Tenebrionidae is a diverse insect family of Coleoptera that shows high levels of endemicity in epigean species. For the Andean region, which is divided into three subregions: Central Chilean, Subantarctic and Patagonian, it has been hypothesized that epigean tenebrionids have diversified in the Patagonian subregion and subsequently, they dispersed to Subantarctic and Central Chilean subregions....

Callyntra Solier, 1836 is a genus mainly from Chile, with one species occurring in Argentina, which currently contains 20 described species. Recent explorations in the Andes Mountain Range in Chile, have resulted in the collection of specimens morphologically different from all previously described species. The aim of this paper is to describe a new species of Callyntra, discuss its relationshi...

Hylastes spp. (Coleoptera: Scolytidae) were evaluated as potential vectors of Leptographium spp. fungi. Bark beetles were trapped from stands ofloblolly pine, Pinus taeda L., exhibiting a range of decline symptoms in central Alabama. Under controlled conditions, field-collected adult Hylastes salebrosus Eichoff (Coleoptera: Scolytidae) and Hylastes tenuis Eichoff (Coleoptera: Scolytidae), which...

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...

Carabid beetles (Coleoptera, Carabidae) are one of the most studied soil groups in relation to heavy metal (HM) accumulation and use for bioindication of environmental pollution. Accumulation of Zn and Cu in carabid beetles was species-, sex- and trophic group-specific. No differences were found in HM contents between omnivorous and carnivorous species. The use of carabid beetles as indicators ...

The response of bark beetle predators and woodboring beetles to the bark beetle anti-aggregation pheromone, verbenone, was tested in the field with multiple-funnel traps baited with attractant kairomones. Catches of the predators Thanasimus undatulus (Say), Enoclerr~~ sphegeus (F.) , Erwclaus lecontei (Wolcott) (Coleoptera: Cleridae) , and hcono tu .~ complex LeConte (Coleoptera: Colydiidae) de...

This is the first study on the distribution and occurrence of Helicosporidium sp. in the populations of the great spruce bark beetle Dendroctonus micans (Coleoptera: Curculionidae, Scolytinae) from different localities. Two hundred and eight of 2300 examined beetles were infected by Helicosporidium sp. In total infection rate was 9.04%. The infection reached 71.7%. The prevalence of Helicospori...

A survey on the click beetles (Coleoptera, Elateridae) in province of Kurdistan (Iran), with three new records for Iranian fauna

Bark beetles (Coleoptera: Scolytinae) are known to be associated with fungi, especially species of Ophiostoma sensu lato and Ceratocystis. However, very little is known about these fungi in Spain. In this study, we examined the fungi associated with 13 bark beetle species and one weevil (Coleoptera: Entiminae) infesting Pinus radiata in the Basque Country of northern Spain. This study included ...
