Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer

Lawrence G. Harshman Publications

Stress resistance is associated with longevity in Drosophila melanogaster and other model organisms used for genetic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life reproduction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control lines. A relative increase in oxidative stress resistance is a correlated response to selection in this laboratory selection experiment. Increased oxidative stress resistance appears to be a relatively robust correlated response to laboratory selection for late-life reproduction and extended longevity.

Biosystematics And Evolution Of The Triatominae = Biossistemática E Evolução De Triatomíneos, Christopher J. Schofield

Harold W. Manter Laboratory of Parasitology: Library Materials

Abstract

In this paper we summarize the systematics of the 130 currently recognized species of Triatominae and the key features of their evolutionary background. There is increasing evidence that the subfamily has polyphyletic origins, with the various tribes and species groups probably arising from different reduviid lineages in relatively recent times.

Resumo

Neste trabalho resume-se a sistemática das 130 espécies de triatomíneos atualmente reconhecidas, com os elementos principais de sua evolução. Existem evidências crescentes para a origem polifilética da subfamília. As diferentes tribos e grupos de espécies que a compõem teriam surgido recentemente, a partir de diferentes linhagens de reduviídeos.

Amplification And Methylation Of An Esterase Gene Associated With Insecticide-Resistance In Greenbugs, Schizaphis Graminum (Rondani) (Homoptera: Aphididae), Midori Ono, Jeffrey J. Swanson, Linda M. Field, Alan L. Devonshire, Blair D. Siegfried

Department of Entomology: Faculty Publications

The greenbug aphid, Schizaphis graminum (Rondani) has developed resistance to organophosphorus insecticides by the over-production of esterases that have been classified as Type I and Type II. The first twenty N-terminal amino acids of the Type I esterase were determined and used to design an oligonucleotide, which in conjunction with an active site primer derived from conserved sequences of other insect esterases and two internal primers specific for esterases from another aphid species resulted in a 0.85 kb genomic DNA fragment from resistant greenbugs. This was extended by 5′ RACE which provided approximately 1.2 kb of the 5′ end …

Oviposition By European Corn Borer (Lepidoptera: Crambidae) In Response To Various Transgenic Corn Events, Richard L. Hellmich, L. S. Higgins, John F. Witkowski, J. E. Campbell, L. C. Lewis

Haskell Agricultural Laboratory (Northeast Research and Extension Center)

Oviposition preference by European corn borers, Ostrinia nubilalis (Hübner), for or against transgenic corn would influence amounts of refuge required for resistance management. The objective of this research was to determine if various Bacillus thuringiensis (Bt) corn transgenic events influence O. nubilalis oviposition. All commercially available events (currently 5) were evaluated, plus 1 experimental event. Results from 3 independent studies are reported, including 3 field-cage experiments with vegetative corn, 2 field-cage experiments with reproductive corn, and 2 field experiments with natural O. nubilalis on reproductive corn. In each case, Bt corn hybrids are compared with their near isogenic hybrids by …

Blissus Occiduus (Hemiptera: Lygaeidae): A Chinch Bug Pest New To Buffalograss Turf, Frederick P. Baxendale, Tiffany Heng-Moss, Terrance P. Riordan

Department of Entomology: Faculty Publications

Blissus occiduus Barber, a relatively small chinch bug characterized by conspicuous wing dimorphism, has emerged as an important insect pest of buffalograss, Buchloe dactylnides (Nuttall) Engelmann. It completes 2 generations a year on buffalograss in Nebraska. Overwintered adults become active as early as mid-March. Depending on the season, 1st-generation nymphs can be present from early May through early August, with 1st-generation adults (up to 60% macropterous forms) appearing in mid to late June. Second generation nymphs can be present from early July through fall, with 2nd-generation adults appearing in late August to early September. These predominately brachypterous (>95%) adults …

Tissue Polyunsaturated Fatty Acids And A Digestive Phospholipase A 3 In The Primary Screwworm, Cochliomyia Hominivorax, A.R. Nor Aliza, R.L. Rana, Steven R. Skoda, Dennis R. Berkebile, David W. Stanley

Department of Entomology: Faculty Publications

We report on the presence of arachidonic acid in larval and adult tissues of the primary screwworm, Cochliomyia hominivorax and of the secondary screwworm, C. macellaria. Arachidonic acid is present in the phospholipids of whole animal extracts of both species. This fatty acid appears to be accumulated during the larval stages, because proportions of arachidonic acid were higher in adults than in larvae. These insects probably obtain the arachidonic acid from dietary phospholipids. We also report on a phospholipase A2 activity in midgut preparations from third instars of the primary screwworm. Phospholipase A2 is responsible for hydrolyzing fatty acids …

Distribution, Ecology, And Population Dynamics Of The American Burying Beetle [Nicrophorus Americanus Olivier (Coleoptera, Silphidae)] In South-Central Nebraska, Usa, Jon C. Bedick, Brett C. Ratcliffe, W. Wyatt Hoback, Leon G. Higley

University of Nebraska State Museum: Entomology Papers

The endangered American burying beetle, Nicrophorus americanus Olivier, was previously widespread throughout eastern North America. In the past century numbers of this beetle have drastically declined and currently remnant populations are known from only six states despite intensive surveying efforts conducted for the last nine years. Efforts aimed at discovering and managing remnant populations have been generally limited by a lack of knowledge concerning N. americanus biology. We used baited pitfall traps to define the range of the Gothenburg, Nebraska, population of N. americanus. Using mark-recapture techniques, we estimate that the annual Gothenburg population consists of more than one …

Taxonomic Status Of Bambusaspis Miliaris, B. Robusta, And B. Pseudomiliaris (Hemiptera: Coccoidea: Asterolecaniidae), C. F. Stumpf, P. L. Lambdin

Insecta Mundi

Based on an assessment of 50 morphological characters from 110 specimens of Bambusaspis miliaris (Boisduval 1869), B. robusta (Green 1908), and B. pseudomiliaris (Green 1922) from different geographic regions around the world, we conclude that these specimens represent the same species. Therefore, the taxa B. robusta and B. pseudomiliaris are considered junior subjective synonyms of B. miliaris.

Acmaeodera Pubiventris Horn (Coleoptera: Buprestidae): A Polytypic Species Or A Superspecies?, Richard L. Wescott

Insecta Mundi

Acmaeodera pubiventris Horn was studied in detail and, without rejecting that it may be a superspecies, I concluded it is a polytypic species comprised of A. p. pubiuentris, A. p. lanata Horn, A. p. yumae Knull-these generally have been considered as full species-and a new subspecies, A. p. panocheae, described herein. It is suggested that A. p. yumae could be a megasubspecies. Detailed comparisons are made, variation is discussed, and biological and distributional data are provided. A. p. lanata is recorded from Mexico (Baja California) for the first time.

All of these have an occipital carina, sometimes most evident ventrally. As a rule there are 2 forewing submarginal cells, but in caledonicus, dolichocara, nigripes, and propodealis there is only one such cell.

Notes On A New Mealybug (Hemiptera: Coccoidea: Pseudococcidae) Pest In Florida And The Caribbean: The Papaya Mealybug, Paracoccus Marginatus Williams And Granara De Willink, Douglass R. Miller, Douglas J. Williams, Avas B. Hamon

Insecta Mundi

Paracoccus marginatus Williams and Granara de Willink, here called the papaya mealybug, was first detected in the United States in Hollywood, Florida in 1998. By the end of 1998 it was found in four localities in the state and has since spread to nine localities in five counties. This mealybug appears to have moved through the Caribbean area since its 1994 detection in the Dominican Republic. The pest is reported to cause serious damage to tropical fruit, especially papaya, and has been detected most frequently, in Florida, on hibiscus. It is now known from Antigua, Belize, the British Virgin Islands, …
