Paperback. Etat : New. Print on Demand. This book explores the travels of Albert Koebele, a US Department of Agriculture agent, who was tasked with traveling to Australia to study the natural enemies of the Fluted Scale, a devastating pest that was wreaking havoc on California's orange industry in the late 19th century. The book provides a detailed account of Koebele's observations and discoveries during his trip, including the identification of several species of parasitic wasps and ladybugs that preyed on the scale. These discoveries played a crucial role in the development of biological control methods for the Fluted Scale, and ultimately led to the successful management of this invasive pest. The book offers a fascinating glimpse into the early days of biological control and the pioneering work of scientists like Albert Koebele, whose research laid the foundation for modern pest management practices.

Paperback. Etat : New. Print on Demand. This book presents a collection of studies on parasitic and predatory insects in New Zealand, Australia, and nearby islands. The author, who had been commissioned by the California State Board of Horticulture, intended to introduce these insects to California to combat the state's scale insect infestations. His notes and descriptions of the insects, collected over several months, were published by the U.S. Department of Agriculture. The book offers insights into the natural enemies of scale insects, the food habits of various coccinellid species, and the potential for biological control of these pests. The author provides a detailed account of the insects' life cycles, their effectiveness in controlling different scale species, and the challenges faced in introducing them to a new environment.

Paperback. Etat : New. Print on Demand. This book delves into the efforts to control the devastating Fluted Scale, a pest that threatened the citrus industry in the late 19th century. The author, a special agent sent from the United States Department of Agriculture, chronicles his journey to Australia and New Zealand, where he studied the scale's natural enemies. Through his meticulous observations, he discovered a predatory beetle, later known as the Cardinal Vedalia, which proved instrumental in controlling the scale infestation. The book offers a fascinating glimpse into the world of entomology and the delicate balance of ecosystems. It highlights the significant role of biological control in combating agricultural pests and emphasizes the value of scientific research in safeguarding our natural resources.
