High levels (500-1O0Ox) of endosulfan resistance in the coffee berry borer Hypothenemus hampei (CBB) (Coleoptera: Scolytidae) have developed in five important coffee ( C o f f a canephora var. robusta) producing areas on the east coast of New Caledonia (Brun et al 1989, 1990). Coffee is grown in New Caledonia in small (0.25 ha) plantations as a key cash crop, but infestations of CBB can reach 30-100% if not adequately controlled. Detection of endosulfan resistance occurred after 8 years of
