DDT has been found to be highly toxic to bees, both as a contact 
insecticide and as a stomach poison. If !JDT ever comes into general use 
as an insecticide, it conceivably might upset the balance of natural con- 
ditions by destroying the pollinators that produce many of our food orops.

—Bromley (96). 
Small cottkn plants were dusted with 3-peroent DDT dust (A-3) at 
the rate of 26 to 30 pounds per acre. Honeybees usually flew directly 
to freshly opened flowers and therefore usually did not alight on dust- 
ed surfaces; the feir bees that did orawl over the braots and corolla 
into the flower showed little or no apparent effeot of the inseotioide.
