A survey of insects reared from seeds and fruits in a rainforest in Thailand yielded 337 specimens of Tortricidae representing 16 species. Based on this material, we present host records for the following: Hilarographa muluana Razowski complex (Chlidanotini), Archips machlopis (Meyrick) (Archipini), Cryptaspasma brachyptycha (Meyrick) (Microcorsini), Collogenes squamosa (Diakonoff) (Microcorsini), Gatesclarkeana idia Diakonoff (Olethreutini), Helictophanes prospera (Meyrick) (Olethreutini), Lobesia aelopa (Meyrick) (Olethreutini), Hoplitendemis sp. A (Olethreutini), Cryptophlebia rhynchias (Meyrick) (Grapholitini), Cryptophlebia ombrodelta (Lower), Cryptophlebia sp. (undetermined) (Grapholitini), Thaumatotibia sp. (undetermined) (Grapholitini), Andrioplecta shoreae Komai (Grapholitini), Andrioplecta subpulverula (Obraztsov) (Grapholitini), Andrioplecta (?) species (undetermined) (Grapholitini), and Cydia (?) species (undetermined) (Grapholitini). Tortricids were reared from 30 plant species representing 12 plant families, with Sapindaceae and Annonaceae supporting the greatest number of species, seven and six, respectively. Consistent with other surveys of seed- and fruit-feeding tortricids, the tribe Grapholitini represented 50% of the total tortricid species and 73% of the total tortricid specimens in the Thailand survey.
