Resumen:
Abstract: Production of fruits of Gleditsia amorphoides (Fabaceae) and abundance of Bruchidiusendotubercularis Arora (Coleoptera: Chrysomelidae) during three consecutive years in the Southeast ofthe Formosa Province (Argentina). Gleditsia amorphoides (Griseb.) Taub. is a tree species native to SouthAmerica. It is known for its good quality wood and for its fruits that contain a rubber for industrial uses. One ofthe causes for the reduction of the production of viable seeds in forest trees is the damage caused by predatorsof fruits and seeds. The relationship between fruit production and predators is not known for G. amorphoides.Therefore, in this study, we evaluated the fruit production in this three species and the abundance of specimensof the Subfamily Bruchinae associated to G. amorphoides. The study was carried out in three localities ofthe Formosa Province in the Northeast of Argentina for three consecutive years. We found a single species ofBruchinae, identified as Bruchidius endotubercularis Arora. The results showed the existence of variability inthe production of G. amorphoides fruits between years, but not between locations. The abundance of insectsremained constant, not responding to the variation in the production of fruits between years. In this study, wereport for the first time, the occurrence of B. endotubercularis associated with G. amorphoides in Argentina.Rev. Biol. Trop. 66(3): 1046-1054. Epub 2018 September 01.
