Agricultural ecosystem is recognized as a space for providing a variety of services, in addition to the food production that
it originally encompassed, such as water purification, biological habitat, air purification, soil conservation, and landscape
development. The construction of greenhouses in agricultural landscapes can cause deterioration of ecosystem services because
of the increase of impermeable area and loss of biological habitats. This study aimed to compare insect diversity between
different types of constructed greenhouses and paddy ecosystems. The target study area was selected by considering the
distribution status of horticultural complexes and was classified as Single Vinyl Greenhouse, Multi Vinyl Greenhouse or
Glass Greenhouse and they were compared with four paddies. The study locations were in Gu-Mi, Bu-Yeo, Ginje and Jin-Ju.
A total of 2,333 individual insects belonging to 9 orders, 38 families, 76 genus, and 80 species were collected. The composition
of orders was Hemiptera (22.37%), Coleoptera (18.42%), Hymenoptera (14.47%), Orthoptera (11.84%), and Diptera
(10.53%). The average number of collected species were in the order Paddy (39.38 species) > Single Vinyl Greenhouse (35.50
species) > Multi Vinyl Greenhouse (22.50 species) > Glass Greenhouse (24.00 species). The Diversity Index (H′) was Paddy
(4.76) > Single Vinyl Greenhouse (4.57) > Multi Vinyl Greenhouse (4.12), and Glass Greenhouse (4.12). The Richness Index
(RI) was Paddy (7.72) and Single Vinyl Greenhouse (7.03) > Multi Vinyl Greenhouse (4.99) and Glass Greenhouse (5.32).
From our results, it can be seen that the biological diversity features of insects decreased when greenhouses are constructed.
However, Single Vinyl Greenhouse is noted to promote insect diversity more than that by Multi Vinyl Greenhouse and Glass
Greenhouse. Hence, when constructing greenhouses, it is necessary to consider insect habitat to conserve insect diversity.
