A New Genus And Species Of Brontine Silvanidae From Australia (Coleoptera: Cucujoidea), Michael C. Thomas

Insecta Mundi

Notophanus bellicilifer Thomas, n. gen., n. sp., is described and illustrated from Australia. A key is provided to all of the species of the tribe Brontini known to occur in Australia.

Examination of specimens from the Australian National Insect Collection (ANIC) revealed a single specimen in the silvanid subfamily Brontinae from Victoria different from any known Australian genus. Further searching of the collection produced additional specimens from Victoria and South Australia. Interestingly, the first specimen examined possessed hind wings, while all the other specimens lacked hind wings. There appear to be no differences other than the lack of metathoracic wings …

Beetles (Coleoptera: Histeridae And Scarabaeidae) From Previously Unsampled Populations Of Pocket Gopher Burrows In Louisiana, Matthew B. Connior

Insecta Mundi

Pocket gopher burrows (Rodentia: Geomyidae) were sampled from five previously unsampled localities in northern Louisiana to determine the associated faunal composition of Histeridae and Scarabaeidae (Coleoptera). Sampling produced four species of Histeridae and seven species of Scarabaeidae, all of which had been previously reported from Louisiana. The most commonly collected scarab beetle was Cryptoscatomaseter haldemani (Horn) followed by Geomyphilus insolitus (Brown). Onthophilus kirni Ross was the most commonly collected hister beetle.

A New Species Of Phyllophaga Harris From The Island Of Navassa In The Caribbean (Coleoptera: Scarabaeidae: Melolonthinae), Robert E. Woodruff, Warren E. Steiner

Insecta Mundi

The small Caribbean island of Navassa (U.S. possession) is unoccupied by humans, but recent surveys have detected a surprising number of endemic (precinctive) invertebrates. A new species of May beetle, Phyllophaga navassa, is here described and compared to the Hispaniolan Phyllophaga fauna.

The large genus Phyllophaga Harris is estimated to contain over 500 species (Morón 1997:229); perhaps the largest genus of New World Scarabaeidae. In the recent revision of the species for the island of Hispaniola (Woodruff and Sanderson 2004), 48 species were treated, of which 22 were described as new. All 48 are endemic only to Hispaniola, and …

Tracking The Feeding Patterns Of Tsetse Flies (Glossina Genus) By Analysis Of Bloodmeals Using Mitochondrial Cytochromes Genes, Catherine N. Muturi, Johnson O. Ouma, Imna I. Malele, Raphael M. Ngure, Jane J. Rutto, Klaus M. Mithöfer, John Enyaru, Daniel K. Masiga

All Peer-Reviewed Publications

Tsetse flies are notoriously difficult to observe in nature, particularly when populations densities are low. It is therefore difficult to observe them on their hosts in nature; hence their vertebrate species can very often only be determined indirectly by analysis of their gut contents. This knowledge is a critical component of the information on which control tactics can be developed. The objective of this study was to determine the sources of tsetse bloodmeals, hence investigate their feeding preferences. We used mitochondrial cytochrome c oxidase 1 (COI) and cytochrome b (cytb) gene sequences for identification of tsetse fly blood meals, in …

Dry Season Ecology Of Anopheles Gambiae Complex Mosquitoes At Larval Habitats In Two Traditionally Semi-Arid Villages In Baringo, Kenya, Albert O. Mala, Lucy W. Irungu, Josephat I. Shililu, Ephantus J. Muturi, Charles C. Mbogo, Joseph K. Njagi, John I. Githure

All Peer-Reviewed Publications

Background: Pre-adult stages of malaria vectors in semi-arid areas are confronted with highly variable and challenging climatic conditions. The objective of this study was to determine which larval habitat types are most productive in terms of larval densities in the dry and wet seasons within semi-arid environments, and how vector species productivity is partitioned over time. Methods: Larval habitats were mapped and larvae sampled longitudinally using standard dipping techniques. Larvae were identified to species level morphologically using taxonomic keys and to sub-species by polymerase chain reaction (PCR) methods. Physical characteristics of larval habitats, including water depth, turbidity, and presence of …

Isolation By Distance Explains Genetic Structure Of Buggy Creek Virus, A Bird-Associated Arbovirus, Abinash Padhi, Amy T. Moore, Mary Bomberger Brown, Jerome E. Foster, Martin Pfeffer, Charles R. Brown

School of Natural Resources: Faculty Publications

Many of the arthropod-borne viruses (arboviruses) show extensive genetic variability and are widely distributed over large geographic areas. Understanding how virus genetic structure varies in space may yield insight into how these pathogens are adapted to and dispersed by different hosts or vectors, the relative importance of mutation, drift, or selection in generating genetic variability, and where and when epidemics or epizootics are most likely to occur. However, because most arboviruses tend to be sampled opportunistically and often cannot be isolated in large numbers at a given locale, surprisingly little is known about their spatial genetic structure on the local …

Improvement Of A Synthetic Lure For Anopheles Gambiae Using Compounds Produced By Human Skin Microbiota, Niels O. Verhulst, Phoebe A. Mbadi, Gabriella Bukovinszkiné Kiss, Wolfgang R. Mukabana, Joop J.A. Van Loon, Willem Takken, Renate C. Smallegange

All Peer-Reviewed Publications

Background. Anopheles gambiae sensu stricto is considered to be highly anthropophilic and volatiles of human origin provide essential cues during its host-seeking behaviour. A synthetic blend of three human-derived volatiles, ammonia, lactic acid and tetradecanoic acid, attracts A. gambiae. In addition, volatiles produced by human skin bacteria are attractive to this mosquito species. The purpose of the current study was to test the effect of ten compounds present in the headspace of human bacteria on the host-seeking process of A. gambiae. The effect of each of the ten compounds on the attractiveness of a basic blend of ammonia, lactic and …

Imported Fire Ant(Hymenoptera: Formicidae) Mound Distribution Relationships In Connection To The Heterogeneity Of Ten Christmas Tree Farm Landscapes In Mississippi, S. R. Self, T. E. Nebeker

Midsouth Entomologist

Ten Christmas tree farms were selected as research sites across Mississippi. At each site a 10-percent inventory was established. Plots were chosen randomly, and all imported fire ant (IFA) (Hymenoptera: Formicidae, Solenopsis spp.) mound positions inside the plot boundaries were captured as global positioning system (GPS) points. Mound points, along with their corresponding volumes (cm3), were recorded and uploaded into ESRI® ArcMap for analysis. Thirteen variables were selected to represent the heterogeneity of these landscapes. Among those variables, the species, height, and diameter of every Christmas tree located inside a plot were recorded, along with average grass height, distance to …

Effect Of Infection By Metarhizium Anisopliae (Hypocreales: Clavicipitaceae) On The Feeding And Oviposition Of The Pea Leafminer Liriomyza Huidobrensis (Diptera: Agromyzidae) On Different Host Plants, L. N. Migiro, N. K. Maniania, A. Chabi-Olaye, A. Wanjoya, J. Vandenberg

All Peer-Reviewed Publications

The effect of fungal infection by Metarhizium anisopliae on feeding and oviposition of adult Liriomyza huidobrensis was examined on three host plants, faba bean (Vicia faba), French bean (Phaseolus vuklgaris) and snow pea (Pisum sativum) in the laboratory. Flies were contaminated with dry conidia and allowed to feed and oviposit on the different host plants. Mortality in L. huidobrensis varied between 14% and 20% in the controls and between 77% and 100% in fungal treatments 120h post-infection for the three host plants. L. huidobrensis made more punctures (47.3-52.6cm-2) in the control than in the fungal treatments (23.1-26.9cm-2) for the three …

2010 Soybean Insect Losses For Mississippi, Tennessee, And Arkansas, F. R. Musser, G. M. Lorenz, S. D. Stewart, A. L. Catchot Jr.

Midsouth Entomologist

Survey-based soybean insect losses provide a glimpse of current soybean management practices and allow the detection of evolving trends. This survey was initiated in Mississippi in 2004, Tennessee in 2008, and Arkansas in 2009. The 2010 survey shows stink bugs and corn earworm caused similar amounts of damage in the region. Combined, these two insects caused more than half of all insect losses in 2010. Insect scouting and the adoption of seed treatments were at similar levels compared to 2009.

Efficacy Of Cotton Expressing Pyramided Bacillus Thuringiensis Insecticidal Proteins Against Lepidopteran Pest, D. S. Akin, S. D. Stewart, M. B. Layton, J. A. Mills

Laboratory, greenhouse, and field experiments were conducted to evaluate the efficacy of cotton (Gossypium hirsutum L.) expressing two proteins of Bacillus thuringiensis Berliner (‘Bollgard II’ expressing Cry1Ac + Cry2Ab, Monsanto Company, St. Louis, MO) against economically important lepidopteran pests in Mississippi. Results from leaf assays conducted in the laboratory indicate that Bollgard II cotton caused significantly higher mortality and growth inhibition of Helicoverpa zea (Boddie), Heliothis virescens (F.), Spodoptera frugiperda (J.E. Smith), S. exigua (Hubner), Pseudoplusia includes (Walker), and Estigmene acrea (Drury) than Cry1Ac onlyand non-Bt cotton. In greenhouse studies, Bollgard II cotton provided significantly enhanced protection against common defoliating …

Diversity Of Agromyzidae And Associated Hymenopteran Parasitoid Species In The Afrotropical Region: Implications For Biological Control, Robert Musundire, Adenirin Chabi-Olaye, Bernhard Löhr, Kerstin Krüger

All Peer-Reviewed Publications

Agromyzidae (Diptera) is a family with many species of economic importance on agricultural plants. However, many species are attacked by hymenopteran parasitoids which are known to be habitat rather than species specific. In the Afrotropical region, information about agromyzid and parasitoid diversity in different habitats is scattered in literature. Our aim was to assemble this dispersed information and discuss future needs of biological control efforts against invasive agromyzids in the Afrotropics. From published information, 581 agromyzid records comprising 302 species from 20 genera were recorded from 48 plant families. Parasitoids (90 records) were associated only with 20 agromyzid species belonging …

Detection Of Phytoplasma By Loop-Mediated Isothermal Amplification Of Dna (Lamp), E. Obura, D. Masiga, F. Wachira, B. Gurja, Z. R. Khan

All Peer-Reviewed Publications

Napier stunt phytoplasma (16SrXI and 16SrIII) in eastern Africa is a serious threat to the expansion of Napier grass (Pennisetum purpureum) farming in the region, where it is widely cultivated as fodder in zero grazing livestock systems. The grass has high potential for bio-fuel production, and has been adopted by farmers as a countermeasure to cereal stem borer Lepidoptera, since it attracts and traps the insect. Diagnosis of stunt phytoplasma have been largely by nested polymerase chain reaction (nPCR) targeting the 16S rRNA gene. However, the method is laborious, costly and technically demanding. This investigation has developed a simpler but …

Transfected Mosquito Vectors, Stephen L. Dobson
