Component descriptions
These summaries translate the attached project descriptions into a linked web of functions, handoffs, and field outcomes.
Project ARTEMIS overview
UMass Amherst / NEWVEC lead hub
ARTEMIS is organized as a translational host-targeted pipeline: screen candidates, test deer interventions at C-VERS, test rodent interventions through mouse bait studies, deploy optimized formulations through field platforms, and assemble effective components into future integrated tick management.
- Backronym: Area-wide Reduction of Ticks through Ecological Management and Integrated Strategies.
- Primary field platforms: C-VERS, Project Chappy / Martha's Vineyard, and Project ITCH residential properties.
- Decision focus: measurable reductions in tick survival, feeding, fecundity, pathogen acquisition, or human-risk indicators.
Acaricide discovery and slow-release oral formulation
Dr. S. Thai Thayumanavan / UMass Center for Bioactive Delivery
This workstream develops slow-releasing oral formulations that can keep active anti-parasitic compounds available long enough to affect feeding ticks while clearing from deer on a defined safety timeline.
- Target profile: activity for roughly 8-10 weeks after administration and clearance by week 20.
- Primary chemistry space: oxazolines, macrocyclic lactones, and phenolic candidates, with attention to hydrophobicity and size.
- Delivery platform: alginate hydrogels combined with tunable PEG-PLGA encapsulation.
Delivery chemistry: prodrugs and biopolymer nanoemulsions
Dr. Vincent Rotello / UMass Department of Chemistry
This component addresses practical field-delivery problems for wildlife acaricides: ingestion, oral uptake efficiency, and duration of activity.
- Strategy 1: synthesize prodrug analogs of fluralaner and lotilaner using fatty or hydrophobic modifiers to improve uptake and retention before conversion back to active drug.
- Strategy 2: use gelatin-and-oil biopolymer nanoemulsions to encapsulate drugs, improve oral uptake, and enable feedstock or vegetation coating.
- Testing path: in vitro screening followed by in vivo mouse models for pharmacokinetics, biodistribution, toxicity, and biocompatibility.
Anti-tick vaccine antigen discovery and oral platforms
Dr. Paulo H. Verardi / University of Connecticut
The vaccine platform identifies antigens from tick transcriptomic data, builds bait-compatible oral vaccine systems, and hands lead candidates to ARTEMIS collaborators for formulation and field-compatible delivery.
- Aim 1: transcriptomic sequencing across feeding stages of I. scapularis and A. americanum to identify candidate antigens.
- Aim 2: recombinant vaccinia and engineered probiotic oral vaccine platforms.
- Aim 3 handoff: lead candidates move into bait formulation for deer and reservoir rodent populations.
White-tailed deer rumen physiology and protective encapsulation
Dr. Todd Callaway / University of Georgia
Oral delivery to deer must survive the rumen. This project tests whether acaricides and vaccine platforms are degraded, transformed, bound, or sequestered before reaching the lower gastrointestinal tract.
- Initial surrogate model: goat ruminal fluid in batch culture and continuous-flow fermenter systems.
- Target-species check: white-tailed deer rumen fluid from hunter-harvested animals where feasible.
- Protection strategies: pH-triggered coatings, lipid nanoparticles, polymer microspheres, and plant-based delivery vectors.
C-VERS captive deer testing platform
Cervid-Vector Ecology Research Station / NEWVEC + MassWildlife
C-VERS provides the controlled deer-testing step between laboratory discovery and field deployment, enabling tick-deer ecological studies and pre-field evaluation of deer-targeted tick intervention agents.
- Near-term use: benchmark fluralaner and another active ingredient in captive deer.
- Core endpoints: tick feeding, tick burden, PK/PD, seasonal cohort effects, and deer response.
- Role in pipeline: a go/no-go gate before free-ranging deer or community deployment.
Free-ranging deer operations and wildlife management
Dr. Martin Feehan / MassWildlife
This workstream converts deer-targeted products into operational field trials using deer density data, treatment and control sites, capture/collar methods, drone surveys, and tick burden measurement.
- Site logic: use aerial drone deer-density surveys to identify spatially distinct study areas.
- Field methods: capture, GPS collaring, treatment delivery, recapture, tick burden reassessment, and annual infrared drone surveys.
- Downstream use: GPS and habitat analyses inform ITM actions such as targeted habitat modification and deer movement barriers.
Rodent-targeted bait strategy
Dr. Andrew Li / USDA-ARS Beltsville Agricultural Research Center
This component develops medicated rodent baits that target white-footed mice and other small mammals that host immature blacklegged ticks and harbor Borrelia burgdorferi.
- Formulation screen: 15-20 natural and synthetic acaricidal or antimicrobial compounds incorporated into standard mouse bait.
- Laboratory endpoints: bait acceptance, daily intake, mouse serum concentration by GC-MS, Borrelia-killing efficacy, tick attachment, feeding, and mortality.
- Field endpoint: Sherman trapping of mice, shrews, and other small mammals, plus tick examination and questing tick flagging.
- ARTEMIS field fit: candidates can be evaluated through Project ITCH residential sites, providing yard-scale evidence for future ITM.
Project ITCH residential properties
Residential field platform sampled in 2023-2025
Project ITCH gives ARTEMIS a residential testing layer: properties with pre-intervention sampling histories, homeowner permissions, and yard-level tick and pathogen baselines.
- Use in ARTEMIS: evaluate rodent bait boxes in the same environments where residents make tick-bite prevention decisions.
- Outcome focus: yard tick density, pathogen prevalence, rodent uptake, small-mammal tick burdens, and residential-risk indicators.
- Integration role: link rodent-targeted control to deer-targeted work so both can become complementary pieces of future ITM plans.
Project Chappy / Martha's Vineyard field prototype
Community platform for bounded proof-of-concept field work
Project Chappy provides a geographically bounded, community-supported field prototype that ARTEMIS can scale into randomized treatment and control studies across Martha's Vineyard.
- Community assets: Chappaquiddick Island Association and Tick-Free Martha's Vineyard support access, logistics, and homeowner recruitment.
- Use in ARTEMIS: deploy prioritized candidates in treatment and control sites with deer, tick, pathogen, KAB, and residential-risk endpoints.
- Strategic role: bridge from C-VERS and lab studies to larger-area field evaluation.
Yard, public-space, pathogen, and KAB sampling
Patrick Roden-Reynolds + Dr. Tom Mather / field operations
This component measures whether host-targeted interventions change the tick-risk environment encountered by residents and visitors.
- Sampling spaces: yards, trails, conservation areas, and public spaces.
- Entomological outcomes: tick density, infection prevalence, life-stage structure, and encounter indicators.
- Human-facing outcomes: knowledge, attitudes, and behaviors related to ticks and tick-borne diseases.
Field epidemiology and public-health impact measurement
Dr. Sam Telford III / Tufts University
This workstream evaluates intervention impact using seroconversion methods, questionnaires, and contextual ecological measurements that help interpret human-risk signals.
- Human-risk measures: serosurveys and questionnaires to estimate incidence and exposure.
- Alpha-gal context: self-reported case analyses and serologic testing of current and archived samples.
- Ecological interpretation: host bloodmeal identification for ticks, including the contribution of non-deer hosts to Lone Star tick populations.
Future integrated tick management plan
The ARTEMIS web is designed so deer-targeted and rodent-targeted components are not isolated products. They become decision-ready tools that can be combined with field surveillance, community KAB work, and habitat or access strategies in a future ITM plan.
