BACKGROUND Monitoring traps and control methods are needed for the long-legged chafer, Hoplia spectabilis Medvedev, which has recently reached outbreak numbers in pastureland of Qinghai Province, China. RESULTS Field trapping experiments, using cross-pane funnel (barrier) traps, showed that H. spectabilis adults were not significantly attracted to branches of the host plant Dasiphora fructico...

Recurring species interactions can cause species to adapt to each other. Specialization will increase the fitness of symbionts in the coevolved association but may reduce the flexibility of symbiont choice as it will often decrease fitness in interactions with other than the main symbiont species. We analyzed the fitness interactions between a complex of two cryptic mite species and their sympa...

Agriculture is one of the largest anthropogenic sources of greenhouse gases (GHGs), with dairy and beef production accounting for nearly two-thirds of emissions. Several recent papers suggest that dung beetles may affect fluxes of GHGs from cattle farming. Here, we put these previous findings into context. Using Finland as an example, we assessed GHG emissions at three scales: the dung pat, pas...

the family of staphylinidae (rove beetles) includes 40000 species and has a world-wide distribution . many species of paederus have been known for a long time as the causative agent of linear dermatitis. paederus beetles are attracted to artificial lights in the evening during the hot and humid summer nights. whenever they are crashed or smeared on the skin they release their toxin called pede...

buprestid beetles are one of the important components of the biodiversity of forest ecosystem in kurdistan province. different characteristics of biodiversity of buprestid beetles were studied by use of window trap, colored pan and colored sticky trap in these forests during 2009 and 2010. a total of 1205 specimens of 44 species were caught by use of considered traps during appearance of adults...

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...

Traps containing a combination floral and synthetic pheromone lure are used to monitor and manage Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae). One key factor limiting trap effectiveness for beetle control is the "trap spillover" phenomenon, in which the trap attracts beetles without capturing them, resulting in increased damage to surrounding host plants. We investigat...
