A review of host plants for the tortricid tribe Grapholitini, with a synopsis of host utilization by genus (Lepidoptera: Tortricidae)

Resumen

A database of larval host plants for the tortricid tribe Grapholitini (Lepidoptera: Tortricidae: Olethreutinae) is presented, and larval hosts are summarized for each genus. Food plants have been reported for over 400 of the approximately 1,644 described species of Grapholitini. Of the 81 genera currently assigned to the tribe, at least one larval host has been reported for 51. Ninety-seven different plant families have been reported at least once for a species of Grapholitini, with the greatest number of grapholitines recorded from Fabaceae (168 species), followed by Fagaceae (43 species), Pinaceae (43), Sapindaceae (36), Rosaceae (30), Asteraceae (30), Euphorbiaceae (15), Rutaceae (12), Annonaceae (12), Salicaceae (11), and Cupressaceae (11). Thirty-two genera appear to be restricted, or nearly so, to specific host families, but many of these are either monotypic or are represented by exceedingly few records. Extraordinarily, entomophagy is well documented in three genera: Andrioplecta, Coccothera, and Parapammene. Two new combinations are provisionally proposed based on hosts and male genitalia: Andrioplecta magnetica (Meyrick, 1928), new combination, and A. theristis (Meyrick, 1912), new combination, both of which are currently assigned to “Grapholitini unplaced species.”
