AI Article Synopsis

  • Researchers identified volatile compounds emitted by male Platypus mutatus while they bore galleries in poplar trees, using advanced analysis techniques.
  • They found that the main compounds involved were 6-methyl-5-hepten-2-ol (sulcatol) and 6-methyl-5-hepten-2-one (sulcatone), with only one form of sulcatol (retusol) present.
  • Behavioral tests indicated that female Platypus mutatus are more attracted to the galleries of males, which suggest that these compounds may act as sex pheromones to attract females.

Article Abstract

We report here the identification and behavioral activity of volatile compounds emitted by male Platypus mutatus (=sulcatus) Chapuis while boring galleries in living poplar, Populus deltoides Marshall, trees. Headspace analysis using solid phase microextraction techniques showed the presence of 6-methyl-5-hepten-2-ol (sulcatol) and 6-methyl-5-hepten-2-one (sulcatone). Only one enantiomer of sulcatol, retusol, was found to be part of the volatile emission. Behavioral assays showed that females are more attracted than males to galleries with boring males inside. Both sulcatol and sulcatone elicited electroantennographic responses by female P. mutatus. Furthermore, behavioral bioassays showed that both sulcatol and sulcatone elicit behaviorally attractive responses by females. These results suggest that male P. mutatus releases a sex pheromone composed mainly of retusol and sulcatone.

Megaplatypus mutatus (=Platypus sulcatus Chapuis) is an Ambrosia beetle native to South America, which was recently introduced in Italy and its presence there is causing severe damage to the local poplar plantations. The male M. mutatus pheromone is composed of (S)-(+)-6-methyl-5-hepten-2-ol [(+)-sulcatol], 6-methyl-5-hepten-2-one (sulcatone) and 3-pentanol.

The hardwood of Caesalpinia echinata Lam. (brazilwood, Pernambuco, ibirapitanga) is currently the most profitable material used for violin bow due to the unique vibrational properties and dimensional stability. Although this species is resistant to the wood decay caused by termites and rot fungi, an experimental plantation in Southeastern Brazil has been attacked by the ambrosia beetle Platypus mutatus Chapuis (= Megaplatypus mutatus and P.
