Nowadays to ensure better plant production various artificial light sources are used in greenhouses. Light in terms of photoperiod length, wavelength and temperatures is one of the most important factors in the insect life. Whiteflies Trialeurodes spp. are known to feed on many plant species, including agriculturally important ones, and in favourable conditions can rapidly reproduce and cause vast plant damage. During our monitoring the significant increase of whitefly numbers was observed under high-pressure sodium vapor lamps Helle Magna com-pared to LED and induction lamps.
