Update on Galling and a New Mite
 
Extension offices around the state have been trying to solve the mystery of plant galling. It has long been a suspicion that a mite was causing this damage, but out of the hundreds of samples collected, there was never evidence to confirm this. Early on, herbicide damage was ruled out and UF has tested multiple samples for a phytoplasma, which could never be isolated.
 
In 2016, landscape professionals in the Jacksonville area reported an increase in damaged plant material and the search continued for answers. Meanwhile, in late 2016, UF/IFAS hired Dr. Adam Dale as the new Landscape & Turf Entomologist. Erin Harlow, UF/IFAS Extension Duval County, expressed concerns about this problem to him and he jumped on board and visited Jacksonville to help collect samples. After seven years of searching, they finally found what we had been looking for - a new mite.

Out of the 27 samples collected, 18 were eriophyid mites, all of which appear to be a new   species with the Aceria genus. Because this is a new mite, it doesn't have a name yet, and there isn't much known about it. Currently, mites have only been collected from loropetalums, although we believe the host list may be larger (in Central Florida, we have  seen ligustrum affected). Management recommendations remain the  same and include cutting and removing foliage and treating with a miticide.
 
Dr. Dale says that he needs more samples and is willing to collect samples from Central Florida as well as North Florida. You can help
by submitting samples, preferably ones that have NOT been treated with an insecticide. Please read below on how to submit samples.

Submitting Samples:
1. Cut symptomatic plant material (remove the leaves, just the galls) and place in a small jar or vial with 70% rubbing alcohol. Make sure the vial or jar is completely closed.
2. Record the location, collector's contact information, pesticides that have been applied, and host plant.
3. Leave the material in the vial for several hours.
4. You can bring samples to the UF/IFAS Extension Orange County at 6021 S. Conway Rd, Orlando FL 32812 or you can mail them to  Nicole Benda at P O Box 110620,  Gainesville, FL 32611.
UF/IFAS Researchers Find 2 Virus-carrying Mosquito Species
 
A UF/IFAS entomologist has found two more non-native mosquito species in Florida that transmit viruses that cause disease in humans and wildlife. That makes nine new mosquito species found in Florida in the past decade.
 
"The presence of any exotic mosquito is important from a nuisance, or biting, standpoint," said Nathan Burkett-Cadena, a UF/IFAS assistant professor of entomology at the UF/IFAS Florida Medical Entomology Laboratory in Vero Beach, Florida. "However, these two species are known to transmit pathogens that affect human and animal health."
 
Burkett-Cadena found the mosquito species Aedeomyia squamipennis and Culex panocossa in Florida City and Homestead, both in south Miami-Dade County. He and Erik Blosser, a post-doctoral researcher at the FMEL, were visiting South Florida to collect a native mosquito species, Culex cedecei, to investigate its biology and ecology, when they noticed the two non-native species.
 
They took samples from several environments including forests, farms, roadside ditches and even populated areas using carbon dioxide-baited light traps and vacuums to collect adults and buckets to collect larvae.
 
Everglades virus, a type of encephalitis virus, is found in South Florida, and Culex panocossa is known to transmit encephalitis viruses. Although the new species were found in South Florida, they will likely spread to other areas of Florida and perhaps neighboring states because of widespread, suitable larval habitat, particularly water lettuce.
 
There is no vaccine or specific treatment for Everglades virus, so preventing mosquito bites is the best protection against infection. While it's not mosquito season in Florida, your best protection against getting bitten by any of these mosquitoes is to wear protective clothing and use repellents, preferably ones that have DEET.

Mosquito Control Licensing
 
If you are considering adding mosquito control as part of your pest control services, here is a reminder from the Florida Department of Agriculture and Consumer Services.
 
Pest Control companies operating in the categories of either General Household Pest (GHP) or Lawn and Ornamental (L&O) may perform mosquito control when the applications are made as a part of the normal pest control business practice. Whether the homeowner or the private homeowner association purchases this pest control service, if it is mosquito control in, on or under a structure, lawn, or ornamental then the Pest Control Operator's certificate will suffice. Area-wide mosquito control such as truck ULV (ultra-low volume) and thermal fogging, as well as larviciding, done within and for a private community is also allowed under the GHP and L&O categories.
 
Pest Control companies contracted to perform mosquito control activities for a government agency or mosquito control district must have a Public Health (PH) license or be operating under the direct supervision of a PH license holder.
