What is Being Done to Reduce Danger of Poisoning? 



1. Research on comparative toxicities of pesticides to bees. 

 This provides information of value in making recommenda- 

 tion for the use of such materials. 



2. Investigations on possible use of substances repellent to 

 bees. These would be included in sprays in order to cause 

 bees to avoid treated surfaces.
