Abstract or Summary
  • With increasing use of new pesticide formulations worldwide to repel and kill unwanted organisms, negative consequences on non-target species such as honey bees and other pollinators are of increasing concern and not well studied. This study compares the nanotechnology based pesticide (NBP) Safari and its base neonicotinoid, dinotefuran, and their effect on bee death using liquid chromatography tandem mass spectrometry (LC-MS/MS). This research examines whether nanotechnology based pesticides, with particles smaller than pollen, can transfer more readily to the bees than the active ingredient alone and does the NBP have a longer residual toxicity to bees. This transfer can occur in the same manner that pollen is transferred from flowers to bees, or the particles may cling to pollen which is then collected by bees and returned to the hive.
