Headspace collection of grapevine volatiles in a Hungarian vineyard.

L. botrana is a major pest of the grapevine, the larvae is feeding on the flower buds and the berries. Because of the damage of the larvae, secondary fungal infection can be evolved by the grey mold (Botrytis cinerea). A special blend of plant volatiles are emitted by the host plant. Mated L. botrana females use olfactory cues to find their host plant and oviposition sites. Grapevine volatiles were collected in 2012 and the blend was analyzed with GC, numerous compounds were present in the collected blend. More grapevine volatiles will be collected in 2013, in several phenological stadia of different grapevine varieties.
