In California, commercially managed honey bees are used to pollinate over 50 varieties of orchard and field crops. The state's $1.189 billion almond crop is entirely dependent on honeybee pollination. Some other crops dependent on honeybee pollination include apples, avocados, cherries, cucumbers, melons and sunflowers.
From our colleagues at Oregon State University Extension comes this overview of how a variety of wild and managed bees and their pollination activities are affected by pesticide application. Provides guidelines for how beekeepers, growers, and pesticide applicators can work together to prevent bee poisoning. Tables provide specific information regarding toxicity of insecticides, miticides and blossom and fruit thinning agents to honey bees; to alfalfa leafcutting bees; to alkali bees; and to bumble bees.
