Paperback. Condizione: New. Print on Demand. This book is about Heliria praealta, a treehopper species commonly found in apple trees and other fruit plants in the Pacific Northwest of the United States. Discovered first in 1914, the author details studies carried out between 1929 to 1934 in an attempt to ascertain the importance and impact of Heliria praealta on apple orchards. Spanning five years, the author examines where Heliria praealta is found, how these pests feed, their mating behaviors, and the best methods of control. With thoroughness, the author explores the seasonal timeline of Heliria praealta, from egg to adult, to predict its activity and best combat its presence. The knowledge gained from this exploration of Heliria praealta identifies the treehopper as an often secondary but potentially dangerous pest in orchards. This book is a foundational text for entomologists, orchard owners, and farmers, providing a thorough understanding of Heliria praealta and ways to manage its impact on fruit production.
