The species of the genus Charisius Champion, from Mexico and Central America are reviewed. The flightless genus Narses Champion, with one included species, N. subalatus Champion, is placed in synonymy with the genus Charisius. Four new species are described and illustrated, C. granulatus and C. punctatus (from Guatemala) and C. apterus and C. howdenorum (from Mexico). Charisius subalatus (Champ...

We evaluated the efÞcacy of the systemic insecticides dinotefuran, emamectin benzoate, Þpronil, and imidacloprid for preventing attacks and brood production of southern pine engraver beetles (Coleoptera: Curculionidae: Scolytinae) and wood borers (Coleoptera: Cerambycidae) on standing, stressed trees and bolt sections of loblolly pine, Pinus taeda L., in eastern Texas. Emamectinbenzoate signiÞc...

In order to contribute to the knowledge of beetles (Coleoptera) of the mountainous region of Morocco, Talassemtane National Park (Western Rif, Chefchaouen district, Morocco) was surveyed. This is an exceptional protected area of the Mediterranean Intercontinental Biosphere Reserve (RIBM). The checklist was made using different traps combined with active periodical searches during 2013-2015. A t...

Members of the order Coleoptera are sometimes referred to as 'living jewels', in allusion to the strikingly diverse array of iridescence mechanisms and optical effects that have arisen in beetles. A number of novel and sophisticated reflectance mechanisms have been discovered in recent years, including three-dimensional photonic crystals and quasi-ordered coherent scattering arrays. However, th...

Carrion beetles are important in terrestrial ecosystems, consuming dead mammals and promoting the recycling of organic matter into ecosystems. Most forensic studies are focused on succession of Diptera while neglecting Coleoptera. So far, little information is available on carrion beetles postmortem colonization and decomposition process in temperate biogeoclimatic countries. These beetles are ...

The efficiency of fenced pitfall traps for estimating the density of commonly occurring epigeal predatory beetles was examined using mark-release-recapture. Most beetles of those recovered were recaptured within one week of their release. For seven of the ten species tested recapture rates were over 70%, with higher rates for the larger species. The predatory arthropod species composition captu...

Root and lower stem insects cause significant damage to conifers, vector phytopathogenic fungi, and can predispose trees to bark beetle attacks. The development of effective sampling techniques is an important component in managing these cryptic insects. We tested the effects of trap type and stereochemistry of alpha-pinene, in combination with ethanol, on catches of the root colonizing weevils...

A new genus, Pumiliofossorum Silvestro & Giraldo gen. nov. (Tenebrioninae: Scotobiini) and two new Peruvian species, Pumiliofossorum moche Silvestro & Flores sp. nov. and P. sechurae Giraldo & Flores sp. nov. are described and illustrated. Distributional data, habitat records, photographs, and SEM images are included. A revised key for the six genera of Scotobiini is provided. Morphology of the...

Specimens of two different species beetles, representing that many separate families Coleoptera, are herein reported as new to Wisconsin. These occur respectively within the following families: Zopheridae and Trogossitidae.

numerous species of insects have been recorded from various types of manure in commercially reared birds from different parts of the world. this study was carried out to determine parasitic beetle populations in commercial rearing house litter from different regions of the west azerbaijan province in iran. atotal of 60 samples of litter were collected from june 2008 to november 2009 from 20 pou...
