The Risks Posed By Mosquito Ultra-Low Volume Applications To Procambarus Clarkii Production, Timothy Mcnamara

LSU Doctoral Dissertations

Mosquito abatement has received much scrutiny due to concerns about the impacts of control applications on non-target organisms. In Louisiana, a great deal of this concern has come from crawfish farmers claiming mosquito abatement applications have damaged crawfish production. To determine which mosquito abatement practices and products pose a risk to crawfish production, we conducted a series of studies examining mosquito abatement practices in the vicinity of crawfish production fields and the impacts of common mosquito abatement product exposure on crawfish health and production. We found that mosquito ULV applications are the most likely to result in exposure to crawfish …

Acmaeodera Moesta Dugès, 1891 (Coleoptera: Buprestidae), A Poorly Known Species From Mexico, Richard L. Westcott, Jesus Romero-Napoles

Insecta Mundi

Two new state records are reported for the Mexican Acmaeodera moesta Dugès (Coleoptera: Bu­prestidae), a lectotype is designated for it, and clarifying discussion is provided.

According to Westcott (2020) there are 152 described valid species of Acmaeodera Eschscholtz in Mexico. Acmaeodera moesta Dugès (Fig. 1–3) was described from the state of Guanajuato, and it has not since been men­tioned in the literature except for listings in catalogs and checklists. Herein we record it from the states of México (MEX) and San Luis Potosí (SLP), designate a lectotype, and provide a detailed discussion.

Lasioglossum (Dialictus) Semicaeruleum (Cockerell, 1895) (Hymenoptera: Halictidae) In Maryland: A Disjunct Population In Eastern North America?, Eugene J. Scarpulla

Insecta Mundi

Since 2004, three specimens of Lasioglossum (Dialictus) semicaeruleum (Cockerell, 1895) (Hyme­noptera: Halictidae) have been collected in Maryland. Other than three specimens from Wisconsin, there are no additional records of this western United States species known east of the Mississippi River. I document the three Maryland records and offer possible scenarios of how the specimens could have arrived in Mary­land.

Lasioglossum (Dialictus) semicaeruleum (Cockerell, 1895) (Hymenoptera: Halictidae) is an abundant western North American species that ranges from the Canadian Prairie Provinces (Alberta, Manitoba, and Saskatchewan) through the United States west of the Mississippi River (Arizona, California, Colorado, …

Genomics Reveals A New Genus And Species From A Single Female Specimen (Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini: Moncina), Ernst Brockmann, Jing Zhang, Qian Cong, Nick V. Grishin

Insecta Mundi

New taxa in Hesperiidae (Lepidoptera: Papilionoidea) are traditionally proposed after inspection of male genitalia, which largely form the basis for Hesperiidae taxonomy. However, with genomic DNA se­quencing, even a single female specimen can be placed in a phylogenetic context of existing classification and taxonomically assigned with confidence. Genomic sequencing of an unusually patterned Hesperiidae female from San Martin, Peru, characterized by pearly spots outlining an inverted heart pattern on the rust-colored ventral hindwing, reveals that it represents an undescribed genus and species named here as Gemmia buechei Brockmann and Grishin, new genus and new species.

Bee‑Safe Peptidomimetic Acaricides Achieved By Comparative Genomics, Vikas Jindal, Daqi Li, Leslie Catherine Rault, Soheila Fatehi, Rupinder Singh, Moritz Mating, Ye Zou, Ho‑Leung Ng, Krzysztof Kaczmarek, Janusz Zabrocki, Shunhua Gui, Guy Smagghe, Troy D. Anderson, Ronald J. Nachman, Yoonseong Park

Department of Entomology: Faculty Publications

The devastating Varroa mite (Varroa destructor Anderson and Trueman) is an obligatory ectoparasite of the honey bee, contributing to significant colony losses in North America and throughout the world. The limited number of conventional acaricides to reduce Varroa mites and prevent disease in honey bee colonies is challenged with wide-spread resistance and low target-site selectivity. Here, we propose a biorational approach using comparative genomics for the development of honey beesafe and selective acaricides targeting the Varroa mite-specific neuropeptidergic system regulated by proctolin, which is lacking in the honey bee. Proctolin is a highly conserved pentapeptide RYLPT (Arg-Tyr-Leu-Pro-Thr) known to …

Natural Enemies And Biological Control Of Stink Bugs (Hemiptera: Heteroptera) In North America, Blessing Ademokoya, Kacie Athey, John R. Ruberson

Department of Entomology: Faculty Publications

Stink bugs comprise a significant and costly pest complex for numerous crops in the United States, including row crops, vegetables, and tree fruits and nuts. Most management relies on the use of broad-spectrum and disruptive insecticides with high human and environmental risks associated with them. Growing concerns about pesticide resistance in stink bugs are forcing pest managers to explore safer and more sustainable options. Here, we review the diverse suite of natural enemies of stink bugs in the US, noting that the egg and the late nymphal and adult stages of stink bugs are the most commonly attacked by parasitoids, …

Evolving Dynamics Of Aedes-Borne Diseases In Africa: A Cause For Concern, Rosemary Sang, Joel Lutomiah, Edith Chepkorir, David P. Tchouassi

All Peer-Reviewed Publications

Aedes-borne viruses, yellow fever (YF), dengue, Chikungunya and Zika are taking a huge toll on global health as Africa faces re-emergence with potential for massive human catastrophe. Transmission driven by diverse vectors in ecological settings that range from urban to rural and sylvatic habitats with human and nonhuman primate/reservoir activities across such habitats has facilitated virus movement and spillover to susceptible human populations. Approved vaccine exists for YF, although availability for routine and mass vaccination is often constrained. Integrating vector surveillance, understanding disease ecology with rationalised vaccination in high-risk areas (YF) remains important in disease prevention and control. We review …

Classical Biological Of Key Horticultural Pests In Africa: Successes, Challenges, And Opportunities, Samira A. Mohamed, Thomas Dubois, Abdelmutalab Ga Azrag, Shepard Ndlela, Peter Neuenschwander

All Peer-Reviewed Publications

Classical biological control (CBC) is considered a safer and more sustainable alternative for management of alien-invasive species. This review presents recent advances in CBC of key horticultural insect pests using parasitoids in Africa. Several CBC programs have been undertaken targeting different insect pests of both fruits and vegetables, largely yielding outstanding success. Key obstacles impeding CBC and opportunities that could promote CBC in Africa are outlined. Also, very brief highlights on recent scientific and technological advances in modeling, integrative taxonomy and molecular tools, and endosymbionts that relate to CBC are provided.

Infested bell pepper harboring different immature stages of T. leucotreta were subjected to a hot water treatment of 50 ± 0.2 °C for eight different time-points to determine heat …

Biodiversity Of Culicidae (Insecta: Diptera) In The Region Of Khenchela (Northeast Algeria), Imane Halimi, Fatima Zohra Zohra Kara-Toumi, Salim Lebbal, Ruben Bueno Mari, Asma Ghorab, Fairouz Saidi

Journal of Bioresource Management

Mosquitoes are considered as vectors of serious human diseases. The prevention of parasitic and arboviral vector-borne diseases is based mostly on vector control strategies. This control cannot be effective unless a strong knowledge of mosquito biology and distribution in the working area. In this context, and in order to improve the knowledge on the specific diversity of the culicids fauna in the region of Khenchela (northeast of Algeria), an inventory of mosquitoes was carried out for the first time in this region. Larval collection was conducted in various types of habitats through continuous monitoring of seven sites from May 2020 …

Exploring The Relationships Between South Texas Northern Bobwhite Populations And Cecal Worms Via System Dynamics, Nicole J. Traub, Benjamin L. Turner, Leonard A. Brennan, Alan M. Fedynich

National Quail Symposium Proceedings

Community ecology historically focused on plants and free-living organisms; however, problems such as defining habitat boundaries and obtaining adequate sample sizes arise when evaluating such communities. The unique nature of host-helminth systems allows parasite community ecologists to avoid these problems when testing ecological hypotheses. Unlike free-living communities that have artificially constructed boundaries, parasite communities have well-defined unambiguous boundaries within host individuals. Due to the inherently complex and dynamic nature of ecological systems, traditional experimental methods often require expensive, long-term trials beyond investigators’ time and resource budgets. Conversely, a system dynamics approach facilitates learning about such systems via simulation of ecosystem …

Subspecific Designation For The Central Appalachian Mountains Population Of Argynnis (Speyeria) Atlantis (W. H. Edwards), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The population of Argynnis atlantis of the central Appalachian Mountains, primarily on the Allegheny Plateau of West Virginia, has long been recognized by entomologists in the eastern United States as distinct from nominotypical populations of A. atlantis in the northeastern United States and eastern Canada. Larger size is often cited, but actual comparison of wing markings has not been done to date. This study applies RGB color analysis on a series of adults from both regions and looks at potential differences in wing markings which may distinguish them.

Different Gut Microbiomes Of Developmental Stages Of Field-Collected Native And Invasive Western Bean Cutworm, Striacosta Albicosta, In Western Nebraska, Paul A. Ayayee, Austin Currie, Julie A. Peterson

Department of Entomology: Faculty Publications

While insects harbor gut microbial associates that perform various functions for the host, lepidopterans have not been considered as prime examples of having such relationships. The western bean cutworm, Striacosta albicosta (Lepidoptera: Noctuidae), is native to North America and has historically been a significant corn pest in its western distribution. It is currently expanding eastwards and is invasive in these new regions. Using 16S rRNA gene sequencing data, this study focused on characterizing the microbiota associated with field-collected eggs, larvae, adults, and host plant materials of S. albicosta in its native range. The diversity of microbiomes varied significantly among S. …

Parasitisation Of Weaver Ants By A Species Of Smicromorpha Girault (Hymenoptera: Chalcididae: Smicromorphinae) And Unequivocal Evidence Of Its Presence In The Afrotropical Region, Robert S. Copeland, Bethelihem Mekonnen, Gerard Delvare

All Peer-Reviewed Publications

Smicromorpha Girault (Hymenoptera: Chalcididae) is distributed in the old world tropics and subtropics from Australia through New Guinea, Southeast and South Asia. Since its original description in 1913 conclusive evidence of its host has been lacking although it has been collected in association with weaver ants (Oecophylla spp.; Formicidae: Formicinae) either in proximity to ant nests or, on one occasion, reared from one. In this paper we report the presence of Smicromorpha pupae within the gaster of Oecophylla longinoda workers from a nest collected in coastal Kenya. This discovery extends the distribution of Smicromorpha to the Afrotropical Region and demonstrates …

Co-Transcriptomic Analysis Of The Maize–Western Corn Rootworm Interaction, Lise Pingault, Saumik Basu, Neetha N. Vellichirammal, William Paul Williams, Gautam Sarath, Joe Louis

Department of Entomology: Faculty Publications

The Western corn rootworm (WCR; Diabrotica virgifera virgifera) is an economically important belowground pest of maize. Belowground feeding by WCR is damaging because it weakens the roots system, diminishes nutrient uptake, and creates entry points for fungal and bacterial pathogens and increases lodging, all of which can significantly suppress maize yields. Previously, it was demonstrated that belowground herbivory can trigger plant defense responses in the roots and the shoots, thereby impacting intraplant communication. Although several aspects of maize-WCR interactions have been reported, co-transcriptomic remodeling in the plant and insect are yet to be explored. We used a maize genotype, …
