Learn how Heliria praealta, a treehopper of the Pacific Northwest, lives on orchard trees and how to manage it.
This practical guide explains how to identify the treehopper, track its seasonal cycle, and apply control tactics in fruit orchards. It focuses on the species found on apples and other site hosts in the Washington and Idaho regions, and it covers life stages from egg to adult, plus real-world observations from field work.
Readers will gain clear, step-by-step information on when eggs hatch, how nymphs feed and develop, and how adults behave on dying limbs. The book also discusses how honeydew attracts ants, the distinctive blossom-like nymph crests, and how this insect overwinters in the egg stage.
