Cyantraniliprole: Pollinator profile of the novel insecticides under laboratory, semi-field and field conditions

Background: The pollinator profile of cyantraniliprole, a systemic anthranilicdiamide insecticide, with foliar or soil applications between 12.5 to 150 g a.s./ha, was investigated. Results: Cyantraniliprole- tested up to maximum water solubility level – caused no increased acute oral or contact honeybee mortality. The lowest LD50 values for formulated cyantraniliprolewere 0.39 (oral) and 0.63 (contact) μg cyantraniliprole/ honeybee, respectively. The oral toxicity of 4 plant metabolites was maximally similar to cyantraniliproleor no oral toxicity was determined up to maximal water solubility level. Cyantraniliprolespray deposits at 150 g a.s./ha and aged for ≥ 3 hours pose low risk for honeybees. Cyantraniliproleuse may results in residues in pollen and nectar, but oral honeybee risk assessments indicate low risk for honeybees via oral exposure. In semi-field and field honeybee tests low risk for honeybees was confirmed. Tomato greenhouse study results demonstrate that there is an excellent fit between the use of bumblebees ( Bombus terrestris) for pollination and cyantraniliprole– applied either via spray or drip irrigation. Conclusion: Based on a comprehensive data package it was found that the intended uses of DuPont cyantraniliproleformulations pose low risk for pollinators.
