GAINESVILLE, Fla. — People in Palm Beach County can help manage a potential outbreak of the Q-biotype whitefly through early detection and identification of the insect, a University of Florida Institute of Food and Agricultural Sciences researcher says.
This 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. Known scientifically as Bemisia tabaci, the Q-biotype is a light-colored, flying insect slightly less than 1 millimeter in length. Thus far, the Q-biotype whitefly has been reported in all four quadrants of Palm Beach County – north, east, south and west – said Lance Osborne, a UF/IFAS entomology professor.
To find and detect this whitely, residents should first look at hibiscus plants because those are host plants to which this whitefly species will likely gravitate. They should also take a look at their poinsettia plants, Osborne said. There are two types of this whitefly species: Q-biotype and B-biotype, and they look virtually the same, so it’s critical to get a genetic analysis to determine if you have the Q-biotype whitefly.
