  • We reviewed the genus $Adoxophyes$ (Lepidoptera: Tortricidae) from Korea and recognized three species of the genus. Among them, $A.$ $paraorana$ sp. nov., formerly misidentified as $A.$ $orana$ in Korea, is described as new to science. $Adoxophyes$ $orana$, a notorious pest known in most Eurasian countries for a long time, turns out to be only recently introduced or found in Korea. Photographs of the adults and genitalia of the species are provided. Specific distinction was supported by the COI barcode study.

  • Adoxophyes spp. (Lepidoptera: Tortricidae) are economically important pests of fruit trees in Asia and Europe. The geographical distribution of three Adoxophyes species, A. orana, A. honmai and A. paraorana, in Korea was surveyed using species-specific sex pheromone traps for males in 2006 and 2007. The distribution of A. orana was restricted in the midwestern area, while A. honmai was found mainly in the southern area. In contrast to these two species, A. paraorana was widely distributed. Moreover, A. paraorana coexisted with A. orana in the midwestern area, and with A. honmai in the southern area. The seasonal fluctuation of male catches was monitored with pheromone traps in 2008. In the central regions, males of A. orana and A. paraorana were captured from May to September, with peak numbers in late May, middle July, and late August. A. honmai males were trapped from late April to late September, with peak catches in middle May, late June, early August, and early September in Naju.

  • A complete control on quarantine insect pests is required for exporting domestic apples to other countries. To this end, a controlled atmosphere and heat treatment system (CATTS) has been developed as a post-harvest treatment. This study determined the CATTS conditions to control completely two lepidopteran insect pests, the smaller tea tortrix moth, Adoxophyes paraorana and the peach pyralid moth, Dichocrocis punctiferalis, which exhibit different feeding behviors. In both species, the fifth instar larvae were the most tolerant developmental stage to the heat treatment. Under CATTS conditions with 15% $CO_2$ and 1% $O_2$ for 1 h heat treatment at $46^{\circ}C$, the fifth instar larvae of A. paraorana exhibited a complete lethality, while those of D. punctiferalis underwent 88% mortality. To control completely the fifth instar larvae of D. punctiferalis, 2 h heat treatment required under the same atmosphere condition. These CATTS treatment effects were confirmed against over 3,000 fifth instar larvae of each species infesting apples. This study demonstrates that the longer exposure to CATTS conditions is required for the complete disinfestation of the internal apple feeder compared to the non-internal apple feeder.

  • Landscape composition and structure are important factors determining biological diversity including pests and natural enemires in agricultural ecosystem. This study was conducted to indentify effect of landscape composition on occurrence of lepidopteran pest population in Geochang, Gyoungdnam. For this, orchard characteristics and management practices were surveyed in 80 conventional apple orchards in Geochang, Korea, along with the monitoring of pest population densities. The landscape features of each surveyed orchard also obtained by extracting information from the public-service map. Grapholita molesta was the most dominat and damaging pest followed by Phyllonorycter ringoniella and Carposina sasakii in trap catches. Adoxophyes paraorana occurrences were low. Farmers spray insecticides and fungicides ap. 12.4 times per year respectively while acaricides were sprayed 2.4 times. Major landscape features such as surrounding apple orchard or paddy field did not influence the pest populations but presence of plum, peach, wild peach, graph, and even abandoned orchards significantly resulted in higher pest population mostly on G. molesta. C. sasakii population was higher in orchards with grape, peach, and P. ringoniella with peach, grape, abandoned orchards and jujube. Results highlight the need of landscape management not only for the rural amenity but also for increasing functional diversity of agroecosystem as well as reducing pest population.
