Identification Of Muscidifurax Spp. By Polymerase Chain Reaction-Restriction Fragment Length Polymorphism, David B. Taylor, Allen L. Szalanski

Department of Entomology: Faculty Publications

Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the nuclear ribosomal ITS1 region was used to differentiate Muscidifurax (Hymenoptera: Pteromalidae) species which are parasitoids of filth fly pupae. Three restriction enzymes, Dpn 11, Mse I, and Taq I, produced restriction patterns which were diagnostic for the four species analyzed, M. raptor, M. raptorellus, M. uniraptor, and M. zaraptor. Seven other restriction enzymes were able to differentiate one or more of the species and can be used alone, or in combination with other enzymes, to verify identifications. No intraspecific variation was observed among the populations examined. The utility of the …

Influence Of Soybean Canopy Closure On Predator Abundances And Predation On Helicoverpa Zea (Lepidoptera: Noctuidae) Eggs, Aaron C. Anderson, Kenneth V. Yeargan

Entomology Papers from Other Sources

Planting soybeans [Glycine max (L.) Merrill early and in narrow rows is the most effective cultural control for preventing outbreaks of Helicoverpa zea (Boddie) in soybean. Soybeans planted early in narrow rows close canopy earlier in the season compared with soybeans planted late and in wide rows (i.e., leaves of plants from adjacent rows touch each other and eventually become densely interwoven). Although several lines of research have established dramatically higher mortality for corn earworm eggs or small larvae in closed canopies, none has found the cause. In 1994 and 1995, we planted soybeans in every combination of early …

Use Of Rubidium To Label Lysiphlebus Testaceipes (Hymenoptera: Braconidae), A Parasitoid Of Greenbugs (Homoptera: Aphididae), For Dispersal Studies, Odair A. Fernandes, Robert J. Wright, Karl H. Baumgarten, Z. B. Mayo

Department of Entomology: Faculty Publications

A reliable method of labeling is needed to study dispersal of the braconid parasitoid, Lysiphlebus testaceipes (Cresson), an important biological control of greenbugs, Schizaphis graminum (Rondani), on grain sorghum, Sorghum bicolor (L.) Moench. The feasibility of using aqueous solutions of rubidium chloride (RbCl) applied as a foliar spray or soil drench to label greenbugs and L. testaceipes developing within greenbugs was studied. Laboratory and field studies were conducted to identify the minimal concentration of RbCl to assure labeling of greenbugs and wasps, persistence of Rb throughout the wasp's life span, mobility of Rb to unsprayed sorghum leaves, and feasibility of …

Effects Of Shelterbelts On The Aerial Distribution Of Insect Pests In Muskmelon, Mary Ellen Dix, Laurie Hodges, James R. Brandle, Robert J. Wright, Mark O. Harrell

Department of Entomology: Faculty Publications

Sticky traps were used to measure how tree shelterbelts influence the abundance of crop insect pests and beneficial arthropods in muskmelon (Cucumis melo L.) plots in eastern Nebraska. Abundance of striped cucumber beetles {Acalymma vittatum Fabricius (Coleoptera: Chrysomelidae)} , southern corn rootworms {Diabrotica undecimpunctata howardi Barber (Coleoptera: Chrysomelidae)}, and northern corn rootworms {D. barberi Smith & Lawrence (Coleoptera: Chrysomelidae)} was similar in exposed and sheltered plots. Western corn rootworms {D. virgifera LeConte (Coleoptera: Chrysomelidae)} were significantly more abundant in exposed plots. More lady beetles (Coleoptera: Coccinellidae) and ichneumonid wasps (Hymenoptera: Ichneumonidae) were caught on traps …

Problems With The Interpretation Of Mark-Release-Recapture Data In Subterranean Termites (Isoptera: Rhinotermitidae), Anthony D. Curtis, Deborah A. Waller

Biological Sciences Faculty Publications

The Lincoln index (Peterson method) is frequently used to estimate animal population size in mark-release-recapture studies. We tested the accuracy of this method to estimate termite colony size using logs infested with termites that were maintained in the laboratory. Termites were fed paper towels dyed either with 0.05% or 0.1% (w/w) of the dye marker Nile blue and released into their host logs in the laboratory. Following recapture a week later, estimates of termite population size for termites dyed with 0.05% Nile blue, and were approximately 3 times greater for termites dyed with 0.1% Nile blue. Concentrations of 0.1% Nile …

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, …

Hydrellia Bicarina, N.Sp. (Diptera: Ephydridae), A Leafminer In Southern Watergrass, D. L. Deonier

Insecta Mundi

The species Hydrellia bicarina, n.sp. originally misidentified and described as Hydrellia spinicornis Cresson by Deonier (1971) is redescribed and illustrated. This species was first collectedon and reared from Southern Water Grass Luziola fluitans (Michaux) growing in shallow baytree swamps of southern Mississippi by Deonier (197 1). Based on the male and female genitalia and its natural history, this species is a member of the Hydrellia griseola species group.

Bibliography On Hydrellia Griseola Fallen (Diptera: Ephydridae) And Review Of Its Biology And Pest Status, Louis S. Hesler

Insecta Mundi

A bibliography is presented on Hydrellia griseola (FallBn), a cosmopolitan species of shore fly that is an agricultural pest throughout much of its range. The literature review includes 195 references and spans 180 years: from 1813, when H. griseola was first described (as Notophila griseola), to 1993. My review updates and extends by 110 years a previous review of this species. The host plant associations, bionomics, distribution, pest status, and control of this species are reviewed. The known host plants of larval H.griseola are listed. My survey of the literature supports the hypothesis that H. griseola is increasing its …

The Genus Vaejovis In Sonora, Mexico (Scorpiones, Vaejovidae), W. David Sissom

Insecta Mundi

The genus Vaejovis C. L. Koch in the Mexican state of Sonora is reviewed, based on the examination of numerous specimens from United States collections. Four species are reported to occur there: Vaejovis spinigerus (Wood), V. confusus Stahnke, V. sonorae Williams, and V. decipiens Hoffmann. Distributional information for all four species is updated, and a key is provided to facilitate identification. The subspecies V. spinigerus sonorensis Hoffmann is synonymized with V. spinigerus. The record for V. gravicaudus Williams on Isla Tiburon (Williams 1980) is demonstrated to be a misidentification resulting from atypical variation in the closely related V. spinigerus …

A New Bruchophagus From Glycyrrhiza Lepidota Pursh In The Northern Great Plains (Hymenoptera : Chalcidoidea : Eurytomidae), Burruss Mcdaniel, Arvid A. Boe

Native Plant Focused Publications

A new species, Bruchophagus grisselli McDaniel and Boe, which infests seeds of Glycyrrhiza lepidota Pursh (American licorice), is described and illustrated. It's known from South Dakota and North Dakota in the USA. A field study at 8 sites showed that B. grisselli has a wide distribution throughout the Dakotas.

Tetrigidae (Orthoptera) With Partly Exposed Wings, R. E. Blackith

Insecta Mundi

Long series of some species of Tetrigidae from south Asia show that the wings regularly project beyond the pronotal shield by some 15- 35 percent of their length, depending on the species. There is little intraspecific variation and alary polymorphism is not normally detectable. The role of such exposed wings is discussed and one new species is described. Most such species probably owe their evident relationship to evolution prior to the disintegration of the Gondwanaland super-continent.

Department Of Entomology Newsletter - No. 5, Part 1, 1988, George R. Manglitz

Hexapod Herald and Other Entomology Department Newsletters

When the last Newsletter was published in 1976 (No.4), it was assumed that it would be followed by another In 4 or 5 years. And indeed, considerable effort has been expended on the production of No.5. However, for various very good reasons No.5, although close to publication several times, aborted several times. Now largely because this is the centennial year of our Department, we feel that we can wait no longer. Because of that fact, the format of this Newsletter will be slightly different from those in the past. We have the "news" that you furnished about yourselves 5 or …

Voltinism And The Induction Of Aestival Diapause In The Colorado Potato Beetle, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), Maurice J. Tauber, Catherine A. Tauber, John J. Obrycki, Brian Gollands, Robert J. Wright

Department of Entomology: Faculty Publications

Field studies over 3 yr demonstrated that overwintering populations of the Colorado potato beetle in upstate New York and on Long Island are composed of adults from both the first and second summer generations. The two populations from the climatically different regions differ in their responses to environmental factors that influence voltinism. The critical photoperiod for aestival diapause induction is longer, and the induction of diapause by low temperature is greater, in the population from the cooler, inland locality (upstate New York) than in the population from the warm coastal area (Long Island). Under the long days of early summer, …

Effects Of Oviposition On Remating., Response To Pheromones., And Longevity In The Female Caribbean Fruit Fly., Anastrepha Suspensa (Diptera: Tephritidae), J. Sivinski, R. R. Heath

Entomology Papers from Other Sources

Female Caribbean fruit flies with oviposition opportunities remate frequently, two-thirds of them after 1 wk and approximately one-third every subsequent week. Those with limited chances to oviposit remate less frequently, and about half of them mate only once during their lifetime. Ovipositing females regain receptivity to male-produced pheromones within a week, unlike nonlaying females. Mortality rates also are higher for egglaying females.

Ecology, Behavior, And Distribution Of Blattella Asahinai (Orthoptera: Blattellidae) In Central Florida, Richard J. Brenner, R. S. Patterson, P. G. Koehler

Entomology Papers from Other Sources

The Asian cockroach, Blattella asahinai Mizukubo, a close relative of the German cockroach, B. germanica (L.), has been discovered in over 900 km² from Tampa to Lakeland, Fla., and is prevalent in citrus groves, wooded areas, lawns, and homes. Differentiation of the two species is best accomplished by the diagnostic behavior of the Asian cockroach-it is crepuscular (sunset) and nocturnal, readily flies, is attracted at sunset to light-colored or brightly lit surfaces, and lives outdoors in large numbers. Analyses of microhabitat composition of 86 trap sites indicate that the principal habitat of the Asian cockroach is leaf litter in …

Quantitative Analysis Of Temperature., Moisture., And Diet Factors Affecting Insect Development, David W. Hagstrum, George A. Milliken

Entomology Papers from Other Sources

Extensive published data on the developmental times of nine species of stored-product Coleoptera in relation to temperature, moisture, and diet were described by regression equations. At most temperatures, the order of relative influence of these factors on development was temperature > moisture > diet. However, moisture and diet influenced larval development more than temperature near the optimal temperature for development of each species. Egg, larval, and pupal stage durations at 27°C averaged 15, 66, and 19% of the total developmental time, respectively, at moistures above 12%, and 12, 72, and 15% of total developmental time at moistures below 12%. Similar percentages were …

Insect Succession In A Stored-Corn Ecosystem In Southeast Georgia, R. T. Arbogast, M. A. Mullen

Entomology Papers from Other Sources

Insect populations infesting a small bulk of corn stored in southeastern Georgia were followed for 8 yr by monthly sampling beginning 8 mo after the corn was placed in storage. The species composition of the insect community changed as the corn deteriorated. Nine species became dominant at some stage of succession. Sitotroga cerealella (Olivier) was the dominant species when the first sample was taken. It was succeeded a month later by Oryzaephilus surinamensis (L.), which declined rapidly after 2 mo of dominance and died out during the third year. Cryptolestes ferrugineus (Stephens) was dominant at various times during the first …

A North Florida Ant Fauna (Hymenoptera: Formicidae), Clifford Johnson

Insecta Mundi

This paper updates and summarizes the ant fauna of Alachua County, Florida, with two basic objectives. The first objective is presentation of a current, documented check-list consistent with existing taxonomy and an insight on species groups where taxonomic changes are likely in subsequent revisions. The second objection objective seeks to identify changes in the fauna since Van Pelt’s pioneer survey of 1948, and provide a basis for similar comparisons in the future.

The county consists of 902 square miles in north-central Florida and embraces essentially all inland habitats of the northern peninsula. This rich habitat variability is reflected in its …

Biochemical Evidence For Hybridization In Fire Ants, Robert K. Vander Meer, Clifford S. Lofgren, Francisco M. Alvarez

Entomology Papers from Other Sources

Hybridization in social insects has been predicted on a theoretical basis by Pearson (1983); however, it is not a commonly reported phenomenon among ants. We recently found support for this theory when we discovered unique biochemical evidence for hybridization between Solenopsis invicta Buren and Solenopsis richteri Forel, two South American fire ant species that were inadvertently introduced into the southeastern United States.

Minnesota's Response: The Mosquito Research Program, John Washburn, Nancy Read

Journal of the Minnesota Academy of Science

The Minnesota Mosquito Research Program (MMRP) was established in September 1984 in response to a request by Governor Perpich. The Minnesota Department of Health (MDH), as the lead agency, brought together a Working Group of distinguished North American experts to discuss the problems related to mosquito research and control. This Working Group- with advice from legislators and representatives from the community, environmental groups, and state and federal agencies- made recommendations for the development of a mosquito research and control program in Minnesota.

The Working Group divided its recommendations into two areas, research and administrative structure. An extensive research program in …
