Resistance of some rose cultivars to the western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae)

Abstract
Some rose cultivars such as City of Belfast are more resistant to the western flower thrips, Frankliniella occidentalis (Pergande) than others. Data from life tables and behavioural studies indicate that the reason for resistance may be physiological-chemical as well as the physical structure and colour of the flower. Some rose odours repelled F. occidentalis.
