After a first case in Switzerland of summer fruit tortrix (A. orana) resistance detected in Etoy in 2004, followed by a second in Aigle in 2005, a pre-bloom treatment with lufenuron failed in 2006 in Founex. The larvae collected in that orchard in July on the damaged shoots allowed to test some insecticides applied either by dipping of leaves or by incorporation to the artificial diet. Like the population of Etoy, the strain of Founex was resistant to lufenuron, tebufenozide, methoxyfenozide and fenoxycarb. Compared to the susceptible strain, the resistance factor of these two populations to fenoxycarb, tested on artificial medium, reached approximately 1000.
