Este trabajo permitió descubrir la existencia de simpatria entre dos especies de Curculionidae del genero Heilipus que dañan los árboles de aguacateAvocado trees are attacked by many species of phytophagousinsects,includingthestalk-,fruit-,and branch-boring curculionid weevils of the genera HeilipusGermar,ConotrachelusDejean,andCopturus Scho¨nherr.Theseinsectshaveapparentlyevolved with avocado in the center of diversification of this plant (Equihua-Mart´ ınez 2001) and have now come to be designated as quarantined pests in the commercial cultivation of avocado, constituting a limiting factor for local and international commercialization (SAGARPA 2002; Peterson and Orden 2008).Thissituationhasrequiredtheimplementation ofdiversepestcontrolstrategiesinavocadoorchards, which have successfully excluded the big avocado seed weevil, Heilipus lauri Boheman, and the small avocadoseedweevil,ConotrachelusperseaeBarber, fromMichoaca´n,Mexico’smainavocado-producing state. However, the species are present in more remote agroecosystems where management programs are virtually nonexistent, converting these areas into natural reservoirs of these weevil pests of avocado.We thank the Secretaria de Investigación y Estudios Avanzados de la Universidad Autonoma del Estado de Mexico for financial support in part to this investigation through project 3796/2014/CID
