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
