Detection and Quantification of Leptographium Wageneri, The
1798 Detection and quantification of Leptographium wageneri, the cause of black-stain root disease, from bark beetles (Coleoptera: Scolytidae) in Northern California using regular and real-time PCR Wolfgang Schweigkofler, William J. Otrosina, Sheri L. Smith, Daniel R. Cluck, Kevin Maeda, Kabir G. Peay, and Matteo Garbelotto Abstract: Black-stain root disease is a threat to conifer forests in western North America. The disease is caused by the ophiostomatoid fungus Leptographium wageneri (W.B. Kendr.) M.J. Wingf., which is associated with a number of bark beetle (Coleoptera: Scolytidae) and weevil species (Coleoptera: Curculionidae). We developed a polymerase chain reac- tion test to identify and quantify fungal DNA directly from insects. Leptographium wageneri DNA was detected on 142 of 384 bark beetle samples (37%) collected in Lassen National Forest, in northeastern California, during the years 2001 and 2002. Hylastes macer (LeConte) was the bark beetle species from which Leptographium DNA was amplified most regularly (2001: 63.4%, 2002: 75.0% of samples). Lower insect–fungus association rates were found for Hylurgops porosus (LeConte), Hylurgops subcostulatus (Mannerheim), Hylastes gracilis (LeConte), Hylastes longicollis (Swaine), Dendroctonus valens (LeConte), and Ips pini (Say). The spore load per beetle ranged from 0 to over1×105 spores, with only a few beetles carrying more than1×103 spores. The technique permits the processing of a large number of samples synchronously, as required for epidemiological studies, to study infection rates in bark beetle populations and to identify potential insect vectors.

The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

A Faunal Survey of the Elateroidea of Montana by Catherine Elaine
A faunal survey of the elateroidea of Montana by Catherine Elaine Seibert A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology Montana State University © Copyright by Catherine Elaine Seibert (1993) Abstract: The beetle family Elateridae is a large and taxonomically difficult group of insects that includes many economically important species of cultivated crops. Elaterid larvae, or wireworms, have a history of damaging small grains in Montana. Although chemical seed treatments have controlled wireworm damage since the early 1950's, it is- highly probable that their availability will become limited, if not completely unavailable, in the near future. In that event, information about Montana's elaterid fauna, particularity which species are present and where, will be necessary for renewed research efforts directed at wireworm management. A faunal survey of the superfamily Elateroidea, including the Elateridae and three closely related families, was undertaken to determine the species composition and distribution in Montana. Because elateroid larvae are difficult to collect and identify, the survey concentrated exclusively on adult beetles. This effort involved both the collection of Montana elateroids from the field and extensive borrowing of the same from museum sources. Results from the survey identified one artematopid, 152 elaterid, six throscid, and seven eucnemid species from Montana. County distributions for each species were mapped. In addition, dichotomous keys, and taxonomic and biological information, were compiled for various taxa. Species of potential economic importance were also noted, along with their host plants. Although the knowledge of the superfamily' has been improved significantly, it is not complete. -

Department The University of British Columbia Vancouver, Canada DE-6 (2/88) Abstract Increasing forest management resulting from bark beetle attack in British Columbia's forests has created a need to assess the impact of single species management on local insect biodiversity. In the Fort St James Forest District, in central British Columbia, Douglas-fir (Pseudotsuga menziesii Franco) (Fd) grows at the northern limit of its North American range. At the district level the species is rare (representing 1% of timber stands), and in the early 1990's growing populations of the Douglas-fir beetle (Dendroctonus pseudotsuage Hopkins) threatened the loss of all mature Douglas-fir habitat in the district. -

(type species Tyrannothroscus rex n.sp.) and Pseudothroscus n. gen. (type species Pseudothroscus balticus n. sp.). Four species are described from Baltic amber: Tyrannothroscus rex n. sp., Pseudothroscus balticus n. sp., Potergus superbus n. sp. and Trixagus parvulus n. sp. Pactopus burmensis n. sp. is described from Burmese amber. A phylogenetic analysis of the known throscid genera is performed. Aulonothroscus Horn and Trixagus Kugelann are shown to be sister-groups, the sister-group of this clade is the genus Pactopus Horn and the sister group of these three genera is the genus Potergus Bonvouloir. The oldest previ- ously known throscids were species belonging to the genera Rhomboaspis Kirejtshuk & Kovalev and Potergosoma Kire- jtshuk & Kovalev, both from Lebanese Amber, 125–135 Mya. The present analysis shows that the extinct Baltic amber genera Jaira Muona and Pseudothroscus belong to clades at least as old as the Lebanese fossils. The Burmese amber fossil Pactopus burmensis, 99 Mya, is considerably older than any of the previously known species belonging to the four extant genera: Pactopus, Potergus, Aulonothroscus or Trixagus. -

Biodiversity of Coleoptera and the Importance of Habitat Structural Features in a Sierra Nevada Mixed-Conifer Forest
COMMUNITY AND ECOSYSTEM ECOLOGY Biodiversity of Coleoptera and the Importance of Habitat Structural Features in a Sierra Nevada Mixed-conifer Forest 1 2 KYLE O. APIGIAN, DONALD L. DAHLSTEN, AND SCOTT L. STEPHENS Department of Environmental Science, Policy, and Management, 137 Mulford Hall, University of California, Berkeley, CA 94720Ð3114 Environ. Entomol. 35(4): 964Ð975 (2006) ABSTRACT Beetle biodiversity, particularly of leaf litter fauna, in the Sierran mixed-conifer eco- system is poorly understood. This is a critical gap in our knowledge of this important group in one of the most heavily managed forest ecosystems in California. We used pitfall trapping to sample the litter beetles in a forest with a history of diverse management. We identiÞed 287 species of beetles from our samples. Rarefaction curves and nonparametric richness extrapolations indicated that, despite intensive sampling, we undersampled total beetle richness by 32Ð63 species. We calculated alpha and beta diversity at two scales within our study area and found high heterogeneity between beetle assemblages at small spatial scales. A nonmetric multidimensional scaling ordination revealed a community that was not predictably structured and that showed only weak correlations with our measured habitat variables. These data show that Sierran mixed conifer forests harbor a diverse litter beetle fauna that is heterogeneous across small spatial scales. Managers should consider the impacts that forestry practices may have on this diverse leaf litter fauna and carefully consider results from experimental studies before applying stand-level treatments. KEY WORDS Coleoptera, pitfall trapping, leaf litter beetles, Sierra Nevada The maintenance of high biodiversity is a goal shared Sierras is available for timber harvesting, whereas only by many conservationists and managers, either be- 8% is formally designated for conservation (Davis cause of the increased productivity and ecosystem and Stoms 1996). -
