Terrestrial Insect Fauna of the Junam Wetlands Area in Korea

Abstract

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. 지구상에는백만 종이 넘는 수의 곤충 종이 기재되어 있으며, 생태가 매우 다양하고 숫적으로나 양적으로 먹이 연쇄에서 우 위를 차지하고 있다(Gullan and Cranston, 2005). Norman Myers는 침몰하는 방주(The Sinking Ark)에서 해마다 4만 여종 의 생물종이 사라지고 있으며(Norman, 1979), 지구상의 종 중 3/4이 2200년까지 멸종하거나 멸종위기에 처하게 되는데, 한 식 물이 사라질 때마다 평균 10~30종류의 다른 종들도 무너져 내린 다고 추정하였다(Richard, 2005). 생태계는 이처럼 그물과 같아 서 드물거나 하찮게 보이는 종이라 해도 다른 종들과의 상호작

Insect diversity in Gonggeom‐ji, the first protected paddy field wetland in Korea

“…It shows the similarity of the two communities based on the collected species. When the communities are less than 20% similar, they are heterogeneous, and homogeneous when they are 80% or more similar (Ahn & Park 2012; Whittaker 1956). As a result of the similarity indices based on sites and seasons, nine cases of similarity indices with 0.2 or more were identified.…”

Faunistic analysis of insects of Deva Vatala National Park and agroecosystem of Gujrat Pakistan

“…Species diversity has been under perils due to anthropogenic changes in the landscapes resulting in the modification of the habitat (Turner 1989;Gibbs & Stanton 2001;Wagner & Edwards 2001). To understand species distributional patterns in different landscapes, insect fauna has been studied at local and regional levels (Cho et al 2008;Ahn & Park 2012;Lim et al 2013;Rafi et al 2017).…”
