Abstract: The effect of cultivars of ivy geranium, Amblyseius cucumeris and additional pollen on feeding damage rating of Frankliniella occidentalis was studied. The results showed that pollen had no effect on feeding damage rating, Cultivars had significant effect on feeding damage rating, there also had an interaction between cultivar and A. cucumeris. The feeding damage rating was higher on cultivar Sybil Holmes than on Amethyst 96 under the same predator treatment. A. cucumeris had different effects on different cultivars, on cultivar Sybil Holmes, the feeding damage rating was not significant different with or without predators, but on cultivar Amethyst 96, high predator: prey ratio had lower feeding damage rating than lower ratio and no predator.

Key words: Frankliniella occidentalis, Amblyseius cucumeris, Feeding damage rating, Pollen, Ivy geranium
