Psyllid Identification Key to Area-wide Control of Citrus Greening Spread (Nov 3, 2010)
USDA. Agricultural Research Service.
With help from colleagues in Texas and Florida, U.S.. Department of Agriculture scientist has identified at least six psyllid species present in south Texas citrus groves. Some are native to the Rio Grande Valley, but others, like the Asian citrus psyllid, are not. The scientists are examining the life cycles of the six species to determine which of them can spread Huanglongbing (HLB). This will help scientists target certain species for control measures. The disease was first detected in Florida in 2005 and now poses a significant threat to the entire U.S. citrus industry. For more information on the research, see the article Citrus Greening? Not If These Scientists Can Help It!, published in the Nov/Dec 2010 issue of Agricultural Research magazine.
