Mating disruption of Spilonota ocellana and other apple orchard tortricids using a multispecies reservoir dispenser.

摘要: BACKGROUND A new mating disruption formulation for population control of a wide range tortricid pests, including Spilonota ocellana, was tested in Swedish apple orchards during 2012–2013. Owing to the characteristics local agricultural landscape, evaluated isolated rather than through an area-wide approach. Parameters such as trap shutdown, communication field cages, damage level and dispenser emission were measured efficacy indicators. RESULTS The test reduced catches monitoring traps entire species. In between sexes disrupted both Adoxophyes orana Cydia pomonella. The fruit caused by leafrollers (including S. ocellana) treatment. device showed constant release all components flight activity period these pests. CONCLUSION Single-orchard experiments significant effect on populations leafroller species complex. While promising, light variability result, scouting may be required enable practitioners estimate density pests avoid possible unexpected attacks.
