Method synopsis

A two-phase field protocol using training baits scented with plant chemicals followed by two-choice tests to assess whether ants form associative memories linking plant odors to carbohydrate rewards. Ants are trained on scented baits for 24 hours, then tested for preference using choice apparatus with matching vs. non-matching scents.

Synthesized from method descriptions across 3 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Are ants botanists? Ant associative learning of plant chemicals mediates foraging for carbohydrates (2020), Ecological Entomology. The protocol was originally introduced by The ability of ants to associatively learn based on olfactory chemical cues produced by plants. (2017). Implementations in other papers (listed below) may differ.

1. Deploy training baits along transects
   Deployed 10-14 artificial training baits along a transect in each site, with baits separated by at least 10 m minimum distance to avoid sampling the same ant colony repeatedly. Baits consisted of 10 mL of 20% forest honey solution by mass in 15 mL plastic centrifuge tubes fitted with cotton wicks.
   Quantities: 200 total baits across 160 separate transect locations, 10 m minimum spacing between baits, 10 mL volume per bait, 20% honey concentration by massDuration: Deployed on one to three separate occasions per siteConditions: Deployed during active ant foraging periods
   Equipment: 15 mL plastic centrifuge tubes, cotton wicks, forest honey, measuring equipment
2. Prepare scented bamboo stakes
   Attached training baits to 10-cm sanded and lacquered bamboo sticks. Rubbed sticks once with fresh leaves from either H. quinquenervis or L. porteri, alternating between species along the transect. Leaves were locally collected from plants that visually appeared undamaged by herbivores.
   Quantities: 10-cm length bamboo sticks, alternating plant species treatment along transectsDuration: Preparation done immediately before bait deploymentConditions: Fresh leaves collected on deployment day
   Equipment: 10-cm bamboo sticks, sandpaper, lacquer, fresh plant leaves
