Acute Toxicity Of Atrazine, Alachlor, And Chlorpyrifos Mixtures To Honey Bees, Christopher J. Fellows, Troy D. Anderson, Daniel R. Swale

Department of Entomology: Faculty Publications

The acute toxicity of chlorpyrifos and chlorpyrifos-oxon (organophosphorothioate insecticides) was examined alone and in combination with atrazine (triazine herbicide) and alachlor (chloroacetanilide herbicide) to honey bees (Apis mellifera). Atrazine and alachlor were observed to not be acutely toxic to bees at doses up to 10 and 4 μg per bee, respectively. However, atrazine significantly increased chlorpyrifos toxicity by 3-fold while reducing chlorpyrifos-oxon toxicity by 1.8-fold. These changes in toxicity are correlated with significant 1.3- and 1.2-fold inhibition of acetylcholinesterase (AChE) activity in bees exposed to chlorpyrifos and chlorpyrifos-oxon, respectively. Atrazine significantly increased cytochrome P450, general esterase, and glutathione …

First Host Record, Nesting Behavior, And Taxonomic Position Of The Spider Wasp Genus Hesperopompilus Evans And Some Other Evans Genera (Hymenoptera: Pompilidae), Frank E. Kurczewski, Rick C. West, James P. Pitts

Insecta Mundi

First host record, prey transport, and burrow excavation are described for Hesperopompilus sp., an undescribed, rare spider wasp (Hymenoptera: Pompilidae) from Texas. Taxonomic, ecological, and behav­ioral examination of the genus subsequently led to an investigation of the previously related Perissopompilus Evans and Xerochares Evans. Taxonomic, host preference, nesting behavior, and phylogenomic relationships of the three taxa are discussed along with those of Xenopompilus Evans. The molecular connection of Perisso­pompilus and Allochares Banks is supported by their common use of host species of Filistatidae.

Evans (1951), in his taxonomic study of the spider wasp tribe Pompilini (Hymenoptera: Pompilidae: Pompilinae), described the …

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, …

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.

Erratum To Leblanc (2022): The Dacine Fruit Flies (Diptera: Tephritidae: Dacini) Of Oceania, Luc Leblanc

Insecta Mundi

After publication of Leblanc (2022), it was noticed that the wrong graph was used for the mean (±SE) daily captures of Dacus perpusillus (Drew) in cue-lure traps (Fig. 135). The author and the Insecta Mundi editorial staff apologize for this error. The intended version of Figure 135 is reproduced here. Insecta Mundi has also released a revised version of the Leblanc (2022) manuscript, with this error corrected. However, the revised version is not an official peer-reviewed article, and anyone wishing to reference the findings of Leblanc (2022) should cite the original manuscript or this erratum.

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. …

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, …

Department of Entomology: Faculty Publications

Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates H. zea population dynamics are hierarchically structured with continental-level effects …
