Book Review: Brentidae Of The World (Coleoptera: Curculionoidea) (Sforzi, A., And L. Bartolozzi), Nico M. Franz

Insecta Mundi

This new book on the Brentidae of the World was originally conceived as an update of Richard Kleine’s (1938) checklist. It turned out to be much more. The checklist evolved into a comprehensive and meticulously annotated catalogue. A long introductory section was added, and enriched with clear illustrations and superb color photographs of charismatic specimens. It could stand on its own as a smaller book on the biology and taxonomic history of brentid beetles. The editors also enlisted a select group of experts to contribute four chapters on lineages recently placed within or close to the family. The result is …

Close-Range Host Searching Behavior Of The Stemborer Parasitoids Cotesia Sesamiae And Dentichasmias Busseolae: Influence Of A Non-Host Plant Melinis Minutiflora, Linnet S. Gohole, William A. Overholt, Zeyaur R. Khan, Louise E.M. Vet

All Peer-Reviewed Publications

Studies were conducted on the host searching behavior of the larval parasitoid Cotesia sesamiae (Cameron) (Hymenoptera: Braconidae) and the pupal parasitoid Dentichasmias busseolae Heinrich (Hymenoptera: Ichneumonidae), both of which attack lepidopteran (Crambidae, Noctuidae) cereal stemborers. The behavior of D. busseolae was observed in a diversified habitat that consisted of stemborer host plants (maize, Zea mays L. and sorghum, Sorghum bicolor (L). Moench (Poaceae)) and a non-host plant (molasses grass, Melinis minutiflora Beauv. (Poaceae)), while C. sesamiae was observed separately on host plants and molasses grass. In previous olfactometer studies, C. sesamiae was attracted to molasses grass volatiles while D. busseolae …

Immunological Assessment Of An Insecticide Resistance-Associated Esterase In The Western Corn Rootworm, Xuguo Zhou, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

In previous investigations, we have determined that organophosphate resistance in the western corn rootworm, Diabrotica virgifera virgifera, is at least partially attributed to a group of non-specific carboxylesterases referred to as group II. Antiserum raised against a purified 66-kDa group II esterase is specific for the denatured enzyme. This antiserum reacts similarly with both beetle homogenates from resistant and susceptible populations, although there is much higher signal intensity in immunoblots of resistant relative to susceptible beetles. These results suggest that overproduction of group II esterases is the underlying basis of esterase-mediated resistance in D. v. virgifera by demonstrating that …

Stochastic Dietary Restriction Using A Markov-Chain Feeding Protocol Elicits Complex, Life History Response In Medflies, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Ying Zhang, Lawrence G. Harshman

Lawrence G. Harshman Publications

Lifespan in individually housed medflies (virgins of both sexes) and daily reproduction for females were studied following one of 12 dietary restriction (DR) treatments in which the availability of high-quality food (yeast–sugar mixture) for each fly was based on a Markov chain feeding scheme – a stochastic dietary regime which specifies that the future dietary state depends only on the present dietary state and not on the path by which the present state was achieved. The stochastic treatments consisted of a combination of one of four values of a ‘discovery’ parameter and one of three values of a ‘persistence’ parameter. …

Phylogenetic Reconstruction Of Exoristinae Using Molecular Data: A Bayesian Re-Analysis, John O. Stireman Iii

Biological Sciences Faculty Publications

A few years ago I published the results of a phylogenetic analysis of New World Exoristinae based on molecular data from two genes, 28S rDNA and Elongation Factor 1-alpha (Stireman 2002). In that study I employed parsimony, neighbor joining, and maximum likelihood inference methods to generate phylogenetic reconstructions, and explored a variety of weighting schemes and combinations of the sequence data (i.e. each gene separately and both together). The results of these analyses generally supported recent taxonomic hypotheses (e.g., Herting 1984; Wood 1987; O’Hara and Wood 2004). For example, Tachinidae and Exoristinae were reconstructed as monophyletic in most analyses, as …

Tritrophic Interaction Of Parasitoid Lysiphlebus Testaceipes (Hymenoptera: Aphidiidae), Greenbug, Schizaphis Graminum (Homoptera: Aphididae), And Greenbug-Resistant Sorghum Hybrids, Mahmut Dogramaci, Z. B. Mayo, Robert J. Wright, John C. Reese

Department of Entomology: Faculty Publications

Interactions of the parasitoid Lysiphlebus testaceipes (Cresson) and the greenbug, Schizaphis graminum (Rondani), on greenbug-resistant ‘Cargill 607E’ (antibiosis), ‘Cargill 797’ (primarily tolerance), and -susceptible ‘Golden Harvest 510B’ sorghum, Sorghum bicolor (L.) Moench, were tested using three levels of biotype I greenbug infestation. The parasitoid infestation rate was 0.5 female and 1.0 male L. testaceipes per plant. For all three greenbug infestation levels, the parasitoid brought the greenbug under control (i.e., prevented the greenbugs from killing the plants) on both resistant hybrids, but it did not prevent heavy leaf damage at the higher greenbug infestation rates. At the low greenbug infestation …

Comparative Performance Of The Mbita Trap, Cdc Light Trap And The Human Landing Catch In The Sampling Of Anopheles Arabiensis, An. Funestus And Culicine Species In A Rice Irrigation In Western Kenya, Evan M. Mathenge, Gedion O. Misiani, David O. Oulo, Lucy W. Irungu, Paul N. Ndegwa, Tom A. Smith, Gerry F. Killeen, Bart G.J. Knols

All Peer-Reviewed Publications

Background: Mosquitoes sampling is an important component in malaria control. However, most of the methods used have several shortcomings and hence there is a need to develop and calibrate new methods. The Mbita trap for capturing host-seeking mosquitoes was recently developed and successfully tested in Kenya. However, the Mbita trap is less effective at catching outdoor-biting Anopheles funestus and Anopheles arabiensis in Madagascar and, thus, there is need to further evaluate this trap in diverse epidemiological settings. This study reports a field evaluation of the Mbita trap in a rice irrigation scheme in Kenya. Methods: The mosquito sampling efficiency of …

Host Genotype By Parasite Genotype Interactions Underlying The Resistance Of Anopheline Mosquitoes To Plasmodium Falciparum, Louis Lambrechts, Jean Halbert, Patrick Durand, Louis C. Gouagna, Jacob C. Koella

All Peer-Reviewed Publications

Background: Most studies on the resistance of mosquitoes to their malaria parasites focus on the response of a mosquito line or colony against a single parasite genotype. In natural situations, however, it may be expected that mosquito-malaria relationships are based, as are many other host-parasite systems, on host genotype by parasite genotype interactions. In such systems, certain hosts are resistant to one subset of the parasite's genotypes, while other hosts are resistant to a different subset. Methods: To test for genotype by genotype interactions between malaria parasites and their anopheline vectors, different genetic backgrounds (families consisting of the F1 offspring …

Report Of A Novel Biological Association For Paracrias Huberi Gumovsky (Hymenoptera: Eulophidae) With Redescription Of The Female And Description Of The Unknown Male, M. A. Metz, M. W. Gates, M. E. Schauff

USDA Systematic Entomology Laboratory

The female of Paracrias huberi Gumovsky (Hymenoptera: Eulophidae) is redescribed and the previously unknown male described from material collected by George B. Vogt near Plummers Island, Maryland. The species is diagnosed and placed within the current phylogenetic concept for the genus Paracrias. Collection records indicate this species was reared from Homoeolabus analis Illiger (Coleoptera: Attelabidae), which is a leaf-rolling herbivore of Quercus spp. and Castanea spp. (Fagales: Fagaceae), thus expanding the potential host guild range of the genus Paracrias and the known biology of the species. In addition, these records report an association with Q. prinus L., a species …
