Abstract Weevil species of Cryptorhynchinae from Guatemala are among the richest groups of Curculionidae and are highly diverse in the tropics. In the present study, a taxonomic review of the Cryptorhynchinae species of Zacapa was carried out in the different plant associations that are distributed in the altitudinal gradient in order to record the diversity of species in this group. The objectives of the present study were: 1) To record the diversity of genera and species of Cryptorhynchinae from the department of Zacapa, 2) To determine the associations of the species of Cryptorhynchinae with the floristic assemblages of the department of Zacapa, 3) To describe unknown species of Cryptorhynchinae from the department of Zacapa and 4) To reduce the taxonomic impediment of the genus and species of Cryptorhynchinae de Zacapa. To achieve the proposed objectives, weevil collections were done with a beating blanket, litter sifters and manual collection, all specimens were kept in 95% ethanol. Among the most important results, the record of 18 genera of Cryptorhynchinae stands out, of which four have not been described and two species of Gerstaeckeria that have not been described either. In addition, a list of Cryptorhynchinae species from Guatemala, a list of Cryptorhynchinae genera from Zacapa, and a dichotomous key for identification of Cryptorhynchinae genera from Guatemala are provided. All the information associated with the project specimens was loaded to the Guatemala biodiversity portal platform (https://serv.biokic.asu.edu/guatemala/portal/). 4.

Arthropod samples were collected April to October in 2003 and 2004. We collected 233 weevils representing 11 species from 9 genera. CuwIio and Cyrtepistomus species predominated; Gono~chelusspecies were notable. Our preliminary data indicates that acorn weevil emergence may not be reduced following a stngle spring fire.

    Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation.

Twenty-three species documented from the parkway are first records for the state. Of the nine capture methods used during the survey, Malaise traps were the most successful. Periods of adult activity, based on dates of capture, are given for each species. Relative abundance is noted for each species based on the number of captures. Sixteen species adventive to North America are documented from the parkway, including three species documented for the first time in the state. Range extensions are documented for two species. Images of five species new to Virginia are provided. Keywords: beetles, biodiversity, Malaise traps, national parks, new state records, Potomac Gorge. INTRODUCTION This study provides a preliminary list of the weevils of the superfamily Curculionoidea within the George Washington Memorial Parkway (GWMP) national park site in northern Virginia.

  • Section IV – Guideline for the Texas Priority Species List
    Section IV – Guideline for the Texas Priority Species List Associated Tables The Texas Priority Species List……………..733 Introduction For many years the management and conservation of wildlife species has focused on the individual animal or population of interest. Many times, directing research and conservation plans toward individual species also benefits incidental species; sometimes entire ecosystems. Unfortunately, there are times when highly focused research and conservation of particular species can also harm peripheral species and their habitats. Management that is focused on entire habitats or communities would decrease the possibility of harming those incidental species or their habitats. A holistic management approach would potentially allow species within a community to take care of themselves (Savory 1988); however, the study of particular species of concern is still necessary due to the smaller scale at which individuals are studied. Until we understand all of the parts that make up the whole can we then focus more on the habitat management approach to conservation. Species Conservation In terms of species diversity, Texas is considered the second most diverse state in the Union. Texas has the highest number of bird and reptile taxon and is second in number of plants and mammals in the United States (NatureServe 2002). There have been over 600 species of bird that have been identified within the borders of Texas and 184 known species of mammal, including marine species that inhabit Texas’ coastal waters (Schmidly 2004). It is estimated that approximately 29,000 species of insect in Texas take up residence in every conceivable habitat, including rocky outcroppings, pitcher plant bogs, and on individual species of plants (Riley in publication).

Species status assessment of Tobusch Fishhook Cactus (Sclerocactus brevihamatus ssp. tobuschii (W.T. Marshall) N.P. Taylor). U.S. Fish and Wildlife Service Southwest Region, Albuquerque, New Mexico. 65 pp. + 2 appendices. i Tobusch Fishhook Cactus Species Status Assessment - Final EXECUTIVE SUMMARY Tobusch fishhook cactus is a small cactus, with curved “fishhook” spines, that is endemic to the Edwards Plateau of Texas. It was federally listed as endangered on November 7, 1979 (44 FR 64736) as Ancistrocactus tobuschii. At that time, fewer than 200 individuals had been documented from 4 sites. Tobusch fishhook cactus is now confirmed in 8 central Texas counties: Bandera, Edwards, Kerr, Kimble, Kinney, Real, Uvalde, and Val Verde. In recent years, over 4,000 individuals have been documented in surveys and monitoring plots. Recent phylogenetic evidence supports classifying Tobusch fishhook cactus as Sclerocactus brevihamatus ssp. tobuschii. It is distinguished morphologically from its closest relative, S. brevihamatus ssp. brevihamatus, on the basis of yellow versus pink- or brown-tinged flowers, fewer radial spines, and fewer ribs. Additionally, subspecies tobuschii is endemic to limestone outcrops of the Edwards Plateau, while subspecies brevihamatus occurs in alluvial soils in the Tamaulipan Shrublands and Chihuahuan Desert. A recent investigation found genetic divergence between the two subspecies, although they may interact genetically in a narrow area where their ranges overlap.
