The Puzzling Presence Of Lestes Australis (Odonata: Lestidae) In Wisconsin - Does This Species Migrate?, Robert B. Dubois, Kenneth J. Tennessen Nov 2021

The Puzzling Presence Of Lestes Australis (Odonata: Lestidae) In Wisconsin - Does This Species Migrate?, Robert B. Dubois, Kenneth J. Tennessen

The Great Lakes Entomologist

Lestes disjunctus australis Walker, 1952 was named as a subspecies of Lestes disjunctus Selys, 1862. In recent decades it has been considered deserving of full species status by most specialists. The core of its eastern North American range is south of Wisconsin, but during April through June of some years, mature individuals, and occasionally reproductive behavior, are observed at shallow ponds and wetlands mostly in the southern half of the state. Since first recorded in Wisconsin in 2002, it has been detected in 13 of Wisconsin’s 72 counties. However, there has been no unequivocal documentation of successful reproduction in the …


New Record Of Idana Marginata (Say) (Diptera: Tephritoidea: Ulidiidae) From Wisconsin, Daniel K. Young Nov 2021

New Record Of Idana Marginata (Say) (Diptera: Tephritoidea: Ulidiidae) From Wisconsin, Daniel K. Young

The Great Lakes Entomologist

Idana marginata (Say) was previously known from northeastern North America: Canada and the United States, west to northeastern Illinois and south to North Carolina. Herein, collection events are reported from Richland County in southwestern Wisconsin. This new state record significantly increases the known geographical distribution of the species to the west. The specimens were recovered from an unbaited Lindgren funnel trap during two intervals between 26 June and 28 July 2019.


Bark- And Wood-Infesting Insects (Coleoptera And Hymenoptera) And Associated Parasitoids Reared From Yellow Birch (Betula Alleghaniensis) In Ingham County, Michigan, Robert A. Haack Nov 2021

Bark- And Wood-Infesting Insects (Coleoptera And Hymenoptera) And Associated Parasitoids Reared From Yellow Birch (Betula Alleghaniensis) In Ingham County, Michigan, Robert A. Haack

The Great Lakes Entomologist

Four species of bark- and wood-infesting borers (two Coleoptera and two Hymenoptera) and six parasitoid species (Hymenoptera) were reared from yellow birch (Betula alleghaniensis Britton) one year after the trees were cut and left standing in a woodlot in Ingham County, Michigan in 1986–87. The borers were species of Cerambycidae (Coleoptera) and Xiphydriidae (Hymenoptera), and hymenopteran parasitoid species of Aulacidae, Braconidae, Chalcididae, and Pteromalidae. Xiphydriophagus meyerinckii (Ratzeburg) (Pteromalidae) is a new Michigan state record. For the borers, yellow birch is a new host record for the cerambycid Sternidius alpha (Say) and the xiphydriid Xiphydria tibialis Say. Seasonal emergence data …


Anomalously Pale-Haired Specimens In Three Genera Of Cleptoparasitic Bees (Hymenoptera: Apidae: Nomadinae), Thomas M. Onuferko Nov 2021

Anomalously Pale-Haired Specimens In Three Genera Of Cleptoparasitic Bees (Hymenoptera: Apidae: Nomadinae), Thomas M. Onuferko

The Great Lakes Entomologist

Cases of partially albinic specimens of cleptoparasitic bees (Hymenoptera: Apidae: Nomadinae) in which the pubescence lacks the usual pigmentation are presented and discussed. Anomalously pale-haired individuals within the following three genera are known: Brachymelecta Linsley, Epeolus Latreille, and Triepeolus Robertson. Since two of the aberrant specimens were mistaken for and erroneously described as new taxa, the present paper draws attention to this phenomenon within bees and its potential to cause taxonomic confusion.


Plant Extract Efficacy On Mosquito Mortality: Preliminary Studies On The Effect Of Ailanthus Altissima Extract On Adult Aedes Aegypti And Culex Quinquefasciatus, John R. Wallace, Calen D. Wylie, Ryan L. Wagner Nov 2021

Plant Extract Efficacy On Mosquito Mortality: Preliminary Studies On The Effect Of Ailanthus Altissima Extract On Adult Aedes Aegypti And Culex Quinquefasciatus, John R. Wallace, Calen D. Wylie, Ryan L. Wagner

The Great Lakes Entomologist

Abstract

Due to the negative environmental impact and resistance to synthetic insecticides, the development of biological control has increased significantly over the past half century with the potential of plant extracts only recently attracting attention. The purpose of this preliminary study was to examine the potential of Ailanthus altissima extract as a botanical insecticide on adult mosquitoes. Two species of mosquitoes (Aedes aegypti and Culex quinquefasciatus) and a non-target lepidopteran species, Painted Lady butterfly (Vanessa cardui) were treated with A. altissima extract from new, mature, and senesced leaflets using serial dilutions (0, 25, 50, 75, 100%) …


Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer Nov 2021

Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer

The Great Lakes Entomologist

Naturally occurring predator and parasitoid communities are well known to respond to multiple scales of environmental heterogeneity within and around agroecoystems, yet our understanding of which scales are most influential on different functional guilds of enemies is limited. Using vote-counting methodology, we synthesized the results from 40 empirical studies that observed how natural enemy richness, diversity, or parasitism rate is affected by environmental heterogeneity at a local scale (e.g. a focal field), an intermediate scale (e.g. habitat in immediate proximity of a focal field), and landscape scale (e.g. habitat within >200 m radius around focal field). Heterogeneity at all scales …


Spiraling Flight Behavior May Integrate The Biological Compass Systems Of Migratory North American Monarch Butterflies, (Danaus Plexippus, L.), Matthew M. Douglas Nov 2021

Spiraling Flight Behavior May Integrate The Biological Compass Systems Of Migratory North American Monarch Butterflies, (Danaus Plexippus, L.), Matthew M. Douglas

The Great Lakes Entomologist

Here I report a unique spiraling flight and orientation behavior (comprising multiple clockwise and counterclockwise circles coupled by extended figure-8 patterns) observed in free-flying “late” migratory monarchs released under sunny ambient field conditions from a location with an unobstructed view of the sky. Following this spiraling flight, migrants continue to fly at very high altitudes until a final orientation and migratory flight direction is established with vanishing bearings statistically concentrated to the SW/W. These results provide preliminary evidence for the possible calibration and use of an inclination magnetic compass that can be used under all local free-flying field conditions. During …


Susceptibility, Preference, And Suitability Of Carpinus And Ostrya Taxa For Gypsy Moth Larvae (Lepidoptera: Lymantriidae), Fredric Miller, Susan Wiegrefe Nov 2021

Susceptibility, Preference, And Suitability Of Carpinus And Ostrya Taxa For Gypsy Moth Larvae (Lepidoptera: Lymantriidae), Fredric Miller, Susan Wiegrefe

The Great Lakes Entomologist

Twenty Carpinus taxa and three Ostrya taxa, growing in the tree breeding production area at The Morton Arboretum, Lisle, IL, were evaluated in laboratory bioassays for feeding susceptibility, preference, and suitability for gypsy moth (Lymantria dispar, L.) larvae. No-choice and multiple-choice laboratory feeding studies revealed that C. coreana, C. fargesii, C. laxiflora, and the hybrid C. caroliniana x C. orientalis were the least suitable for larval development and pupation, and were less preferred by gypsy moth larvae. Suitability rankings for gypsy moth larval development time were highly correlated with larval longevity, but the proportion of …


Influence Of Age On Decision Making By Ovipositing Pieris Rapae (Lepidoptera: Pieridae)., Brett Breitkreutz, Tracy Le Wagner, Rodrigo J. Mercader Nov 2021

Influence Of Age On Decision Making By Ovipositing Pieris Rapae (Lepidoptera: Pieridae)., Brett Breitkreutz, Tracy Le Wagner, Rodrigo J. Mercader

The Great Lakes Entomologist

Due to its effect on the time available for host selection and learning, butterfly age is expected to alter the degree of host specificity and potentially niche breadth. Here, we use the small cabbage white, Pieris rapae L., to test the effect of age on ovipositional specificity and decision-making time. Specifically, we examined the ovipositional behavior of P. rapae 4, 8, and 12 days post-emergence. Females were recorded in thirty-minute trials using leaves of two hosts, mustard leaves, Brassica juncea, and collard greens, Brassica oleracea Acephala group, and the non-host common bean, Phaseolus vulgaris. Subsequently, we measured …

Conclusion: Female Leaders Using Coercive Power Motivate Subordinates, Mary Kovach Jul 2021

Conclusion: Female Leaders Using Coercive Power Motivate Subordinates, Mary Kovach

The Journal of Values-Based Leadership

This manuscript advances prior research (Blau, 1964; Elangovan & Xie, 1999; French & Raven, 1959; Goodstadt & Hjelle, 1973; Hegtvedt, 1988; Randolph & Kemery, 2011; Zigarmi, Peyton Roberts, & Randolph, 2015) and capitalizes on supervisory skills using power dynamics within the workplace, by investigating employee effort resulting from gender dissimilar supervisor-employee dyads and employee locus of control. To offer a more focused approach, this is an evaluation specifically on reward and coercive power derived from French and Raven’s (1959) five power bases. This manuscript proposes that the motivation levels of employees change, based on their locus of control and gender. …


Modern Approaches For Antiandrogen-Resistant Prostate Cancer Therapy, Felix Voinea, Laura Mazilu, Ioan Sergiu Micu, Adrian Paul Suceveanu, Madalina Iliescu, Andrada Dumitru, Vlad Denis Constantin, Ioana Paunica, Andra Iulia Suceveanu Apr 2021

Modern Approaches For Antiandrogen-Resistant Prostate Cancer Therapy, Felix Voinea, Laura Mazilu, Ioan Sergiu Micu, Adrian Paul Suceveanu, Madalina Iliescu, Andrada Dumitru, Vlad Denis Constantin, Ioana Paunica, Andra Iulia Suceveanu

Journal of Mind and Medical Sciences

Prostate cancer represents the leading malignant tumor in men over 50 years of age with 400,000 new cases being diagnosed yearly in Europe. Even if the incidence rate is higher than the mortality rate, still there is an increasing trend when speaking of its mortality. The increasing incidence of the metabolic syndrome, the unhealthy lifestyle, the high lipid and Calcium intake, the high spread of infections with Human Papilloma Virus, Human Herpes Virus, the excess of androgen consumption and the longer life expectancy, are few of the main causes of prostate cancer increasing incidence. The new systemic therapies such as …


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 Feb 2021

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 Feb 2021

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., Matthew Desko, Carolyne Schiebel, Samantha Silverman, Jessica Bickel, Karen Felton, Jennifer L. Chandler Feb 2021

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, Elson J. Shields, Antonio M. Testa Feb 2021

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 …

Satyshur, Thea A. Evans, Britt M. Forsberg, Robert B. Blair Feb 2021

Minnesota State Records For Osmia Georgica, Megachile Inimica, And Megachile Frugalis (Hymenoptera, Megachilidae), Including A New Nest Description For Megachile Frugalis Compared With Other Species In The Subgenus Sayapis, Colleen D. Satyshur, Thea A. Evans, Britt M. Forsberg, Robert B. Blair

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 …
