Research Project: Development and Testing of Remote Activated Ultra-quiet Field sprayer for Eradication of Cattle Fever Ticks on Nilgai and White-tailed Deer

Location: Livestock Arthropod Pests Research

Project Number: 3094-32000-039-90-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jul 1, 2018
End Date: Jun 30, 2020

The objectives of this cooperative research are to: 1) Conduct large-scale deployment of sprayers and determine efficacy of entomopathogenic nematodes to eradicate cattle fever ticks on nilgai, 2) design and test remotely activated sprayers deployed on white-tailed deer (WTD).

Research with sprayers will take place at a private ranch in Willacy County with free-ranging populations of nilgai and WTD. Native Steinernema riobrave entomopathogenic nematodes will be used to treat wildlife for cattle fever ticks by remotely activated, motion detecting, sprayers. Sprayers deployed at the ranch will be maintained by 3 crews of field technicians. Sprayers will be set up at fence crossings, common latrines and feeders (WTD). Counts of ticks on hunter-harvested wildlife (>120 nilgai and 100 WTD) will be conducted by Cattle Fever Tick Eradication Program personnel and provided to ARS to assess efficacy of the program during the year-long program.
