Lygus degree-day model for strawberries (Photo illustration by Surendra Dara) Degree-day is the unit of measurement for physiological time for insect maturity. They prefer to feed on the nitrogen-rich growing points and reproductive parts of the plant such as buds, flowers and young seeds. Females of most species use a knife-like ovipositor to insert eggs into plant stems or leaves. Nymphs are bright green and progress through 5 molts (instars) from first hatch to the adult stage. The rate of Lygus bug development is directly related to the amount of heat the bugs are exposed to, so measuring the amount of heat accumulation over time can be used to tell when different developmental stages in the Lygus bug life cycle will occur. Adults overwinter in debris in and around fields. Lygus Bugs Gary L.
