US (FL): Potential whitefly outbreak threatens crops

The Q-biotype whitefly, a significant tropical and subtropical pest, may threaten Florida crops such as tomatoes, squash, beans, watermelons and many other vegetables and ornamentals if immediate measures are not taken to prevent its spread.



Scientists statewide, including those with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), are working together to control the whitefly which, for the first time, has been found outside greenhouses and nurseries in Florida. Known scientifically as Bemisia tabaci, the Q-biotype or Mediterranean whitefly is a light-colored, flying insect slightly less than 1 millimeter in length.

Researchers with UF/IFAS are working with the U.S. Department of Agriculture, Agricultural Research Service and the Florida Department of Agriculture and Consumer Services to manage the whitefly.

“Unfortunately, we have a developing whitefly issue in Florida,” said Lance Osborne, a faculty member at the UF/IFAS Mid-Florida Research and Education Center in Apopka, Florida. “The situation may be improved with diligent attention to identifying and reporting any outbreaks.”

This marks the first time the Q-biotype of Bemisia tabaci has been found outside a greenhouse or nursery in the United States since it was found on an ornamental plant in a greenhouse in 2004-2005, said Osborne, a UF/IFAS entomology professor.
