Bark beetles are attracted to their hosts by chemical stimuli eg. "Flavonoids..", first step in order to select their hosts. Is there any work about those stimili? Chemical extracts from the bark of "Prunus", stone fruit trees (almond, peach, plum and apricot)?
Hi Asma,
In fact, there were some interesting research studies (although linked to forest entomology) related to attraction of beetles by bark volatiles (components of essential oils: sesquiterpenes, (3Z)-Hexenol, the phenylpropene methyl chavicol (Estragole),…) released by stressed/weak host plants. Anyway, you can find out all details in the three articles I attached.
Furthermore, regarding volatile compounds (with bio-insecticide properties) liberated from Prunus biomass, you can check out the following link: http://www.patentbuddy.com/Patent/7195788
Cheers
