Description

The Bumblebee Y maze, developed by Johannes Spaethe and colleagues in 2003, was designed to quantitatively investigate the link between eye optical quality and target detection ability in bumblebees (Bombus terrestris) across various sizes within the same species. The study demonstrated that larger bumblebees outperformed their smaller counterparts due to superior optical configurations, including larger facets and smaller interommatidial angles.

In the experiment, bumblebee colonies were connected to a flight cage using a Plexiglas tube, with shutters between the nest and the arena to control worker access.

The Y-maze consists of an entrance chamber and two tunnels extending from a central decision chamber, forming a Y shape.

Mazeengineers provides the Bumblebee Y maze, with options for custom coloring and other customizations upon request.

Introduction

The Honeybee Y-maze apparatus is designed to study inferential reasoning and memory retention in honeybees. Adapted from the traditional rodent Y-maze, this setup allows for the use of various visual stimuli as reinforcement.

Honeybees possess advanced sensory capacities and motor skills, enabling them to perceive their environment in diverse colors, shapes, and patterns. These sensory abilities significantly influence behaviors such as foraging, playing a crucial role in their survival. The Honeybee Y-maze offers a platform to explore these capabilities and examine related behaviors using a straightforward two-choice paradigm with different visual cues. Furthermore, honeybees exhibit sophisticated memory and the flexibility to adjust their preferences based on cues like temporal context (Zhang et al., 2006). This apparatus can be utilized to study learning behaviors and memory through various experimental protocols, such as reversal learning and discrimination learning.

The Honeybee Y-maze features a conventional Y design with a starting area that splits into two choice arms. An aperture in the start area allows the honeybee to enter the maze. The choice arms are equipped with placements for visual cues and a micropipette in the center of the wall to hold food rewards. Other tools used for evaluating cognitive and learning behaviors in honeybees include the Bumblebee Y-maze, the Bee Reward Expectations Apparatus, and the Bee Radial Arm.

Apparatus and Equipment

The Honeybee Y-maze apparatus is constructed from acrylic and features a Y shape, consisting of a start area and two choice arms. The apparatus includes a UV-transparent Plexiglas ceiling. The start area measures 16.5 x 26.5 cm and is equipped with a sliding door. Opposite this sliding door is an entrance hole with a 5 cm diameter. This entrance hole leads to a decision area, which branches into two choice arms, each measuring 40 x 20 cm. The back wall of each arm, measuring 20 x 20 cm, is designed to hold a visual stimulus and includes a 6 mm micropipette at its center for dispensing food reinforcements.

Training Protocol

Clean the device before and after usage. Observation and recording of the movements of the subjects can be done using a tracking device such as theĀ Noldus EthoVision XT.

Train the subjects during the light cycle. Use fresh visual stimuli in all test performances to prevent influence by odor.

Data Analysis

The following data can be analyzed by using the Y-maze apparatus:

  • Number of times the subject chose each stimulus
  • Number of times the sucrose awarded stimulus was chosen
  • Number of times the unrewarded stimulus was chosen
  • Number correct choices per premise pair
  • Total number of incorrect choices
  • Reward/Penalty ratio
  • Number of touches for each stimulus
  • Number of times a stimulus was chosen first.

A decision is said to have been made when the subject crosses the dotted line.

Strengths and Limitations

Summary

  • The Honeybee Y-maze apparatus is used to study inferential reasoning and memory retention in honeybees.
  • The sliding door allows controlling of entries and exits of the subject to and from the maze.
  • The choice arms are equipped with micropipettes which allow holding of food reinforcements without any spillage.
  • The Honeybee Y-maze can be equipped with a range of removable visual stimuli and can be easily adapted for different investigatory needs.
  • The maze can be effectively used to evaluate choice behaviors, learning and discrimination behaviors, and memory under different task protocols and investigatory aims.
