INSECTS of...Hardwood Branch and Stem

Common Name:	CICADAS An adult CICADA.
Species	Diceroprocta spp. Tibicen spp.
Common Hosts:	Hardwoods Softwoods
Description	Adult -- approximately 15-35 mm long; prominent eyes; brownish-green head and body; stout body; transparent wings with conspicuous veins. Loud trilling noisemakers.
Importance	Severe damage by egg-laying habit of the adult females may result in branch dieback or altered growth form. Nymphs feed by inserting sucking mouth parts into roots in the soil.
Signs of Infestation	Foliage discoloration and/or wilt. Branch wounds consisting of a slit surrounded by torn wood fibers through the bark; caused by females laying eggs in the branch. After hatching, nymphs drop to the ground. Nymphal skins (light brown, split insect cases with prominent legs) attached to tree trunks or lower branches. Adults emerge from the skins. Male adults call from tree crowns to attract females.
Control	Identify and remove highly susceptible trees. Minimize injuries to trees; promote health. Use an approved insecticide to minimize possibility of infestation.
