Resumen:
a b s t r a c t
Mating disruption is now widely used in apple growing regions where control of codling moth is
dif.cult due to insecticide resistance. This strategy comprises the slow release of pheromone from
controlled delivery dispensers placed on the crop .eld with the aim to attract and/or confuse males
impeding mating. The success of the technique strongly depends on maintaining an adequate
pheromone concentration in the air within the crop. At present, monitoring of the sexual confusion
ef.ciency is done by hand using lures and traps and carrying out a weekly evaluation of the trapped
insects, which involves human resources and consumes considerable time and effort.
This article describes the use of an electronic nose capable of detecting and discriminating low
amounts of codling moth pheromone (codlemone) immersed in a background odour of plants and fruit
volatiles. Laboratory results obtained indicate the feasibility of using a trained electronic nose for
tracking in real-time aerial concentration levels of codlemone against a background of common apple
host volatiles. Continuous .eld monitoring can potentially be achieved by combining the electronic nose
with automated robotic navigation and remote transference of data.
