Small Cages with Insect Couples Provide a Simple Method for a Preliminary Assessment of Mating Disruption
Figure 4
Effect of the number of couples exposed on the percentage of E. ambiguella females mated in field cages (mesh size = 1500 μm, containing no pheromone dispenser). The notation μg/day represents the approximate daily emission rate of pheromone dispensers for E. ambiguella; data from the three insect control schemes were fitted with linear regression models.
