Collection Of Ground Beetles (Coleoptera: Carabidae) In Two Types Of Arboreal Terrain In The Natural Park Of Belezma Batna (North-Eastern Algeria), Yougherta Abderrezak Habbari, Naama Frah, Meriem Bouterfa, Larbi Houichi

Journal of Bioresource Management

The inventory of the carabid family at two forest sites in the Belezma national park namely an oak grove site and a cedar site during a period ranging from May 2017 to April 2018, has shown the counting of 27 taxa that have been inventoried by Barber pitfall traps. The results showed that the Quercus ilex site has slightly more species (25 species) compared to the Cedrus atlantica one (23 species). However, the Harpalinae subfamily is quantitatively the better one represented at both sites. The Shannon and Simpson indices report slightly higher figures in the Cedrus atlantica site with respectively …

A Push–Pull Strategy To Suppress Stable Fly (Diptera: Muscidae) Attacks On Pasture Cattle Via A Coconut Oil Fatty Acid Repellent Formulation And Traps With M-Cresol Lures, Alexander T. Lehmann, Gary J. Brewer, David J. Boxler, Junwei J. Zhu, Kathy Hanford, David Taylor, James A. Kenar, Steven C. Cermak, Jerome A. Hogsette

Department of Entomology: Faculty Publications

BACKGROUND: Stable flies [Stomoxys calcitrans (L.)] are economically important pests of cattle and other livestock. As an alternative to conventional insecticides, we tested a push–pull management strategy using a coconut oil fatty acid repellent formulation and an attractant-added stable fly trap.

RESULTS: In our field trials we found that weekly applications of a push–pull strategy can reduce stable fly populations on cattle as well as a standard insecticide (permethrin). We also found that the efficacy periods of the push–pull and permethrin treatments following on-animal application were equivalent. Traps with an attractant lure used as the pull component of the …

Taxonomic Placement And Nomenclatural Revisions For Five Species Of Neotropical Buprestidae (Coleoptera), Norman E. Woodley

Insecta Mundi

Autarcontes lopezi Fisher, 1925 (Coleoptera: Buprestidae), is transferred to the genus Agrilus Curtis, 1825 (new combination). Colobogaster bella Kirsch, 1873, is transferred to the genus Chrysobothris Eschscholtz, 1829 (new combination). Ectinogonia isamarae Moore, 1994, is resurrected as the valid name for the species previously called E. obscuripennis Cobos, 1954, as the latter is unavailable as infrasubspecific. Conognatha jakobsoni Obenberger, 1928, is resurrected over C. germaini Théry in Hoscheck, 1934, as the for­mer name has priority. Callimicra lucida Waterhouse, 1889, is resurrected as the valid name over C. hoscheki Obenberger, 1922, which has been used due to …

The Effects Of Prescribed Fire On Ant Community Composition In A Temperate Deciduous Forest, Emma Jones

2023 Midwest Ecology & Evolution Conference

Prescribed fire is a tool commonly used in land management to decrease wildfire frequency and promote plant diversity. However, the effects of prescribed fire on invertebrate communities, especially those within temperate deciduous forest, are poorly understood. We measured the response of epigeic ant communities in mixed mesophytic forest in Berea, Kentucky following prescribed burning. We used pitfall traps to repeatedly sample epigeic ants in replicate burned and unburned plots for up to 21 months postburn following two separate (2021 and 2022) prescribed fires. Ant species richness was similar between treatments (burn vs. control) and by burn year. Ant community composition …

Evolution Of A Genus Of Gall Wasp Kleptoparasites, Guerin E. Brown

2023 Midwest Ecology & Evolution Conference

Kleptoparasites do not directly parasitize their hosts but instead steal food and resources, reducing host fitness. Like direct parasites, kleptoparasites can be highly dependent on their hosts such that their evolutionary histories may be linked. Here, we study the evolution of a kleptoparasitic wasp genus, Synergus (Hymenoptera: Cynipidae: Synergini), in relation to their hosts, oak gall wasps (Hymenoptera: Cynipidae: Cynipini). Ovipositing oak gall wasps induce the formation of galls on oaks (Fagaceae) that provide food and shelter to one or more developing gall wasps. Galls induced by different gall wasp species are diverse in size, shape, color, and location …

Environmental Factors Shaping A Sawfly-Associated Community Of Parasitoids, Carson Kephart, Robin K. Bagely

2023 Midwest Ecology & Evolution Conference

A major goal of evolutionary biology is to understand the mechanisms that shape biodiversity, especially amongst highly speciose lineages such as parasitic wasps. However, most of these lineages are poorly described, with very little available natural history information. This lack of information limits our ability to uncover the environmental factors that contribute to their patterns of divergence, distribution, and abundance. To that end, here we take advantage of a community of hymenopteran parasites that has an unusually large amount of available information since they attack an economically important pine sawfly species, Neodiprion lecontei. We build upon a set of …

Efficacy Of Biocontrol Against Chrysomelid Pests In Lab Vs Field Studies: Potential Biases Of Setting And Phylogenetic Subgroups, Blake Hudson

2023 Midwest Ecology & Evolution Conference

The beetle family Chrysomelidae is a speciose group of voracious herbivores with a wide number of ecological implications. While some Chrysomelid species have been introduced or augmented as biological control agents of invasive plants, many other species have found success as economically important pests of field crops and stored grains, leading to severe yield losses in cucurbits, legumes, and other systems. Controlling such pests, especially in the field, is particularly difficult due to the timing of their complex life cycles, the fossorial nature of many species’ larvae, and ability to produce multiple generations in a single growing season. This study …

Association Of Excessive Precipitation And Agricultural Land Use With Honey Bee Colony Performance, Gabriela M. Quinlan, Rufus Isaacs, Clint R. V. Otto, Autumn H. Smart, Meghan O. Milbrath

Department of Entomology: Faculty Publications

Context From landscape variables to weather, multiple environmental factors affect honey bees and other pollinators. Detailed honey bee colony assessments in a variety of landscape and weather conditions offer the opportunity to develop a mechanistic understanding of how landscape composition, configuration, and weather are associated with colony nutrition, demography, and productivity.

Objectives Our objective was to test if weather and landscape characteristics (e.g., agricultural versus forested land use) are associated with different honey bee colony outcomes (foraged nectar mass, foraged pollen mass, pupal population size, and adult population size change).

Methods We collected detailed colony measurements on over 450 honey …

Myzus Fataunae Shinji (Hemiptera: Aphididae), Pilea Aphid, New To North America, Susan E. Halbert, Jade S. Allen, Matthew R. Moore, Katherine E.O. Fairbanks, Masakazu Sano, Gary L. Miller

Insecta Mundi

Minute aphids belonging to the species Myzus fataunae Shinji (Hemiptera: Aphididae) were found at a nursery in Seminole County, Florida. Morphological and molecular data support this determination. The Florida population only colonized species of Pilea Lindl. in our host range experiments. It did not colonize Fatoua villosa. Nakai. Likewise, it did not colonize tested common Florida species of Urticaceae other than Pilea spp. Myzus fataunae is adventive, and it appears to be established in the United States.

Biology Of Spodoptera Frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) On Rice And Different Corn Varieties, Anthony S. Agravante, Karen B. Alviar, Analiza Henedina M. Ramirez, Sheryl A. Yap

The Philippine Agricultural Scientist

Rice and corn are one of the most important crops in the Philippines. Several insect pests contribute to the losses and low yield of these crops. The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), was recently reported to cause economic damage to corn. Also, this insect consists of two genetically differentiated strains namely, the corn strain and the rice strain. This study was conducted in a laboratory conditions to evaluate the biological parameters of FAW on rice and corn varieties. Newly hatched larvae were fed such as the open pollinated variety (OPV), traditional variety, Macho F1 (hybrid), NK 6410 (genetically …

Susceptibility Of Pre-Adult Biological Stages Of Mythimna Separata (Walker) (Lepidoptera: Noctuidae) To Three Entomopathogenic Fungi (Hypocreales), Melissa P. Montecalvo, Marcela M. Navasero

The Philippine Agricultural Scientist

Armyworms are polyphagous insect pests of agricultural crops. Their population is usually managed below threshold level using insecticides. However, a single control measure is insufficient to attain a sustainable pest management. Hence, this research was conducted to assess the three species of entomopathogenic fungi as potential biological control agents against Mythimna separata (Walker) or paddy armyworm. Dose mortality assays were conducted to determine the pathogenicity of Beauveria bassiana (Bals.) Vuill., Metarhizium anisopliae (Metschn.) Sorokin, and Metarhizium rileyi (Farlow) Kepler, S.A. Rehner and Humber against various biological stages of M. separata including egg, 1^st to 6^th larval instars, prepupa, …

Investigating The Diversity Of Wolbachia Across The Spiny Ants (Polyrhachis), Jenna L. Webb, Leland C. Graber, Manuela O. Ramalho, Corrie S. Moreau

Biology Faculty Publications

Among insects, Wolbachia is an exceedingly common bacterial endosymbiont with a range of consequences of infection. Despite the frequency of Wolbachia infection, very little is known about this bacteria's diversity and role within hosts, especially within ant hosts. In this study, we analyze the occurrence and diversity of Wolbachia across the spiny ants (Polyrhachis), a large and geographically diverse genus. Polyrhachis samples from throughout the host genus' phylogenetic and biogeographical range were first screened for single infections of Wolbachia using the wsp gene and Sanger sequencing. The multilocus sequence typing (MLST) scheme was then used on these singly infected samples …

Preliminary Feeding Assessments For Asiatic Garden Beetle, Maladera Formosae (Coleoptera: Scarabaeidae), Grubs And Adults, Adrian J. Pekarcik, Matthew O. Lorentz, C. Scott Clem, Amy L. Raudenbush, David W. Held, Kelley J. Tilmon

The Great Lakes Entomologist

The Asiatic garden beetle, Maladera formosae (Brenske) (syn. M. castanea [Arrow]), is an annual white grub species that was unintentionally introduced from east Asia to North America in 1921 in New Jersey, and has since spread to at least 25 states and two Canadian provinces. Grub populations in the Great Lakes region have recently emerged as significant early-season pests of field crops, particularly field corn, grown in sandy soils. Asiatic garden beetle has also recently become established in other regions including Alabama. Prior research on this species was conducted mainly in the 1930s in horticultural and turfgrass systems of New …

The Great Lakes Entomologist

Abstract

A blacklight trap (LT) and a flight interception trap (FIT) were installed throughout the May-September period during four years (2014-2017), near a farm pond within an orchard at Compton, in southern Québec (Canada). We collected by LT 162,001 adults representing 560 beetle species and morphospecies belonging to 49 families, and using a FIT 10,159 individuals for 468 Coleoptera species belonging to 48 families. We observed a similarity of 9.8% between these two assemblages including 214 common species (26.3% of total of 814 caught taxa). We caught mainly nocturnal Carabidae, Hydrophilidae, Staphylinidae and Dryopidae in the LT, and primarily diurnal …

Seasonal Changes Of Benthic Macroinvertebrate Functional Feeding Group Biomass Within Forest And Meadow Habitats Of A First-Order Michigan (Usa) Stream, David C. Houghton, Erin Flaherty, Danae Sollie, Ryan Lardner

The Great Lakes Entomologist

Little is known about seasonal changes in stream benthic macroinvertebrate assemblages. We determined the ash-free dry mass of macroinvertebrates within a forested and a meadow reach of Fairbanks Creek in northern Lower Michigan throughout all seasons of 2018 and 2019. The macroinvertebrate assemblage of the forested reach was dominated by invertebrates in the shredder functional feeding group (FFG), whereas the meadow reach was composed primarily of scrapers and filtering collectors. Regardless of reach, the biomass of all FFGs was low during the winter and early spring, peaked in May or June, and gradually declined throughout the summer and fall. General …

Insect Floral Visitors Of Red Maple And Tree-Of-Heaven At Potential Risk Of Neonicotinoid Residue Exposure From Spotted Lanternfly Control, Jonathan Elmquist, Kelli Hoover, David Biddinger

The Great Lakes Entomologist

To manage spotted lanternfly (Lycorma delicatula (White)), an invasive planthopper recently introduced to the United States, governmental agencies, homeowners, and landscape professionals may treat its host plants with systemic neonicotinoid insecticides. Neonicotinoids can be harmful to non-target insect floral visitors collecting pollen or nectar. The insect floral visitors of red maple (Acer rubrum L.) or tree-of-heaven (Ailanthus altissima (Mill.), which are two of the preferred hosts of L. delicatula in Pennsylvania, are often targeted with neonicotinoid applications for control of this pest. To identify the floral visitors of these tree species, we conducted observations and collections of …
