Aedes aegypti (Ae. aegypti) is the primary vector of several arboviruses, including dengue virus (DENV), chikungunya virus (CHIKV), yellow fever virus (YFV), and Zika virus (ZIKV). This vector is widespread globally in tropical and subtropical areas but also found in temperate areas. Kenya experienced its first chikungunya outbreak in Lamu County in 2004, followed by subsequent outbreaks in Mandera in 2016 and Mombasa in 2017. Despite the presence of Ae. aegypti in Kisumu and Busia counties, no outbreaks of chikungunya fever have been reported in these two western Kenya counties. To investigate this phenomenon, we collected Ae. aegypti mosquitoes from …

Widespread use of genetically engineered maize targeting the corn rootworm complex (Diabrotica species) has raised concerns about insect resistance. Twelve years of university field trial and farm survey data from ten United States Corn Belt states indicate that maize hybrids expressing toxins derived from the bacterium Bacillus thuringiensis (Bt maize) exhibited declining protection from rootworm feeding with increased planting while pest pressures simultaneously decreased. The analysis revealed a tendency to overplant Bt maize, leading to substantial economic losses; this was particularly striking in eastern Corn Belt states. Our findings highlight the need to go beyond the “tragedy of the …

Heller, Sarah Jandricic, M D. Marks, Yesuf Mohammed, William L. Perry, Winthrop B. Phippen, Lucas M. Roberts, Samantha Wells, Tad L. Wesley, Julia Zhang

The Great Lakes Entomologist

Pennycress is being developed in the Midwestern USA as a new oilseed crop that provides numerous ecosystem services. These services include being an early spring source of pollen and nectar for flower-visiting insects. Most past research on pennycress flower visitors used wild genotypes of pennycress. All wild genotypes have seed coats that are black, which occurs because of high levels of proanthocyanadins (PACs). Concentrations of PACs are minimal in newly developed genotypes with yellow-colored seed coats. However, little is known regarding flower abundance and timing nor insect visitation preferences for black-seeded genotypes (BSG) or yellow-seeded genotypes (YSG) of pennycress. Flower …

The Effect Of Temperature And Vegetative Substrate On The Short-Distance Dispersal Behavior Of An Invasive Weevil (Coleoptera: Curculionidae) To A Protected Dune Thistle, Alyssa S. Hakes, Tina Czaplinska, Monica Paniagua-Montoya

The Great Lakes Entomologist

The invasion of a seed-eating weevil, Larinus carlinae (Olivier, 1807) poses a threat to the persistence of native Pitcher's thistle (Cirsium pitcheri), a federally-threatened plant in sand dune communities of the western Great Lakes. At Whitefish Dunes (Sturgeon Bay, WI. USA), seed predation by weevils is higher for thistles surrounded by native marram grass (Ammophila breviligulata) than for those located in sandy habitats. In this study, we observed how the local abiotic and biotic environment affects the short-distance dispersal behavior of L. carlinae. Weevils were captured on site and individually released on the sand approximately …

Host Plant Resistance Of Viburnum Taxa For The Viburnum Leaf Beetle (Coleoptera: Chrysomelidae), Fredric Miller, Chad Rigsby Feb 2025

Host Plant Resistance Of Viburnum Taxa For The Viburnum Leaf Beetle (Coleoptera: Chrysomelidae), Fredric Miller, Chad Rigsby

The Great Lakes Entomologist

Thirty-five native and exotic Viburnum taxa were evaluated in a series of no-choice (NC) and multiple-choice (MC) laboratory feeding bioassays, and field defoliation studies for their relative susceptibility, palatability, and preference for viburnum leaf beetle (VLB) (Pyrrhalta viburni Paykull) larvae and adults. Overall, larval field defoliation was consistent with adult field defoliation, and adult VLB field defoliation mirrored the results from the NC laboratory feeding studies. Collectively, there was no significant difference in field defoliation between Asian and North American Viburnum taxa but leaf thickness was a good predictor for both the percent leaf tissue removed in NC laboratory …

Occurrence Of Spotted Wing Drosophila (Drosophila Suzukii) In Wild Berries In Forested Areas Of Marquette And Keweenaw Counties, Upper Peninsula Of Michigan, Alexis M. Shatrau, Erika I. Hersch-Green

The Great Lakes Entomologist

Spotted-wing Drosophila (SWD, Drosophila suzukii Matsumura, Diptera: Drosophilidae) is an invasive fly that targets unripe soft-fruits causing premature ripening, dehiscence, and rotting. While the presence of SWD in agricultural systems is well-documented, much less is known about the host range of SWD in wild areas, especially in more northern latitudes where colder temperatures and short summers are thought to restrict their life-cycles and limit population growth. In 2019 and 2020, we collected wild berries from two counties in the Upper Peninsula of Michigan, with long, cold winters, to determine the prevalence, host range, and seasonal/temporal variation of SWD. We found …

The Great Lakes Entomologist

During the 1990s, the United States Forest Service implemented several studies to measure the impacts of organic matter removal and soil compaction on forest productivity in forest ecosystems throughout the country. One site was in northeastern Lower Michigan on the Huron-Manistee National Forest in Oscoda County. This site was dominated by mature quaking aspen (Populus tremuloides Michx.) and bigtooth aspen (P. grandidentata Michx.) growing on sandy loam soils. The three organic-matter removal treatments at the site included: 1. stem-only harvesting (SOH); 2. whole-tree harvesting (WTH); and 3. whole-tree harvesting plus forest floor removal (FFR). The three soil compaction …

Long-Term Agricultural Management Reduces Abundance And Alters Community Structure Of Ground Beetles (Coleoptera: Carabidae), Cynthia M. Fiser, Nathan L. Haan, Douglas A. Landis

Entomology Faculty Publications

Carabid beetles (Coleoptera: Carabidae) are beneficial predators and bioindicators of ground-dwelling arthropod diversity in agricultural landscapes. We studied changes in community composition, activity density, and diversity of carabids in a long-term agroecosystem study spanning 30 years in the US Midwest. We contrasted carabid community metrics measured by pitfall trap sampling in two conservation-oriented treatments in a corn-soybean-wheat rotation. One treatment uses conventional practices but with reduced agrochemical inputs (Reduced Input), while the other has no synthetic inputs (Biologically Based). Since a 1994–95 study on the same site, in 2019 overall carabid activity density had declined a minimum of 58–76 % …

Effective identification and control of malaria vector larval breeding habitats are crucial for the management and eradication of malaria. Despite its importance, the last decade has seen a decline in data availability and intervention efforts due to reduced attention and prioritization. This study addresses the geographic data scarcity concerning Anopheles funestus larval breeding habitats in a malaria-prone region of western Kenya. Employing a two-step methodological approach, we integrated multi-criteria decision analysis (MCDA) and rule-based fuzzy logic analysis to evaluate the spatiotemporal similarity or divergence of these habitats. The analysis spanned a five-year interval, 2008, 2013, and 2018 with 2013 serving …

All Peer-Reviewed Publications

In recent decades, worldwide concerns about the health of honey bees motivated the development of surveys to monitor the colony losses, of which Sub-Saharan Africa has had limited representation. In the context of climate change, understanding how climate affects colony losses has become fundamental, yet literature on this subject is scarce. For the first time, we conducted a survey to estimate the livestock decrease of honey bee colonies in Kenya for the year 2021–2022 to explore the effects of environmental conditions, such as temperature and precipitation, on livestock decrease. We define “livestock decrease” from the beekeeper's perspective, including dead colonies …

Pulsating Drought And Insect Herbivory Cause Differential Effects On Soybean (Glycine Max) Genotypes That Vary In Canopy Wilting Speed, Jessica Ayala, Manish Gautam, Adrianna Peissel, George Justin, Rupesh Kariyat

Entomology and Plant Pathology Faculty Publications and Presentations

As a result of climate change, global temperatures are increasing, and water scarcity is on the rise. Soybean [Glycine max (L.) Merr] is one of the most important crops in the world due to its importance as food and feed. One of the major limiting factors for soybean production is drought, which can cause up to 80% reduction in yield. Therefore, growers and plant breeders are turning to soybean accessions that demonstrate better water use efficiency (WUE). However, in addition to drought, insect herbivory by soybean looper (Chrysodeixis includens, SBL) and fall armyworm (Spodoptera frugiperda, FAW) can also reduce soybean …

Spatiotemporal Variability And Functional Redundancy Obscure Effects Of Urbanization On Strawberry Pollinators, Kyla D. Schulte, Caleb J. Wilson, Anna Tawril, Mary A. Jamieson

Entomology Faculty Publications

Pollination services across rural–urban gradients may vary as land cover and other environmental attributes differentially influence pollinators. Most studies examining crop pollination, however, have been conducted in rural environments, while research in urban areas has lagged behind despite growing interest in urban agriculture. In this study, we hypothesized that increased urbanization would alter pollinator community composition due to a reduction in natural areas within the surrounding landscape, potentially decreasing pollinator abundance. To evaluate this hypothesis, we conducted a three-year study using strawberries as a focal study crop. We characterized the abundance, diversity, and community composition of bees across 10 farms …
