University of Kentucky Pest Control Short Course
In pest control, the "rubber meets the road" in the trenches. Effective educational conferences transport attendees from their hard-back chairs-to crawlspaces, attics, kitchens, bed rooms, yards, and other places where pests dwell. Make the topics relevant; Keep it hands on; Give me tips and ideas I can take home and put into practice... If these feelings hit home, the 2014 University of Kentucky Pest Control Short Course is for you.

Tailored to industry professionals, the Short Course is packed with helpful info for owners, managers and technicians alike. This year's topics include a half-day business roundtable, a food service house of learning, the truth about bees and pesticides, trouble-shooting German, American and Oriental cockroach infestations, new bed bug information (of course), how pests navigate through buildings, the secret life of termites, insecticides lessons of a lifetime, dealing with annoyed (and annoying) customers, and "Tips from the trenches" for managing ants, flies, stink bugs, rodents, nuisance wildlife and other pests - dozens of useful subjects, a terrific trade show, and the best speakers in the business. As always, if you attend and are not satisfied with the learning experience, we'll gladly refund your registration fee. Check out the 2014 program agenda and registration form to see what this conference is all about...it's all about YOU!

2014 West Nile Virus Update
West Nile virus is an arthropod-borne virus (arbovirus) most commonly transmitted by the bite of an infected mosquito. Since the first detection of West Nile virus in North American in 1999, several mosquitoes have been found to harbor the virus, including Aedes, Anopheles, Culex, and several other mosquito genera. West Nile virus can cause febrile illness, encephalitis or meningitis, however, 70-80 percent of people infected with West Nile virus are asymptomatic.

According to the latest update by the Centers for Disease Control and Prevention (CDC), 40 states and the District of Columbia have reported cases of West Nile in at least one resident with a total of 1,177 people diagnosed with West Nile virus infections in 2014, a slight uptick from 2013. However, based on the high percentage of asymptomatic infections, the true number of West Nile cases is likely much higher. All told, there have been 43 fatalities attributed to West Nile virus in 2014. California (374), Texas (155), and Louisiana (102) have experienced the highest number of infections, cumulatively accounting for over fifty percent of the nationwide total. Peak season is from June to September, correlated with mosquito activity.

Modeling the Spread of Invasive Termites 


The Invasive species regularly arrive in the United States, but what happens next is less predictable. Some species die out before they are ever noticed while others are capable of becoming established and even thriving in their new environment. Two highly destructive and economically important invasive termite species, the Formosan subterranean termite (Coptotermes formosanus) and the Asian subterranean termite (Coptotermes gestroi), were recently analyzed for their likelihood of expansion into new territory. Both species are native to Asia but have been able to exploit several disparate regions after accidental introductions. Currently, the Formosan termite is restricted to southern and coastal regions of the United States, especially Hawaii and the southeast, while the Asian subterranean termite is not yet established in the U.S.

Francesco Tonini of the University of Florida led an international team of scientists to model future distribution of these species based on current climatic conditions and anticipated climate changes by using current occurrence records. Predicted expansion and population densities for both species was closely linked to urban development, while a warming climate indicates an increased likelihood of expansion into new areas compared to current conditions. This research was published in a paper titled, "Predicting the Geographical Distribution of Two Invasive Termite Species from Occurrence Data" and published in a recent volume of Environmental Entomology.

Rutgers Researchers Publish Important Study on Efficacy of "Minimum-Risk" Products for Bed Bug Control 
NPMA has been extremely concerned about the avalanche of minimum-risk or 25b pesticides marketed for bed bug control that have entered the market the last few years and the effectiveness of such products. These pesticides are exempt from the U.S. Environmental Protection Agency's normal registration requirements, largely because they are oil or plant based and deemed to pose no risk to human health or the environment and are seemingly free to make claims about the products' efficacy and toxicity that conventional pesticides may not make.

Newly published research by Rutgers University's Dr. Changlu Wang, Richard Cooper and Narinderpal Singh evaluates the efficacy of 11 minimum risk products marketed for bed bug control as well as two widely used synthetic pesticides including a relatively new combination neonicotinoid/synthetic pyrethroid product. While the results of the study were wide ranging, they do justify NPMA's concern about the EPA's lack of scrutiny of minimum risk products and raise significant public policy questions as we move in to the second half of the second decade of the bed bug resurgence in the United States. The research also underscores the value of the new combination products in controlling bed bug infestations and the importance of protecting those and other structural uses from local pesticide bans.
