Description

Controlled heating and cooling assays to determine critical thermal maximum (CTmax) and minimum (CTmin) temperatures of bumblebees under field conditions. Includes environmental optimization trials to determine most stable conditions.

Typical Equipment

  • Styrofoam boxes
  • aluminum block
  • glass vials
  • falcon tubes
  • thermal couples
  • Pico Technology Software
  • portable power bank
  • salt
  • ice
  • shade canopy

Output Measurements

  • CTmax temperature
  • CTmin temperature
  • time to chill-induced coma
  • recovery time
  • intertegular distance
