Molecular Differentiation Of Alfalfa Weevil Strains (Coleoptera: Curculionidae), S. J. Erney, K. P. Pruess, S. D. Danielson, T. O. Powers

Department of Entomology: Faculty Publications

Mitochondrial DNA was amplified and sequenced from eastern, western, and Egyptian strains of alfalfa weevil, Hypera postica (Gyllenhal). Eastern and Egyptian weevils differed at only 2 nucleotide sites in 1,031 base pairs sequenced; western weevils differed by 5% sequence divergence. Three restriction sites were identified which separated eastern and western haplotypes. No intrastrain polymorphism was detected in 150 weevils from Nebraska. Collections from Lincoln in eastern Nebraska and Scottsbluff in western Nebraska were fixed for the eastern and western haplotypes, respectively. Eastern and western haplotypes were found together in the same fields in a broad overlap region in central Nebraska.

Population Genetics And Gene Variation In Screwworms (Diptera: Calliphoridae) From Brazil, David B. Taylor, Richard D. Peterson Ii, Gonzalo E. Moya-Borja

Department of Entomology: Faculty Publications

Allozyme variation in New World screwworm, Cochliomyia hominivorax (Coquerel), populations from Brazil was examined. Variability was observed in 8 of 13 enzyme loci and the frequency of the most common allele was <0.95 for seven loci. Observed and expected heterozygosities were 0.159 and 0.165, respectively. Comparisons of the Brazilian populations with previously studied populations from Costa Rica resulted in Nei's genetic distances of between 0.000 and 0. 006, with the greatest distance being between populations within Brazil. Comparisons with Mexican populations using only three loci resulted in genetic distances ≤0.031. Goodness-of-fit statistics for Hardy-Weinberg equilibrium and Wright's F statistics indicated small deviations from expected equilibrium genotype frequencies and low levels of differentiation between populations within Brazil. Differentiation among screwworm populations from Brazil, Costa Rica, and Mexico was minimal.

Estimation Of Rice Yield Losses Due To The African Rice Gall Midge, Orseolia Oryzivora Harris And Gagne, Souleymane Nacro, E. A. Heinrichs, D. Dakouo

Department of Entomology: Faculty Publications

The African rice gall midge, Orseolia oryzivora Harris and Gagne (Diptera: Cecidomyiidae), is an important pest of rice, Oryza sativa, in Burkina Faso as well as other countries in West and East Africa. In spite of its importance, little is known regarding the relationship between gall midge populations and grain yield losses. To determine yield losses, the gall midge was reared in cages, and adult midges were placed on caged plants of the rice variety ITA 123 at different population levels. The seven treatments consisted of different numbers of insects infested on the plants: 0 insect pairs (noninfested check), …

Environmental And Edaphic Effects On Western Corn Rootworm (Coleoptera: Chrysomelidae) Overwintering Egg Survival, L. D. Godfrey, Lance J. Meinke, Robert J. Wright, Gary L. Hein

Department of Entomology: Faculty Publications

Western corn rootworm, Diabrotica virgifera virgifera LeConte, overwintering egg survival was studied at 3 soil depths (7.5, 15, and 30 cm), 3 soil textures (silty clay loam, loam, and sandy loam), and 2 surface residue treatments (with and without surface cover) at an eastern Nebraska site in 1989-1990 and 1990-1991. At a western Nebraska site, egg survival was evaluated at 3 soil depths (7.5, 15, and 30 cm), 2 surface residue regimes (with and without surface cover) within a fine sandy loam soil in 1989-1990. Overall, egg survival was low (30.0%) and intermediate (41.0%) at the eastern and western sites, …

Additions To The Known Range Of Bembidion Rufotinctum Chaudoir (Coleoptera: Carabidae: Bembidiini), Paul M. Choate, Angela L. Choate

Insecta Mundi

Previously known from northeastern United States and Virginia, Bembidion rufotinctum Chaudoir is recorded from North Carolina, Tennessee, South Carolina, and Georgia. Habitat preference for this species appears to remain the same throughout its range. Specimens may be found hiding in cracks in rocks exposed to rapidly flowing water. The presence of this species may be indicated by Pentacora ligata (Say)(Hemiptera: Saldidae) that occurs on the same rocks.
