Evaluation Of Host Plant Resistance Against Sunflower Moth, Homoeosoma Electellum(Hulst), In Cultivated Sunflower In Western Nebraska, Dawn M. Sikora

Department of Entomology: Dissertations, Theses, and Student Research

Sunflower moth, Homoeosoma electellum, is a serious pest of oilseed and confection sunflowers. In this study, we determine efficacy of resistance against this pest. Thirty commercial hybrids, inbreds, and varieties of sunflowers were tested in replicated field and laboratory studies. Trait efficacy is determined by pericarp strength by means of physical compression tests and damage to achenes. Initial sunflower entries were planted May 2014 and data collection began in early August 2014. A second season was planted June 2015, with sampling beginning late August the same year.

In 2014, oilseed varieties showed a strength average of 2.71 ± 0.11 N …

Analysis Of Cereal Aphid Feeding Behavior And Transcriptional Responses Underlying Switchgrass–Aphid Interactions, Kyle G. Koch

Department of Entomology: Dissertations, Theses, and Student Research

Switchgrass, Panicum virgatum L., is a perennial warm-season grass that is a model species for the development of bioenergy crops. However, the sustainability of switchgrass as a bioenergy feedstock will require efforts directed at improved biomass yield under a variety of stress factors. The objectives of this research were to: (1) elucidate greenbug and yellow sugarcane aphid feeding behavior on resistant and susceptible switchgrasses using electronic penetration graphs (EPG), (2) define transcriptional changes before and during insect feeding through RNA-seq to identify candidate resistance genes in a hybrid switchgrass cultivar, and (3) utilize methods in RNA sequencing of insects to …

Some Corrections And Remarks Regarding The Nomenclature Of Neotropical Athyreini, Passalini, Phanaeini, Rutelini, Cyclocephalini, Dynastini And Oryctini (Coleoptera: Scarabaeoidea), Auke J. Hielkema

Insecta Mundi

A number of nomenclatural issues regarding Neotropical Scarabaeoidea are addressed. Athyreus soesilae Makhan, 2008 is synonymized with Neoathyreus (Neoathyreus) excavatus (Laporte, 1840) (Geotrupidae: Bolboceratinae: Athyreini). Scalmus Zang, 1905 is replaced with its senior synonym Neleuops Kuwert, 1891, nec Neleurops Kuwert, 1891, and the four species it presently contains are thus transferred to Neleuops (Passalidae: Passalinae: Passalini). The spelling of the name Oxysternon oberthueri Olsoufieff, 1924, a junior synonym of Oxysternon (Oxysternon) conspicillatum (Weber, 1801), is fixed (Scarabaeidae: Scarabaeinae: Phanaeini). The year of description of Oxysternon (Oxysternon) festivum (Linnaeus, 1758) is corrected, its existing lectotype invalidated, and a new lectotype designated …

Honey Bee Gut Dysbiosis: A Novel Context Of Disease Ecology, Kirk E. Anderson, Vincent A. Ricigliano

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The honey bee microbiota has become a hot-spot of recent research. Highly co-evolved with its host, the hindgut microbiota of a worker honey bee consists of six bacterial species shown to occur reliably in particular proportions. Altered microbiota structure is associated with host deficiencies, and a variety of bacteria found throughout the hive environment can dominate the worker gut suppressing or displacing microbiota function. The synthesis presented here suggests environmental insults alter gut bacterial balance, leading to decreased host function and disease progression. Specific functional groups of native bacteria represent a model system to investigate dysbiosis and the evolution of …

Cross-Resistance And Synergism Bioassays Suggest Multiple Mechanisms Of Pyrethroid Resistance In Western Corn Rootworm Populations, Adriano E. Pereira, Dariane Souza, Sarah N. Zukoff, Lance J. Meinke, Blair D. Siegfried

Department of Entomology: Faculty Publications

Recently, resistance to the pyrethroid bifenthrin was detected and confirmed in field populations of western corn rootworm, Diabrotica virgifera virgifera LeConte from southwestern areas of Nebraska and Kansas. As a first step to understand potential mechanisms of resistance, the objectives of this study were i) to assess adult mortality at diagnostic concentration- LC99 to the pyrethroids bifenthrin and tefluthrin as well as DDT, ii) estimate adult and larval susceptibility to the same compounds as well as the organophosphate methyl-parathion, and iii) perform synergism experiments with piperonyl butoxide (PBO) (P450 inhibitor) and S,S,S-tributyl-phosphorotrithioate (DEF) (esterase inhibitor) in field populations.

Intraguild Interactions And Behavior Of Spodoptera Frugiperda And Helicoverpa, José P. F. Bentivenha, Débora Goulart Montezano, Thomas E. Hunt, Edson L. L. Baldin, Julie A. Peterson, Vinicius S. Victor, Luiz E. R. Pannuti, Ana María Vélez, Silvana L. Vieira De Paula Moraes

Department of Entomology: Faculty Publications

Background: Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is one of the major pests of maize, and is in the same feeding guild of the noctuid pests, Helicoverpa zea (Boddie), and H. armigera (Hübner), recently reported in South and North America. The intraguild interactions of these species were assessed in laboratory and field conditions by determining the survival of larvae in interactions scenarios with non-Bt maize silks and ears. Moreover, a video-tracking system was utilized to evaluate behavioral parameters during larval interactions in scenarios with or without food.

Results: In intraguild interactions, S. frugiperda had greater survival (55 …

Characteristics of these species are briefly given and illustrative photographs and information on their distribution and hosts are provided.

First Reports Of Non-Phytophagous Nearctic Chrysaugine Moths (Lepidoptera: Pyralidae), James E. Hayden, Lyle J. Buss, Kyle E. Schnepp, Lei Xiao

Insecta Mundi

Coprophagy and probable saprophagy are reported for larvae of two species of chrysaugine moths (Lepidoptera: Pyralidae). Larvae of Parachma ochracealis Walker are found in rotten pine wood and mulch in North-Central Florida. Larvae of Basacallis tarachodes (Dyar) inhabit feces of an unidentifi ed small mammal in a cave in Central Florida and seem to be troglophilic. These behaviors are compared to similar ones in Neotropical chrysaugines such as Humiphila Becker and Cryptoses Dyar. Saprophagy and coprophagy are predicted to be more general habits among Chrysauginae.

First Record Of The Enigmatic Tribe Anaeomorphini (Lepidoptera, Nymphalidae, Charaxinae) Outside Of The Amazon Basin: A New Species Of Anaeomorpha Rothschild, 1894, From The Chocó Region Of Western Ecuador, Keith R. Willmott, Mark J. Simon, Elena Ortiz-Acevedo, Jason P. W. Hall

Case 3733 – Cetonia Marmorea Olivier, 1789 (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini): Proposed Conservation By Reversal Of Precedence With Scarabaeus Pulcher Swederus, 1787, Brett C. Ratcliffe

Department of Entomology: Faculty Publications

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used name Gymnetis marmorea (Olivier, 1789), a flower chafer (Scarabaeidae: Cetoniinae) from Trinidad and Tobago, West Indies, which is threatened by the unused senior subjective synonym Scarabaeus pulcher Swederus, 1787. The head of the holotype of Scarabaeus pulcher Swederus, 1787 is excluded from the holotype under Article 73.1.5 of the Code since it is a piece belonging to a Cotinis Burmeister glued to the body of a Gymnetis MacLeay.
