Abstract The objective of this work was to assess sources of resistance to leafminer in melon plant germplasm and identify the most recommended variables associated with antixenosis resistance. A total of 32 genotypes were evaluated for resistance by antibiosis: larval and pupal viability, and antixenosis: mines per leaf, per plant, and per area, in choice and no-choice tests in the laboratory and through morphological characteristics. 'Festival' hybrid is the most promising source of resistance to the leafminer due to antibiosis; however, none of the evaluated genotypes show antixenosis. Mines per area is the most reliable variable to evaluate resistance to leafminers by antixenosis in melon germplasm.
