The Gyeonggi Provincial Agricultural Research and Extension Services has observed an anticipated early May emergence of exotic and brown-winged leafhoppers, attributed to warmer winter temperatures, with a hatching rate ranging from 60.0-88.9%. This development poses a significant threat to various crops, underscoring the urgency for prompt monitoring and control measures. A slight increase in the hatching rate from the previous year has been noted in Gyeonggi Province, and with the Korea Meteorological Administration predicting higher spring temperatures, there's a reinforced need for continued research and proactive strategies to mitigate the impact of these pests on agriculture.
