Abstract

Understanding how plants and insects respond to abiotic factors such as temperature and light intensity is crucial for identifying the potential impacts of climate change on plant–pollinator interactions. However, studies on the effects of abiotic factors have largely focused on specific fruit crops and their associated pollinators in Korea. Therefore, this study examined changes in insect communities and pollinators visiting the flowers of Allium ulleungense, a species endemic to Korea, in response to temperature and illumination. From 2023 to 2024, stands of A. ulleungense planted in two gardens (the Plants Evolution Garden and the Allium Garden) at the Korea National Arboretum were surveyed for eight days each year (16 days in total) during the peak flowering period. On each survey day, the two gardens were surveyed twice in the morning and twice in the afternoon (1 h per session, four surveys per day), yielding 32 data collections annually and 64 in total. Analyses of insect community responses revealed that diversity and abundance increased with rising temperature and illumination. The responses differed among insect groups: syrphid flies were correlated with illumination, whereas bees were correlated with both temperature and illumination. Comparisons between the two gardens showed that insect abundance was greater in the Plant Evolution Garden with higher illumination. This study allowed us to understand how insect activity changes in response to abiotic factors (temperature and illumination). Furthermore, by accumulating data on plant–insect interactions, we aim to provide the foundational information necessary to predict the impacts of climate change.
