This study was conducted to identify changes of insect compositions and diversity after construction of an onshore wind farm. We investigated insect fauna and compositions between a grassland deforested by the construction and a forest located at Yeongdeok and Yeongyang, Gyeongsangbuk-do, Korea. Insects were collected using a sweeping net and light trap. A total of 11 orders, 50 families, and 246 species, and 1,076 individuals were collected at study sites. By taxonomic group, Lepidoptera species were the most frequently found with 141 species, 417 individuals (38.8%), followed by Hymenoptera (20.6%), Hemiptera (16.2%), and Orthoptera (12.3%). There were also significant differences in insect species and community compositions between sites. Creating open-field deforested forests are beneficial for some insect groups such as Hymenoptera and Orthoptera. Our results suggest that deforesting by the construction of an onshore wind farm might affect the composition and diversity of insects. Results of this study provide basic data for research on onshore wind farms.

충남 서부에 위치한 보령 지역은 트라이아스기 후기로 알려진 육성 기원의 남포층군이 널리 분포하고 있다. 남포층군은 하부로부터 하조층, 아미산층, 조계리층, 백운사층 및 성주리층으로 구분된다. 남포층군에서 산출되는 화석의 대부분은 식물 화석이며, 기타 이매패 화석, 어류 화석, 곤충의 유충 화석, 패갑류(conchostracans) 등의 화석이 산출되고 있지만, 양적으로 극히 적다. 이들 화석 중에서 체계적으로 연구가 된 것은 식물 화석뿐이고, 나머지 화석들은 전문 연구가의 부재 등에 의해 극히 미미한 연구 수준에 머물러 있다. 이번의 연구를 통해서 아미산층에서 채집된 곤충화석은 모두 107점이고, 그중에서 유충 화석이 94점, 날개 화석이 14점이다. 이들의 분류학적 연구 결과, 아미산층의 곤충화석군은 소시목, 강도래목, 날도래목, 하루살이목, 잠자리목, 바퀴벌레목, 벌목, 매미목을 비롯한 8목 11종에 이르는 유시류의 곤충들로 구성된다. 이들은 현재까지 우리나라에서 발견된 곤충화석 중 시대적으로 가장 오래된 화석이다. 유충 화석은 모두 수서 곤충의 유충화석이다. 이들의 유충은 수중생활에 적응하여 지상생활을 하는 성충과 형태적으로 큰 차이가 있는 불완전변태류 또는 외시류이다. 날개 화석은 수서곤충의 성충의 날개이고 일부는 육상 생활을 하는 곤충의 날개가 포함되어 있다. 아미산층에서 나온 곤충화석에는 육상에서 생활하는 매미목과 바퀴목도 있는데 이들은 불완전변태류에 속한다. 그러나, 똑같은 육상생활자이면서도 벌목은 완전변태류 또는 내시류에 속하는 것도 있다. 따라서 아미산층에서 산출된 곤충화석군에는 불완전변태류와 완전변태류가 섞여 있는 특징을 보인다. 이들은 실제로 같은 시대에 비슷한 장소에서 함께 생활을 했던 생물군집이지만, 서로 살던 장소가 다른 집단들이 섞여 있다는 것은 육상생활자의 일부가 죽은 후 수류에 의해 퇴적분지로 유입되어 매몰된 혼합집단으로 볼 수 있다. 현생의 하루살이목, 강도래목 등은 대표적인 유수성 곤충이고, 잠자리, 노린재 등은 대표적인 정수성 곤충으로 알려져 있다. 이들이 지층에 밀집하여 산출되는 것으로 보아 살던 장소에서 많은 퇴적물의 유입에 따른 급격한 매몰에 의해 화석화된 것으로 판단된다. 동아시아의 중생대 초기에서 보고된 곤충 화석은 양적으로도 수적으로도 그리 많지 않다. 그중에서 일본의 Mine에서 보고된 화석군이 가장 대표적이며 바퀴류(Blattaria)와 딱정벌레(Coleoptera)의 화석이 가장 큰 비율을 차지하지만, 아미산층 곤충화석군과의 공통종은 한 종도 없다. 아미산층의 곤충화석군은 비록 다양성은 쥐라기의 곤충상에 비해 떨어지지만 조성적으로는 쥐라기의 곤충상에 매우 유사하다. 육상에 사는 곤충이 화석으로 보존되기 어렵다는 것을 감안하면 아미산층에서 산출된 곤충화석은 학술적으로 매우 귀중하고 큰 의미가 있다. 보령 지역의 곤충화석은 중생대의 쥐라기와 백악기를 거쳐 현재로 이어지는 곤충 진화사의 잃어버린 고리를 이어줄 수 있는 귀중한 자료로 평가된다.

In order to investigate the response in fauna and biological communities of terrestrial insects to the vegetation encroachment on the sandbar, species composition, species diversity, functional species traits and community structure of land-dwelling insects sampled by a pit-fall trap were compared at the bare and vegetated sandbar of a typical sand-bed stream, the Naeseong Stream, Korea. Species diversity of the insects was increased but their density was decreased as the riparian vegetation encroached at the sandbar. In particular, indicator species of bare sandbar such as Cicindela laetescripta and Dianemobius csikii, were found at the bar sandbar. The insect communities were clearly classified at the bare and vegetated sandbar according to coverages of riparian plants. The food web of the bare sandbar was composed of detritus - detritivore and scavenger - predator consisted mainly of Coleoptera. On the other hand, the food web of the vegetated sandbar was composed of plants - sucking and chewing herbivore - parasitoid and predator. These results showed that biodiversity of terrestrial insects was increased, food web was changed from grazing to detritus food chain, and insect fauna specific bare sandbar disappeared as the riparian vegetation invaded on the sandbar of a sand-bed stream.

This study was conducted to identify the impact of river improvement efforts by studying terrestrial insects inhabiting at streamside locations at the Daejeon and Yudeung streams. Seven surveys were conducted from April to October on 2008 and the results were analyzed. Totally 428 species of 110 families belonging to 11 orders of insects were investigated during the course of the present study. The insects identified at the Daejeon stream belonged to 335 species, 99 families and 11 orders, while those at the Yudeung stream were of 350 species, with 98 families and 11 orders. At the Daejeon stream, D-1 and D-2 points were the sites where the most species(178 species) were identified, while at the Yudeung stream, the Y-1 point was the site where the most species(179 species) emerged. In a cluster analysis based on a similarity index, Group A(without river improvement works) and Group B(downtown passing area with river improvement works) were created. Within Group A, survey points were classified as the Daejeon stream group(the A-1 Group) and the Yudeung stream group(the A-2 Group). It was found that the emergence patterns of insects were related to regional characteristics of the streams.

The authors investigated feeding habit of river sculpin(C. poecilopus) were conducted at the Chiak streams from April 1993 to March 1994. The feeding habit of C. poecilopus was mainly acquatic insects, such as Ephemeroptera, Odonata, Plecoptera, Trichoptera, Coleoptera, Diptera, and Nematoda, teleost fishes, fish egg and terrestrial insects. Terrestrial insects in the stomach contents were found mainly in autumn, and teleost fish(Moroco oxycephalus) was in summer. Aquatic insects(Ephemeroptera, Trichoptera and Diptera) constituted the bulk of food items ingested during each season. The prey selection indices for Ephemeroptera were positively selected in summer, and negatively selected in autumn and winter, Tricoptera and Diptera were positively selected in autumn and winter, and negatively selected in summer. Additionally, analysis for stomach contents of guarding males suggests that the parental males eat their own eggs during egg guarding(filial-cannibalism).

This study was conducted to build basic terrestrial insect data for the management of the persimmon plantations in the Sangju dried persimmon agricultural area. The survey identified terrestrial insect species were 7 orders, 77 families, and 1,925 individuals of 177 species. And the number of species that appeared in each village was in the order of Seoman II Village in Naeseo Township > Seoman I Village in Naeseo Township > Soeun Village in Oenam Township. Hemiptera and Coleoptera predominated throughout the site due to the characteristics of the cultivated land. The special species were 13 Korean endemic species, 2 vulnerable (VU) species, 22 least concern (LC) species, 42 not-evaluated (NE) species on the national red list, and 2 species of ecosystem disturbance wildlife. A result of the cluster analysis identified the Ectmetopterus micantulusas the dominant species and Ceutorhynchus albosuturalisas the subdominant species. The species diversity (H') was 1.1636-1.6022, evenness (J') was 0.6748-0.7611, and dominance (D) was in the range of 0.2389-0.3252.

Terrestrial insect fauna was surveyed in the Junam wetland area, which consists of the Junam, Dongpan, and Sannam wetlands, by visual counting and pictures. A sweep net collection was conducted from May to October 2010. A neighburing artificial lotus wetland was also surveyed for comparison. A total of 5,730 insects were surveyed, representing 268 species in 85 families and 12 orders. Sixty-three species of coleopterans were surveyed, followed by 60 species of Lepidoptera, and 37 species of Hemiptera. Coleopteran individuals were 25.9% of the total insect numbers surveyed, comprising most abundant group. This was followed by Odonata, Lepidoptera, and Orthoptera at 22.3%, 15.4%, and 12.7%, respectively. In total, 197 species were surveyed in the Dongpan wetland, 175 in the Junam wetland, and 154 species in the Sannam wetlands. However, only 86 species were surveyed in the artificial lotus wetland. Galerucella nipponensis in Coleoptera, Crocothemis servilia mariannae in Odonata, and Polygonia c-aureum in Lepidoptera were the most abundant in all four wetlands. Community analyses showed that the dominance index was highest in the artificial lotus wetland at 0.25 and lowest in Junam wetland at 0.08. Diversity indices were relatively high in all wetlands at 4.48, 4.44, 4.28, and 3.87 in Junam, Dongpan, Sannam, and the artificial lotus wetland, respectively. The insect fauna similarity index was highest in the Junam and Dongpan wetlands at 0.96. The lotus wetland showed the lowest similarity of the three wetlands with values of 0.45-0.53.
