Impact Of Area-Wide And Localized Mosquito Adulticide On Insecticide Susceptibility In Populations Of Culex Quinquefasciatus (Diptera: Culicidae) In New Orleans, Louisiana., Erin Rita Cloherty

LSU Doctoral Dissertations

Abstract

Mosquitoes are a public nuisance and can vector pathogen causing diseases that affect both animal and human health. West Nile virus, vectored by Culex quinquefasciatus, the Southern House mosquito, made its entry into Louisiana early in the 21^st century, causing serious morbidity and mortality. Effective use of insecticides can be useful to combat these mosquitoes and reduce transmission of disease, however use of insecticides can lead to insecticide resistance.

The objectives of this study were to: (1) to screen adult Cx. quinquefasciatus throughout Orleans Parish, Louisiana for insecticide resistance and explore target-site and metabolic mechanisms of resistance, (2) …

Integrated Pest Management And Behavior Of Stored Grain Beetles, Ethan Doherty

LSU Doctoral Dissertations

The lesser grain borer, Rhyzopertha dominica, and the rice weevil, Sitophilus oryzae, are two of the most destructive pests of stored rice. Their management has relied heavily upon fumigant insecticides. However, amid growing concerns that fumigant-resistant pests are becoming widespread, there is an urgent need for diversified management techniques and integrated pest management. Here, we explored management techniques and the behavior of these beetles. Host plant resistance toward both beetles was evaluated for 13 varieties of rice. We found large differences among varieties for both beetles in all resistance measures. We found that while nutritional components of a …

New State Records For 33 Species Of Round Fungus Beetles, Small Carrion Beetles And Mammal Nest Beetles (Coleoptera: Leiodidae) In Ohio, Usa, Ken D. Karns

Insecta Mundi

New state records for 33 species of Leiodidae (Coleoptera) are reported from Ohio, with the major­ity of records from one locality in the southeastern portion of the state. This doubles the known members of the family in Ohio to 66 species in 20 genera.

As part of an ongoing project through the Ohio Coleopterists Society to obtain records for a future checklist of the beetles of Ohio, the Leiodidae (Coleoptera) present an exceptional case. The family Leiodidae is represented by 38 genera and 382 species in North America north of Mexico (Peck and Newton 2017). In their annotated catalog of …

Taxonomic Review Of The North American Dung Beetle Genus Melanocanthon Halffter, 1958 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini), W. D. Edmonds

Insecta Mundi

This paper presents a taxonomic review of the genus Melanocanthon Halffter, a group of ball-roll­ing (telocoprid) dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) endemic to eastern North America. The genus comprises five species, each keyed, diagnosed, illustrated and presented with information on dis­tribution, relationships, and biology: Melanocanthon punctaticollis (Schaeffer), M. granulifer (Schmidt), M. nigricornis (Say), M. bispinatus (Robinson) and Melanocanthon vulturnus Edmonds, new species.

This paper is a sequel to the recent taxonomic study of Boreocanthon (Edmonds 2022). Melanocanthon and Boreo­canthon are very closely related, distinct phylogenetic lineages with affinities to the pilularius species group of Canthon (Halffter 1961) and the …

Pepsis Elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae)—A Secretive Spider Wasp And Century-Long Conundrum, Frank E. Kurczewski

Insecta Mundi

After 105 years of study and 425 recent natural photographs, the host spider and nesting behavior of Pepsis elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae) remain a mystery. Pepsis elegans is the only species in the large and impressive genus Pepsis Fabricius that lives east of the Mississippi River, mainly in the southern U.S. The other 14 Nearctic Pepsis species inhabit the southern U.S. west of the Mississippi River and northern Mexico. They capture and provision their nests with large, hairy, heavy-bodied, stout-legged tarantulas of the genus Aphonopelma Pocock (Araneae: Mygalomorphae: Theraphosidae), the only native theraphosid genus in this region. There are …

Freshwater Macroinvertebrate Communities In Baldwin County, Georgia, Heath Michael Ghioto, Michelle K. Murdock, Nadya S. Gutierrez, Kristine N. White Ph.D.

Georgia Journal of Science

Freshwater ecosystems are critical habitats for maintaining biodiversity, often providing refuge for organisms especially in urban settings. Baldwin County, GA is home to many freshwater lakes that are part of the Oconee River watershed. Despite ongoing water quality monitoring, aquatic macroinvertebrates are under studied in the area. Aquatic macroinvertebrate diversity of one forested and one residential lake in Milledgeville, GA was documented for the first time. Despite low sample size, community composition was significantly different between lakes, with 27 families in Lake Laurel (forested), 44 families in Lake Oliver Hardy (residential), and only 19 families collected from both lakes. Seasonal …

Hilling As A Cultural Control Strategy For Soybean Gall Midge (Diptera: Cecidomyiidae), Anthony Justin Mcmechan, Joana Schroeder De Souza, Natasha Umezu, Pragya Gupta, Gabriela Inveninato Carmona

Department of Entomology: Faculty Publications

Soybean gall midge, Resseliella maxima Gagné, was recently identified as a new species causing significant injury to soybean and is currently found in 164 counties across 7 midwestern states (NE, IA, SD, MN, MO, ND, and KS). Infestation of soybean begins in late spring, when adults emerge from last year’s soybean field. Infestation of a new soybean crop depends on the presence of fissures which start to form at the base of the soybean plant around the V2 stage. Field observations indicate that these fissures are only present below the cotyledonary nodes or in the area within 3–5 cm above …

Re‑Using Food Resources From Failed Honey Bee (Apis Mellifera L.) Colonies And Their Impact On Colony Queen Rearing Capacity, Rogan Tokach, Autumn H. Smart, Judy Wu-Smart

Department of Entomology: Faculty Publications

For over a decade, beekeepers have experienced high losses of honey bee (Apis mellifera L.) colonies due to a variety of stressors including pesticide exposure. Some of these chemical stressors may residually remain in the colony comb and food resources (pollen and nectar) of failed colonies and be later re-used by beekeepers when splitting and building back new colonies. The practice of re-using comb from previously perished colonies (termed “deadout”) is common in beekeeping practice, but its role in affecting colony health is not well understood. Here, we evaluate the impact of reused, pesticide-contaminated “deadout” combs on colony function …

Examination Of The Status Of Phyciodes Tharos Distincta Bauer, 1975, Confirming It As A Valid Subspecies, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The subspecific status of Phyciodes tharos distincta is reexamined. A specimen series from southern Arizona reveals that distincta shows a distinct, unique phenotype dissimilar from eastern North American nominotypical P. t. tharos. Subspecies distincta occupies a very limited range in extreme southeastern California, southern Arizona, and northwestern Mexico. A lectotype is designated.

First Record Of Paratelenomus Saccharalis (Dodd, 1914) (Hymenoptera: Scelionidae) A Natural Enemy Of The Invasive Species Brachyplatys Subaeneus (Westwood, 1837) (Heteroptera: Plataspidae) In Panama And The Neotropical Region, Jean Carlos Abrego, José A. Rivera, Carelos Vargas H., Annette Garrido, Julio Gutiérrez L., Miguel A. Osorio-Arenas, Pedro A. Arauz L., Luis A. Jaén, Rubén Collantes G., Alonso Santos-Murgas

Paratelenomus saccharalis (Dodd) (Hymenoptera: Scelionidae) parasitizing Brachyplatys subaeneus (Westwood) eggs is reported for the first time for Panama. Brachyplatys subaeneus is an invasive species from Asia and is regarded as an important agricultural pest in the Americas.

The family Plataspidae (Hemiptera: Heteroptera) contains 66 genera and 606 species described (Rider et al. 2018), all distributed in the Old World, with the greatest diversity in Asia and Africa. Within this family, the genus Brachyplatys Boisduval, 1835 (Heteroptera: Plataspidae) has an Asian distribution with about 50 described species. The species Brachyplatys subaeneus (Westwood, 1837) is distributed in the Indo-Malay biogeographic region, being …

Phylogenomics Reveals The History Of Host Use In Mosquitoes, John Soghigian, Charles Sither, Silvia Andrade Justi, Gen Morinaga, Brian K. Cassel, Christopher J. Vitek, Todd Livdahl, Siyang Xia, Andrea Gloria-Soria, Jeffrey R. Powell

School of Integrative Biological & Chemical Sciences Faculty Publications

Mosquitoes have profoundly affected human history and continue to threaten human health through the transmission of a diverse array of pathogens. The phylogeny of mosquitoes has remained poorly characterized due to difficulty in taxonomic sampling and limited availability of genomic data beyond the most important vector species. Here, we used phylogenomic analysis of 709 single copy ortholog groups from 256 mosquito species to produce a strongly supported phylogeny that resolves the position of the major disease vector species and the major mosquito lineages. Our analyses support an origin of mosquitoes in the early Triassic (217 MYA [highest posterior density region: …

Butterfly Classification And Species Discovery Using Genomics, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Genomic sequencing of worldwide butterfly fauna followed by phylogenetic analysis of protein-coding genes informs butterfly classification throughout the taxonomic hierarchy, from families to species. As a rule, we attribute the same taxonomic rank to more prominent clades of comparable divergence (that is, at the same level in the tree). For species delimitation, we use criteria based on relative genetic differentiation and the extent of gene exchange between populations. We analyze the current taxonomic classification of butterflies in the light of genomic phylogenies and encounter clades that correspond to yet unnamed taxa. As a result, 11 tribes, 33 subtribes, 2 genera, …

Needham’S Girls: A Historical Case Study Of Gender And Mentoring In Entomology, Pat Munday

Interdisciplinary Arts and Sciences Articles

James G. Needham (1868-1958) was a professor of entomology at Cornell University from 1906 to 1936, and an active emeritus for about ten years thereafter. As a professor, mentored many women graduate students at Cornell, a group that included twenty-nine who took doctorates. As a scientist, he was a member of an extensive network that included many more women entomologists. These women were located throughout the United States and Canada. Some had been his students at Cornell, some were colleagues with whom he did fieldwork, and others were young women who, even though students at colleges other than Cornell, worked …
