juan, Quintana, Matias, Garcia, Flavia Carina, Cantamutto, Miguel Angel

“…The continued importation of alfalfa seed carries a serious risk of unintentional introductions, such as contamination by genetically engineered (GE) alfalfa. We evaluated: (i) GE contamination in the main alfalfa seed production area of Argentina by analysing 263 conventional bulk seed lots (~900 tonnes) and feral populations (n = 49) over a 5-year period (2016–2021); and (ii) the location of alfalfa fields near natural vegetation formations as a pollination management strategy to increase the local seed production. …”
