U.S. Fish and Wildlife Service U.S. Department of the Interior National Wildlife Refuge System National Protocol Framework for the Inventory and Monitoring of Bees SAM DROEGE JOSEPH ENGLER ELIZABETH SELLERS LEE O’BRIEN ON THE COVER Bumble bee (Bombus sp.) foraging on purple cone flower (Echinacea purpurea) Photograph by: Ryan Hagerty NWRS Survey Protocol Signature Page 1 Version is a decimal number with the number left of decimal place indicating the number of times this protocol has been approved (e.g., first approved version is 1.0.; prior to first approval all versions are 0.x; after first approval, all minor changes are indicated as version 1. x until the second approval and signature, which establishes version 2.0, and so on). 4 Signature by Regional I&M Coordinator signifies approval of a protocol framework to be used at multiple USFWS stations within a Region. 5 Signature by National I&M Coordinator signifies approval of a protocol used at multiple USFWS stations from two or more Regions. i Survey Protocol Summary This national protocol framework is a standardized tool for the inventory and monitoring of the approximately 4,200 species of native and non-native bee species that may be found within the National Wildlife Refuge System (NWRS) administered by the U.S. Fish and Wildlife Service (USFWS). However, this protocol framework may also be used by other organizations and individuals to monitor bees in any given habitat or location. Our goal is to provide USFWS stations within the NWRS (NWRS stations are land units managed by the USFWS such as national wildlife refuges, national fish hatcheries, wetland management districts, conservation areas, leased lands, etc.) with techniques for developing an initial baseline inventory of what bee species are present on their lands and to provide an inexpensive, simple technique for monitoring bees continuously and for monitoring and evaluating long-term population trends and management impacts. The latter long-term monitoring technique requires a minimal time burden for the individual station, yet can provide a good statistical sample of changing populations that can be investigated at the station, regional, and national levels within the USFWS’ jurisdiction, and compared to other sites within the United States and Canada. This protocol framework was developed in cooperation with the United States Geological Survey (USGS), the USFWS, and a worldwide network of bee researchers who have investigated the techniques and methods for capturing bees and tracking population changes. The protocol framework evolved from field and lab-based investigations at the USGS Bee Inventory and Monitoring Laboratory at the Patuxent Wildlife Research Center in Beltsville, Maryland starting in 2002 and was refined by a large number of USFWS, academic, and state groups. It includes a Protocol Introduction and a set of 8 Standard Operating Procedures or SOPs and adheres to national standards of protocol content and organization. The Protocol Narrative describes the history and need for the protocol framework and summarizes the basic elements of objectives, sampling design, field methods, training, data management, analysis, and reporting. The SOPs provide more detail and specific instructions for implementing the protocol framework. A central database, for managing all the resulting data is under development. We welcome use of this protocol framework by our partners, as appropriate for their bee inventory and monitoring objectives. Suggested citation: Droege, S, JD Engler, E Sellers and LE O’Brien. 2016.

    Novel Detection and Removal of Hazardous Biocide Residues Historically Applied to Herbaria

    AMGUEDDFA CYMRU - NATIONAL MUSEUM WALES Department of Natural Sciences Novel detection and removal of hazardous biocide residues historically applied to herbaria Dr. Victoria J. Purewal ACR1 & Prof. Belinda J. Colston2 IDENTIFICATION OF HISTORIC TREATMENTS This PhD research was prompted through rising health concerns associated with key members of staff and researchers working on the NMW herbarium. Similar medical conditions including rhinitis, hay fever, loss of sense of smell, dry eyes, dry throat and eczema had developed over a period of just 4 months for some individuals and up to five years in others. Research was undertaken to determine the inorganic and organic biocide contamination on the collections of both lower plant and vascular material. Analysis determined that significant concentrations of naphthalene and mercury, were present on the collections. Literature searches provided confirmation that these chemicals could induce the observed symptoms amongst personnel. Due to the paucity of historic information regarding the treatments applied and the lack of observable signs, this problem has been largely ignored and has therefore become exacerbated. Numerous experiments were attempted to provide a method of identification for historic treatments, and finally scanning with a UV lamp (fig. 1) provided a positive response. UV-A radiation caused a fluorescence on the sheets that was not observable in visible light. The fluorescence induced was distinctly coloured, ranging from cream through to orange. Within these coloured areas, mercury was always present, however no other single chemical provided this response. ANALYSIS Particle Induced X-ray Emission (PIXE) was employed to measure the metal ion concentration within the fluorescence. This process was also able to map an area of the mount sheet.

    467 On the Genera of Anobiidae and Ptinidae Found in Hawaii (Coleoptera) BY ELWOOD C. ZIMMERMAN Bernice P. Bishop Museum (Presented at the meeting of January 5, 1939) The family Ptinidae is represented in Hawaii by only three wide spread, introduced species included in three genera. The islands have, however, a well-developed and comparatively large anobiid fauna. There have been 141 species and 19 varieties recorded, but new species are in local collections. This number of species is more than half as large as the total number (about 250) listed from America north of Mexico. Characteristically, however, as is true of many other Hawaiian groups, the endemic species belong to only a few large genera. Only three genera, two of them endemic, con tain endemic Hawaiian Anobiidae. These three genera have an average of 52 species per genus. The genus containing the largest number of species in Hawaii has 70; the largest in North America has 65. The following tabulation will show at a glance the developments of the Ptinidae and Anobiidae in Hawaii: PTINIDAE Gibbium: one introduced species. Mezium: one introduced species. Ptinus: one introduced species. ANOBIIDAE Catorama: one introduced species. Stegobium: one introduced species. • Holcobius (endemic) : 14 species and 2 varieties endemic. Xyletobius (endemic) : 53 species and 16 varieties endemic. Lasioderma: one introduced species. Mirosternus: 70 species and 1 variety endemic. The families may be separated as follows : Antennae inserted below eyes on front of head and very close together; sides of prothorax not margined Ptinidae Antennae inserted toward sides of head below eyes and widely separated; pro thorax with a conspicuous lateral margin Anobiidae PTINIDAE Key to the Genera found in Hawaii 1.

    Beetles (Coleoptera) of Peru: a Survey of the Families

    JOURNAL OF THE KANSAS ENTOMOLOGICAL SOCIETY 89(3), 2016, pp. 249–252 Beetles (Coleoptera) of Peru: A Survey of the Families. Ptinidae Latreille, 1802 RACHEL A. ARANGO1,3 AND CAROLINE S. CHABOO2 ABSTRACT: A checklist of the ptinid beetles (including Anobiidae) of Peru is presented with 5 subfamilies, 22 genera, and 33 identified species. 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,andCryptorama), however, species within these genera are not yet identified. This contribution is part of the ‘Beetles of Peru’ project. KEY WORDS: Death-watch beetles, spider beetles, powderpost beetles, biodiversity, checklist Diversity in Peru: 5 subfamilies, 22 genera, 33 species. Nomenclature: The family name Ptinidae Latreille (1802: 112) is used here as it has priority over the name Anobiidae Fleming (1821: 50) if the family includes the spider beetles (Subfamily Ptininae Latreille, 1802; Lawrence and Newton 1995). Recognition: Identification of these beetles, commonly referred to as the death-watch and spider beetles, is difficult not only because of their small size and compact body structure, but also due to the highly variable morphology seen within the group. Body structure ranges from rotund and strongly compact to narrow and elongate. Despite this variation, members of this family can generally be recognized by the hood-like pronotum which strongly conceals the head from above, insertion of the antennae just before the eyes, and in many cases, highly contractile appendages that are retained within grooves along the ventral surface. Other characteristics that will aid in identification of members of this family include the antennae with having the apical three segments elongate or broadened or antennae serrate, pectinate, or filiform; trochanters on the metathoracic leg cylindrical and squarely attached to the femora; and five segmented tarsi.

Only seven species of ptinid beetles (Coleoptera: Bostrichoidea: Ptinidae) from the Socotra Island archipelago were known till 2012. Five of them are from the main island of Socotra: Dignomus mesopotamicus (Pic, 1894), Mezium errinaceus Bellés, 2009, Ptinus bertranpetiti Bellés, 2012, Silisoptinus inermicollis Bellés, 2005, and Sphaericus hirsutus Bellés, 2009; two from smaller islands nearby: Clada (Clada) forbesii (Gahan, 1903) and C. (C.) pohli Toskina, 2004. Twelve new species from Socotra Island are recorded here, including members of 2 new genera: Metholbium fulvum gen. nov., sp. nov., and Metholbium pseudofulvum sp. nov. (Anobiinae), Stagetus bezdeki sp. nov., S. farkaci sp. nov., S. hajeki sp. nov., S. krali sp. nov. (Dorcatominae), Clada (Clada) mariae sp. nov., C. (C.) stastnybejceki sp. nov. (Eucradinae), Mesothes socotrensis sp. nov., Rhamna socotrana sp. nov. (both Mesocoelopodinae), Dermolasia pectinicornis gen. nov., sp. nov., Lasioderma karlae sp. nov. (both Xyletininae). Five species previously reported only from neighbouring countries were found there as follows: Synanobium (Synanobium) angustissimus (Pic, 1903), S. (S.) parmatum (Baudi di Selve, 1874), Calymmaderus (Calymmaderus) rufescens (Pic, 1902) (all Dorcatominae), Clada (Clada) pohli Toskina, 2004 (Eucradinae), and Mesocoelopus ingibbosus Pic, 1924 (Mesocoelopodinae).

These profiles are intended for the use of interested laypersons with some knowledge of biology as well as academic audiences. Introduction There are over 1000 described species of anobiids. Many are wood borers but two, the cigarette beetle, Lasioderma serricorne (F.), also known as the tobacco beetle, and the drugstore beetle, Stegobium paniceum (L.) are pests of stored products. Stored-product pests are responsible for tremendous damage and economic losses to post-harvest and stored grains and seeds, packaged food products, and animal and plant derived items and commodities. Besides causing direct damage by their feeding, they also elicit Figure 1. Adult cigarette beetle, Lasioderma serricorne (F.). disgust, annoyance, and anger in those who find them Credits: L.J.

    Sarhad J. Agric. Vol.24, No.2, 2008 FOOD PREFERENCES OF LASIODERMA SERRICORNE (F.) (COLEOPTERA: ANOBIIDAE) ON FOUR TYPES OF TOBACCO Muhammad Saeed*, Said Mir Khan* and Muhammad Shahid** ABSTRACT Flue-cured Virginia (FCV), Sun-cured Rustica (SCR), Dark Air-cured (DAC) and Air-cured Burley (ACB) were evaluated for preference by the 4 th instar larvae and adult stages of Lasioderma serricorne (Fabricius) (Coleoptera: Anobiidae). Nicotine, reducing sugars and starch contents were determined and the impact of chemical factors on preference was worked out. FCV tobacco was preferred by both larval and adult stages with 2.18 and 1.49 beetles, respectively followed by SCR with 1.58 larvae and 1.25 adults. ACB was preferred by minimum number of larvae (0.64) and adults (0.82). Nicotine content was high (4.09%) in SCR, while low (1.42%) in DAC. Maximum reducing sugars (14.27%) and starch (6.89%) was recorded in FCV, while minimum (0.55%) reducing sugars and (1.14%) starch documented for ACB. Significant positive interaction among the larval and adult stages of L. serricorne with reducing sugars and starch revealed that FCV was highly preferred by larval and adult stages due to high contents of reducing sugars and starch, while ACB was least preferred due to low contents of reducing sugars and starch. Nicotine had non-significantly negative effect on the preference of both larvae and adults. Key words: Lasioderma serricorne, Preference, Tobacco Types, Feeding. INTRODUCTION Cigarette beetle, Lasioderma serricorne (Fabricius) completes its life cycle earlier i.e., in 50 days, while (Coleoptera: Anobiidae) is a serious pest of stored in tobacco with high nicotine and very small amounts tobacco (Gopalachari, 1984), and is known to infest of total sugars and starch, the development is very and consume all stages of the product, resulting in slow and the beetle completes its life cycle in a range spoilage of at least 1% (US$300 million) of stored of 65 to 80 days.

Received: 4 September 2020; Accepted: 12 October 2020; Published: 13 October 2020 Simple Summary: Insect hosts have close relationships with microbial symbionts. The limited metabolic networks of most insects are enhanced by these symbiotic relationships. Using symbiotic microorganisms for biological control of insects and insect-borne diseases has become an important research topic and shows potential for the development of applicable control approaches. Blattella germanica (L.) is public health pest worldwide; it is difficult to control because of its strong reproductive ability, adaptability, and resistance to insecticides. In this paper, the diverse biological functions (nutrition metabolism, reproductive regulation, insecticide resistance, defense, and behavior management) of symbionts, their interaction mechanism with hosts, and the research progress in the control of B. germanica are reviewed and discussed. Abstract: Insects have close symbiotic relationships with several microbes, which extends the limited metabolic networks of most insects. Using symbiotic microorganisms for the biological control of pests and insect-borne diseases has become a promising direction. Blattella germanica (L.) (Blattaria: Blattidae) is a public health pest worldwide, which is difficult to control because of its strong reproductive ability, adaptability, and resistance to insecticides.
