The findings of the Task Force on Systemic Pesticides (TFSP): • Both neonicotinoids and fipronil exhibit extremely high toxicity to most arthropods and a lower toxicity to vertebrates (although fipronil exhibits high acute toxicity to fish and some bird species). • neonicotinoids can persist for years in soils and so cause environmental concentrations to build up if regularly used...killing soil invertebrates • Dust created during drilling of treated seeds is lethal to flying insects and has caused large-scale acute losses of honeybee colonies. • detected at much higher concentrations in guttation drops exuded by many crops. In bees, consumption of such contaminated food leads to impaired learning and navigation, raised mortality, increased susceptibility to disease via impaired immune system function and reduced fecundity...
