Monitoring and Environment-friendly Management of Blueberry Gall Midge, Dasineura oxycoccana (Diptera: Cecidomyiidae), on Blueberry

Spatial assessment of potential areas at risk from blueberry gall midge distribution in South Korea

“…In these areas, temperature variation related to climate change would not affect D. oxycoccana suitability directly, but the moisture index would not meet the threshold for population growth due to reduced precipitation. Collectively, it was shown that the areas unsuitable for D. oxycoccana had low temperature and precipitation because D. oxycoccana occurrence tended to increase sharply from the end of May, when the average temperature and humidity began to rise (Kang et al, 2012). appropriate for the major blueberry varieties cultivated in Korea with climate change, but damage due to increased occurrence of D. oxycoccana is expected to increase.…”

“…Currently, it is distributed in North America from the Maritime provinces of Canada to Florida and from Oregon to British Columbia, and it is spreading in other countries where blueberries are cultivated, including Australia, China and countries in Europe and South America. In South Korea, the outbreak was considered to have been introduced via imported blueberries in 2010, and subsequent damage was observed in Hwaseong, Gwangju and Dangjin regions (Kang et al, 2012). Because the distribution data are essential for estimating model parameters and validating the developed model (Kriticos et al, 2015), these data were obtained from the Center for Agriculture and Bioscience International (CABI), and 33 coordinates from 16 countries were used (CABI, 2021).…”

“…It lays eggs on blueberry shoots and flower buds, causing damage when the eggs hatch into larvae (Roubos, 2009). In Florida, a large outbreak of D. oxycoccana in rabbiteye blueberry and Vaccinium ashei (Reade) defoliated 20%-80% of floral buds, causing fatal damage to the production quantity (Lyrene & Payne, 1992).Even though their first domestic occurrence was reported in Hwaseong, Gyeonggi-do in 2010, the damage caused by D. oxycoccana was reported earlier in 2008 (Kang et al, 2012). In addition, damage to blueberry cultivation areas was confirmed in Hwaseong, Gwangju in Gyeonggi-do, Cheongwon in Chungcheongbuk-do and Sangju in Gyeongsangbuk-do in 2011 (Kang et al, 2012).…”

This suggests it is possible that D. oxycoccana has already spread nationwide, which implies that it spread faster than indicated by the data from the official domestic report on D. oxycoccana.…”

“…This suggests it is possible that D. oxycoccana has already spread nationwide, which implies that it spread faster than indicated by the data from the official domestic report on D. oxycoccana. Nevertheless, the domestic habitat of the pest has not been confirmed for a relatively long period, and studies on domestic damage and control measures against D. oxycoccana have not been conducted (Kang et al, 2012).Because available resources for national-scale management of pests are limited, precautionary information on habitat variations along with climate change is necessary for efficient pest management (Taylor & Kumar, 2013). As climate is a dominant factor determining species distribution (Grinnell, 1917), climate-based prediction of the potential distribution can be used to select areas where greater attention is required for monitoring and controlling…”
