4apillary gas chromatography and mass spectrometry were used to quantify the amounts of Eand Zchalcogran and methyl (E,Z)-2,4-decadienoate (E,Z-MD), pheromone synergists of the bark beetle Pitygenes chalcographus (Coleoptera: Scolytidae). Males were exposed or not to vapours of host (Norway spruce, Picea abies) oleoresin or allowed to feed in host logs prior to extraction of body parts and hind...

After almost two decades of stagnation, the taxonomy New World Scarabaeinae dung beetles has since 1988 been going through a period great effervescence. In last 35 years, 81 complete revisions and 69 supplements have produced by 86 authors based in 15 countries, addressing taxonomic status 950 species. This is what we christen as Taxonomic Revolution beetles. We review history products this rev...

The earliest known fossil beetle † Coleopsis archaica is re-examined using Reflectance Transformation Imaging (RTI). morphological observations are evaluated with respect to phylogenetic implications and the early evolution of Coleoptera. belongs an Permian branch beetles, outside a monophyletic unit comprising Coleoptera (in widest sense) excluding †Tshekardocoleidae. This clade mainly charac...

Beetles comprise about 400,000 described species, nearly one third of all known animal species. The enormous success of the order Coleoptera is reflected by a rich diversity of lifestyles, behaviors, morphological, and physiological adaptions. All these evolutionary adaptions that have been driven by a variety of parameters over the last about 300 million years, make the Coleoptera an ideal fie...

The morphology and diet characteristics of three Myotis species roosting in the same cave were studied in Anlong County, Guizhou from September to November 2005. The three mouse-eared bats were the Chinese water myotis (Myotis laniger) "body mass: (4.46±0.53) g, forearm: (34.63±1.45 mm)", fringed long-footed myotis (Myotis fimbriatus) "body mass: (5.15±1.76) g, forearm: (35.20±1.07) mm" and sze...

Detection tools are needed for Monochamus species (Coleoptera: Cerambycidae) because they are known to introduce pine wilt disease by vectoring nematodes in Asia, Europe, and North America. In 2012–2014, we examined the effects of the semiochemicals monochamol and ipsenol on the flight responses of the sawyer beetles Monochamus carolinensis (Olivier), Monochamus clamator (LeConte), Monochamus m...

Eucolaspis Sharp 1886 is a New Zealand native leaf beetle genus (Coleoptera: Chrysomelidae: Eumolpinae) with poorly described species and a complex taxonomy. Many economically important fruit crops are severely damaged by these beetles. Uncertain species taxonomy of Eucolaspis is leaving any biological research, as well as pest management, tenuous. We used morphometrics, mitochondrial DNA and m...

Mitochondrial gene order in Coleoptera has been thought to be conservative but a survey of 60 complete or nearly complete genomes revealed a total of seven different gene rearrangements (deletions, gene order reversals), mainly affecting tRNA genes. All of these were found to be limited to a single taxon or a subclade of Coleoptera. The phylogenetic distribution of a translocation of tRNA(Pro) ...

Stemmata, the eyes of holometabolous insect larvae, have gained little attention, even though they exhibit remarkably different optical solutions, ranging from compound eyes with upright images, to sophisticated single-chamber eyes with inverted images. Such optical differences raise the question of how major transitions may have occurred. Stemmata evolved from compound eye ancestry, and optica...

The fog-basking beetle, Onymacris unguicularis (Haag, 1875), is currently listed as a polytypic form comprising two subspecies. A flightless substrate specialist, the beetleis endemic to vegetationless dunes in the Namib, where southern populations constitute the nominate subspecies, O. u. unguicularis, and populations some 300 km to the north compose O. u. schulzeae Penrith, 1984. Their taxono...
