With special traps on colonies of Apis mellifera L. to measure daily pollen collection by the bees it was shown that when the alfalfa field they were in was sprayed with 3 Ib toxaphene and 0.5 Ib endosulfan per acre and a safflower field ⅓ mile away was sprayed with 0.5 Ib naled per acre pollen gathering, and presumably nectar gathering, were reduced by half. Damage to the colony in pollen collection lasted several days. The naled spray on safflower caused most of the damage.
