Root Weevils Ryan Davis Arthropod Diagnostician
Published by Utah State University Extension and Utah Plant Pest Diagnostic Laboratory ENT-193-18 May 2018 Root Weevils Ryan Davis Arthropod Diagnostician Quick Facts • Root weevils are a group of small, black-to-brown weevils that commonly damage ornamental and small fruit plants in Utah. • Adult root weevil damage is characterized by marginal leaf notching and occasional feeding on buds and young shoots. • Larval root weevil damage occurs below ground; damage to roots can lead to canopy decline or plant death. • Root weevils are occasional nuisance pests in homes and structures mid-summer through fall. • Manage root weevil larvae by applying a systemic insecticide to the soil around host plants April through September. • Adults feeding on the above-ground portion of plants can be targeted with pyrethroid pesticides Black vine weevil adult (Kent Loeffler, Cornell University, Bugwood.org) starting in late June or early July. IDENTIFICATION INTRODUCTION Root weevils are small beetles ranging in length from about 1/4 to 1/3 inch depending on The black vine weevil (Otiorhynchus sulcatus), species. Coloration is variable, but the commonly lilac root weevil (O. meridionalis) strawberry weevil encountered species in Utah are black with gold (O. ovatus) and rough strawberry root weevil (O. flecks (black vine weevil) or solid brown to black, rugosostriatus) are a complex of non-native, snout- shiny or matte. As a member of the weevil family nosed beetles (Coleoptera: Curculionidae) that (Curculionidae), these pests have a snout, but it cause damage to ornamentals and small fruit crops is shortened and rectangular compared to other in Utah. Root weevils are occasional nuisance pests weevils that have long, skinny mouthparts. -

Bandung 40391, Indonesia c Indonesian Center for Horticulture Research and Development, Jl. Raya Ragunan Pasar Minggu - Jakarta Selatan 12540, Indonesia Email: [email protected] Introduction General basis and protocol for classical biological control Biological control is defined as "the action of parasites (parasitoids), predators or pathogens in Maintaining another organism's population density at a lower average than would occur in their absence" (Debach 1964). Thus, biological control represents the combined effects of a natural enemy complex in suppressing pest populations. The concept of biological control arose from the observed differences in abundance of many animals and plants in their native range compared to areas in which they had been introduced in the absence of (co-evolved) natural enemies. As such, populations of introduced pests, unregulated by their natural enemies may freely multiply and rise to much higher levels than previously observed. Biological control is a component of natural control which describes environmental checks on pest buildup (Debach 1964). In agriculture, both the environment (i.e. farming systems) and natural enemies may be manipulated in an attempt to reduce pest pressure. Classical biological control concerns the search for natural enemies in a pest's area of origin, followed by quarantine and importation into locations where the pest has been introduced. -

Twenty-seven species are found in the Paleocene, 442 in the Eocene and 94 in the Oligocene. The greatest diversity of Curculionoidea is described from the Eocene of Europe and North America. The richest faunas are known from Eocene localities, Florissant (177 species), Baltic amber (124 species) and Green River formation (75 species). The family Curculionidae dominates in all Paleogene localities. Weevil species associated with herbaceous vegetation are present in most localities since the middle Paleocene. A list of Curculionoidea species and their distribution by location is presented. Keywords: Coleoptera; Curculionoidea; fossil weevil; faunal structure; Paleocene; Eocene; Oligocene 1. Introduction Research into the biodiversity of the past is very important for understanding the development of life on our planet. Insects are one of the Main components of both extinct and recent ecosystems. Coleoptera occupied a special place in the terrestrial animal biotas of the Mesozoic and Cenozoics, as they are characterized by not only great diversity but also by their ecological specialization. -

Of the Galapagos Islands, Ecuador
Belgian Journal ofEntomology 5 (2003) : 89-102 A review of the Oedemeridae (Coleoptera) of the Galapagos Islands, Ecuador Stewart B. PECK and Joyce COOK Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, K1S 5B6, Canada (e-mail: ste'[email protected]). Abstract Extensive new collections contribute new information on the identity and distribution of the oedemerid beetles of the Galiipagos Islands. Specimens previously recorded as near Oxacis pilosa CHAMPION are descn'bed as Oxycopis galapagoensis sp. n. Oxacis pilosa CHAMPION of Guatemala and Nicaragua is transferred to the genus Oxycopis. Hypasclera collenettei (BLAIR) is the most common and widespread species in the islands, and is variable in that it shows significant differences in aedeagus morphology between separate islands. Alloxacis hoodi V AN DYKE is found be a synonym of H. collenettei. H. seymourensis (MUTCHLER) is known only from the central islands. Paroxacis galapagoensis (LINELL) is also widespread. All four Galapagos species are presently considered to be endemic, and each represents a separate ancestral colonization of the archipelago. Keywords: · Hypasclera, Oxycopis, Paroxacis, island insects, endemic species, colonization. Introduction Members of the beetle family Oedemeridae are commonly called the false blister beetles. Adults are found frequently at lights or by sweeping vegetation, and they are obligate pollen feeders (AR.NETT, 1984). Larvae may feed on plant roots or may be inhabitants of moist decaying wood and some may live in salt-soaked driftwood (ARNETT, 1984, KrusKA, 2002). Oedemerids have been described and reported from the Galapagos by several workers: BLAIR (1928; 1933); F'RANZ (1985); LINELL (1898); MUTCHLER (1938); and VAN DYKE (1953). -

Oise amber has eight species, Baltic amber has 118 species, and Rovno amber has 16 species. Nine new genera and 18 new species are described from Baltic amber. Four new synonyms are noted: Palaeometrioxena Legalov, 2012, syn. nov. is synonymous with Archimetrioxena Voss, 1953; Paleopissodes weigangae Ulke, 1947, syn. nov. is synonymous with Electrotribus theryi Hustache, 1942; Electrotribus erectosquamata Rheinheimer, 2007, syn. nov. is synonymous with Succinostyphlus mroczkowskii Kuska, 1996; Protonaupactus Zherikhin, 1971, syn. nov. is synonymous with Paonaupactus Voss, 1953. Keys for Eocene amber Curculionoidea are given. There are the first records of Aedemonini and Camarotini, and genera Limalophus and Cenocephalus in Baltic amber. Keywords: Coleoptera; Curculionoidea; fossil weevil; new taxa; keys; Palaeogene 1. Introduction The Curculionoidea are one of the largest and most diverse groups of beetles, including more than 62,000 species [1] comprising 11 families [2,3]. They have a complex morphological structure [2–7], ecological confinement, and diverse trophic links [1], which makes them a convenient group for characterizing modern and fossil biocenoses. -

Insect Classification Standards 2020
RECOMMENDED INSECT CLASSIFICATION FOR UGA ENTOMOLOGY CLASSES (2020) In an effort to standardize the hexapod classification systems being taught to our students by our faculty in multiple courses across three UGA campuses, I recommend that the Entomology Department adopts the basic system presented in the following textbook: Triplehorn, C.A. and N.F. Johnson. 2005. Borror and DeLong’s Introduction to the Study of Insects. 7th ed. Thomson Brooks/Cole, Belmont CA, 864 pp. This book was chosen for a variety of reasons. It is widely used in the U.S. as the textbook for Insect Taxonomy classes, including our class at UGA. It focuses on North American taxa. The authors were cautious, presenting changes only after they have been widely accepted by the taxonomic community. Below is an annotated summary of the T&J (2005) classification. Some of the more familiar taxa above the ordinal level are given in caps. Some of the more important and familiar suborders and families are indented and listed beneath each order. Note that this is neither an exhaustive nor representative list of suborders and families. It was provided simply to clarify which taxa are impacted by some of more important classification changes. Please consult T&J (2005) for information about taxa that are not listed below. Unfortunately, T&J (2005) is now badly outdated with respect to some significant classification changes. Therefore, in the classification standard provided below, some well corroborated and broadly accepted updates have been made to their classification scheme. Feel free to contact me if you have any questions about this classification. -
Temporal Lags and Overlap in the Diversification of Weevils and Flowering Plants
Temporal lags and overlap in the diversification of weevils and flowering plants Duane D. McKennaa,1, Andrea S. Sequeirab, Adriana E. Marvaldic, and Brian D. Farrella aDepartment of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA 02138; bDepartment of Biological Sciences, Wellesley College, Wellesley, MA 02481; and cInstituto Argentino de Investigaciones de Zonas Aridas, Consejo Nacional de Investigaciones Científicas y Te´cnicas, C.C. 507, 5500 Mendoza, Argentina Edited by May R. Berenbaum, University of Illinois at Urbana-Champaign, Urbana, IL, and approved March 3, 2009 (received for review October 22, 2008) The extraordinary diversity of herbivorous beetles is usually at- tributed to coevolution with angiosperms. However, the degree and nature of contemporaneity in beetle and angiosperm diversi- fication remain unclear. Here we present a large-scale molecular phylogeny for weevils (herbivorous beetles in the superfamily Curculionoidea), one of the most diverse lineages of insects, based on Ϸ8 kilobases of DNA sequence data from a worldwide sample including all families and subfamilies. Estimated divergence times derived from the combined molecular and fossil data indicate diversification into most families occurred on gymnosperms in the Jurassic, beginning Ϸ166 Ma. Subsequent colonization of early crown-group angiosperms occurred during the Early Cretaceous, but this alone evidently did not lead to an immediate and ma- jor diversification event in weevils. Comparative trends in weevil diversification and angiosperm dominance reveal that massive EVOLUTION diversification began in the mid-Cretaceous (ca. 112.0 to 93.5 Ma), when angiosperms first rose to widespread floristic dominance. These and other evidence suggest a deep and complex history of coevolution between weevils and angiosperms, including codiver- sification, resource tracking, and sequential evolution.
