Fipronil is toxic to bees and should not be applied to vegetation when bees are foraging. [27] Based on ecological effects, fipronil is highly toxic to upland game birds on an acute oral basis and very highly toxic on a subacute dietary basis, but is practically nontoxic to waterfowl on both acute and subacute bases. [6]
The acute toxicity of pesticides on bees, which could be by contact or ingestion, is usually quantified by LD 50. Acute toxicity of pesticides causes a range of effects on bees, which can include agitation, vomiting, wing paralysis, arching of the abdomen similar to sting reflex, and uncoordinated movement. Acute toxicity may depend on the mode ...
The introduction of certain chemical substances—such as ethanol or pesticides or defensive toxic biochemicals produced by plants—to a bee's environment can cause the bee to display abnormal or unusual behavior and disorientation. In sufficient quantities, such chemicals can poison and even kill the bee. The effects of alcohol on bees have ...
Fipronil is a phenylpyrazole insecticide, with a broad-spectrum systemic mode of action. Fipronil is designed to eliminate insects similar to bees, such as yellowjackets (Vespula germanica) and many other colonial pests by a process of 'toxic baiting', whereby one insect returning to the hive spreads the pesticide among the brood. [161]
Research suggests potential toxicity to honey bees and other beneficial insects even with low levels of exposure, with sublethal effects that negatively impact the survival of colonies. In lab studies, neonicotinoids were shown to increase mortality rates [ 102 ] and negatively affect the ability to fly [ 103 ] and forage in exposed bees. [ 104 ]
The Wikipedia article on Fipronil suggests that Fipronil could be considered the main cause of bee colony collapse, but the current article fails to mention Fiponil at all. Inconsistent. Since fipronil is for killing ants the link to bees is certainly suggestive. JPLeonard 21:20, 19 May 2019 (UTC)
