A Morphological And Mtdna Analysis Of The Badlands Tiger Beetle, Cicindela (S. Str.) Decemnotata Say, 1817 (Coleoptera: Carabidae: Cicindelinae) With The Description Of Three New Subspecies, C. Barry Knisley, M. Ryan Woodcock, Michael G. Kippenhan

Insecta Mundi

We conducted a morphological and mtDNA analysis of Cicindela decemnotata Say (Coleoptera: Carabidae: Cicindelinae) populations from throughout its geographic range to determine the extent of variation within the species and to assess the validity of subspecific names. The morphological study included an analysis of traditional subspecific characters including elytral color and maculations. These results provided evidence for the recognition of four subspecies of C. decemnotata, three of which are new: 1. C. d. decemnotata Say usually with green to dark green dorsal coloration and complete elytral maculations; it is widely distributed from Canada south to northern New Mexico and …

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 …

2011 Soybean Insect Losses In The Southern Us, F. R. Musser, A. L. Catchot Jr., J. A. Davis, D. A. Herbert Jr., B. R. Leonard, G. M. Lorenz, T. Reed, D. D. Reisig, S. D. Stewart

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 …

Spatial Genetic Variation Among Spodoptera Frugiperda (Lepidoptera: Noctuidae) Sampled From The United States, Puerto Rico, Panama, And Argentina, Difabachew K. Belay, Pete L. Clark, Steven R. Skoda, David J. Isenhour, Jaime Molina-Ochoa, Claudia Gianni, John E. Foster

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 …

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 …

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 …

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 …
