Death Scene Insect Succession In Nebraska: A Guidebook, Erin Bauer, Larry Barksdale, Emma Sidel, Justine Laviolette

Faculty Publications: Department of Entomology

Insect behavior can be helpful to law enforcement in determining time of death, manner of death, location, and environment related to human or other animal victims found at a death scene. They may also provide clues about other aspects associated with an investigation (i.e., fly specks, suspect DNA). The study of how insects and related arthropods can aid in legal investigations is known as forensic entomology. Although this includes both civil applications, such as urban (i.e., maggots in mortuaries or insect structural damage) or stored product (i.e., illness from food contamination) entomology, this manual focuses on criminal ...

Structure And Parasitism Of Egg-Batches Of The Pine Processionary Moth, Thaumetopoea Pityocampa In The Algerian Cedar Forests., Zineb Messaadia, Nabil Bertella, Naama Frah

Journal of Bioresource Management

Today, climate change is one of the greatest threats facing forest ecosystems. It directly influences the geographical distribution of insects and increases epidemics of harmful insects. The present work took place in this context. It aimed to contribute to the knowledge of egg parasitoids that could affect the evolution of the pine processionary caterpillar Thaumetopoea pityocampa, a major forest pest in Algeria and Mediterranean countries. The study was carried out on 120 batches of eggs taken from the Atlas cedar at two sites in the Chelia cedar zone (case of eastern Algeria) in 2017. It allowed the analysis of a ...

Ardella Magnaemirabilis (Coleoptera: Scarabaeidae: Melolonthinae: Ardellini), A New Scarabaeoid Species, Genus And Tribe From The Southwestern United States, M. J. Paulsen

Insecta Mundi

An interesting new taxon of scarabaeoid beetle is described from western Texas, USA. The remark­ably small chafer, Ardella magnaemirabilis new genus, new species (Coleoptera: Scarabaeidae: Melolonthinae: Ardellini) is described and compared to other diminutive scarabaeoid genera from drier habitats of the southwestern USA. The tribe Ardellini, new tribe, is erected to accommodate the unusual genus.

After a few centuries with entomologists scouring the continent, the discovery of unknown Nearctic scarab gen­era is no longer commonplace. The western United States, in particular, is biogeographically diverse with pockets of endemism that makes such discoveries still possible, driving collectors to continue ...

Occurrence Of An Exotic Whitefly, Siphoninus Phillyreae (Haliday) (Hemiptera: Aleyrodidae) In South Korea And Its Potential Pathway Analysis, Seon Woo Lee, Hyun Jik Lee, Jun-Ran Kim, Soo-Jung Suh 2021 Plant Pest Control Division/APQA

Occurrence Of An Exotic Whitefly, Siphoninus Phillyreae (Haliday) (Hemiptera: Aleyrodidae) In South Korea And Its Potential Pathway Analysis, Seon Woo Lee, Hyun Jik Lee, Jun-Ran Kim, Soo-Jung Suh

Insecta Mundi

The ash whitefly, Siphoninus phillyreae (Haliday) (Hemiptera: Aleyrodidae), was first found in southern areas of South Korea during September 2019. During the survey of 2021, no additional specimens of the ash whitefly were found other than the previously reported regions. Attempts to trace a possible path­way for exotic ash whitefly suggested that this species probably followed pathways of illegal importation of infested plants from China or Japan and was unintentionally introduced into South Korea based on a survey-based study. This whitefly has not been intercepted at ports of entry to South Korea on imported plant material between 1999 and ...


Micromentignatha Geberti, A New Tiger Beetle Species From Australia (Coleoptera: Cicindelidae), Jürgen Wiesner 2021 Wolfsburg, Germany

Micromentignatha Geberti, A New Tiger Beetle Species From Australia (Coleoptera: Cicindelidae), Jürgen Wiesner

Insecta Mundi

Micromentignatha geberti (Coleoptera: Cicindelidae), new species, is described. It is distinguished from the other members of the genus by its larger body size and shape of elytral maculation.

Due to the kindness of Christian Kerkering, I was able to study specimens of a tiger beetle species he recently acquired. It proved to be new to science and is described herein. It is a member of Micromentignatha Sumlin, 1981, which raises the number of species in this genus to four (Wiesner 2020: 327). A key to distinguish these congeners as well as a catalog of the genus are given herein.


New Synonymies And Notes In Criodion Audinet-Serville (Coleoptera: Cerambycidae: Cerambycinae), Antonio Santos-Silva, Sergio Devesa 2021 Universidade de Sao Paulo

New Synonymies And Notes In Criodion Audinet-Serville (Coleoptera: Cerambycidae: Cerambycinae), Antonio Santos-Silva, Sergio Devesa

Insecta Mundi

Criodion angustatum Buquet, 1852 and C. pilosum Lucas, 1857 (Coleoptera: Cerambycidae: Cerambycinae) are synonymized with C. tomentosum Audinet-Serville, 1834. The holotypes of C. angustatum and C. hirsutum, and syntypes of C. pilosum and of C. tuberculatum Gahan, 1892 are illustrated for the first time. One of the type localities of C. tuberculatum is corrected.

Currently, Criodion Audinet-Serville, 1834 includes 13 species distributed from Guatemala to southern South America (Monné 2021; Tavakilian and Chevillotte 2021). Despite the relatively small number of species, they encompass several problems with their identification. For example, the specimens often identified as C. murinum Nonfried, 1895 from ...


Phenological And Social Characterization Of Three Lasioglossum (Dialictus) Species Inferred From Long-Term Trapping Collections, Lyllian A.-J. Corbin, David N. Awde, Miriam H. Richards 2021 Brock University, Canada

Phenological And Social Characterization Of Three Lasioglossum (Dialictus) Species Inferred From Long-Term Trapping Collections, Lyllian A.-J. Corbin, David N. Awde, Miriam H. Richards

Entomology Faculty Publications

Detailed social and phenological data collected from nesting aggregations exist for relatively few sweat bee species because nesting aggregations are rarely found in large numbers, even when local populations are highly abundant. This limits researchers’ abilities to assess the social status of many species, which in turn, limits our ability to trace the sequence of evolutionary steps between alternative social states. To address this problem, we demonstrate the utility of rehydrated, pinned specimens from pan trap and netting collections for generating inferences about the phenology and social status of a well-studied sweat bee species, Lasioglossum (Dialictus) laevissimum. A detailed comparison ...


Effects Of A Novel Dsrna-Based Insecticide On The Colorado Potato Beetle, Samuel J. Pallis 2021 University of Maine

Effects Of A Novel Dsrna-Based Insecticide On The Colorado Potato Beetle, Samuel J. Pallis

Electronic Theses and Dissertations

The Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) is one of the most destructive pests of the cultivated potato, Solanum tuberosum. Colorado potato beetles have been devastating potato crops for the past 150 years and have expanded their range during that time, becoming a globally distributed agricultural pest. Potato beetles are well-suited to agricultural environments and have evolved some degree of resistance to virtually all chemical insecticides. As such, the development of novel control methods to both control potato beetle populations and manage the evolution of insecticide resistance are in constant demand

The knockdown of gene functioning through ribonucleic acid ...


Sap Beetles, Nick Volesky, Zachery R. Schrumm, Kalen Taylor 2021 Utah State University

Sap Beetles, Nick Volesky, Zachery R. Schrumm, Kalen Taylor

All Current Publications

Sap beetles are typically considered a secondary pest of corn and overripe fruits and vegetables. They are broadly identified by their small and ovular bodies and club-shaped antennae. Adult sap beetles often feed on corn silk, pollen, and tassels. Larvae feed on kernels inside the husk. This fact sheet reviews how to identify sap beetles and their hosts and damage. It also provides ideas on how to monitor for sap beetles and outlines the options for managing them.

Electrical and Computer Engineering Faculty Publications

Codling moth (CM) (Cydia pomonella L.), a devastating pest, creates a serious issue for apple production and marketing in apple-producing countries. Therefore, effective nondestructive early detection of external and internal defects in CM-infested apples could remarkably prevent postharvest losses and improve the quality of the final product. In this study, near-infrared (NIR) hyperspectral reflectance imaging in the wavelength range of 900–1700 nm was applied to detect CM infestation at the pixel level for three organic apple cultivars, namely Gala, Fuji and Granny Smith. An effective region of interest (ROI) acquisition procedure along with different machine learning and data processing ...

The Effects Of Boric Acid Sugar Bait On Wolbachia Trans-Infected Male Aedes Albopictus (Zap Males®) In Laboratory Conditions, Vindhya S. Aryaprema, Whitney A. Qualls, Karen L. Dobson, Stephen L. Dobson, Rui-De Xue

Entomology Faculty Publications

The field release of Wolbachia trans-infected male mosquitoes, as well as the use of toxic sugar baits, is a novel and promising candidate technique for integrated mosquito management programs. However, the methods of action of the two techniques may not be complementary, because the Wolbachia method releases mosquitoes into the environment expecting a wild population reduction in subsequent generations while the toxic baits are intended to reduce the wild population by killing mosquitoes. This laboratory study was conducted to evaluate the effectiveness of boric acid toxic sugar baits on Wolbachia trans-infected male Aedes albopictus, relative to wild-type Ae. albopictus males ...

Systematics And Population Structure Of Amblyomma Maculatum Group Ticks And Rickettsia Parkeri, An Emerging Human Pathogen In Southern Arizona, Usa, Michelle E.J. E Allerdice

Theses and Dissertations

The recent discovery of Amblyomma maculatum sensu lato (s. l.) ticks in southern Arizona has renewed discussions around species designations for members of the Amblyomma maculatum tick group. Amblyomma maculatum s. l. from Arizona appear to be morphologically intermediate between A. maculatum sensu stricto (s. s.) and A. triste s. s. At present there is no conclusive species designation for the ticks from Arizona. My research focused on analyzing the systematics of both A. maculatum s. l. and Rickettsia parkeri, a common bacterial pathogen transmitted by these ticks.

In the laboratory, A. maculatum s. l. from Arizona and A. maculatum ...

Human Skin Triglycerides Prevent Bed Bug (Cimex Lectularius L.) Arrestment, Sudip Gaire, Zachary C. Devries, Russell Mick, Richard G. Santangelo, Grazia Bottillo, Emanuela Camera, Coby Schal

Entomology Faculty Publications

Bed bugs (Cimex lectularius) have proliferated globally and have become one of the most challenging pests to control indoors. They are nocturnal and use multiple sensory cues to detect and orient towards their human hosts. After feeding, usually on a sleeping human, they return to a shelter on or around the sleeping surface, but not directly on the host. We hypothesized that although human skin odors attract hungry bed bugs, human skin compounds may also prevent arrestment on hosts. We used arrestment assays to test human skin swabs, extracts from human skin swabs, and pure compounds identified from human skin ...


Validation Of Reference Genes For Quantitative Pcr In The Forest Pest, Ips Calligraphus, Mary Wallace, Lynne K. Rieske 2021 University of Kentucky

Validation Of Reference Genes For Quantitative Pcr In The Forest Pest, Ips Calligraphus, Mary Wallace, Lynne K. Rieske

Entomology Faculty Publications

The six-spined ips, Ips calligraphus, is a North American bark beetle that can exploit most eastern North American Pinus species and can cause mortality. Biotic and abiotic disturbances weaken trees, creating breeding substrate that promotes rapid population growth. Management historically relied on silvicultural practices, but as forests become increasingly stressed, innovative management is needed. Manipulation of the cellular RNA interference (RNAi) pathway to induce gene silencing is an emerging means of insect suppression, and is effective for some bark beetles. Quantitative PCR (qPCR) is a powerful tool for analysis of gene expression, and is essential for examining RNAi. To compare ...

Use Of Attractant And Repellent Semiochemicals To Manage Stable Fly (Stomoxys Calcitrans (L.)) Populations On Pastured Cattle Using A Push-Pull Strategy, Alexander Thomas Lehmann 2021 University of Nebraska-Lincoln

Use Of Attractant And Repellent Semiochemicals To Manage Stable Fly (Stomoxys Calcitrans (L.)) Populations On Pastured Cattle Using A Push-Pull Strategy, Alexander Thomas Lehmann

Dissertations and Student Research in Entomology

Stable flies (Diptera: Muscidae) are major economic pests of pastured cattle. Their feeding activity causes billions of dollars of damage to the cattle industry. This project investigated the management of stable flies on pastured cattle using a novel Push-Pull treatment in field trials. The repellent Push treatment, a hydrogenated coconut oil containing approximately 70% of C8, C10, and C12 fatty acids in a starch-pectin water formulation, was applied to the animals weekly. The Pull component was a stable fly trap augmented with an attractant (m-cresol). Permethrin and untreated controls were used as comparisons. Both permethrin and Push-Pull treatments reduced stable ...
