  • The family Psychidae is a small group consisting of 241 genera and 1,350 species in the world. The genus Bacotia, belonging to the family Psychidae, what was established by Tutt based on the type species, Fumea sepium Speyer and Speyer, 1846. In this study, we aimed to record lichen-feeding bagworms in Korea. The genus Bacotia Tutt is reported for the first time from Korea with one newly recorded species, Bacotia sakabei Seino, 1981. All available information, including the collecting localities, host plants, illustrations of adults and genitalia are presented. A DNA barcode for precise identification of the species is also described.

Leaf Damage Symptom of Grape (Vitis vinifera) by Tea Bagworm (Eumeta minuscula) and Control Efficacies of Several Insecticides against the Eumeta minuscula (차주머니나방(Eumeta minuscula)에 의한 포도 잎 피해증상 및 몇 가지 약제의 차주머니방에 대한 방제효과)

  • Damage of tea bagworms, Eumeta minuscula was observed for the first time from grape leaves of grape (varieties: Cambell Early and M.B.A.) from a vinery at Gumho-up, Gyeongsan, Gyeongbuk on 31 August, 2012. Activity of insecticides [Bacillus thuringiensis var. kurstaki (serotype IIIa, IIIb) WP, chlorantraniliprole 5% GP, methoxyfenozide 21% SC, spinetoram 5% GP, and spinosad 10% GP] was tested on fourth instar larvae of Eumeta minuscula in laboratory. Mortality of 4th instar of Eumeta minuscula was higher when treated with spinosad 10% WG (88.7%) and spinetoram 5% WG (67.7%) sprayed with field recommended concentration using a home sprayer in laboratory. Mortality decreased as the concentration decreased, however leaf damage rate was significantly different between the one-fourth rate and the control. Spinetoram 5% WG and spinosad 10% WG showed 63.7 and 55.7% respectively mortality of fourth instar Eumeta minuscula in field. Though these two insecticides could be used for the control of bagworms on grape, a more effective insecticide needs to be found.
