Project (1)
Little is known about the impacts of climate change to new and innovative controlling methods in agriculture using semiochemicals. Some systems may be jeopardized by the impacts of climate change in particular levels. Semiochemicals could be used as monitoring tools for determining exact spraying dates with possibilities to reduce the overall amount of insecticides or as lure for mass trapping. Further, sex pheromones can be used to disrupt the communication between conspecific insects. The latter is known as mating disruption. But climate change can potentially affect all levels of olfactory communication among and between insect that are mainly mediated by infochemicals. The aim of the project is to determine the effects of fundamental determinants of climate change (higher average temperatures, elevated CO2- and ozone-levels) on the perception and reaction of insects to semiochemicals, to find possible limitations for controlling methods based on semiochemicals and to find solutions to keep these systems working. The results will help by the development and improvement of innovative control methods for plant protection in fruit crops and viticulture like the mating disruption method and facilitating the reduction of greenhouse gases during production and application of insecticides.
