A good approximation of the degree-days accumulated for a pest can be calculated by knowing: The identity and life cycle of the pest and the crop. When to start accumulating degree-days for a pest. The minimum and maximum temperatures at which the pest will develop. The highest and lowest temperatures in the field or orchard during pest development.
Scouting efficiency can be increased by knowing the number of degree days required for a pest to reach a destructive growth stage. Alfalfa weevil is a good example of this use of GDD. Table 2 lists the degree day requirements for this economic pest of alfalfa.igure 1. When an organism's growth rate is predominantly under temperature control its rate of development can be characterized using a system called growing-degree days (GDD) or heat units (HU). This GDD concept assumes that: 1  There is a base temperature below which the organism does not grow or grows very slowly.
