图书描述

The collapse of the ubiquitous honey bee population during the past 20 years has caused a pollination vacuum for many crops. Surveys and grower experience indicate that a crisis exists in pollinator populations. This book is a practical research-based guide to using bees for crop pollination. It emphasizes conserving feral bee populations as well as more traditional methods of culturing honey bees and other bees. There are three main sections that address the biology of pollination, culturing and managing bees for optimum crop pollination, and individual crop pollination requirements and recommendations. This last section includes 42 short chapters on different crops.
