The globalisation and the increasing international trade have raised the number and risk of introduction of foreign species and invasive pests for years. Although native species have adapted to the native habitat over many years and generations, invasive intruders often possess characteristics that are superior to native species. Thus, and because of a lack of natural enemies, they bear the potential of decimation or complete displacement of the native species; furthermore, the introduction of pathogens or nematodes as a vector possesses a high damage potential. The available measures of the local plant protection services to combat invasive species are confined. They are limited to the felling of infested trees or plants and regular controls within the infested area. A spread of single infestations can thereby be prevented, but undetected infestations can unimpededly spread, which points out the main challenge: the detection of the species. This concerns the infestation in open land as well as the single animal on its path of introduction. Concerning the development of new adequate detection systems for invasive species, there is only little research activity going on. For other fields like detection of explosives or narcotics, the research activities date back for more than one decade and consequently there are detection systems available, which are, for example, used for explosive detection in airports. The detection principle bases on the chemistry of these substances.
Die Optimierung von Produktionsprozessen steht im Vordergrund jedes Produzenten, vor allem im Hinblick auf den optimalen Erntezeitpunkt. Zur Pflückreife sollen Kirschen als nicht-klimakterische Früchte eine optimale und hochwertige Fruchtqualität aufweisen, eine ausreichende Anzahl an Erntehelfern, Pflückhilfen, Transportkisten, Sortier- und Lagereinrichtungen sowie Absatzwege vorhanden sein. Aus diesem Grund entwickelten Wissenschaftler in der Vergangenheit diverse Reifeindices und Erntemodelle zur Bestimmung des optimalen Erntezeitpunkts von Früchten, erst an Äpfeln, dann für Steinobst.
