Arizona has 3 Termites of economic concern: - correct answer✔✔Subterranean= 100,000+
termites in a colony
Drywood= 100s-1000s of termites
Dampwood= 100s of termites
Wood is made of 3 dominant ingredients: - correct answer✔✔Cellulose (preferred)
, Lignin (avoided) removed when paper is made

Alates are easy prey
Less than 3% survive
Wind has strong influence on direction and distance
Workers: feed all members of colony and cause damage
Nymphs - correct answer✔✔future reproductive
