The softwood communities found there are unique habitats for many butterflies. The studies conducted in the vicinity of Göttingen resulted in 83 Makrolepidoptera taxa found on willow (Salix caprea) and 65 on poplar (Populus tremula). Since different plants emit different volatiles, many insects are able to follow the odour plumes and find their hosts by perceiving various odours. The emission of volatiles can be influenced by different external factors, like surplus of salts, drought, mycorrhiza. A gas-chromatograph with mass-spectrometric and parallel electroantennographic detector (GC-MS/EAD) was employed to measure in what way the volatile pattern changed and which of the associated chemical substances could be detected by the insect antennae. The volatile pattern is very important for butterflies to find their habitat."],["dc.identifier.gro","3149773"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6471"],["dc.language.iso","de"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.publisher","Vorstand der DGaaE"],["dc.publisher.place","Halle"],["dc.relation.conference","Entomologentagung"],["dc.relation.crisseries","Mitteilungen der Deutschen Gesellschaft für allgemeine und angewandte Entomologie"],["dc.relation.eventend","2005-03-24"],["dc.relation.eventlocation","Dresden, Germany"],["dc.relation.eventstart","2005-03-21"],["dc.relation.ispartof","Vorträge der Entomologentagung in Dresden vom 21. bis 24.

However, examination of the chemical ecology of insects has focussed up to now on insects living above ground. Evidence for behavioral responses to chemical cues in the soil other than CO2 is scarce and the role played by olfaction in the process of finding host roots below ground is not yet understood. The question of whether soil-dwelling beetle larvae can smell their host plant roots has been under debate, but proof is as yet lacking that olfactory perception of volatile compounds released by damaged host plants, as is known for insects living above ground, occurs. Here we show that soil-dwelling larvae of Melolontha hippocastani are well equipped for olfactory perception and respond electrophysiologically and behaviorally to volatiles released by damaged host-plant roots. An olfactory apparatus consisting of pore plates at the antennae and about 70 glomeruli as primary olfactory processing units indicates a highly developed olfactory system. Damage induced host plant volatiles released by oak roots such as eucalyptol and anisol are detected by larval antennae down to 5 ppbv in soil air and elicit directed movement of the larvae in natural soil towards the odor source. Our results demonstrate that plant-root volatiles are likely to be perceived by the larval olfactory system and to guide soil-dwelling white grubs through the dark below ground to their host plants. Thus, to find below-ground host plants cockchafer larvae employ mechanisms that are similar to those employed by the adult beetles flying above ground, despite strikingly different physicochemical conditions in the soil."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2012"],["dc.identifier.doi","10.1371/journal.pone.0045827"],["dc.identifier.isi","000309388500015"],["dc.identifier.pmid","23049688"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8223"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/25266"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Public Library Science"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.title","Cockchafer Larvae Smell Host Root Scents in Soil"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
