Notes On Distribution And Hosts Of Hylesinus Mexicanus (Wood) (Coleoptera: Curculionidae: Scolytinae), A Pest On Olea Europaea Linnaeus, Jesús Rómero Napoles, Thomas H. Atkinson

Insecta Mundi

Significant new host and distribution records are presented for Hylesinus mexicanus (Wood) (Coleoptera: Curculionidae: Scolytinae), including its pest potential on cultivated olives. Hylesinus mexicanus is similar to H. fasciatus LeConte and information presented here suggests that the distinctiveness of these two species needs to be re-examined.

Centipedes And Millipeds (Arthropoda: Diplopoda, Chilopoda) From Saba Island, Lesser Antilles, And A Consolidation Of Major References On The Myriapod Fauna Of “Lesser” Caribbean Islands, Rowland M. Shelley, Derek S. Sikes

Insecta Mundi

The chilopod, Cryptops hortensis (Donovan, 1810) (Scolopendromorpha: Cryptopidae), and the diplopods, Pseudospirobolellus avernus (Butler, 1876) (Spirobolida: Pseudospirobolellidae) and Oxidus gracilis (C. L. Koch, 1847) (Polydesmida: Paradoxosomatidae), are newly recorded from Saba Island, Lesser Antilles, which also harbors one additional scolopendromorph and four more chilognath millipeds. Except for the plausibly native scolopendrid centipede, Scolopendra alternans Leach, 1813, all are human introductions. Concentrated sampling is needed in the cloud/elfin forest atop Mt. Scenery, where indigenous millipeds may reside, and with extraction techniques throughout the island, to potentially document the diplopod subclass Penicillata. Nine small Caribbean islands in addition to Saba have been …

Two Species Of Compsus Schoenherr, New Citrus Pests From Colombia (Coleoptera: Curculionidae: Entiminae), Charles W. O’Brien, Jorger Peña

Insecta Mundi

Two species of the weevil genus Compsus Schoenherr (Coleoptera: Curculionidae: Entiminae) from Colombia are redescribed: C. obliquatus Hustache and C.viridivittatus (Guérin-Méneville). A key by Hustache in 1938, to 33 of the 34 recognized species of Colombian Compsus then known, is modified to include the one additional species. Habitus illustrations of males and females of the two species and illustrations of selected parts of the male and female genitalia are included. Nearly all of the specimens of these two species were collected on various species or varieties of citrus, indicating their potential as citrus pests in the future.

Parochlus Kiefferi (Garrett, 1925) In Nebraska (Diptera: Chironomidae), Barbara Hayford

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

A rare species of nonbiting aquatic midge, Parochlus kiefferi (Garrett, 1925), was discovered in Squaw Creek in the Pine Ridge of northwest Nebraska. Parochlus is a genus of midge found throughout the Southern Hemisphere and is only represented by this one species in the Northern Hemisphere. The typical North American species distribution of P. kiefferi includes high alpine and northern latitude streams, so the collection of P. kiefferi from a low elevation and low-latitude stream in Nebraska represents a range extension for the species. A survey for P. kiefferi from 83 samples from 53 stream sites in northern Nebraska yielded …

Ecology Of Tenodera Sinensis And Tenodera Angustipennis (Mantodea: Mantidae) In Eastern Virginia, Cory A. Gall

Biological Sciences Theses & Dissertations

My study, conducted on the Wildlife Refuge located on Virginia's Eastern Shore, focused on the life history, ecology, and intra- and interspecies interaction of Tenodera sinensis and T. angustipennis. Field methods included capture-mark-recapture, species, sex, and developmental life stage identification, and recorded key developmental milestones. Also, to analyze food-limiting growth, a laboratory cohort was fed ad lib, with lab and field cohorts measured bi-weekly and their mean weekly growth was compared.

When compared to a lab cohort, Tsinensis field mantises were shown not to be growth limited by the abundance of prey. In 2011, the dates of several developmental stages …

Sensory Morphology And Chemical Ecology Of The Stable Fly, Stomoxys Calcitrans: Host-Seeking And Ovipositional Selection, Khanobporn Tangtrakulwanich

Department of Entomology: Dissertations, Theses, and Student Research

Stable flies cause stress and discomfort to cattle, and other mammals, including humans and pets. Economic losses from stable flies to the U.S. cattle industry from loss of milk production and cattle weight gain exceed $2 billion annually.

Traditional stable fly management employing sanitation and insecticides is costly and often fails to provide acceptable levels of control. A novel method for managing stable flies involves the use of attractants and repellents. This approach could be used to enhance the current level of stable fly control and ultimately be incorporated into a sustainable stable fly management program.

Gravid females’ stable flies …

A Preliminary Report On The World Species Of Bemisia Quaintance And Baker And Its Congeners (Hemiptera: Aleyrodidae) With A Comparative Analysis Of Morphological Variation And Its Role In The Recognition Of Species, Raymond Gill

Insecta Mundi

Extreme economic effects globally of various populations of the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) led to an in depth study of the morphology of that species as well as that of numerous other species of whiteflies in the genus Bemisia Quaintance and Baker and other similar appearing species. The data collected are presented here as illustrations of the puparia (fourth instar nymphal stages) and discussions of morphology as it relates to species and generic separations within this closely knit group of insects. A brief history of the pest outbreaks of B. tabaci is given and an overview of the …

Department of Entomology: Faculty Publications

Spatial genetic variability of the fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), was studied by collecting samples from 31 locations in the United States, Argentina, Panama, and Puerto Rico, and then using amplified fragment length polymorphism to detect genetic variation. Analysis of molecular variance showed significant genetic variation in fall armyworm among all (28%) sample locations and individuals within (71%) sample locations; genetic variation of fall armyworm was minimal between sample locations grouped into regions. The pairwise fixation index (F_ST) comparisons showed significant genetic differentiation (0.288) among the 31 locations. However, dendrograms of results from cluster …

Genetic Differentiation Of Western Corn Rootworm Populations (Coleoptera: Chrysomelidae) Relative To Insecticide Resistance, Hong Chen, Haichuan Wang, Blair D. Siegfried

Department of Entomology: Faculty Publications

Abstract

As the single most important pest of field corn, Zea mays L., throughout most of the Corn Belt, the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), has undergone repeated selection for resistance to a variety of insecticides that persist widely among Nebraska populations. In this study, we used 11 microsatellite markers to genotype two populations with high levels of resistance to methyl-parathion and aldrin (Polk and Stromsburg), two populations with low and intermediate levels of resistance (Mead and Clay Center) from Nebraska, and one population from outside the Corn Belt (Safford, Arizona). The genetic diversity measured by …

Bean Leaf Beetle (Coleoptera: Chrysomelidae) And Bean Pod Mottle Virus In Soybean: Biology, Ecology, And Management, Buyung A. R. Hadi, Jeffrey D. Bradshaw, Marlin E. Rice, John J. Hill

Department of Entomology: Faculty Publications

Bean leaf beetle, Cerotoma trifurcata (Förster), is a pest of soybean found in many production areas in the United States. The bean leaf beetle larvae feed on soybean root nodules, whereas the adults feed on the above ground parts of soybean such as cotyledon, leaves, and pods. Bean leaf beetle is also a very efficient vector of Bean pod mottle virus, a widespread virus of soybean in the south and southeastern United States with recent expansion into the north central region of the country. This article summarizes bean leaf beetle biology, ecology, and its impact on soybean production in the …
