Residual Toxicity Of Some Fluoroaliphatic Sulfones To The Red Imported Fire Ant, C. S. Lofgren, W. A. Banks, R. K. Vander Meer, D. F. Williams

Entomology Papers from Other Sources

Thirty-six fluoroaliphatic sulfones were tested to determine their residual toxicity to Solenopsis invicta Buren in soil. Six of the compounds gave >90% kill of the ants after they were exposed for 4 days at 10 ppm. When tested at 1.0 ppm, only one compound, AI3-10841, gave appreciable mortality. This compound was tested at 10 ppm in soil held outdoors under ambient summer conditions. Mortality 8 days following initial exposure to samples of this soil was 100% for 12 weeks and 91 to 100% from 20 to 36 weeks.

Some Factors Affecting Male Mating Success In The Giant Waterbug (Belostoma Flumineum Say), Karyn S. Crisman

Masters Theses

Giant waterbugs (Subfamily Belostomatinae) are interesting in that males provide exclusive post-copulatory care of young. This unusual behavior makes this species an excellent study system for investigations of sexual selection theory because in such systems, sex role reversals are predicted. Previous studies indicate that role reversal in giant waterbugs is not complete because males still court females. It is assumed that from this courtship display females can assess male quality and "choose" a superior male. If some males are chosen over others then differential mating success results. This study was undertaken to ascertain some of the factors that affect male …

Pheromone Delivery System: Western Corn Rootworm (Coleoptera: Chrysomelidae) Pheromone Encapsulation In A Starch Borate Matrix, Lance J. Meinke, Z. B. Mayo, Thomas J. Weissling

Department of Entomology: Faculty Publications

Western corn rootworm, Diabrotica virgifera virgifera LeConte, sex pheromone, racemic 8-methyl-2-decyl-propanoate (MDP) was successfully encapsulated in a starch borate (5B) matrix creating a controlled release granular formulation. The release rate of MDP from starch borate granules was attractive to male D. virgifera at high and low D. virgifera population levels in field corn. Male D. virgifera were attracted to the 5B-MDP granules throughout the growing season, but efficacy declined during the period of peak female D. virgifera emergence and corn pollination. The 5B-MDP delivery system was as effective as a septa-MDP delivery system, and 5B-MDP formulations had a shelf life …

Colony Survivorship In Pogonomyrmex Occidentalis, Western Harvester Ant, In Western Nebraska, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Little is known about the life span of individual ant colonies (Keeler, 1981), even though the dynamics of some species, such as harvester ants, are crucial to the structure of plant and animal communities (e.g., Brown et al., 1979). This note reports the results of 10 years of observations on a population of harvester ants.

Fifty-six mounds of Pogonomyrmex occidentalis Cresson (Hymenoptera: Formicidae), western harvester ant, were permanently marked with aluminum tags in August 1977. The site, about 1 ha just south of the University of Nebraska's Cedar Point Biological Station, Keith Co., Nebraska, was within a pasture subject to …

A Plant Root Warmer For Studying Phytophagous Insect Development And Fecundity At Temperatures Below Host Plant Tolerance, D. H. Akey, G. D. Butler, J. W. Radin

Entomology Papers from Other Sources

A simple root-warming device maintains the plants' roots at a higher temperature than that at which the rest of the plant is held. This permits the host plant to retain turgor, not wilt, and therefore remain suitable for and attractive to phytophagous insects. The technique was demonstrated in a development and fecundity test using the cotton aphid, Aphis gossypii Glover, reared on cotton seedlings, Gossypium hirsutum L., at foliar temperatures of 10.0 and 12.5°C. Root temperatures were held at 20°C. The device was also tested at a foliar temperature of 7.5°C in an additional fecundity test. In a control test, …

Geographical Variation In Responses To Photoperiod And Temperature By Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae) During And After Dormancy, Maurice J. Tauber, Catherine A. Tauber, John J. Obrycki, Brian Gollands, Robert J. Wright

Department of Entomology: Faculty Publications

The intensity of diapause has a distinct seasonal pattern in the Colorado potato beetle, Leptinotarsa decemlineata (Say). During August, temperature and photoperiod only slightly affected the very intense diapause in field populations. By summer's end, diapause intensity diminishes, but photoperiod and temperature maintain diapause. Subsequently, the beetles lose their responsiveness to photoperiod at high temperatures (approximately 200c), but at low temperatures (18-15°C) the beetles remain photoperiodically sensitive after emerging from the soil and initiating oviposition in the spring. Mated females that overwinter can lay fertile eggs without mating in the spring. Populations from climatically different areas in New York state …

Book Review: Glyphipterigidae Auctorum Sensu Lato, J. B. Heppner

Insecta Mundi

This is another volume in the extensive series planned on Palearctic Microlepidoptera (including Pyralidae). The expertise of Dr. Diakonoff, particularly in Tortricidae, provides a welcome coverage for the included species. This is especially true for the previously conglomerated assortment of species placed in Glyphipterigidae by E. Meyrick and the fact that until recently this classification was followed by most works on the Palearctic fauna. The previous concept of Glyphipterigidae has been considerably altered in the past decade; where Meyrick had over 1,200 species worldwide in one family, we now have four separate families and part of a fifth family for …

Book Review: Evolutionary Biology Of Orthopteroid Insects, Thomas J. Walker

Insecta Mundi

This volume is the proceedings of an international conference on the evolution and phylogeny of Orthopteroidea, held in Siena, Italy, January 1986. The occasion for the conference was the 90th birthday of Dr. Felice Capra, of the Museo di Storia Nutrale di Genova. The proceedings consist of 53 papers, in English, ranging in length from 111 pages (Baccetti) to less than one page of text (Carlberg). Their subject matter is similarly diverse - as one would expect if more than 50 orthopterists were invited to give papers at a conference of this title.

A Checklist Of The Ants Of Wyoming (Hymenoptera: Formicidae), G. C. Wheeler, Jeanette Wheeler

Insecta Mundi

The history of myrmrecology in Wyoming began when Fore1 described a new species, obscuripes in the genus Formica from Green River in 1886, four years before Wyoming Territory became a state. There was a long hiatus until 1932 when Cole cited ten records for Pogonomyrmex occidentalis. Since then a dozen authors have published one to many records each.

During the summers of 1957, 1958, 1961, 1963, 1964,1965 and 1966, while we were still at the University of North Dakota (Grand Forks), we made a dozen field trips into Wyoming to observe and collect ants in 12 of the 23 …

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 …

Preimaginal Development And Reproductive Responses To Temperature In Two Populations Of The Colorado Potato Beetle (Coleoptera: Chrysomelidae), Catherine A. Tauber, Maurice J. Tauber, Brian Gollands, Robert J. Wright, John J. Obrycki

Department of Entomology: Faculty Publications

The pattern of geographical differences in two populations of the Colorado potato beetle, Leptinotarsa decemlineata (Say), suggests that preimaginal developmental responses and imaginal reproductive responses to temperature are under different selective pressures. Immatures from the warm, coastal (Long Island) area developed slightly slower, had slightly higher thermal thresholds for development, and suffered more mortality at low temperature than immatures from cooler, Upstate New York. However, more females from the Long Island population oviposited fertile eggs at lower temperatures than females from the upstate population. The data suggest that early planting dates and/or bivoltinism in the warm coastal area cause significant …

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, …

Use Of Radiography In Behavioral Studies Of Turfgrass-Infesting Scarab Grub Species (Coleoptera: Scarabaeidae), M. G. Villani, Robert J. Wright

Department of Entomology: Faculty Publications

The behavior of turfgrass-infesting scarab grubs in response to soil physical properties may affect the stress that each species exerts on turfgrass and the efficacy of control tactics. To gain a more realistic picture of the events that occur within the soil matrix, we have developed a nondestructive X-ray technique to study soil insect movement and behavior in simulated and natural soil blocks in the laboratory Laboratory studies using this technique were done to determine the effect of some soil physical factors on scarab grub movement patterns. Species-specific differences were demonstrated in the responses of four scarab grub species (Japanese …

Focality And Mobility Of Some Peridomestic Cockroaches In Florida (Dictyoptera: Blattaria), Richard J. Brenner

Entomology Papers from Other Sources

The microhabitat distribution and activities of peridomestic cockroaches were examined (August to October 1985) at three sites in northcentral Florida to assess concentration, immobility, and accessibility of populations. Smokybrown cockroaches, Periplaneta fuliginosa (Serville), and Eurycotis floridana (Walker) accounted for at least 67% of cumulative recaptures at each site. Populations were strongly concentrated in palms, trees with treeholes, woodpiles, and (to a lesser extent) various mulches; salient differences were observed for each species, indicating a partitioning of resources. Recapture rates were high, averaging >62% over all three sites for females of both species; rates were significantly lower for males (P < 0.05), but still averaged >40%. …

Quarantine Disinfestation A Bibliography With Relevance To Ornamental Plant Material, Kevin Seaton, Daryl Joyce

Biosecurity published reports

This bibliography has been compiled as part of a programme to develop new and improved techniques for the insect disinfestation of export cut-flowers and cut-foliage. The objective of the programme is to identify the most effective disinfestation treatments. Suitable treatments should kill insects in the flowers without directly injuring the flowers or reducing their postharvest life.

The bibliography presents references relating to the disinfestation of ornamental material (i.e. cut-flowers, cut-foliage, and potted plants). However, it also includes references on disinfestation of fruit, vegetables, and stored grain where this information has some relevance to the disinfestation of ornamental materials. The bibliography …

Differential Susceptibility Of Japanese Beetle, Oriental Beetle, And European Chafer (Coleoptera: Scarabaeidae) Larvae To Five Soil Insecticides, M. G. Villani, Robert J. Wright, P. B. Baker

Department of Entomology: Faculty Publications

Efficacy of bendiocarb, chlorpyrifos, diazinon, ethoprop, and isofenphos was evaluated against last-instar larvae of European chafer, Rhizotrogus majalis (Razoumowsky), Japanese beetle, Popillia japonica Newman, and Oriental beetle, Anomala orientalis Waterhouse, by incorporating insecticides into soil at one-half New York State recommended rates in a laboratory bioassay. Mortality was assessed at 1, 2, 3, 4, and 5 wk. The experiment was repeated three times with white grubs collected at different times and from different locations in New York. White grub species differed significantly in their response to some of the insecticides; European chafer was generally least susceptible. Diazinon provided high mortality …

Alternation Of Sex Ratio In A Partially Bivoltine Bee., Megachile Rotundata (Hymenoptera: Megachilidae), V. J. Tepedino, F. D. Parker

Entomology Papers from Other Sources

Data on offspring production by the alfalfa leafcutting bee, Megachile rotundata (F.), from three site-years were used to examine predictions of parental investment and sex ratio theory. In northern Utah, spring-emergent adults produce two types of offspring: those that develop directly to the adult stage and emerge in midsummer, and those that develop to the prepupal stage and enter diapause until the following year. For species with this kind of life cycle, it has been hypothesized that spring parents should bias their investment in summer emergent progeny towards females if spring males survive to participate in the summer mating. Results …

Entomogenous Nematodes As Biological Control Agents Of European Chafer And Japanese Beetle (Coleoptera: Scarabaeidae) Larvae Infesting Turfgrass, M. G. Villani, Robert J. Wright

Department of Entomology: Faculty Publications

In laboratory studies, infective juveniles of Steinernema feltiae Filipjev (=Neoaplectana carpocapsae Weiser) (All strain) and Heterorhabditis heliothidis (Khan, Brooks & Hirschmann) were tested for their ability to control third-instar European chafer (EC), Rhizotrogus majalis (Razoumowsky), in soil at rates from 19.4-310.0 nematodes per cm² of soil surface. H. heliothidis provided better control of EC larvae than S. feltiae over the range of rates tested. After 25 d, treatment with H. heliothidis provided 94% control of larvae at the lowest rate tested (19.4 per cm²). In a field test in turf against a mixed population of Japanese beetle, …

Tergissima And Femniterga, New Sister Genera Of Calycopis Scudder And Calystryma Field From The South Central Andes (Lepidoptera: Lycaenidae), Kurt Johnson
