One species, Calymmaderus funki Pic, is reported as a new country record. Six genera are reported as new records for Peru (i.e. Byrrhodes, Caenocara, Mirosternus, Petalium, and Cryptorama), however, species within these genera are not yet identified. This contribution is part of the ‘Beetles of Peru’ project.AuthorsRachel A. Arango, Caroline S. ChabooSourceJournal: Journal of the Kansas Entomological SocietyYear2016
- Permethrin is a common insecticide used in wood preservation. It is an effective synthetic pyrethroid that is considered to be less toxic to higher organisms than organochlorine insecticides. In wood preservation, it can be used in combination with fungicides such as 3-iodo-2-propynyl butyl carbamate (IPBC). Permethrin has a dual mode of action as it is a repellent and a contact insecticide. Although the efficacy of permethrin on termites has been examined, many of the studies looked at the effects of treated soil and not treated wood. In this study, we examined the effects of three levels...AuthorsMark E. Mankowski, Blossie Boyd, Geoffrey WebbSourceProceedings, American wood protection association annual meeting 2016.

- Crown fire hazard is often quantified using effective canopy bulk density (CBD) and canopy base height (CBH). When CBD and CBH are estimated using nonlocal crown fuel biomass allometries and uniform crown fuel distribution assumptions, as is common practice, values may differ from estimates made using local allometries and nonuniform distributions. We estimated CBD and CBH for mostly pure, even-aged stands of seven conifer species by modifying the Fire and Fuels Extension to the Forest Vegetation Simulator to use nonuniform crown fuel distributions, which allowed us to determine whether...AuthorsSeth A.

- The emerald ash borer (EAB, Agrilus planipennis Fairmaire) has killed hundreds of millions of ash trees since it was discovered near Detroit, Michigan and Windsor, Ontario in 2002 (www.emeraldashborer. info 2016) and continues to spread in North America. Canadian and U.S. federal, provincial, and state regulatory agencies have used artificial traps and lures in surveys to detect new infestations since 2008. Traps used in detection surveys have evolved over the years, and several different trap designs and lures have been tested in research studies.AuthorsTherese M. Poland, Deborah G.

- The integrated effects of the many risk factors associated with West Nile virus (WNV) incidence are complex and notwell understood. We studied an array of risk factors in and around Atlanta, GA, that have been shown to be linked with WNV inother locations. This array was comprehensive and included climate and meteorological metrics, vegetation characteristics, landuse / land cover analyses, and socioeconomic factors. Data on mosquito abundance and WNV mosquito infection rates wereobtained for 58 sites and covered 2009-2011, a period following the combined storm water – sewer overflow...AuthorsGraeme Lockaby, Navideh Noori, Wayde Morse, Wayne C.

- The existing literature suggests that the presence of natural amenities, such as open spaces, can be highly valued and affect economic decisions about where people live and work. This article contributes to previous research by testing this hypothesis using a unique micro-level data set and by examining spatial variations in income levels and housing prices in the presence of natural amenities in a case study of Arizona. Proximity effects are estimated based on a geographic information system road network in which each variable represents the road mile distance from house i to its closest...AuthorsGerman M.

- Heterobasidion root disease (previously called annosum, annosus, or Fomes root disease / root rot) is one of the most economically damaging forest diseases in the Northern Hemisphere. Heterobasidion root disease (HRD) in the southeastern U.S. is caused by the pathogen Heterobasidion irregulare, which infects loblolly, longleaf, pitch, shortleaf, slash, Virginia, and white pine; eastern red cedar; and incense cedar. This disease is predominately found in pine plantations after thinning on sites with well-drained sandy soils.AuthorsTyler J. Dreaden, Jason A.

- Factors that influence fungal communities in ambrosia beetle mycangia are poorly understood. The beetle that is responsible for spreading laurel wilt in SE USA, Xyleborus glabratrus, was examined at three sites along a 500 km N-S transect in Florida, each populated by host trees in the Lauraceae. Fungal phenotypes were quantified in mycangia of individual females that were collected from a site in Miami-Dade County (MDC), 25.8N, with swamp bay (Persea palustris), one in Highlands County (HC), 27.9N, with silkbay (P. humulis) and swamp bay and another in Alachua County (AC), 29.8N, with...AuthorsAlina S.

- In October 2014, a survey for diseases and pests of an emerging fruit crop, avocado (Persea americana) (FAO 2000), was conducted in Southern Shan State of Myanmar (aka Burma). In the Tuanggyi District (1,400 m elevation, 20.5°N 97°E), monocultures of up to 20 ha were observed, whereas in the Ywangan District (1,850 m elevation, 21.2°N 96.4°E), avocado trees were used primarily as shade for the production of coffee (Coffea arabica). In both districts, symptoms of laurel wilt were observed on avocado, but no other tree. Trees exhibited sapwood discoloration, leaf necrosis and defoliation,...AuthorsR. C. Ploetz, Y. Y. Thant, M. A.

- The U. S. Culture Collection Network was formed in 2012 by a group of culture collection scientists and stakeholders in order to continue the progress established previously through efforts of an ad hock group. The network is supported by a Research Coordination Network grant from the U.S. National Science Foundation (NSF) and has the goals of promoting interaction among collections, encouraging the adoption of best practices, and protecting endangered or orphaned collections. After prior meetings to discuss best practices, shared data, and synergy with genome progrrams, the network held a...AuthorsKevin McCluskey, Anne Alvarez, Rick Bennett, Deepak Bokati, Kyria Boundy-Mills, Daniel Brown, Carolee T.
