Abstract :The study was carried out to determine major lepidopteran pests of sweetpotato crop in Hatay province located in the Eastern Mediterranean region of Turkey, as well as population development of new record species Helcystogramma triannulella insert ignore into journalissuearticles values(Herrich-Schäffer); insert ignore into journalissuearticles values(Gelechiidae); between 2012 and 2013. As a result of field observations, four lepidopteran species, Hydriris ornatalis insert ignore into journalissuearticles values(Duponchel); insert ignore into journalissuearticles values(Crambidae);, Aedia leucomelas insert ignore into journalissuearticles values(Linnaeus); insert ignore into journalissuearticles values(Noctuidae);, Agrius convolvuli insert ignore into journalissuearticles values(Linnaeus, 1758); insert ignore into journalissuearticles values(Sphingidae); and H. triannulella were determined. This document is the first report of H. triannulella for Turkey, and, its population development was studied in the second year. The larval population of H. triannulella in the experimental plot began to increase in the end of July and reached its peak in mid-August. During the study, predators, Nabis viridulus Spinola insert ignore into journalissuearticles values(Hemiptera;Nabidae);; Hippodamia variegata insert ignore into journalissuearticles values(Goeze);, Stethorus gilvifrons insert ignore into journalissuearticles values(Mulsant);, Oenopia conglobata insert ignore into journalissuearticles values(L.);, Scymnus  interruptus insert ignore into journalissuearticles values(Goeze);, Scymnus mediterraneus Khnzorian insert ignore into journalissuearticles values(Coleoptera; Coccinellidae); were determined in the folded part of the leaves, and parasitoids, Compsilura concinnata insert ignore into journalissuearticles values(Meigen 1824); insert ignore into journalissuearticles values(Diptera; Tachinidae); Apanteles sp., and Chelonus sp. insert ignore into journalissuearticles values(Hymenoptera; Braconidae); were obtained from the larvae in the laboratory.
