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 …

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.

Seasonal Abundance Of Maiestas Banda (Hemiptera: Cicadellidae), A Vector Of Phytoplasma, And Other Leafhoppers And Planthoppers (Hemiptera: Delphacidae) Associated With Napier Grass (Pennisetum Purpureum) In Kenya, Shinsaku Koji, Satoshi Fujinuma, Charles A.O. Midega, Hassan M. Mohamed, Tadashi Ishikawa, Michael R. Wilson, Manfred Asche, Simon Degelo, Tarô Adati, John A. Pickett, Zeyaur R. Khan

All Peer-Reviewed Publications

Napier grass (Pennisetum purpureum Schumach), the main fodder crop in eastern Africa, has recently been severely affected by Napier stunt disease, which is caused by phytoplasma. We have recently confirmed that a leafhopper, Maiestas banda (Kramer) transmits phytoplasma in Napier grass in Kenya. Several other species of leafhoppers (Cicadellidae) and planthoppers (Delphacidae) are also associated with Napier grass, and some could be potential vector(s) of phytoplasma, but little is known about phenology and movement activity of these insect groups. We monitored the populations of M. banda and other leafhoppers and planthoppers in Napier grass fields at two sites in western …

Species Composition Of Fruit Flies (Diptera: Tephritidae) In The Citrus Museum At The Agricultural Research Centre (Arc), Kade, Ghana, Caroline Ngichop Foba, Kwame Afreh-Nuamah, Maxwell Kelvin Billah, Daniel Obeng-Ofori

All Peer-Reviewed Publications

To determine species composition of fruit flies on six cultivated varieties of citrus (Late Valencia orange, Pineapple orange, Ovaleto, Mediterranean sweet lemon, Satsuma tangerine and Ortanique orange), a study was conducted at the Agricultural Research Centre, Kade, Ghana. Improvised Lynfield baited traps (methyl eugenol (ME) and citrus juice (CJ)) and McPhail baited traps (trimedlure (TML)) were used. Ripe infested fruits from the selected varieties were also collected and incubated. Tephritid fruit fly species from trapping were identified as Bactrocera invadens Drew, Tsuruta & White, Bactrocera cucurbitae (Coquillet), Ceratitis ditissima Munro, C. anonae Graham, C. capitata (Wiedemann), C. bremii Guerin-Meneville, Dacus …

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 …

Life History Of Oplostomus Haroldi (Coleoptera: Scarabaeidae) Under Laboratory Conditions And A Description Of Its Third Instar Larva, Ayuka T. Fombong, Fabian Haas, Paul N. Ndegwa, Lucy W. Irungu

All Peer-Reviewed Publications

The life history of Oplostomus haroldi (Witte), a recently reported pest of honeybee colonies in East Africa, was studied for the first time under laboratory conditions. Adult O. haroldi collected from beehives in the coastal part of Kenya were reared on a mixture of moist sterilized soil and cow dung. At 25-±-2-°C, 50-±-5% relative humidity and a 10-h light-14-h dark photoperiod, the laid eggs took 11.9-±-1.3 days to hatch into a curved pear-shaped scarabaeiform larva with a well-developed head and thoracic legs. The first, second and third larval instars lasted 14.6-±-2.6, 17.5-±-2.4 and 34.6-±-2.4 days, respectively. The pupal stage, which …

Oviposition Induced Volatile Emissions From African Smallholder Farmers' Maize Varieties, Amanuel Tamiru, Toby J.A. Bruce, Charles A.O. Midega, Christine M. Woodcock, Michael A. Birkett, John A. Pickett, Zeyaur R. Khan

All Peer-Reviewed Publications

Maize (corn), Zea mays, is a genetically diverse crop, and we have recently shown that certain open pollinated varieties (OPVs) of Latin American origin possess a trait not present in mainstream commercial varieties: they produce volatiles in response to stemborer oviposition that are attractive to stemborer parasitoids. Here, we tested whether a similar tritrophic effect occurs in the African OPVs 'Nyamula' and 'Jowi'. Herbivore induced plant volatiles (HIPVs) were collected from plants exposed to egg deposition by the stemborer Chilo partellus. In a four-arm olfactometer bioassay, the parasitic wasp Cotesia sesamiae preferred samples containing HIPVs from plants with eggs to …

A Novel Synthetic Odorant Blend For Trapping Of Malaria And Other African Mosquito Species, Wolfgang R. Mukabana, Collins K. Mweresa, Bruno Otieno, Philemon Omusula, Renate C. Smallegange, Joop J.A. Van Loon, Willem Takken

All Peer-Reviewed Publications

Estimating the biting fraction of mosquitoes is of critical importance for risk assessment of malaria transmission. Here, we present a novel odor-based tool that has been rigorously assessed in semi-field assays and traditional African villages for estimating the number of mosquitoes that enter houses in search of a blood meal. A standard synthetic blend (SB) consisting of ammonia, (S)-lactic acid, tetradecanoic acid, and carbon dioxide was complemented with isovaleric acid, 4,5 dimethylthiazole, 2-methyl-1-butanol, and 3-methyl-1-butanol in various combinations and concentrations, and tested for attractiveness to the malaria mosquito Anopheles gambiae. Compounds were released through low density polyethylene (LDPE) material or …

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 …

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 …
