Observations On The Oak Twig Pruner, Anelaphus Villosus (Coleoptera: Cerambycidae), In Michigan: Size Of Twigs Pruned, Insect Survival, And Seasonality Of Twig Drop, Robert A. Haack

The Great Lakes Entomologist

The oak twig pruner [OTP; Anelaphus villosus (Fabricius)] is likely a species complex, with A. parallelus (Newman) recently recognized as a synonym. The parallelus form of A. villosus is considered the subject of this paper. In Michigan, OTP has a 2-year life cycle, with twigs pruned primarily in even-numbered years and adults emerging from the fallen twigs in odd-numbered years. During 1990 to 2011, I studied various aspects of OTP life history in southern Michigan (Ingham County). Based on measurements from over 300 infested oak twigs, they averaged 43.1 cm long, 9.4 mm in diameter at the pruned end, …

Flies Associated With Floral Canopies Of The New Oilseed Crop, Pennycress, In The Midwestern U.S.A., Frank Forcella, Matt Petersen, William L. Perry, Samantha S. Wells, Alex Hard, Russ W. Gesch, Yesuf Mohammed, Cody Hoerning, Tad L. Wesley, Emma Ambrosi, Winthrop B. Phippen

The Great Lakes Entomologist

Flies are frequent visitors to flowers of many species of plants within the mustard family (Brassicaceae). They derive nutrition from these flowers, and some fly species are pollinators. Field pennycress (Thlaspi arvense) is a mustard species that is being developed as a new “cash cover crop,” i.e., an autumn-sown cover crop whose oil-rich seeds can be harvested profitably in spring. Although pennycress is largely wind- and self-pollinated, its flowers also attract insect visitors. However, the extent of visitation to pennycress flowers by flies remains largely unknown, especially the identities of those flies. Thus, we examined flies associated with …

The Heteroptera (Hemiptera) Of North Dakota Ii: Enicocephalomorpha : Enicocephalidae, Alexander H. Knudson, Veronica Calles Torrez, David A. Rider

The Great Lakes Entomologist

The Enicocephalomorpha of North Dakota is documented with the report of the unique-headed bug, Systelloderes biceps (Say, 1832) from North Dakota for the first time. We also discuss the geographic distribution of S. biceps and Systelloderes culicis (Uhler, 1892), provide color photographs, provide diagnoses for the separation of these species from all other North American species, and designate a lectotype for S. culicis (Uhler).

Feeding Behavior Of Sweet Potato Weevil, Cylas Formicarius (Fabricius) (Coleoptera: Brentidae) On Three Sweet Potato, Ipomoea Batatas L. Cultivars Grown In Tarlac, Philippines, Jerah Mystica Novenario, Flor Ceballo-Alcantara

The Philippine Agricultural Scientist

Sweet potato is grown in tropical countries for its edible tubers, which have become an essential food source. It is usually propagated through vine-cutting, which can be obtained from harvested plants or nurseries intended for cutting production only. The recurrent use of vines may cause increased weevil infestation. The crop is known to be infested with insect pests. More importantly, the sweet potato weevil, Cylas formicarius, targets the tubers, thus, causing the economic losses. Sweet potato farmers in Tarlac claim that only one sweet potato cultivar is being attacked by C. formicarius, however, it was found in this experiment that …

Taxonomy Of Cassava (Manihot Esculenta Crantz) Mealybugs (Hemiptera: Pseudococcidae) - 1: Identification And Local Distribution Of The Predominant Species On Witches’ Broom-Diseased Plants In The Philippines, Ireneo L. Lit Jr., Cristian Lucañas, Joanne Langres, Lolita Dolores, Ruby Ana Laude, Merdelyn Caasi-Lit

The Philippine Agricultural Scientist

Samples of cassava (Manihot esculenta Crantz) plants infected with witches’ broom disease were gathered from 13 provinces in the Philippines. Mealybugs were observed to occur in nine out of the 13 cumulative samples. The most predominant among several mealybug species observed was identified as Pseudococcus jackbeardsleyi Gimpel and Miller. P. jackbeardsleyi is not yet known to transmit phytoplasma, especially the one causing cassava witches’ broom (CWB). However, its occurrence in almost 70% of the CWB-infected samples provides circumstantial evidence that it may be related to the spread of the pathogen. This formal report of identification is in support of the …

Taxonomic Advances Driven By The Genomic Analysis Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

This study presents new findings based on a large-scale analysis of butterfly genomic sequences. Focusing on species identification through comparative genomics, we define subspecies as populations differentiated to a lesser extent than distinct species ("species in the making"). Additionally, we propose further adjustments to the current butterfly classification. As a result, 3 subgenera, 12 species, and 4 subspecies are described as new. New subgenera are (type species in parenthesis): Hyalaus Grishin, subgen. n. (Papilio epidaus E. Doubleday, 1846) of Eurytides Hübner, [1821] (Papilionidae Latreille, [1802]) and Astria Grishin, subgen. n. (Lycaena astraea Freyer, 1851) of Glaucopsyche Scudder, 1872 …

Contrasting Tick Species Behaviors: A Course-Based Undergraduate Research Experience (Cure), Sara Benham, Shovan Dutta, Rohan Maddamsetti, Clayton Wright, Alena Anderson, David T. Gauthier, Holly D. Gaff

Spora: A Journal of Biomathematics

Tick-borne diseases are on the rise throughout the world, and there is a need to better understand tick behavior in order to identify potential new interventions. Ticks have a complex life history and can survive months off-host. There is a lack of large-scale data on off-host tick behavior, which leaves a gap in understanding of tick biology outside of tick-host interactions. Introducing undergraduate students to authentic research early in their studies can help prepare them for independent inquiry in upper-level classes. To address the student needs and fill gaps in tick research, students in introductory biology courses recorded observations of …

Eristalis Tenax Movement Behavior In Response To Light, Temperature, And Food, Jeffery J. Zheng, Zdena M. Janderova, Jason D. Lang

Georgia Journal of Science

Drone flies, Eristalis tenax (Diptera: Syrphidae), are important generalist pollinators and visit flowers globally that range widely in color. The flies’ photoreceptors allow them to sense light wavelengths between 300-600 nm and E. tenax exhibit a positive phototactic response. To understand the effects of light on E. tenax movement, we conducted two-choice behavioral tests to determine their phototactic response to different wavelengths of light across the spectrum (ultraviolet to red light, plus full spectrum white light). The drone flies moved most and quickest toward sunlight, with almost twice the percentage of flies moving toward sunlight than toward black and …

Plum Curculio (Conotrachelus Nenuphar), Kate V. Richardson, Marion Murray

All Current Publications

Plum curculio is a brown weevil (beetle with a snout) native to eastern North America, where it is a major pest of pome and stone fruits. It was detected in Box Elder County, Utah, in the early 1980s, and this population remains the only known infestation in western North America, where it is occasionally found in residential and wild fruit trees. Plum curculio is a quarantine pest in western North America (U.S. and Canada), and fruit grown in infested counties is restricted from being exported. Thus, it is a threat to Utah’s fruit industry and requires ongoing monitoring and management …

Diapause Induction In Eastern North American Populations Of Propylea Quatuordecimpunctata And Hippodamia Variegata (Coleoptera: Coccinellidae), John J. Obrycki

Lady Beetle Research Data

Experiments examined the effect of photoperiod on the expression of adult diapause in North American populations of two Palearctic ladybird beetle species, Propylea quatuordecimpunctata and Hippodamia variegata.

Comparative data for the reproductive responses to different photoperiod conditions for H. variegata were taken from Obrycki (2018). Additionally, comparisons of responses to the four photoperiods between P. quatuordecimpunctata from Jefferson County, NY, USA to P. quatuordecimpunctata from Montreal, Quebec, Canada were also conducted. Data for the Montreal, Quebec, Canada population are from Obrycki et al., (1993).

Two Data sets are included:

(1) Pre-oviposition period (days) as a measure of induction and …

Checklist And Key To The Millipede Species Of Georgia, United States, With Notes On Distribution, Lance Andrew, Bruce Snyder

Graduate Research Showcase

Millipedes are an exceptionally diverse class of animals that have an impact on soil structure and nutrient cycling. Despite their abundance, importance, and wide distribution, they are understudied compared to other animal taxa, and biogeographical information is scant. Georgia, though the largest state by land area east of the Mississippi River, has largely been overlooked by regional millipede checklists. Without baseline species distributions and abundances to inform wildlife management decisions, sufficient measures cannot be taken to preserve millipede biodiversity, especially in light of recent changes in climate and land use. Taxonomic resources for millipede identification in North America are also …

Assessing Endophyte Frequency Distributions And The Effect Of Epichloë Brachyelytri In The Chemotypic And Genotypic Diversity Of Brachyelytrum Erectum, Rachel Ann Sneed

Theses and Dissertations--Plant Pathology

Seed-transmissible epichloid fungal endophytes are best known for their roles as defensive mutualists in cool-season grasses. Historically, the discovery of fungal endophytes was driven by investigations of plant toxicity to livestock, followed by extensive study of their alkaloids and protection against insects and nematodes. Epichloae can produce four classes of alkaloids: ergot alkaloids, lolines (saturated aminopyrrolizidines), indole–diterpenes, and peramine. It is increasingly evident that these hereditary symbionts have much more diverse chemical profiles both in individual populations and between them. To this end, differences in chemotypic profiles of these symbionts may translate to different evolutionary and environmental advantages across plant …

Analysis Of Pepsis Basifusca Lucas (Hymenoptera: Pompilidae: Pepsinae) Taxonomy, Morphology, Biogeography, And Potential Host Spider, Frank E. Kurczewski

Insecta Mundi

A first-time analysis of taxonomically relevant characters, functional morphology, geographic distribution, ecoregion preference, and hypothetical host spiders of Pepsis basifusca Lucas (Hymenoptera: Pompilidae: Pepsinae) is presented. This analysis is compared with other Nearctic species in Vardy’s (2005) Pepsis menechma species-group, particularly P. cerberus Lucas and P. elegans Lepeletier which are suspected parasitoids of trapdoor spiders. Pepsis basifusca females differ from females of these species in possessing a rounded gena-postgena in dorsal view; straight mid and hind tibial spurs; short hind tibial inner spur; and short, very stout, and backward slanted hind tibial bristles. Pepsis basifusca Level III Ecoregions …
