Abstract

Backyard crops of creole bean (Phaseolus lunatus L.) and canavalia (Canavalia ensiformis L.) were monitored in the town of Cerro Gordo, municipality of Emiliano Zapata, State of Veracruz, from September 2015 to July 2016. Symptoms of hyperplasia were found in stems and pods, caused by a complex of borers from the Tortricidae family. The morphological identification of the adult specimens by characteristics of genitalia and chaetotaxy of the larvae, as well as molecular biology identification, showed that the specimens found in beans belong to two species, Cydia deshaisiana (Lucas) and Ecdytolopha fabivora (Meyrick). Those found in canavalia belonged to C. deshaisiana and Cydia pomonella (L.), being the first report of C. pomonella in C. ensiformis. The sequences were published in the GenBank, under accession codes KX357712 (E. fabivora) and MN972449 (C. deshaisiana), presenting a coincidence of 96% at genus level, due to the lack of sequences of this species in the data base. Sequence obtained from C. pomonella specimens were published with accession code MN972450, and presented a 92% similarity with the mentioned species.
