Significance of the work: Ticks, especially lone star ticks, are a rapidly expanding problem in the Northeast. This project focused in part on lone star ticks as well as deer ticks, using field research rather than laboratory research. This grant helped us to develop standardized research on the field efficacy of “organic” tick control products, some of which have little information on their labels. By gathering data from workshop participants, we are both educating about ticks and their ecology for better control but we also were able to gather information from local practitioners regarding what cultural controls or products they are using, What was learned or accomplished: Three workshops were given, servicing over 140 members of the industry and other entities and were so popular that we ran out of room and already have over thirty participants scheduled for another workshop to be run on April 6, 2017. We have had a request to replicate the workshops in Westchester County. There was overwhelming interest in the use of GoogleEarth Pro as a planning tool for treatment. We determined the most common products being used in our cross section of participants and are in the process of testing these on a local basis to provide replicated research for creating and enhancing best management practices for tick control particularly with respect to “green products”. Research is still on-going but so far results have indicated the following: Greatest mortality was obtained using Mavrik Perimeter with 97.5% mortality 10 DAT compared to 31.5% reference mortality for lone star tick adults and 100% mortality 16 DAT compared to 35% reference mortality for lone star nymphs. The next best performance was the Cedar Safe product (with 85% cedar oil AI) which produced 47% mortality at 10 DAT compared to reference mortality of 31.5% for lone star tick adults but only 37% mortality at 16 DAT compared to 35% reference mortality for lone star nymphs. These results again point to the utility of hybrid control programs using both “green” products and synthetic products, green closer to points of human contact and synthetic as a perimeter treatment.
