Dr. Steve Johnson, UF/IFAS Associate Professor of Wildlife Ecology will be the featured speaker on June 6th
June 6th is a great day to learn about all types of invasive species that threaten natural areas in Northwest Florida!
The UF/IFAS Extension Bay County office will have multiple educational exhibits with living samples of species of concern from 9 a.m. – 5 p.m. on Wednesday, June 6th. This is a multi-agency effort to inform citizens about the impact of invasive plants and animals and how they can help reduce introduction and spread. For full details see the Bay_Invasive Workshop Flyer
We are pleased to announce our partners Florida Fish and Wildlife Conservation Commission (FWC) and Science and Discovery Center of Northwest Florida will be on hand to share information about caring for exotic pets and current management plans for invasive species such as Lionfish, Aquatic Weeds, and how to surrender an animal on designated Pet Amnesty Days.
At noon there will be a special guest speaker for a bring your own lunch & learn “Exotic Invaders: Reptiles and Amphibians of Concern in NW FL.” Dr. Steven Johnson, UF/IFAS Associate Professor of Wildlife Ecology, will talk about exotic reptiles and amphibians we should be aware of that may occur in our area.
In the morning, we will be focusing on the invasive air potato vine with the distribution of air potato leaf beetles for biological control. Need air potato leaf beetles to manage the air potato vine on your property? Please register here http://bit.ly/bayairpotato to receive beetles – they will be distributed from 9 a.m. – noon on June 6th.

Air potatoes got you down? Have no fear, for the Air Potato Challenge is coming to Leon County!
Register now to attend the Air Potato Challenge event on May 18, 9 a.m. to 12 p.m. at the FAMU Center for Viticulture and Small Fruit Research (6361 Mahan Drive, Tallahassee, FL) and receive a supply of air potato beetles to use on your property.
After years of testing, air potato beetles became available as a biological control in 2012 to help combat the invasive herbaceous perennial air potato vine (Dioscorea bulbifera). Air potatoes arrived in south Florida from China in the early 1900s and have steadily crept north until they are now invading the Panhandle Region. Fortunately, air potato beetles have dietary requirements that are very specific, relying strictly upon air potatoes to complete their life cycles.
This is why a team of researchers and Extension agents have come together to help spread air potato beetles as a biological control strategy. Many agencies and counties are involved in this effort, including UF/IFAS Extension St. Lucie County, UF/IFAS Indian River Research and Education Center, the Florida Department of Agriculture Division of Plant Industry, the USDA, Florida Fish and Wildlife, UF/IFAS Extension Leon County, and Florida A&M University.
From 9 a.m. to noon on May 18, Florida residents and public land managers are invited to come out to the FAMU Center for Viticulture and Small Fruit Research to get more information about the invasive air potato and its biological controller, the air potato beetle, and receive a supply of beetles to use on their properties.

Bees, butterflies and other insects play important roles as pollinators in our environment. Over 50 major crops in the United States and at least 13 crops in Florida depend on honey bees. Many native plants in natural areas also depend on insect pollinators for reproduction. In Florida, over 300 bee species play a role in pollination!
Many factors affect the health of our pollinators. One of those factors we can easily control in our own landscapes is exposures to pesticides. How are bees and other pollinators exposed to pesticides? Here are some of the major routes:
- Drift of pesticides sprayed in breezy/windy conditions
- The erosion of contaminated topsoil blowing in the wind
- Direct feeding on pollen and nectar of treated plants
- Contact with pesticides that have blown onto plant surfaces
- Contact with water transpired by leaves of treated plants
- Pesticides that move down through the soil to affect ground dwelling bees and other insects
Did you know that bees become statically charged when they fly causing particles in the air to attract to them?
What are some ways that we can reduce the risk of exposure to pollinators in our landscapes?
- Use integrated pest management principles to reduce the incidence of pests and their impacts.
- Avoid treating areas containing flowering weeds/plants with insecticides. If you must treat your lawn with an insecticide, and it contains flowering weeds, mow the lawn and remove the flowers just before applying the insecticide.
- If you must apply a systemic insecticide to your lawn, leave a buffer strip of several feet between the lawn and the border of landscape beds with flowering plants. This will prevent the flowering plants from up taking the systemic product.
- Postpone any insecticide treatment until after all blooms have fallen from flowering ornamentals. Never apply an insecticide to blooms or flowering plants.
- Avoid the use of neonicotinoids as this class of insecticides can be more toxic to bees than other classes of insecticides. There are many effective alternatives.
Bee friendly to our pollinators!

Sometimes you don’t realize a tree is dying until it is dead. A few weeks ago, we got a call from a client who said he had insects killing his trees. Before having someone drive out to the property, our Master Gardener volunteer recommended that the client bring in some of the insects for us to take a look. It turned out the insects invading his pine tree were a type of longhorned beetle, but more specimens were required for identification. A site visit soon ensued.
There were a number of pine trees on the property, however only one was infested with the insects in question. Upon closer investigation, we noticed a number of different sized holes in the tree. The larger holes are nearly the size of a dime.

It turns out the insects making the larger holes are a type of longhorned beetle known as an arrowhead borer (Xylotrechus sagittatus). The borers are brown to black in color with a reddish hue. They are moderately hairy and some specimens contain arrowhead markings pointing toward their heads. Adults feed on the bark of damaged or fire-killed pines. The adults are attracted to lights and may be mistaken for crickets because they run very fast. Eggs are laid in bark and larvae feed on sapwood, then tunnel deeper, often tunneling within a single annual ring. The borers pupate inside the tree and the newly emerged adults chew their way out.

Given the fact that arrowhead borers are attracted to dead or dying trees, the killer of this particular tree is still in question. The smaller holes in the bark picture above were created by a much smaller beetle, but we were unable to get a specimen. We did see a couple of these beetles running around when we dug deeper into the bark. The small beetles that we saw closely resembled a type of Ips engraver beetle. Beetles in this genus have been known to kill trees, but most likely they weren’t the culprits either. Based on the overall appearance of the tree and the fact that other trees in the area were not infested with beetles, it is believed the tree was killed by other means. The tree was likely struck by lightening or suffered from poor genetics because it did not have a good form for a pine tree.
If you have a questionable looking tree on your property or if you have insects you would like identified, please feel free to stop by your local Extension Office and ask a Master Gardener!
