  • Fruit piercing moths were collected at every other at orchaed(16.5ha) planted with plum, peach and pear, and surrounded by forest in Gyeongnam province from jun to September in 1987. Four black light (BL) traps were lightened to attract the moths from sunset to sunrise and sweep net was also used to catch the moths on fruit and around fruit trees from 22 to 23 o'clock, 20 minutes per fruit tree species. Forty-one species, including 15 primary piercing species(PPS) and 22 secondary piercing species (SPS), from 3 families were collected and identified as fruit piercing moths. Among them, 16 species are newly recorded as fruit piercing moths in Korea. O. emarginata, L. juno, P. stuposa, C. lata and O. excavata were diminant species of PPS, comprising 86.7% of the whole PPS. Dominant species of SPS were A. ipsilon, M. turca, S. retorata, A. livida and T. oldenlandiae, comprising 80.5% of the whole SPS. The ratios of PPS to the whole fruit piercing moths collected by BL traps and net were sweep 15.2% and 79.7%, repectively. By sweep net L. juno, P. stuposa, and O. emarginata was also captured in a large numbers on peach, C. lata was on plum, and S. retorata was on pear.

  • To discriminate features of H. assulta and H. armigera, this study was done in 1983. There is 7 spots on the forewing of H. armigera but not on that of H assulta. Ratios of length and width of valves were 5.6 on H. assulta and 4.3 on H. armigera. Numbers of setae on hindtibia of H. assulta and H. armigera were 8.5, 11.4, respectively.

  • Two species of Argyresthia, A. subrimosa Meyrick and A. umbrina Liu, Wang et Li are reported for the first time from Korea. The collecting data show that A. subrimosa occurs in two remote islands, Ulleungdo and Jejudo in the country. These two local populations are compared with each other in external and genital morphology. Argyresthia umbrina is first recorded outside the type country, China. Photographs of the habitus and genitalia are provided for the two species treated here.

  • Fruit borers such as Grapholita molesta, G. dimorpha and Carposina sasakii are major pests of plum in Korea. Population densities and seasonal occurrence were monitored using the synthetic sex pheromone trap in Uiseong and Gyeongsan, two important major plum growing area in Korea. In 2010 and 2011, adults of G. molesta were caught from mid April with the peak of late April, and then undergone three more generations in Gyeongsan. Grapholita dimorpha appeared from late April and they showed three peaks until late September. Both Grapholita species occurred a few days later in Uiseong than in Gyeongsan where the latitude is $1^{\circ}$ lower. There was no difference of the phenological occurrence of C. sasakii between Gyeongsan and Uiseong, showing the same patterns of two or three peaks. Population size was in order of G. molesta, G. dimorpha and C. sasakii with 63:16:20 and 47:35:18 in Gyeongsan and 51:18:31 and 46:13:36 in Uiseong, in 2010 and 2011 respectively. There was no difference between the numbers of Grapholita species caught in the trap installed inside and outside of the orchards.

  • An unidentified moth was captured in sex pheromone traps of the oriental fruit moth, Grapholita molesta, especially at spring season in apple orchards and their vicinity. Though the captured males were similar in appearance to G. molesta males, they were easily distinguished by a matted difference in body size. Their occurrence pattern was also similar to that of overwintering G. molesta population from April to May, at which more males were captured in the pheromone traps installed in the vicinity of apple orchards than within apple orchards. After May, they were no longer captured in the pheromone traps. To investigate any larval damage due to this unidentified moth, molecular markers needed to be developed. Four PCR-RFLP markers originated from cytochrome b region of mitochondrial DNA could distinguish this unidentified moth from G. molesta.

  • We investigated the species richness of macrolepidoptera (including pyralid moths) in the evergreen broad-leaved forests of southwestern coast of Korea. The studied site was Mt. Duryunsan and its neighboring area, Haenam-gun, Jollanam-do and moths were identified and analyzed after collecting them with UV light traps from 2001 to 2004. A total number of species comprised 18 families and 489 species. We expected that the number of species would be increased when the species of microlepidoptera and butterflies were included. The family Noctuidae with 181 species was dominant in the area followed by Geometridae with 129 species and Pyralidae with 72 species. Based on number of collected individuals, Geometridae was the highest and followed by Noctuidae, Pyralidae and Drepanidae. Fifty-one percent of the total species consisted of less than two specimens in the collected sample. Monthly changes of numbers of species and individuals were examined and indices of Simpson's heterogeneity and evenness were also drawn. We briefly discussed the possibility of moth species or group of species as bioindicator for assessing the condition of forest after disturbance.

Comparative effects of nicotine and diazinon on larval mortality and activity of cytochrome P-450 monooxygenases in Helicoverpa assulta and Spodoptera exigua (담배나방과 파밤나방의 유충사망률과 cytochrome P-450 monooxygenases의 활성에 미치는 니코틴과 다이아지논의 영향)

  • This study was carried out to investigate effects of diazinon, an organophosphate, and nicotine, a plant~originated toxic chemical, on larval mortality and activity of cytochrome P-45D monooxygenases, a major detoxifwation enzyme system, in Helicoverpa assulta and Spodoptera exigua. Diazinon treatment gave a higher mortaliLy to H. assulta larvae than S. exigua larvae. In contrast to the case of diazinon, nicotine caused a higher mortahty to S. exigua than to H. assulla larvae. It was partly due to the fact that nicotine induced the actiVIty of midgut cytochrome P-450 monooxygenases (MFO) more than diazinon did in If assulta larvae. When If. aSSlllta larvae were reared on their host p\am. NicotwlIa tuoocum leaves, other componentS were mostly metabolized with the exception of dietary nicotine.

  • 옥수수를 재배할 때 가장 문제가 되는 해충은 조명나방(Ostrinia furnacalis)이다. 조명나방은 나비목 포충나방과에 속하는 곤충으로 유럽과 아메리카, 아프리카 대륙을 제외한 여러 지역에 분포하는데, 국내에서는 1924년 처음 기록되었다. 먹이로는 외떡잎식물인 옥수수, 수수, 조, 율무뿐만 아니라 피망과 같은 쌍떡잎식물도 있어 기주식물 범위가 넓은 해충으로 알려져 있다. 애벌레가 먹이식물의 줄기와 열매 속으로 파고 들어가 안에서 먹는데, 옥수수에는 잎, 줄기, 수꽃과 암술, 열매의 겉과 속에 구멍을 내어 피해를 준다. 외부에 노출되지 않고 식물의 안쪽에서 생활하는 곤충으로 관리하기에 어려운 점이 많다. 따라서 조명나방에 대한 이해를 돕고자 조명나방의 생태와 예찰방법을 소개한다.
