Oviposition and feeding by Bactericera cockerelli (Homoptera: Psyllidae) in response to a solar protectant applied to potato plants

► The limestone particle film (Purshade®) reduces potato psyllid oviposition. ► A plant growth regulator prohexadione-calcium (Apogee®) has no effect on probing or oviposition. ► Further research on use of limestone films in potato psyllid management is justified.
