Risk assessment requires several bee species to address species-specific sensitivity to insecticides at field-realistic concentrations [PDF]
Scientific Reports, 2023 In the European registration process, pesticides are currently mainly tested on the honey bee. Since sensitivity data for other bee species are lacking for the majority of xenobiotics, it is unclear if and to which extent this model species can ...
