Pissodes

The pheromone bouquet of the pecan weevil, Curculio caryae is similar to that of the boll weevil however, it also contains (lS,2JR)-grandisol. The quantitative composition of the blend determines whether it is more attractive to the pecan weevil or to the boll weevil [386]. In some pine weevils, Pissodes species, grandisol and the corresponding aldehyde, grandisal, are components of a male produced pheromone. In Pissodes nemorensis and Pissodes strobi grandisol... 

In the weevil Pissodes notatus (Goleoptera), single olfactory receptor neurones on the antennae were screened for sensitivity to naturally produced plant volatiles The two most abundant types responded to a-pinene, (3-pinene and 3-carene and to isopinocamphone and pinocamphone, respectively. Major as well as minor constituents of plant volatile blends were employed for host and non-host detection, mainly including monoterpenes (bicyclic and monocyclic) [382].

The synthesis of grandisol(I) and lineatin(II) is discussed. Grandisol is a pheromone component in the cotton boll weevil and in Pissodes weevils. 

Limonene inhibiting pine larva parasites feeding (Diprian pini and Dendrolymus pini) [103]. The (+)-3-thujone and (-)-3-isothujone, the main components of Thuja plicata leaves, inhibit the feeding of Pissodes on needle trees [102]. Enzymatic mechanism explaining the olfactory processes are the reasons for eliciting responses between the optical isomers and the receptors.
