Target Audiences for Animal Agriculture: Oklahoma Cattlemen's Association Target Audiences for IPM Education for Pesticide Educators: Oklahoma Pest Management Association, Oklahoma Extension Educators, Cherokee Nation, Pest Management Professionals, EPA Changes/Problems:The new horn fly sampling model took longer to develop due to personnel challenges with an initial graduate student leaving the program which delayed the project by 1.5 years. This delay did not allow the model to be converted into a smartphone app utilizing the new binomial sequential sampling model for horn flies in cattle. However, once another graduate student was assigned to this project it lead to a highly predictive model for horn flies that was more accurate and less time consuming for stakeholders. This new model for treatment for horn flies in cattle takes into account if a herd is a purebred angus herd or a mixed breed herd that incorporates angus genetics due to the marketability of this breed. What opportunities for training and professional development has the project provided?The project provided over 56different Extension organized training sessions for both Extension professionals and stakeholders. Additional, training was provided specifially for the new smartphone app for the Sorghum Aphid to over 105 Certified Crop Advisors (CCA). Training of Extension animal science specialists was provided through seminars and graduate student presentations for the new horn fly sampling model. How have the results been disseminated to communities of interest?All results from this project were disseminated through common commodity groups in Oklahoma including the Oklahoma Wheat Commission, Oklahoma Wheat Growers, Oklahoma Soybean Board, Peanut Commission, and the Oklahoma Cattleman's Association. Popular press including trade magazines, YouTube channels, and local media stations on all activities associated with IPM Oklahoma. What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts
What was accomplished under these goals?
ACCOMPLISHMENT: A smartphone app was developed using funds from this project for the Sorghum Aphid ACCOMPLISHMENT: Several economically important pests were monitored throughout the reporting period including sorghum aphids, wheat curl mites, several lepidopteran pests, and occasional pests of wheat / sorghum.Timely newsletters were developed for each major pest infesting wheat and sorghum. ACCOMPLISHMENT: Demonstrations were setup through out the state that showed stakeholders how to monitor for beneficail insects which were incorporated into the new smartphone app. ACCOMPLISHMENT: A new sampling model was established that cut the time for treatment decisions by half through an easier threshold for cattle producers to visualize horn fly populations that met treatment threshold instead of requiring stakeholders to count flies on individual animals. This new tool established a binomial sequential sampling protocol that established a treatment threshold of 350 for black hided animals and 400 for light hided animals which reflects breed preference of the horn fly. ACCOMPLISHMENT: Extension brochures are currently being developed from the new sampling model for horn flies. ACCOMPLISHMENT: Measures of reproduction performance in cattle that were monitored with the new sampling model did not demonstrate differences in relation to different fly populations on the animals. ACCOMPLISHMENT: The new monitoring tool was completed in March 2025 soadoption rates were not measured but stakeholders were sampled to determine which threshold was visually easier to determine when a herd needed to be treated based on the new horn fly sampling model.

Target Audience:Oklahoma Cattleman's Association, Oklahoma Wheat Growers Association, Oklahoma Wheat Commission, Oklahoma Oilseed Commission, Great Plains Canola Association, Oklahoma Cotton Council, National Sorghum Growers, Oklahoma Certified Crop Advisors, Oklahoma Aerial Applicators Association, Oklahoma Grain and Feed Association. Target Audiences for Animal Agriculture: Oklahoma Cattlemen's Association Target Audiences for IPM Education for Pesticide Educators: Oklahoma Pest Management Association, Oklahoma Extension Educators, Cherokee Nation, Pest Management Professionals, EPA Changes/Problems:The initial IPM coordiantor retired however a new IPM Coordinator began in January of 2024. This led to a gap in dissminating information related to the project. This transition made it difficult to complete certain goals. What opportunities for training and professional development has the project provided? In-service trainings for Extension personnelwere held which demonstrated the beta version of the aphid app. Certified Crop Advisors were given training in the beta version of the app. The new sampling protocol for horn flies was introduced to animal science professionals both at scientific and cattleman's meetings throughout Oklahoma. How have the results been disseminated to communities of interest? The aphid app was introduced to wheat and sorghum stakeholders, including crop advisors. Information on how the app takes into account the level of naturally beneficial insects present to adjust treatment thresholds was demonstrated to wheat and sorghum growers. Cattlemen groups were introduced to the new sampling protocol for horn flies that will eventually be developed into a smartphone app for this clientele in the next EIP funding cycle. What do you plan to do during the next reporting period to accomplish the goals? Finalize the Aphid smartphone app for stakeholder use. Finalize and publish the new protocol for horn fly sampling in cattle.
Impacts
What was accomplished under these goals?
Smartphone apps were being developed by the app developer group with OSU, with completion projected to occur in December of 2024 for both wheat and sorghum aphids. All sampling and validation of the app will occur in the next EIP funding cycle with a new IPM Coordinator. Validation of the binomial sequential sampling plan for horn flies in beef cattle was completed by the student and will serve as the basis for future sampling protocols associated with an app in the future.
