The Acute Oral Toxicity of Commonly Used Pesticides in Iran, to Honeybees (Apis Mellifera Meda)
The honey bee is credited with approximately 85% of the pollinating activity necessary to supply about one-third of the world’s food supply. Well over 50 major crops depend on these insects for pollination. The crops produce more abundantly when honey bees are plentiful. Worker bees are the ones pri...

The honey bee is credited with approximately 85% of the pollinating activity necessary to supply about one-third of the world’s food supply.
