Effect of Trap Color on Captures of Bark-and Wood-Boring Beetles (Coleoptera; Buprestidae and Scolytinae) and Associated Predators.

Traps baited with attractive lures are increasingly used at entry-points and surrounding natural areas to intercept exotic wood-boring beetles accidentally introduced via international trade. Several trapping variables can affect the efficacy of this activity, including trap color. In this study, we tested whether species richness and abundance of jewel beetles (Buprestidae), bark and ambrosia beetles (Scolytinae), and their common predators (i.e., checkered beetles, Cleridae) can be modified using trap colors different to those currently used for surveillance of jewel beetles and bark and ambrosia beetles (i.e., green or black). We show that green and black traps are generally efficient, but also that many flower-visiting or dark-metallic colored jewel beetles and certain bark beetles are more attracted by other colors. In addition, we show that checkered beetles have color preferences similar to those of their Scolytinae preys, which limits using trap color to minimize their inadvertent removal. Overall, this study confirmed that understanding the color perception mechanisms in wood-boring beetles can lead to important improvements in trapping techniques and thereby increase the efficacy of surveillance programs.

A revision of the Anthaxia (Anthaxia) midas Kiesenwetter, 1857 species-group (Coleoptera: Buprestidae: Anthaxiini).

The Anthaxia (Anthaxia) midas Kiesenwetter, 1857 species-group is defined and revised. A new species from Turkey, A. (A.) cebecii sp. nov., is described and compared to its most similar species. A. midas oberthuri Schaefer, 1938 is elevated to the rank of species, and a lectotype is designated. A. (A.) spathuligera Obenberger, 1924 and A. (A.) midas muelleri Obenberger, 1925 are reconfirmed synonyms of A. midas Kiesenwetter, 1857.All species of the new species-group are illustrated, including the hitherto unknown male of A. (A.) patsyae Baiocchi, 2008, all type specimens and original data labels. In addition to diagnostic characters, informations on the distribution, biology and taxonomic position of each species are also presented, together with a short definition of the new species-group, and a key to its species.

Description of a new species of Anthaxia Eschscholtz, 1829 from Jordan, with notes on the Anthaxia winkleri species-group (Coleoptera, Buprestidae).

A new species of Anthaxia Eschscholtz, 1829 endemic to Jordan, Anthaxia (Haplanthaxia) nabataea sp. nov., is described and illustrated. The new taxon is compared to its most similar species, and data about its distribution, bionomy and taxonomic position are given, together with some notes on the Anthaxia (Haplanthaxia) winkleri species-group.
