Honey bee response to high concentrations of some new spray adjuvants


  • B.J. Donovan
  • G. Elliott




The response of honey bees when treated orally and topically to the spray adjuvants DuWett Li700 Bond and Bond Xtra each at three different concentrations was evaluated in November 2000 under the OECD Guidelines for Testing of Chemicals of 21 September 1998 The concentrations ranged from 01 to 10 the highest of which were well above those used in the field Dimethoate at three concentrations was used as a standard and for the topical test distilled water was used as a nonchemical control For both tests about 1000 honey bees from the brood combs of a healthy colony were anaesthetized with carbon dioxide from which bees were treated and held in groups of 10 in cages at 25C and 70 RH for 48 hours Each treatment was replicated three times Despite some mortality for two of the three cages of Bond Xtra at 1 when applied topically none of the adjuvants were found to be toxic to honey bees at any concentrations tested
