his pest that was discovered in Florida in August 2005. University of Florida researchers are working on a variety of methods to combat this problem, including development of disease-resistant cultivars, identifying predators that might control the spread of the psyllid, as well as other potential avenues for control.
The same solutions that work for the commercial industry will also likely be available to dooryard producers.
Another pest that has generated calls to the extension office recently is the Cuban tree frog. Although accidently introduced in South Florida in the 1920s, the Cuban tree frog has spread into the North Central portion of the state only in recent years. This frog is a pest in Florida because it eats at least five species of native frogs, and its tadpoles compete with native populations for food and space. The tree frog hangs out under the eaves of houses where it catches insects and is a problem for homeowners because it defecates on walls and windows, leaving ugly stains. Occasionally, the frog finds its way into houses where it hangs out near toilets and may clog sink drains.
Cuban tree frogs are difficult to identify because they come in a variety of colors, including white, gray, green and brown, and they may have dark streaks or splotches on their backs while others are a solid color. Like all tree frogs, they have round pads on the ends of their toes that enable them to climb trees. This is very different from aquatic frogs that have webbing between the toes. In the case of the Cuban tree frog, the toe pads are unusually large, distinguishing them from other tree frogs.
Because this species is harmful to the environment, it is illegal to capture and release them into the wild. Those discovering Cuban tree frogs are encouraged to euthanize them in a humane manner. Capture the frog in a plastic bag to avoid contact with its skin secretion — it can irritate the nose and eyes and may trigger attacks in those who suffer from asthma. Next, apply benzocaine (20 percent) to the back or belly of the frog. Products containing 20-percent benzocaine are available at your local drugstore (first-aid or burn sprays and toothache gels or liquids). After applying the benzocaine, the frog will quickly become unconscious. Next, seal the plastic bag and put it in the freezer overnight, which will humanely kill the frog. Dispose of the bag in the trash the next day.
Because of Florida's favorable climate and the extensive travel that takes place within the state, the state is subject to invasive pests. It is important for everyone to do their part to help minimize the effects of nuisance invaders.
