Summary:
Overall goal: Reduce misuse and overuse of pesticides in homes that are ineffective against the brown dog tick (BDT). We will accomplish these goals through cooperative efforts of the Pest Control Industry (PCI), University and USDA collaborators in the southeastern US. Our research objectives include: 1) determination of BDT resistance to permethrin and fipronil; 2) Development of a discriminating dose bioassay to identify field-failure resistance with minimal on-animal rearing; 3) identify resistance mechanisms used by BDT. Through our extension objectives, we will deliver much-needed PCI management protocols and brochures. Our proposal meets S-RIPM program goals by increasing the supply of IPM knowledge to Southeastern US residents and improves household tick pest management. Our project specifically addresses all three IPM Road Map future directions by: 1) reducing costs for residents through improved tick management, 2) reducing human health risks from ticks and overuse of pesticides in homes, and 3) greatly minimizing environmental effects from treatment. Residential areas account for a considerable portion of the Southern region and direct contact with pesticides occurs in homes far in excess than that in food and fiber, making this project highly relevant to stakeholders. Furthermore, >37% or >43 million US households have dogs. Through our results, PCI personnel will effectively target BDT infestations, thereby reducing pesticides applied in homes and around children.
Objectives: Research Objectives: 1. Presence and level of Rhipicephalus sanguineus resistance to permethrin and fipronil using the FAO Larval Packet Test 2. Develop discriminating dose for permethrin and fipronil resistance in brown dog ticks 3. Determination of resistance mechanisms in pyrethroid-resistant brown dog Ticks Extension Objectives: 1. Disseminate Southeastern brown dog tick acaricide resistance status to stakeholders to prevent unnecessary pesticide applications 2. Develop and distribute Best Management Practices for control of the brown dog tick in residential environments |

Final Report: |
|
Results From two reports submitted by the PI to USDA CRIS report system PROGRESS: 2009/09 TO 2010/08 OUTPUTS: The extension component of this project will be delivered when the research has been advanced further. PARTICIPANTS: Amanda Eiden, Ph.D. student; Dr. Faith Oi, UF; Dr. Phil Kaufman is the project PI and provided oversight for all objectives. Dr. Faith Oi will oversee the implementation of the projects extension components. Amanda Eiden is a graduate student who will generate the research results and assist with the extension deliverables development. TARGET AUDIENCES: Florida's residents, small animal veterinarians, dog kennel operators, and dog shelter operators. Many of the topics of this project are utilized in Dr. Kaufman's Medical and Veterinary Entomology courses taught at the University of Florida. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period. IMPACT: 2009/09 TO 2010/08 None - Extension component will be conducted when sufficient research results are obtained. PROGRESS: 2009/09 TO 2010/08 OUTPUTS: To date, four colonies of brown dog tick have been established. Three of these have been submitted for initial permethrin insecticide screening, with resistance demonstrated in all three strains. PARTICIPANTS: Amanda Eiden, Ph.D. student; Dr. Faith Oi, UF; Dr. Robert Miller, USDA, ARS, KBLIRL Dr. Phil Kaufman is the project PI and provided oversight for all objectives. Dr. Faith Oi provided guidance and training for the graduate student working on the project. Dr. Robert Miller provides guidance on resistance testing and training for the graduate student. Amanda Eiden conducted all laboratory studies. TARGET AUDIENCES: Florida's residents, small animal veterinarians, dog kennel operators, and dog shelter operators. Many of the topics of this project are utilized in Dr. Kaufman's Medical and Veterinary Entomology courses taught at the University of Florida. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period. IMPACT: 2009/09 TO 2010/08 Initial screening of three brown dog tick colonies preliminarily suggests that permethrin resistance is present. |
