Melanoplus differentialis (Thomas, 1865) is a widely distributed Orthopteran species in North America, including the United States and Mexico. Known for causing damage to various crops such as vegetables and grains throughout its lifecycle. In South Korea, it has been observed concentratedly in the vicinity of the Onsan National Industrial Park in Ulsan and was designated as “Ecosystem Disturbing Species” by Ministy of Environment in 2020. This study aims to present foundational data on pest management strategies for Melanoplus differentialis identified within the Onsan National Industrial Park. Through collaborative efforts between the National Institute of Ecology, related agencies, and tenant private companies from 2020 to 2023, we will demonstrate the reduction in habitat area as a result of proactive pest control measures.
