Q: In this task, you are given a text of many news articles seperated by special token "|||||". Your task is to summarize them.
The kudzu bug has arrived from Asia, and it's spreading rapidly throughout the southeastern United States. Considering that the bug usually eats kudzu, an invasive plant that has displaced many native species and wreaked environmental havoc, one might be tempted to think that this isn't such a bad thing. 
  
 But there's just one problem: The kudzu bug is also rather fond of eating soybeans, and new research shows it can complete an entire life cycle on soybean plants, devastating whole fields of the legume. It also has no known natural predators in the United States. 
  
 Given the bugs' ravenous appetite and ever-expanding range, the insect is poised to create real trouble for soybean farmers nationwide, and perhaps even in other countries, said Dominic Reisig, a researcher at North Carolina State University. 
  
 The bug, native to Japan and East Asia, was first found in the United States in 2009 in Atlanta, Georgia, Reisig said. By 2010, it was only found in one county in North Carolina, two states to the north. By 2011, it was found in half of the state's counties. Last year, it was found in every county sampled. 
  
 It can now be found as far west as Mississippi and Tennessee and north to Virginia. From 2011 to 2012, the estimated cost of treating the insect in North Carolina alone increased more than tenfold, to $840,000, Reisig said. It's likely to cost more than ten times that much to treat it this year, he said. 
  
 The kudzu bug has a unique lifestyle. The first generation hatches in the spring. Then these bugs lay eggs and give rise to a second generation in the summer. These second-generation insects mature in a couple months and lay eggs that hatch in the spring. 
  
 The kudzu bug was previously thought to have just chomped away at the kudzu plant. Then some first-generation adults were found transferring to soybeans and laying eggs that grew up eating the crop. And Reisig's research has found that these pernicious bugs can survive on soybeans during all phases of their lives. His latest study was published recently in Journal of Economic Entomology. 
  
 One experiment in Georgia illustrates the impact of the bugs. The experiment looked at two fields, both infested with kudzu bugs; one field was sprayed with insecticide, while the other was left alone. The untreated field lost 70 percent of its yield compared to the treated one, Reisig said. He estimates that infestations may reduce soybeans yields by about 15 percent on average. 
  
 The good news is that the bugs are relatively easy to treat, with one application of common insecticides. But this isn't ideal, since you never want to have to spray more pesticides, Reisig said. There is currently work being done to see if a parasitic wasp—which lays eggs inside the bug's body—can be imported from Japan. But the research is still underway, and getting the necessary approval to introduce an exotic species can take years. 
  
 Meanwhile, the bug is spreading quickly, thanks to its strong flying ability. Reisig said the bugs could possibly live just about anywhere that soybeans grow, though it doesn't tolerate cold weather early in the season very well. 
  
 The insect is also a capable hitchhiker. The insects are found on tall, white objects—Reisig, as an extension specialist, often gets calls from homeowners annoyed to find a huge group of the bugs on the exterior of their white houses. Considering the bug was first found near an airfield in Atlanta, Reisig guesses that the bugs may have hitched a ride on an airplane. They are likely spreading via automobiles as well. One recent discovery of the bugs, in Mississippi, took place a long distance from the nearest known infestation. 
  
 "It looked like it jumped the whole state," Reisig said. "That was on a kudzu patch by the interstate."

 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. 
  
 Because the immature Generation A kudzu bugs have only been seen to feed on kudzu, researchers thought that the pest would not be able to migrate to northern and western parts of the United States, where kudzu doesn't grow. But now it's not so clear. 
  
 Under controlled conditions in a greenhouse laboratory, researchers at NC State found that immature Generation A kudzu bugs were not limited to feeding on kudzu – they were able to feed exclusively on soybeans, reach maturity and reproduce. 
  
 "Researchers began seeing some of this behavior in the wild in 2012 and, while those data aren't quite ready for publication, our lab work and the field observations indicate that kudzu bugs are potentially capable of spreading into any part of the U.S. where soybeans are grown. And soybeans are grown almost everywhere," says Dr. Dominic Reisig, an assistant professor of entomology at NC State and co-author of a paper on the research. "It also means that both annual generations of kudzu bugs could attack soybean crops in areas where the bug is already established, which would double the impact on farmers."

 The paper, "First-Generation Megacopta cribraria (Hemiptera: Plataspidae) Can Develop on Soybeans," is a "rapid communication" article in the April issue of the Journal of Economic Entomology. Lead author of the paper is NC State doctoral student Alejandro Del Pozo-Valdivia. The research was supported by the United Soybean Board and the North Carolina Soybean Producers Association.

A:
Kudzu plants have been choking the Southeast for years, so at first blush it would seem that the 2009 arrival of the kudzu-eating kudzu bug from Asia would be a blessing. No so much. It turns out the bugs favor a second crop as well: soybeans. And on the heels of new research, scientists fear the bugs could do serious damage to soybean farms far beyond the Southeast, reports Lab Spaces. It explains how the quirks of the bugs' life cycle are fanning fears: Eggs laid in the spring develop into bugs (Generation A) that eat only kudzu plants while they are young, and can move on to soybean plants only as they mature. These mature bugs lay more threatening eggs that hatch in summer (Generation B) and can feast on soybean crops from the get-go. Given the diet limitations of the immature Generation A bugs, researchers figured they wouldn't be able to migrate to areas without kudzu, the northern and western US. But using a greenhouse lab, North Carolina State University researchers observed immature Generation A bugs eating ... soybeans alone. The new research suggests "kudzu bugs are potentially capable of spreading into any part of the US where soybeans are grown. And soybeans are grown almost everywhere," says study co-author Dr. Dominic Reisig, who notes they bugs are likely spreading by attaching themselves to planes and cars. TakePart reports while the bug has no natural predator here, insecticides are fairly effective in wiping them out—but that obviously means dousing crops in more chemicals. Bringing in a parasitic wasp from Japan could hasten their undoing, but getting the OK to import an exotic species can take years.
