본 연구는 벼 화분에 잔류한 네오니코티노이드계 약제가 꿀벌 봉군 내로 유입하여 만성적으로 피해를 주는지 에 대해 실험적으로 검증하고자 한다. 벼 꽃 개화기에 맞춰 논 인근의 세 지역에 각 6개 봉군을 설치하였다. 3개의 지역 중 두 지역은 벼 꽃 개화기 항공 방제 수행지역이고, 1개 지역은 미수행 지역이다. 지역마다 봉군 3개에는 채분기를 설치하여 벌통 내 화분 유입을 차단한 그룹과 미설치 그룹 간 봉세와 꿀벌 면역 및 수명 관련 유전자 발현량을 비교하였다. 약제 방제가 수행된 지역에서 채분기를 설치한 봉군의 봉세는 미설치 봉군보다 상대적으 로 강한 것을 확인하였다. 또한, 약제 처리 지역에서 채분기 설치 봉군에서 채분기를 설치한 봉군의 봉세는 미설치 봉군보다 상대적으로 강한 것을 확인하였다. 또한, 약제 처리 지역에서 채분기 설치 봉군에서 채집된 꿀벌의 면역 및 수명 관련 유전자 발현량이 미설치 그룹과 차이가 있는 것을 확인하였다.
토양에 활용되는 유기농업자재(퇴비, 유황)가 굼벵이 생육 및 생존에 미치는 영향을 알아보기 위하여 생육시험을 수행하였다. 먹이는 참나무발효톱밥을 이용하였으며, 가축의 퇴비와 유황을 일정비율(0.3, 1, 3, 10 %) 섞어 사육하였다. 시험곤충은 흰점박이꽃무지 2령 유충을 사용하였다. 사육 시 나타나는 생장율 차이를 비교하여 흰점박이꽃무지 유충의 발육 특성을 조사하였다. 참나무발효톱밥으로만 사육한 개체에 비해 유황을 혼합한 경우, 유황의 비율이 높아질수록 생중량의 증가율이 낮아지는 것으로 나타났다. 가축퇴비(우분 40%, 돈분 10%, 계분 5%)를 배합하여 사육한 경우, 참나무발효톱밥에 10% 퇴비를 배합하였을 때, 21일 후 생중량이 평균 4.18배 증가하는 것을 확인하였다.
Three species of the genus Glaucocharis Meyrick (Lepidoptera, Crambinae) are reported for the first time from Korea: G. melistoma (Meyrick), G. rosannoides (Bleszynski), and G. vermeeri (Bleszynski). The description, distribution, image of the adults, males, and females genitalia are provided. Also, checklist of the genus Glaucocharis from Korea is present.
The genus Micrerethista Meyrick, 1938 belong to the subfamily Harmacloninae, comprises 11 described species for the world. Adult are usually very small to medium in size (wingspan, 4-16mm). The principal apomorphy of this genus, the denticulate projection of the aedeagus, easily distinguishes it from most Harmacloninae. In this study, we dealt with the genus Micrerethista is newly recorded from Korea for the first time, with one species.
Illustrations of adult and genitalia are presented.
The genus Ypsolopha Latreille 1796, belongs to the family Ypsolophidae, small to medium sized micro-moth, with more than 140 described species around the world. More than 70% of the species are described from the Palearctic and Oriental Regions (Jin et al., 2013). Major taxonomic study of Ypsolopha carried out by following scholars. In the end of 18th to early of 20th century, Fabricius (1798), Hübner (1826), Agassiz (1846), Walshingham (1881, 1889), Busck(1903, 1906) and Meyrick (1914-1937). Furthermore, Moriuti (1964, 1977) studied total 17 Japanese Ypsolopha species and he divided 3 groups which based on fore- and hind- wing venations and shape of labial palpus.
The first systematic study of the genus Ypsolopha carried out by K. T. Park (1983), discovered with four species, Ypsolopha blandella (Christoph), Y. yasudai Moriuti, Y. strigosa (Butler), Y. acuminata (Butler) in ‘Illustrated Flora & Fauna of Korea vol. 27 Insecta (Ⅸ)’ and ‘Check List of Insects from Korea’. After than, Ypsolopha longa Moriuti was discovered by Jeong et al.(1995). In 2001, Byun and Park, they described new species, Ypsolopha nigrimaculata Byun and Park. At the same time, Byun and Bae reported 3 newly recorded species; Y. cristata Moriuti, Y. japonica Moriuti, Y. parenthesella (Linnaeus). Up to date, 14 species have been recorded from Korea by Sohn (2010, 2011) with Y. amoenella (Christoph), Y. asperella (Linnaeus), Y. contractella (Caradja) and Y. acerella (Ponomarenko and Sohn). In the present study, we identified 14 species belonging to the genus, with some unidentified species. The materials examined come from the collection of Incheon National University.
The Sphingidae are a family of moths (Lepidoptera, Bombycoidae), commonly known as hawk moths. The hawk moths form a family of over 1500 species of small to very large moths (40-150mm) occurring on all continents except Antarctica. The most conspicuous aspect of sphingid biology is the capacity of the moths for fast, long distance, and often migratory flight. Sphingidae adult are appropriately shaped with narrow wings and a fusiform abdomen. Sphingidae is very popular group with both amateur and professional naturalists, but the taxonomic study of the Sphingidae in Cambodia has been done by a few foreign entomologists. In the present study, we were collected 12 times from Cambodia in 10 area for 6 province. As the results of this study, about 455 species of 289 genera of 18 families belong to Lepidoptera (NIBR, 2009-2014). Of which, about 60 species of 30 genera of family Sphingidae were identified from Cambodia. Most of them are recorded for the first time in Cambodia.
