  • 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.

  • This study investigated the species of leafrollers in apple orchards and nursery farms in Gyeongsangbuk-do for three years from 1998 to 2000, and also examined the occurrence and damage of leafrollers in commercial apple orchards in 5-6 cities and districts for 10 years from 1992 to 2001. Total seven species of tortricidae were found in the apple orchards, which were Adoxophyes orana, Archips breviplicanus, Rhopobota unipunctana, Choristoneura longicellana, Acleris fimbriana, Ptycholoma lecheana circumclusna and Archips subrufanus. Among them, A. orana was dominant species every year, and A. breviplicanus and R. unipunctana occurred with a high density in one or two farms in some years. The dominant species in the 1980s were A. breviplicanus and R. unipunctana, but it was considered that dominant species have been changed in the late 1990s. According to the result of leafroller damage in commercial apple orchards for 10 years, the mean fruit damage rate was $0.67\%$. Fruit damage was observed frequently between August and October by third-generation larvae.

  • This study investigated the efficiency of mating disrupters for the control of Grapholita molesta(Busck) and Adoxophyes orana in pear orchards. G. molesta was shown 4 peak occurrence, which were different according to treatments. In conventional control, many moths were captured in mid and late April and peaks occurred in mid June, August, and early-mid September. In the non-control treatment, there were low populations in April. A. orana also appeared to 4 peak in 2007. Moths were rarely captured in mating disrupter treatment but many were captured in both the non-control and in conventional treatment. A. orana damage differed significantly between mating disrupter use and conventional control in 2006. Especially, the difference was significant between conventional control and mating disrupter to leaf damage in August, and there were similar results in the damage by G. molesta in the shoots and fruits.

  • Adoxophyes spp. are the major rests of a pear. The larvae attack both leaves and fruits. (Z)-9-tetradecenyl acetate (Z9-14:Ac), (Z)-11-tetradecenyl acetate (Z11-14:Ac), (E)-11-tetradecenyl acetate (E11-14:Ac) and 10-methyldodecyl acetate (10me-12:Ac) have been reported as the sex pheromone components of the genus Adoxophyes. Our objective was to determine the difference in sex pheromone composition of three different A. spp. populations each from Cheonan, Sangju, and Naju area orchards in Korea. Gas chromatography (GC) analyses of pheromone gland extracts of virgin females confirmed the presence of two compounds (Z9-14:Ac and Z11-14:Ac) in Cheonan and Sangju populations, and four compounds (Z9-14:Ac, Z11-14:Ac, E11-14:Ac and tome-12:Ac) in Naju population. The Z9-14:Ac and Z11-14:Ac were detected in the ratio of 80:20 in the Cheonan population and 3:97 in the Sangju population. Females of Naju population produced sex pheromone blend consisting of Z9-14:Ac, Z11-14:Ac, E11-14:Ac and 10me-12:Ac at a ratio of 31:62:6:1. Field trapping tests in pear orchards with Z9-14:Ac and Z11-14:Ac indicated that maximum captures of the male were obtained with traps baited by 80:20 in Cheonan, 10:90 in Sangju, and 30:70 in Naju. These results suggest that there are remarkable geographical variations in the sex pheromone composition of A. spp. in pear orchards in Korea, and taxonomic classification of these species must be carefully assessed.

  • In this study, 5 species (Tetranychus kanzawai Kishida, Endoclyta excrescens (Butler), leaf roller caterpillar (Adoxophyes orana Fisher), Anomis mesogona (Walker), and Aulacaspis rosae (Bouche)) were found in Rubus coreanus Miquel in Jeonbuk province, from 2006 to 2008. T. kanzawai appeared in mid-May and showed three peaks in late June, mid-July, and late August. Its density was over 10 adults per leaf. A. mesogona appeared in mid-June and showed two peaks in late July, and early October. Of the 28 insect pests in pre-harvesting, the 7 main species were T. kanzawai, T. urticae, A. orana, Lygocoris lucorum Meyer, Frankliniella intonsa (Trybom), Psylliodes punctifrons Baly and Motschulskyia serrata (Matsumura). Of the 19 insect pests in after-harvesting, the 6 main species were T. kanzawai, E. excrescens, A. mesogona, A. orana, P. punctifrons and A. rosae. Growth of R. coreanus decreased when insect pests were not managed and yields decreased approx. 7% a year. Management of insect pests in field using pesticide was not different.

  • 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.

  • Seasonal occurrences of three Tortricinae species were monitored at persimmon orchard in Changwon city ($35^{\circ}$09'18.16"N $128^{\circ}$34'43.63"E), Gyeongnam, Korea, by using sex attractant traps in 2012 and 2013. The two years of monitoring revealed that Adoxophyes honmai and Homona magnanima occurred four times a year, and Neocalyptis angustilineata did three times. Peak occurrence of A. honmai was recorded in mid-May, from early to mid-July, from late July to early August, and from mid- to late September for the generation, respectively. H. magnanima population peaked during mid- to late May, mid-July, from late August to early September, and from late September to mid-October for the generation, respectively. N. angustilineata showed three clear peaks from late May to early June, in late July, and from early to mid-September for the first, second, and third generation, respectively.

  • Synthesis and biological activity test are described for the (Z)-9-tetradecen-1-yl acetate(1) and (Z)-11-tetradecen-1-yl acetate(1) and (Z)-11-tetradecen-1-yl acetate(2), the sex pheromone of the summer fruit tortrix moth, Adoxophyes orana. 8-Bromoctan-l-ol THP ether was prepared from 8-bromoctan-l-ol. The lithium anion of 1-hexyne was alkylated with 8-bromoctan-l-ol THP ether gave 9-tetradecyn-l-ol THP ether. Catalytic hydrogenation over Pd/BaSO4 followed by deprotection afforded (Z)-9-tetradecen-l-ol. Acetylation gave (Z)-9-tetradecen-1-yl acetate(1). l0-Bromodecan-l-ol THP ether was obtained from l0-bromodecan-l-ol. In liquid ammonia with THF and HMPA as cosolvents, sodium acetylide could be alkylated with 10-bromodecan-l-ol THP ether to give 11-dodecyn-l-ol THP ether. 11-Dodecyn-l-ol THP ether was then treated with n-BuLi in THF to give the lithium acetylide, which was alkylated with bromoethane to afford 11-tetradecyn-l-ol THP ether. Catalytic hydrogenation, deprotection, and acetylative gave (Z)-11-tetradecen-1-yl acetate(2). The synthetic pheromone thus obtained was attractive to the males of the summer fruit tortrix in the field.
