MIN/MAX THERMOMETER
 
   A useful tool to help keep track of degree days which are an important part of biological monitoring, especially for insect and mite populations. Insects are cold blooded, their growth responds to and is determined by climatic conditions such as temperature, photoperiod, and humidity. The lower threshold for most insects is averaged at:
50 degrees Average Daily Temp- Lower Development Threshold = degree days
(80+40F)-50F=10 degree days
      2

Degree days are accumulative throughout the year adding one day total to the next, etc.
