The remains of parasitized lepidopterous larvae collected in sweet potato fields in Fujian, China, were examined and found to consist of 3 types: shrivelled, empty-skinned and distended-and-twisted. The shrivelled type included the following: larvae parasitized by eulophids; 2nd-instar larvae of Agrius convolvuli (L.) (Herse convolvuli) parasitized by Charops bicolor (Szepl.); and 4th-instar larvae of Brachmia triannulella (H.-S.), 2nd-instar larvae of A. convolvuli, and last instar larvae of Swinhoea vegetus (Swinh.) (Cretonia vegeta), Creatonotos transiens (Wlk.), a noctuid and a ctenuchid parasitized by Apanteles spp. The empty-skinned type included; 3rd-instar larvae of B. triannulella parasitized by Apanteles sp., the 4th-instar larvae of B. triannulella parasitized by Macrocentrus sp., and the last instar larvae of Swinhoea vegetus parasitized by a braconid. The twisted type of larval remains was typical of last-instar larvae of Acanthoplusia agnata (Stgr.) (Plusia agnata) parasitized by Litomastix [Copidosoma] truncatella (Dalm.). A key based on the structure of the head capsule of the dead larvae is provided. none
