Impacts of Non-Insecticidal Agricultural Chemicals on Olfactory Behaviors in Bumblebees
Meeting Abstract 39.6 Thursday, Jan. 5 Impacts of Non-Insecticidal Agricultural Chemicals on Olfactory Behaviors in Bumblebees SPRAYBERRY, Jordanna/ D. H.*; RIFFELL, Jeff/ A.; Muhlenberg College; Univ. Washington jsprayberry@muhlenberg.edu Our research focuses on potential indirect effects of non-insecticidal agricultural chemicals. Agricultural chemical treatments such as fertilizers or fungicides could add to the mélange of incoming sensory information that […]
