Research efforts to protect agriculture and the environment against invasive plant pests in the United States
An invasive pest is a non-native species which can cause damage to the economy, natural resources, or human health. The invasion of these non-native species is an escalating problem worldwide. In particular, it is estimated that ca. 50,000 nonindigenous species have been introduced into the United States, many of which have caused a total of > $100 billion losses in natural and agricultural ecosystems. Recently, two invasive pests, Halyomorpha halys (Hemiptera: Pentatomidae) and Drosophila suzukii (Diptera: Drosophilidae), have emerged as serious agricultural pests in the U.S. Both species are native to Asia, however the distributions of the pests have rapidly expanded across the U.S. causing significant economic losses especially in specialty crops, presumably due to similarities in host plant complex and climatic environments between the native and new regions. In this study, a series of research efforts to protect agriculture and the environment against H. halys and D. suzukii in the U.S. are summarized and reviewed.
