The effect of blue and UV light-emitted diodes (LEDs) on the disturbance of the whitefly natural enemies Macrolophus pygmaeus and Encarsia formosa

open access: yesBiological Control
Recent studies demonstrated that blue and UV light effectively disturb greenhouse whiteflies (Trialeurodes vaporariorum) from a host plant (“push”), enhancing their capture on attractive traps after dispersal (“pull”).
