Diversity, Abundance And Seasonality Of Ambrosia Beetles (Coleoptera: Curculionidae) In Southern Mississippi, C. T. Werle, B. J. Sampson, J. B. Oliver

Midsouth Entomologist

A survey was undertaken in 2010 to assess the composition of the ambrosia beetle (Coleoptera: Curculionidae: Scolytinae) community at two research sites in southern Mississippi. Inexpensive beetle traps were constructed and fitted with ethanol lures, and bi-weekly collections were made from March through November. The granulate ambrosia beetle [Xylosandrus crassiusculus (Motschulsky)] was the most abundant xyleborine species at both sites, with more specimens collected at the Poplarville site. Other species were more abundant at the McNeill site. The black twig borer [Xylosandrus compactus (Eichhoff)] was the second-most abundant species in Mississippi, yet has not been reported from collections by collaborators …

Midsouth Entomologist

Survey-based soybean insect losses provide a glimpse of current soybean management practices and allow one to see evolving trends. This survey was initiated in Mississippi in 2004, Tennessee in 2008, and Arkansas in 2009. The 2011 survey is the first to include Alabama, Louisiana, North Carolina, and Virginia. The 2011 survey represents nearly 9.5 million acres across the southern U.S. Overall, the 2011 survey shows corn earworm to be responsible for more than 50% of all insect-related costs and losses in the surveyed states. More than 50% of the acreage was scouted for a fee and more than 50% of …

Western Striped And Western Spotted Cucumber Beetles, Diane Alston, Dennis Worwood

All Current Publications

Cucumber beetles (Coleoptera: Chrysomelidae) are pests of cucurbits throughout the U.S. Western species of cucumber beetles will also feed on leaves of other vegetables (especially corn, tomato, potato, and bean) and soft fruits (especially apricot and peach) (Table 1). In Utah, watermelon and cantaloupe have been the main commercial crops attacked. In home gardens, zucchini, cucumber and cantaloupe have suffered the most damage.

Los Ciempiés Escutigeromorfos (Scutigeromorpha), Escolopendromorfos (Scolopendromorpha) Y Geofilomorfos (Geophilomorpha) De La Selva Tropical Caducifolia De La Reserva De Chamela, Jalisco, México, Fabio Germán Cupul-Magaña

Insecta Mundi

The Chamela-Cuixmala Biosphere Reserve is located on the Pacific coast of the state of Jalisco in Mexico. The Reserve was founded in 1993 and covers 13142 hectares. It is one of the few reserves in Mexico created for the protection of the tropical deciduous (dry) forest and associated ecosystems. Five centipede species have hitherto been reported from the Reserve: Cormocephalus impressus Porat, 1876; Dendrothereua linceci (Wood, 1867); Ectonocryptoides quadrimeropus Shelley and Mercurio, 2005; Scolopendra polymorpha (Wood, 1861) and Scolopendra viridis Say, 1821. The first formal study on the centipede fauna in the Reserve commenced in July 2010. After one year …

Preliminary Checklist Of The Cerambycidae, Disteniidae, And Vesperidae (Coleoptera) Of Peru, Miguel A. Monné, Eugenio H. Nearns, Sarah C. Carbonel Carril, Ian P. Swift, Marcela L. Monné

Insecta Mundi

A preliminary checklist of the Cerambycidae, Disteniidae, and Vesperidae (Coleoptera) of Peru is presented. Within Cerambycidae, we record five subfamilies, 55 tribes, 345 genera and subgenera, and 714 species. Within Disteniidae, we record one tribe, six genera, and 11 species. We also record one subfamily, one tribe, one genus, and two species within Vesperidae. Four new country records are recorded: one species in the tribe Anacolini (Cerambycidae: Prioninae): Cycloprionus flavus Tippmann, 1953; and three species in the tribe Onciderini (Cerambycidae: Lamiinae): Cacostola simplex (Pascoe, 1859); Marensis simplex (Bates, 1865); Trachysomus cavigibba Martins, 1975. In addition, 161 species recorded are known …

A Summary Of The Endemic Beetle Genera Of The West Indies (Insecta: Coleoptera); Bioindicators Of The Evolutionary Richness Of This Neotropical Archipelago, Stewart B. Peck, Daniel E. Perez-Gelabert

Insecta Mundi

The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates. This paper presents data on genus level endemicity for the most speciose (but less well publicised) group of terrestrial animals: the beetles, with 205 genera (in 25 families) now recognized as being endemic (restricted) to the West Indies. The predominant families with endemic genera are Cerambycidae (41), Chrysomelidae (28), Curculionidae (26), and Staphylinidae (25). This high level of beetle generic endemicity can be extrapolated to …

Chalcosicya Maya N. Sp, A New Mexican Species (Coleoptera: Chrysomelidae: Eumoplinae) And Its Implications For Morphology And Biogeography, R. Wills Flowers

Insecta Mundi

Chalcosicya maya, new species, (Coleoptera: Chrysomelidae: Eumolpinae) is described and the species key of Blake (1951) is modified to accommodate it. This is the first known mainland species of this previously Antillean genus. Sclerotized rods in the apical segment of the ovipositor of Chalcosicya Blake and related genera are shown to be useful systematic characters within the eumolpine tribe Adoxini. Relationships with other genera suggest that Chalcosicya belongs to a clade derived from ancestors with a western Tethyian distribution.

Se describe Chalcosicya maya especie nueva (Coleoptera: Chrysomelidae: Eumolpinae). Esta es la primera especie conocida de tierra continente de este género …

The Milliped Genus Euryurus Koch, 1847 (Polydesmida: Euryuridae) West Of The Mississippi River; Occurrence Of E. Leachii (Gray, 1832) On Crowley’S Ridge, Arkansas, Rowland M. Shelley, Chris T. Mcallister, Henry W. Robison

Insecta Mundi

The milliped genus Euryurus Koch, 1847, and the species, E. leachii (Gray, 1832) (Polydesmida: Euryuridae), are recorded from three sites on the northern part of Crowley’s Ridge (Cross, Lee, and Poinsett counties), Arkansas, where the only prior familial records are of Auturus evides (Bollman, 1887). Coupled with the published locality of E. leachii in Phillips Co., at the southern extremity of the Ridge, the only known occurrences of both the genus and species in Arkansas and west of the Mississippi River are in this physiographic feature. The Arkansas population is geographically peripheral but anatomically intermediate between the two recognized subspecies, …

The Apterous Endemic Genus Omphra Dejean (Coleoptera: Carabidae: Helluonini) Of The Indian Subcontinent: Taxonomy With Notes On Habits And Distributional Patterns, Shiju T. Raj, Thomas K. Sabu, Zhao Danyang

Insecta Mundi

Among the four oriental genera of the tribe Helluonini, Omphra Dejean (Coleoptera: Carabidae), is unique for its endemism to the Indian subcontinent and aptery. High intraspecies variability in morphological characters and limited diagnostic information makes species differentiation of the genus Omphra a complicated task. The present study provides a description of a new species, Omphra drumonti n. sp. from the Western Ghats, redescriptions and a key to the species of Omphra, details of intraspecies variation, discussion of relationships between taxa and distributional patterns of the genus. Based on the distributional patterns in the Indian subcontinent and flightlessness of …

Rna Interference Of Nadph-Cytochrome P450 Reductase Results In Reduced Insecticide Resistance In The Bed Bug, Cimex Lectularius, Fang Zhu, Sarah Sams, Tim Moural, Kenneth F. Haynes, Michael F. Potter, Subba R. Palli

Entomology Faculty Publications

BACKGROUND: NADPH-cytochrome P450 reductase (CPR) plays a central role in cytochrome P450 action. The genes coding for P450s are not yet fully identified in the bed bug, Cimex lectularius. Hence, we decided to clone cDNA and knockdown the expression of the gene coding for CPR which is suggested to be required for the function of all P450s to determine whether or not P450s are involved in resistance of bed bugs to insecticides.

METHODOLOGY/PRINCIPAL FINDINGS: The full length Cimex lectularius CPR (ClCPR) cDNA was isolated from a deltamethrin resistant bed bug population (CIN-1) using a combined PCR strategy. Bioinformatics and in …

Bark Beetles And Fire: Two Forces Of Nature Transforming Western Forests, Gail Wells

Joint Fire Science Program Digests

Bark beetles are chewing a wide swath through forests across North America. Over the past few years, infestations have become epidemic in lodgepole and spruce-fir forests of the Intermountain West. The resulting extensive acreages of dead trees are alarming the public and raising concern about risk of severe fire. Researchers supported by the Joint Fire Science Program (JFSP) are examining the complicated relationship between bark beetles and wildfire, the two most influential natural disturbance agents in these forests. Are the beetles setting the stage for larger, more severe wildfires? And are fires bringing on beetle epidemics? Contrary to popular opinion, …

Midgut And Fat Body Bacteriocytes In Neotropical Cerambycid Beetles (Coleoptera: Cerambycidae), Olga Calderon, Amy Berkov

Publications and Research

Xylophagous insects derive nutrients from intractable substrates by producing or ingesting cellulolytic enzymes, or by maintaining associations with symbiotic microbes. Wood-boring cerambycid beetle larvae sometimes house maternally-transmitted endosymbiotic yeasts that are presumed to provide their hosts with nutritional beneÞts. These are thought to be absent from species in the large subfamily Lamiinae; nevertheless yeasts have been repeatedly isolated from the guts of neotropical lamiines. The objective of this study was to conduct transmission electron microscopy (TEM) studies of cerambycid larval midgut tissues to determine if gut yeasts were intracellular, or simply present in the gut lumen. Nine cerambycid larvae were …
