	abstract = {Megaplatypus mutatus (=Platypus mutatus) is an ambrosia beetle native to South America. Unlike most ambrosia beetles, it attacks only living trees, penetrating the xylem of its host by boring long tunnels. These galleries cause severe stem-breakage and mortality in commercial poplar plantations. In previous studies we showed that volatile emissions from pioneer male M. mutatus are composed of (+)-6-methyl-5-hepten-2-ol, 6-methyl-5- hepten-2-one and 3-pentanol. Recently, we developed reservoir type controlled release dispensers and tested the efficacy of various trap designs in the field. Results showed that black cross-vane traps (CIPEIN-CV) captured significantly more insects than other traps designs baited with the same dispensers. In the present study we modified the colour, the construction material and the size of traps with the aim of increasing trapping efficacy and reducing the final trap cost. The results showed that significantly more female and male M. mutatus were captured in small and large traslucent traps (CIPEIN-CVt) than in black CIPEIN-CV trap. Furthermore, traslucent CIPEIN-CVt trap costs were significantly lower than costs for CIPEIN-CV traps. Significantly improved trapping efficacy with an important decrease in final costs will allow detection of considerably lower populations of M. mutatus in monitoring programs.

	abstract = {Megaplatypus mutatus (= Platypus mutatus) (Chapuis), an ambrosia beetle (Coleoptera: Platypodidae) native to South America, is a forest pest that attacks live standing trees, affecting commercial poplar and other broadleaf plantations. Traditionally, single-chambered emergence traps have been used to collect live beetles for field and laboratory studies. However, the lack of separation in these chambers results in antagonistic interactions between individuals. Wounded M. inutatus are incapable of successful reproduction and are of little value in physiological and behavioral experiments. We introduce a new, multiple-chambered trap that isolates individual insects until collection, thus increasing the number of uninjured and fully functional insects available for physiological and behavioral experiments.},

	abstract = {Megaplatypus mutatus (Chapuis) is a native South American ambrosia beetle that attacks live hardwood trees (e. g. Populus spp.), causing important economic losses to commercial plantations. Male beetles release the main components of the sex pheromone, namely (+)-6-methyl-5-hepten-2-ol ((+)-sulcatol, or retusol) and 6-methyl-5-hepten-2-one (sulcatone), when colonizing suitable hosts. The hindgut is shown to be the anatomical site of pheromone accumulation within males, the enantiomeric composition of sulcatol in this tissue is 99\%-(+) and sulcatol is first detectable in this tissue on days 1-2 after gallery initiation. Peak accumulation of sulcatol occurs on days 5-12 after gallery initiation. Trace quantities of sulcatone are also observed during the same period. Both pheromone components are present in male emissions from three host species (Populus x canadensis, Populus alba and Casuarina stricta) between days 2 and 12 after gallery initiation, although sulcatone is always present in low concentrations. The temporal patterns of sulcatol and sulcatone accumulation or storage in male M. mutatus correspond to the temporal patterns of emission.},

Previous work showed that male M. mutatus emits a sex pheromone composed mainly of (+)-sulcatol and sulcatone. We collected male volatile emissions during the hours of maximum emergence by using a specific polar microextraction phase; analyzed the extract by GC-MS; and tested the biological activity of selected compounds in the extract with a walking behavioral assay. Female M. mutatus emerged primarily between 7 and 11 h. In the chemical analyses of volatiles, a third compound, 3-pentanol, was identified in a small percentage of samples. Walking behavioral bioassays with video image analysis showed that at the doses tested, 3-pentanol elicited an attractive response from females.},

	abstract = {Megaplatypus mutatus (Chapuis) (Coleoptera: Curculionidae: Platypodinae) is an ambrosia beetle native to South America, but it has recently been introduced into Italy and represents a serious problem in commercial poplar and fruit tree plantations. Male M. mutatus emit a sex pheromone composed of (+)-6-methyl-5-hepten-2-ol ((+)-sulcatol), 6-methyl-5-hepten-2-one (sulcatone), and 3-pentanol. We performed three field trials of mating disruption of M. mutatus in hazelnut and poplar plantations in Argentina and Italy. To perform these tests, we made plastic pheromone reservoir-type dispensers for sulcatol, sulcatone, and 3-pentanol with zero-order kinetics that were deployed in the field during the female flight period. The number of galleries where mating took place was significantly higher in control than in treated areas, indicating that pheromone application had interfered with female behavior and male localization. Because damage reduction was >56\% in both countries, these results demonstrate the potential for the strategy of pheromone-mediated mating disruption of M. mutatus in commercial poplar and hazelnut plantations. Also, our study provides the first evidence for successful pheromone-mediated mating disruption in a forest beetle.},

The development of traps baited with synthetic pheromones that can be used for monitoring M. mutatus in infested poplar plantations is an important goal in preventive programs. Pioneer male M. mutatus emit a pheromone composed mainly by (+) -sulcatol and sulcatone. In the current study, we tested their release rates from several polymeric reservoir systems, to develop and manufacture a pheromone-releasing device. The efficacy of three different types of traps was evaluated in the field. Single funnel traps equipped with cross-vanes (CIEPEIN-CV) captured significantly more insects than multiple funnel traps (LINDGREN) and simple funnel traps (CIPEIN-F).},
