Synopsis

Beneficial and injurious insects come to life through this detailed season in California and beyond.

This report spans the importation of helpful insects from Australia and New Zealand, the care and life history work behind them, and practical trials against local pests. It also chronicles field notes on outbreaks, beet and scale insects, and the use of fumigation and other control methods.

The volume documents how a major funding effort brought a variety of beneficial insects to California for release and study. It details care, testing, and the life histories of the imported species, with emphasis on how they interact with local pests and crops. The work alongside measures like hydrocyanic acid fumigation and field treatments shows a practical approach to protecting fruit trees and sugar beets.

• Accounts of imported species such as Vedalia beetles and other ladybird relatives and their effectiveness against scale insects.
• Notes on practical controls including fumigation methods and their adoption by city and county agencies.
• Field observations of injurious insects in California and neighboring states, including caterpillars, beetles, and beet pests.
• Life-history details and trials that inform ongoing management of pests in fruit orchards and crops.

Ideal for readers seeking historical methods and field-tested strategies in practical entomology and crop protection.
