Q-biotype whitefly is in Palm Beach County
Q-Biotype Whitefly threat:
Cindy McKenzie, Ph.D., Entomologist, USDA, ARS, and Lance S. Osborne, Ph.D., University of Florida, IFAS report that unfortunately, we have a developing whitefly issue in Florida. We are having major issues managing 2 biotypes in a number of areas in South Florida. Both biotypes are referred to as Bemisia tabaci. The Q biotype has been detected in a number of landscapes in Palm Beach County.
This is the VERY FIRST TIME it has been found in a landscape or outside a greenhouse or nursery since it was found on an ornamental plant in a greenhouse many years ago (2004-2005). This is extremely troubling considering the issues we have with many of the tools we use to manage whiteflies.

Q-biotype whitefly is already resistant to a number of products commonly used. We are concerned that insecticide overuse may already be leading to B-biotype resistance

Now more than ever, you will need to use and maintain the viability of effective insecticide tools.
