Clastoptera brunnea

Systematic position: Clastoptera brunnea is a member of the order Hemiptera and the family Clastopteridae. Commonly known as a type of spittlebug, this insect is recognized for its specialized feeding habits and its ability to thrive on specific host plants across North America.

Host plants: This pest primarily targets species within the Ericaceae family. It is frequently observed on blueberry and cranberry crops, where it can cause significant damage if populations remain uncontrolled during the growing season.

Biology and life cycle: The life cycle involves egg, nymph, and adult stages. Nymphs are distinctively known for producing a frothy, spit-like substance. This protective barrier surrounds the nymph, providing insulation against environmental stressors and predators while allowing the insect to feed undisturbed.

Damage and economic impact: Damage is caused by nymphs extracting sap from young shoots and leaves. Typical symptoms include stunted growth, leaf distortion, and general plant vigor decline. In commercial agriculture, severe infestations lead to substantial losses in berry yield and fruit quality.

Control measures: Management strategies emphasize early detection and chemical or mechanical interventions. Effective control practices include:

• Monitoring for spittle masses in late spring.
• Pruning and removing infested branches.
• Applying systemic or contact insecticides when high population densities are observed.
