Abstract

Different types of plant resistance against the greenhouse whitefly, Trialeurodes vaporariorum, were distinguished according to the tissue location of the resistance factors. The effects of resistance factors were compared by measuring the electrically monitored and visually observed probing and feeding behaviour of whiteflies on two resistant tomato genotypes (82207 and 82216), a susceptible tomato cultivar, and a non-host plant, sweet pepper. On sweet pepper, whiteflies displayed very short first probes, very long pathway probing and spent much time on non-feeding activities such as walking and standing still. Also, a high percentage of whiteflies rejected sweet pepper without ingesting substances from the phloem vessel. These data suggest a strong resistance that is based on the factors present in surface/epidermis and/or mesophyll layers of this plant. The behaviour of whiteflies on tomato 82207 was very different from that on sweet pepper. On tomato 82207 whiteflies apparently did not perceive resistance factors on the leaf surface and in the mesophyll. Resistance factors appeared to be present in the phloem tissue, because a higher number of phloem phases, longer phloem salivation periods and shorter phloem ingestion periods were observed when compared with the susceptible tomato cultivar. Tomato 82216 showed no clear resistance factor in the phloem. The importance of combined EPG and behavioural research for host-plant resistance studies are discussed.
