Do we need host plant material inside CIRCE cages for mating disruption tests?


Abstract: CIRCE cage tests have been widely applied to assess the effectiveness of various mating disruption systems. Studies were conducted to assess whether the presence or absence of plants inside these cages affects the outcome of such tests. Results from cage experiments with Cydia pomonella in apple demonstrate that the presence of the host plant has a significant effect on the level of male-female moth communication disruption measured. These results suggest that future use of CIRCE should include host plants within the cage.
