After the tragedy of September 11, 2001 established the Ministry of Homeland Security, and hundreds of agricultural scientists have new challenges. According to experts, it cost U.S. billions of dollars: hit vineyards in California and Florida citrus orchards, prices for fresh herbs, increased use of pesticides.

"… As a result of losing everyone in the country", — stressed entomologist Mark Hoddle from University of California at Riverside. Officials have begun to recognize the excesses and started to correct their mistakes.

Stop invasive species is very difficult. Pests and their larvae enter the country with plants (including flowers), fruit, vegetables, grains and other things (such as the Italian tile found beetles). Some craftsmen live in wooden pallets, ubiquitous in warehouses and terminals. Of course, it is always carried to America, but in the period from 2001 to 2010 was a real invasion.

Associated Press journalists have access to official documents which give an idea of what kind of damage has been done.

In California, registered at least 19 cases of contamination of crops and the Mediterranean fruit fly. The emergence of the European grozdevoy leaf led to the need spraying and quarantine in the vineyards around the state.

In Florida, there is also a Chilean yellow tea thrips, caterpillars rice pests and odnohozyayny rust fungus (Uromyces transversalis). Overall, from 2003 to 2007 in the state recorded 27 percent growth in new pests and pathogens.

Overall, the number of detections of pests at U.S. ports has decreased from 81,200 in 2002 to less than 58,500 in 2006. In 2007, the farmer finally heard complaints Congress — and the situation began to stabilize.

In 2004, researchers at Cornell University calculated that annual cost of invasive species is $ 120 billion, mainly this burden falls on ordinary consumers, who have to buy food at higher prices, and taxpayers, through which the government takes action. For example, because of the disease of citrus in California, caused by the bacterium Xanthomonas axonopodis, consumers will pay $ 130 million a year more than usual, the experts of the University of California at Davis.

Of course, not only the people suffer.
