This Citrus NZ-ALT resistance management case study covers Kelly’s citrus thrips (KCT), one of the most serious pests affecting citrus production in New Zealand, particularly lemons, limes, oranges and mandarins.
KCT damages fruit during early development, causing cosmetic scarring that reduces export quality and market value. Citrus growers rely on a narrow range of modes of action, which increases the risk of resistance.
In this resource, the resistance problem, the search for new control options and the four principles of the New Zealand citrus integrated pest management (IPM) framework for pest and disease control are explained. The management of KCT using IPM and the thresholds for KCT for varieties of citrus are also included.
