A new invasive species has begun flying around and pestering fruit growers in Oklahoma.
A Tulsa County grower recently captured a suspicious looking fly. The grower called the Tulsa County Extension Office who shipped the insect to Oklahoma State University’s Department of Entomology and Plant Pathology for identification. The OSU Plant Disease and Insect Diagnostics Laboratory confirmed the capture as the spotted wing drosophila.
The rather small vinegar fly or fruit fly attacks ripening or ripe soft fruits including blackberry, blueberry, boysenberry, grapes, raspberry, strawberry and tree fruits (peach, apricot, cherry, mulberry, nectarine, persimmon and plum). The SWD also has been known to attack melons and tomatoes.
“Spotted wing drosophila was first detected in the United States in California in 2008, where it eventually spread north to British Columbia and south all the way to Florida,” said Phil Mulder, EPP department head. “As recently as 2012, SWD was confirmed in Arkansas, Colorado, Idaho, Illinois, Indiana, Iowa, Kentucky and Minnesota.”
Based on its rapid movement across the country and the fact these flies cannot fly very far, it is thought to be spread by humans transporting infested fruits.
“What makes SWD potentially more economically important than other fruit flies is its ability to cut into intact fruit, using their serrated ovipositor to inject eggs under the skin,” said Eric Rebek, OSU Extension entomologist. “This allows the subsequent larval stage to be present during ripening and can lead to detection in ripe fruit after harvest.”
Oklahoma fruit growers should be mindful of three important components in effective management of SWD. The first step is monitoring, which can be easily conducted through a simple trap baited with pure apple cider vinegar.
“Identification is the second component, which can be difficult for the untrained eye. These tiny flies are only 2–3 millimeters in length,” Mulder said. “Male SWD possess a shadowy spot near the apex of each forewing, while females lack these spots.”
The females have a distinct ovipositor with two rows of serrations longer and darker than other vinegar flies. For help with identification, samples can be submitted to the OSU Plant Disease and Insect Diagnostics Laboratory (http://entoplp.okstate.edu/pddl/pdidl).
“Once SWD have been detected, management activities should begin immediately,” said Jackie Lee, pesticide coordinator for the Division of Agricultural Sciences and Natural Resources at OSU. “From a cultural standpoint, growers can minimize the population buildup by harvesting on time and removing overripe fruit and wild hosts such as wild grape, raspberry and blackberry from nearby locations.”
If an insecticide is applied for control, selection should be based on several factors including harvest date, re-entry restrictions, impact on existing Integrated Pest Management (IPM) programs, beneficial insects and environmental conditions.
Spinosyns (Delegate®, Success® Entrust®) and organic pyrethrum (Pyganic®) insecticides have shown activity on this pest, but so have some of the carbamates (Sevin® or Lannate®), organophosphates (Imidan® or Malathion®) and pyrethroids (Asana®, Brigade®, Danitol®, Mustang-Max®). Azadirachtin (Aza-Direct®) also has proven to be effective.
“Irrespective of the choice of insecticide, it is imperative growers strictly follow restrictions regarding harvest and re-entry,” Lee said. “In addition, it is also important to rotate between the various chemical classes to avoid development of insecticide resistance.”

Personal genetic tests face sharper scrutiny after 23andMe

Guthrie-Edmond airport looks to upgrade
The Guthrie-Edmond Regional Airport board was told Tuesday by officials from the Oklahoma Aeronautics Commission that GERA is in good shape but work needs to continue to help maximize everything the airport has to offer.
The board was given a presentation by OAC director Vic Bird and Dale Williams, OAC planning division manager about the state of the aviation industry in Oklahoma and how airports the size of GERA are faring.
Cold impacts Edmond businesses, city services
Roger Seaton is operating manager of Edmond Air Conditioning, Heating and Plumbing, 3104 South Kelly Ave., owned by the Seaton family since 1970.
On Tuesday, for the first time in days, the temperature in the Edmond area rose above 32 degrees. At 2:53 p.m. Tuesday, the temperature was 41 degrees at the Guthrie-Edmond Regional Airport, surpassing the predicted high of 34, according to the National Weather Service.
Seaton’s business offers plumbing services including water line work and repairs to faucets in the kitchen and bathroom. When it comes to plumbing calls, pipes that burst are a priority, Seaton said. It takes a while for pipes to freeze, he said, and residents began calling by Friday. Calls during the cold spell were both about frozen pipes and pipes that had burst.
If you have no water coming out of a faucet, shut off the water upstream and open cabinet doors to get warmer air circulating around pipes, Seaton said.
City alerts public to repeat utility scam
City administrators and public safety officials are jointly warning residents of a scam that has surfaced once again in our area.
Edmond Police Department spokeswoman Jenny Monroe said a few months ago OG&E warned customers of a phone scam in which a customer is called by a person falsely representing themselves as an OG&E employee.
Monroe said the caller says if the customer doesn’t make a payment on their delinquent account in the next 45 minutes to an hour their utility services will be suspended. Monroe said the caller requests credit card information or that they purchase a money card and provide that account information.

Federal energy efficiency tax credits ending in 2013
If you are planning to do some home improvements to make your home more energy efficient, now is the time to take action. Multiple federal energy efficiency tax credits are set to expire permanently at the end of the year.
Oklahomans have until Dec. 31 to take advantage of a cumulative maximum of $500 in credits for energy-related improvements completed in 2011, 2012 and 2013. The credits are a cumulative maximum of $1,500 for improvements done in 2009 and 2010.
The tax credits are for energy improvements done to existing homes owned by you, and used as your principal residence, said Scott Frazier, Oklahoma State University Cooperative Extension energy management engineer. New construction and rentals are not eligible for these federal tax credits.
