Effect Of A Near-Zero Magnetic Field On Development And Flight Of Oriental Armyworm (Mythimna Separata), 2021 Chinese Academy of Agricultural Sciences
Effect Of A Near-Zero Magnetic Field On Development And Flight Of Oriental Armyworm (Mythimna Separata), Meng-Meng Yan, Lei Zhang, Yun-Xia Cheng, Thomas W. Sappington, Wei-Dong Pan, Xing-Fu Jiang
The geomagnetic field affects all living organisms on the Earth. In this study we investigated the developmental and behavioral effects of rearing Mythimna separata in a near-zero magnetic field (<500 nT) compared to the local geomagnetic field (approximately 50 µT). The near-zero magnetic field produced by a Helmholtz coil system significantly lengthened larval and pupal development durations, increased male longevity, and reduced pupal weight, female reproduction, and the relative expression level of the vitellogenin (Vg) gene in newly emerged females. Moreover, the near-zero magnetic field had a considerable negative effect on the mating ratio of M. separata adults. In addition, the moths in the near-zero magnetic field displayed less flight activity late in the night than those in the Earth's normal geomagnetic field, indicating that the flight rhythm of M. separata may be affected by the near-zero magnetic field. Reduction in magnetic field intensity may have negative effects on the development and flight of oriental armyworm, with consequent additional effects on its migration.

Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, 2021 Southern Adventist University
Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, Hayeong Woo
Campus Research Day
Harvester ants have an interesting behavior of bone collecting. Therefore, harvester ant nests that are positioned around the fossil sites contain various fossil fragments. If there is a statistically significant correlation between the abundance of fossil fragments and the distance of the ant nests from the main fossil sites, ant nests can potentially be used to predict the proximity of the main fossil sites.

A Catalogue Of The Cybocephalidae (Coleoptera: Cucujoidea) Of The World, 2021 Florida State Collection of Arthropods
A Catalogue Of The Cybocephalidae (Coleoptera: Cucujoidea) Of The World, Trevor Randall Smith
A world catalogue and bibliography of the family Cybocephalidae (Coleoptera) is presented. The catalogue contains 207 species within 16 genera. Each taxon is accompanied by a complete taxonomic history, including a full annotated synonymy with original references cited. The reversal of the recent synonymy of Cybocephalus brevis Grouvelle over Cybocephalus minimus Grouvelle is proposed. Cybocephalus aeneus Reiche is removed from synonymy with Cybocephalus micans Reitter and considered incertae sedis.
The Cybocephalidae are a family of small predatory beetles found throughout the world (Smith 2020). While cybocephalids are typically extremely convex, shiny and dark in coloration, the defining characteristic of ...
The Strange Case Of Colophotia Miranda Olivier, 1886 (Coleoptera: Lampyridae: Luciolinae), 2021 Charles Sturt University
The Strange Case Of Colophotia Miranda Olivier, 1886 (Coleoptera: Lampyridae: Luciolinae), Lesley Ballantyne, Wan F.A. Jusoh
A single male specimen identified as Colophotia miranda Olivier (Coleoptera: Lampyridae: Luciolinae) by Blair and housed in the Natural History Museum, London, is redescribed, and its identification and affinities explored.
Ernest Olivier, who first described Colophotia miranda in 1886, was then curator of insects at the Muséum nationale d’Histoire naturelle, Paris (MNHN). Effectively for lampyridologists he was the first in a narrow line of firefly taxonomists. Thanks to Olivier we have our first subfamily classifications, keys, catalogues and species descriptions; work that has undergone much revision and expansion in the last 100 years.

Protura (Arthropoda: Hexapoda) In Slovenian Caves, 2021 Genoa University, Italy
Protura (Arthropoda: Hexapoda) In Slovenian Caves, Loris Galli, Franc Janžekovič, Peter Kozel, Tone Novak
International Journal of Speleology
Protura is a small class of Hexapoda, generally poorly known, and rather scarce data on its occurrence in caves are scattered throughout literature on fauna in caves and in some papers on Protura. Although the cave-dwelling fauna is relatively well studied in Slovenia, published records on Protura are rare. In this paper, data on the occurrence and abundance of Protura in Slovenian caves are considered. Various statistical analyses were performed to compare caves with Protura to those without in 60 intensively monitored cavities to detect any differences in the selected environmental conditions. No significant difference was obtained. Samples collected from ...

Microhabitat Selection Of A Sicilian Subterranean Woodlouse And Its Implications For Cave Management, Giuseppe Nicolosi, Stefano Mammola, Salvatore Costanzo, Giorgio Sabella, Rosolino Cirrincione, Giovanni Signorello, Marco Isaia
International Journal of Speleology
Human activities in subterranean environments can affect different ecosystem components, including the resident fauna. Subterranean terrestrial invertebrates are particularly sensitive to environmental change, especially microclimatic variations. For instance, microclimate modifications caused by the visitors may directly affect local fauna in caves opened to the public. However, since numerous factors act synergistically in modulating the distribution and abundance of subterranean species, it remains challenging to differentiate the impact of human intervention from that of other factors. Therefore, evidence of the impact of tourism on cave invertebrate fauna remains scarce. Over a year and with approximately two visits a month, we investigated ...

The Importance Of Time And Place: Nutrient Composition And Utilization Of Seasonal Pollens By European Honey Bees (Apis Mellifera L.), Gloria Degrandi-Hoffman, Vanessa Corby-Harris, Mark Carroll, Amy L. Toth, Stephanie Gage, Emily Watkins Dejong, Henry Graham, Mona Chambers, Charlotte Meador, Bethany Obernesser
Honey bee colonies have a yearly cycle that is supported nutritionally by the seasonal progression of flowering plants. In the spring, colonies grow by rearing brood, but in the fall, brood rearing declines in preparation for overwintering. Depending on where colonies are located, the yearly cycle can differ especially in overwintering activities. In temperate climates of Europe and North America, colonies reduce or end brood rearing in the fall while in warmer climates bees can rear brood and forage throughout the year. To test the hypothesis that nutrients available in seasonal pollens and honey bee responses to them can differ ...

The evolution of insect resistance to insecticides is frequently associated with overexpression of one or more cytochrome P450 enzyme genes. Although overexpression of CYP450 genes is a well-known mechanism of insecticide resistance, the underlying regulatory mechanisms are poorly understood. Here we uncovered the mechanisms of overexpression of the P450 gene, CYP321A8 in a major pest insect, Spodoptera exigua that is resistant to multiple insecticides. CYP321A8 confers resistance to organophosphate (chlorpyrifos) and pyrethroid (cypermethrin and deltamethrin) insecticides in this insect. Constitutive upregulation of transcription factors CncC/Maf are partially responsible for upregulated expression of CYP321A8 in the resistant strain. Reporter gene ...

Entomology Faculty Publications
Glycyrrhiza, a genus of perennial medicinal herbs, has been traditionally used to treat human diseases, including respiratory disorders. Functional analysis of genes involved in the synthesis, accumulation, and degradation of bioactive compounds in these medicinal plants requires accurate measurement of their expression profiles. Reverse transcription quantitative real-time PCR (RT-qPCR) is a primary tool, which requires stably expressed reference genes to serve as the internal references to normalize the target gene expression. In this study, the stability of 14 candidate reference genes from the two congeneric species G. uralensis and G. inflata, including ACT, CAC, CYP, DNAJ, DREB, EF1, RAN, TIF1 ...
De Novo Whole Genome Assembly Of The Swede Midge (Contarinia Nasturtii), A Specialist Of Brassicaceae, Using Linked-Read Sequencing, 2021 University of Alberta, Canada
De Novo Whole Genome Assembly Of The Swede Midge (Contarinia Nasturtii), A Specialist Of Brassicaceae, Using Linked-Read Sequencing, Boyd A. Mori, Cathy Coutu, Yolanda H. Chen, Erin O. Campbell, Julian R. Dupuis, Martin A. Erlandson, Dwayne D. Hegedus
Entomology Faculty Publications
The swede midge, Contarinia nasturtii, is a cecidomyiid fly that feeds specifically on plants within the Brassicaceae. Plants in this family employ a glucosinolate-myrosinase defense system, which can be highly toxic to non-specialist feeders. Feeding by C. nasturtii larvae induces gall formation, which can cause substantial yield losses thus making it a significant agricultural pest. A lack of genomic resources, in particular a reference genome, has limited deciphering the mechanisms underlying glucosinolate tolerance in C. nasturtii, which is of particular importance for managing this species. Here, we present an annotated, scaffolded reference genome of C. nasturtii using linked-read sequencing from ...

A Brief Review Of The New World Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) With Description Of A New Species From The Southwestern Usa, William B. Warner
New World species of the histerid beetle genus Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) are reviewed, and X. skelleyi, new species, is described. A dichotomous key and illustrations are provided as identification means for the now five included species from the Western Hemisphere.
Xestipyge was erected by Marseul (1862) as a monotypic subgenus of his genus Carcinops for “Carcinops radula Marseul” because of its unusual elytral striae, with fourth dorsal stria arched over the fifth dorsal stria and connecting to the sutural (= sixth dorsal) stria. Lewis elevated Xestipyge to generic status in 1905. In addition to the different elytral ...
