동소동속종인 팥나방(Matsumuraeses phaseoli)과 어리팥나방(M. falcana)(나비목: 잎말이나방과) 사이에 교잡 가능성을 알아보기 위해서 실험실에서 인위적으로 두 종을 교잡시켰다. 두 종의 암수를 교차하여 교미시켰을 때, F1 잡종세대가 발생하였다. 두 잡종세대 집단을 집단 내 및 집단 간 암수를 교차하여 교미시킨 경우들에서, 팥나방 암컷과 어리팥나방 수컷이 교잡되어 생성된 F1 잡종세대 집단(H집단)의 암컷이 같은 집단의 수컷 혹은 다른 집단의 수컷과 교미되었을 때, F2 후대를 거의 생성하지 못했다. 다른 집단으로 만들어진 F2 세대는 집단 내 교미에서 F3 세대를 생성시켰다. F1 잡종세대 집단 암수와 팥나방 혹은 어리팥나방 암수를 각각 교차하여 교미시킨 역교잡 8개 집단 중에서도 H집단의 암컷과 짝지어진 어미세대 수컷 집단 2개는 전혀 산란하지 못했다. 후대가 생성된 다른 6개 집단은 모두 집단 내 암수 교미에서 역교잡 F2 세대를 생성하였다. 이 결과는 팥나방 암컷과 어리팥나방 수컷이 교미하였을 경우 F1 후대잡종을 생성할 수 있으나, 이 F1 후대잡종 암컷은 불임이 되는 것을 나타냈다. 결과적으로 두 종 사이에 접합후 생식단계에서 부분적인 생식격리가 발생할 수 있는 것을 나타냈다.

가는잎말이나방족은 나비목 잎말이나방과의 잎말이나방아과에 속하는 그룹이다. 전세계적으로는 1,000여 종 (Brown, 2005)이 기록되어 있으며, 국내에는 41종(Byun et al, 2009)이 보고되어 있다. 이들은 전 세계적으로 분포하며 구북구지역에서 가장 많은 종이 알려져 있다. 가는잎말이나방족에 속하는 종들은 유충시기에 기주식물의 줄기나 뿌리에 식입하거나, 종자 또는 과실을 가해하는 습성으로 인해 일부 종들은 중요해충으로도 알려져 있다. 잘 알려진 해충으로는 포도와 인동덩굴 등을 가해하는 버찌가는잎말이나방이 있다. 본 연구에서는 우리나라에서의 가는 잎말이 나방족의 연구현황을 정리하고 향후 집중적인 연구가 필요한 분류군들을 제시하고자 한다.

본 연구를 통해 Dactylioglypha tonica (Meyrick, 1909) 종을 기반으로 Dactylioglypha속을 국내 최초로 보고한다. Dactylioglypha속은 잎말이나방과의 애기잎말이나방아과에 속해 있는 그룹으로 현재까지 전 세계적으로 5종이 동구북 구, 동양구 및 호주구 등지에서 보고되어 있다. 이번 연구를 통하여 우리나라에서는 제주에서 서식하는 것이 확인되었 다. 본 연구에서는 Dactylioglypha속에 대해 개괄적으로 소개하고 D. tonica (Meyrick, 1909)의 외부형태적 특징, 기주식물 및 분포적 특성 등을 정리하여 제시하였다.

Grapholita molesta (Busck) is a major pest of stone fruits. Immature fruits of apricot and plum are well known food source during early summer for G. molesta, but those immature fruits have rarely been evaluated. Thus, we assessed biological and behavioral attributes of G. molesta when provided with immature fruits of apricot and plum in laboratory. The initial response rate (when larva reached to the center from release point in Y-tube olfactometer) of first instar was not different between apricot (70.0%) and plum (60.0%) of which sugar content was more on plum (5.92 brix in apricot and 7.30 brix in plum). However, pupal weight was less in apricot (7.5 mg) than in plum (11.4 mg), and this might be affected by difference in hardness of the fruits (17.2 N on apricot and 13.3 N on plum). The preoviposition period was also longer in apricot (6.3 d) than plum (3.6 d), and fecundity was lower on apricot (64.5) than on plum (135.0). Therefore immature plum fruit would be better food source for G. molesta than apricot during early summer.

A total of 53 nontarget species representing six orders of insects were captured in the codling moth surveillance traps placed in Korea over the last eight years. These included 20 species (37.7%) of moths (Lepidoptera) belonging to 9 families of which 9 species were tortricids, 12 species (22.6%) of beetles (Coleoptera) belonging to 10 families, 11 species (20.8%) of flies (Diptera) belonging to 7 families; 4 families of true bugs (Hemiptera) including one species of Anthocoridae (9.4%); 1 family of Hymenoptera including 2 species of Formicidae (3.8%) and 1 family of Neuroptera including 3 species of Chrysopidae (5.7%). A list of the species of nontarget insects captured in the codling moth surveillance traps is provided. A brief diagnosis and photographs of Aterpia issikii Kawabe, the tortricid moth newly documented in Korea are provided.

Genus Eupoecilia is one of the group of the family Tortricidae, comprising 37 desciribed species in the world. Among them, 29 species are reported from the Oriental and Palearctic regions. The genus has been well known about the specific biology with showing the larval feeding in the stem or flower of the host plants. In Korea, the genus Eupoecilia are reported with 5 species up to date as follows: E. ambiguella (Hübner), E. angustana (Hübner), E. citrinana Razowski, E. inouei Kawabe, and E. kobeana Razowski. This study was conducted to review the genus Eupoecilia belonging to the family Tortricidae in Korea. In this study, totally, six species of the genus were enumerated with one new species candidate, Eupoecilia koreana sp. nov., on the previous literatures. All available information including synonymies, host plants and distributional ranges for each species is provided.

The genus Archips is a large group of the family Tortricidae, which includes 136 species in the world. In Korea, 17 species of the genus Archips have been reported up to date. The genus has difficulty in morphological classification with the species because of the sexual dimorphism between male and female. However, the study of the genus Archips with the morphological differences of both sexes has not been studied in Korea. Also, some species are known to pests of agricultural and ornamental plants. In this study, adult and genitalic structure are examined and illustrated. Also, the distributional ranges and collecting localities are provided. And the additional molecular data is necessary because of the ambiguous external characters. So, the result of the DNA barcoding were added.

To find best humidity condition for the use of Beauveria ARP14 against Grapholita molesta (Busck), first instar of G. molesta was treated with three conidial concentrations (1×107, 1×108, and 1×109 conidia/ml) in three different relative humidities (RH; 55, 75, and 95%). Mortality varied depending on concentration and humidity. Mortality in 95% RH was 1.5 and 2.7 times higher than 75 and 52% humidity at 1×109 conidia/ml and 16 hours after the exposure. However, the mycosis rates after 14 days were all not different among the treatments. In conclusion B. bassiana ARP14 could be most effective when applied higher at RH condition.

This study was conducted to clarify the faunistic information of the genus Choristoneura in Korea. The genus Choristoneura belongs to the tribe Archipini of the family Tortricidae, including 46 species in the world. Among them, Choristoneura albaniana (Walker) is the only one species with a Holarctic distribution (Dang, 1992; Fagua et al., 2014). In Korea, 7 species of the genus Choristoneura have been reported up to date. But taxonomic location of some species in the genus are still confused: e.g. transfer of Choristoneura evanidana to Archips; Choristoneura simonyi to Xenotemna and so on. Also, it is necessary to identify correctly the genus Choristoneura, especially known as the forest pest. In this study, we rearrange and re-place the species, including nomenclatural changes according the current study.

Genus Cochylidia, belonging to the tribe Cochylini under the family Tortricidae, consists of small-sized moths, which is one of the small group with only 11 described species until now (Brown 2005; Sun & Li 2012). Recently, Brown (2005) listed eight species and one subspecies. Later, three species were added to the genus by Sun & Li (2012) from China. In Korea, Park (1976) reported the genus Cochylidia with three unrecorded species, C. contumescen Meyrick, C. richteriana Fischer von Röslerstamm, and C. subroseana Haworth from Korea. Later, Byun et al. (1996) reported two additional species from Korea: C. heydeniana Herrich-Schäffer and C. moguntiana Rösler. Recently Byun et al. (2017) reported the genus in Korea with two new species, C. flavifasciatus Byun and C. hallasanensis Byun. In this study, we provide the checklist with its external characteristics, localities, and images of adults and genitalia.
