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
Insecta Mundi
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 …
Conservation Risks And Benefits Of Establishing Monarch Butterfly (Danaus Plexippus) Breeding Habitats Close To Maize And Soybean Fields In The North Central United States: A Landscape-Scale Analysis Of The Impact Of Foliar Insecticide On Nonmigratory Monarch Butterfly Populations, 2021 Missouri University of Science and Technology
Conservation Risks And Benefits Of Establishing Monarch Butterfly (Danaus Plexippus) Breeding Habitats Close To Maize And Soybean Fields In The North Central United States: A Landscape-Scale Analysis Of The Impact Of Foliar Insecticide On Nonmigratory Monarch Butterfly Populations, Tyler J. Grant, Niranjana Krishnan, Steven P. Bradbury
Biological Sciences Faculty Research & Creative Works
Establishing habitat in agricultural landscapes of the north central United States is critical to reversing the decline of North America's eastern monarch butterfly (Danaus plexippus) population. Insecticide use could create population sinks and threaten recovery. Discouraging habitat establishment within a 38-m zone around crop fields is a suggested risk mitigation measure. In Story County, Iowa, United States, this mitigation would discourage habitat establishment in 84% of roadsides and 38% of noncrop land. It is unclear if the conservation benefits from establishing habitat close to crop fields outweigh suppression of population growth owing to insecticide exposure. Consequently, monarch conservation …
Stage-Specific Action Of Juvenile Hormone Analogs, 2021 University of Kentucky
Stage-Specific Action Of Juvenile Hormone Analogs, Ramaseshadri Parthasarathy, Subba Reddy Palli
Entomology Faculty Publications
The discovery of juvenile hormones (JH) and their synthetic analogs (JHA) generated excitement and hope that these compounds will replace first- and second-generation insecticides that have not so desirable environmental and human safety profiles. However, JHAs used commercially during the past four decades did not meet these expectations. The recent availability of advanced molecular and histological methods and the discovery of key players involved in JH action provided some insights into the functioning of JHA in a stage and species-specific manner. In this review, we will summarize recent findings and stage-specific action of JHA, focusing on three commercially used JHA, …

Bark- And Wood-Infesting Coleoptera And Associated Parasitoids Reared From Shagbark Hickory (Carya Ovata) And Slippery Elm (Ulmus Rubra) In Ingham County, Michigan, Robert A. Haack
The Great Lakes Entomologist
Ten species of bark- and wood-infesting Coleoptera (borers) and five parasitoid species (Hymenoptera) were reared from shagbark hickory (Carya ovata) branches 1-2 years after tree death, and similarly, seven borers and eight parasitoids were reared from slippery elm (Ulmus rubra) branches one year after tree death in Ingham County, Michigan, in 1986-87. The borers were species of bostrichids, buprestids, cerambycids, and curculionids (including Scolytinae). The parasitoids were braconids, chalcidids, eurytomids, ichneumonids, and pteromalids. One new larval host record was recorded: the cerambycid Urgleptes querci (Fitch), being reared from U. rubra. This paper presents new Michigan …

Sirex Nigricornis (Hymenoptera: Siricidae) Larval Development Correlated With Tree Characteristics And Ophiostomoid Fungal Infection, Jess Hartshorn, Larry D. Galligan, Fred Stephen
The Great Lakes Entomologist
The native North American wood wasp, Sirex nigricornis F., has received significant attention over the last several years due to the introduction and successful establishment of the European wood wasp, S. noctilio L. in eastern North America. Larval size and development of S. nigricornis are important variables that can help to compare demography of the two species and predict future interactions. We measured head capsule width, body length, and weight of S. nigricornis larvae removed from 14 pine trees, felled across the Ozark and Ouachita National Forests of Arkansas in 2012. We also recorded the height at which larvae were …
The Probability Of Spotted Lanternfly, Lycorma Delicatula (Hemiptera: Fulgoridae), Escape Differs Among Life Stages And Between Two Trapping Techniques Commonly Used By Landowners, Sticky Bands And Duct Tape., 2021 West Chester University of Pennsylvania
The Probability Of Spotted Lanternfly, Lycorma Delicatula (Hemiptera: Fulgoridae), Escape Differs Among Life Stages And Between Two Trapping Techniques Commonly Used By Landowners, Sticky Bands And Duct Tape., Matthew Desko, Carolyne Schiebel, Samantha Silverman, Jessica Bickel, Karen Felton, Jennifer L. Chandler
The Great Lakes Entomologist
The invasive Lycorma delicatula (White) was first identified in Pennsylvania, U.S.A. in 2014, and has since increased its range to several Eastern states. Lycorma delicatula pose a serious threat to many native species, including hardwoods and grapes, and land owners are continually seeking effective traps to control populations. Both commercially-produced Web-Cote brand sticky bands and less expensive duct tape are often used by land owners to trap L. delicatula. However, the probability of escape from these adhesives has not been formally assessed, and almost certainly differs as a function of life stage and type of adhesive used. The purpose …

The Great Lakes Entomologist
Abstract
Monitoring tick infestation of wildlife provides baseline tick
occurrence data that may have human or animal health implications. We collected 312 ticks of four species from 5,122 birds of 93 species while monitoring bird migration during 15 fall and spring seasons between 2011 and 2019 in the northern Lower Peninsula of Michigan. Twenty-seven of 93 bird species hosted ticks with an overall prevalence (=at least one tick) of 3.6% (185/5,122). Median burden was one tick/per infested bird with a range of 1-16 ticks per infested bird. Tick species collected were primarily Haemaphysalis leporispalustris (Packard) and Ixodes scapularis Say, with …
Multi-Year Biological Control Of Black Vine Weevil, Otiorhynchus Sulcatus, With Persistent Entomopathogenic Nematodes, 2021 Cornell University
Multi-Year Biological Control Of Black Vine Weevil, Otiorhynchus Sulcatus, With Persistent Entomopathogenic Nematodes, Elson J. Shields, Antonio M. Testa
The Great Lakes Entomologist
Abstract:
The black vine weevil (BVW), Otiorhynchus sulcatus Fabricius (Coleoptera: Curculionidae), has a worldwide distribution and is a serious pest of many agricultural crops with a host plant species range of 140 plants. Common economic losses occur in small fruits, including strawberries, ornamental and nursery plants, caused primarily by the root feeding larvae resulting in reduced vigor and plant death.
The susceptibility of BVW to entomopathogenic nematodes (EPNs) is well established with numerous authors publishing papers using a wide array of EPN species from commercial sources and very high application rates for use as a biopesticide. The concept of using …

The Great Lakes Entomologist
In this note, we report the first Minnesota state records of Osmia (Helicosmia) georgica Cresson 1878,Megachile (Sayapis) inimica Cresson 1872, and Megachile (Sayapis) frugalis Cresson 1872, which were collected in 2018. We also provide the first description of the nest structure of M. frugalis. All three species typically have more southern distributions. The nest of M. frugalis shows similar structure to other species in the subgenus Sayapis Titus, such as M. inimica and M. pugnata, particularly in that the longitudinal nest cell walls lack a lining of leaf pieces, and the cell partitions are made from …

The genome assembly of Anopheles darlingi consists of 2221 scaffolds (N50 = 115,072 bp) and has a size spanning 136.94 Mbp. This assembly represents one of the smallest genomes among Anopheles species. Anopheles darlingi genomic DNA fragments of ~37 Kb were cloned, end-sequenced, and used as probes for fluorescence in situ hybridization (FISH) with salivary gland polytene chromosomes. In total, we mapped nine DNA probes to scaffolds and autosomal arms. Comparative analysis of the An. darlingi scaffolds with homologous sequences of the Anopheles albimanus and Anopheles gambiae genomes identified chromosomal rearrangements among these species. Our results confirmed that physical mapping …

Urban ecosystems are a patchwork of habitats that host a broad diversity of animal species. Insects comprise a large portion of urban biodiversity which includes many pest species, including those that transmit pathogens. Mosquitoes (Diptera: Culicidae) inhabit urban environments and rely on sympatric vertebrate species to complete their life cycles, and in this process transmit pathogens to animals and humans. Given that mosquitoes feed upon vertebrates, they can also act as efficient samplers that facilitate detection of vertebrate species that utilize urban ecosystems. In this study, we analyzed DNA extracted from mosquito blood meals collected temporally in multiple neighborhoods of …

Aphid Endosymbiont Facilitates Virus Transmission By Modulating The Volatile Profile Of Host Plants, 2021 Hunan Academy of Agricultural Sciences, China
Aphid Endosymbiont Facilitates Virus Transmission By Modulating The Volatile Profile Of Host Plants, Xiao-Bin Shi, Shuo Yan, Chi Zhang, Li-Min Zheng, Zhan-Hong Zhang, Shu-E Sun, Yang Gao, Xin-Qiu Tan, De-Yong Zhang, Xuguo Zhou
Entomology Faculty Publications
BACKGROUND: Most plant viruses rely on vectors for their transmission and spread. One of the outstanding biological questions concerning the vector-pathogen-symbiont multi-trophic interactions is the potential involvement of vector symbionts in the virus transmission process. Here, we used a multi-factorial system containing a non-persistent plant virus, cucumber mosaic virus (CMV), its primary vector, green peach aphid, Myzus persicae, and the obligate endosymbiont, Buchnera aphidicola to explore this uncharted territory.
RESULTS: Based on our preliminary research, we hypothesized that aphid endosymbiont B. aphidicola can facilitate CMV transmission by modulating plant volatile profiles. Gene expression analyses demonstrated that CMV infection reduced …
