Research finds invasive kudzu bugs may pose greater threat than previously thought
Seed Daily via SPX: The invasive kudzu bug has the potential to be a major agricultural pest, causing significant damage to economically important soybean crops. Conventional wisdom has held that the insect pests will be limited to areas in the southern United States, but new research from North Carolina State University shows that they may be able to expand into other parts of the country.
Kudzu bugs (Megacopta cribraria) are native to Asia, and were first detected in the U.S. in Georgia in 2009. They have since expanded their territory as far north as Virginia. The bugs have an interesting life cycle, which has been thought to be a limiting factor on far they can spread.
Eggs laid in the spring hatch into a first generation, which we'll call "Generation A." The immature bugs of Generation A normally feed on kudzu plants until they reach adulthood, when they have been known to move into commercial soybean fields.
These mature adults lay eggs that hatch into Generation B during the summer months. Generation B kudzu bugs can feed on soybean crops during both their immature and adult life stages, causing significant crop damage. ..
