Agroecological approaches harnessing in-field biodiversity have been highlighted as a sustainable way to reduce yield gaps, but long-term assessments of their ability to buffer production from weather extremes and increasing interannual and intraseasonal climate variability are scarce. Here, we analyze a 12-year dataset from 642 control vs. push-pull maize field pairs in western Kenya, where long-term climate trends include increasing temperatures and intensifying drought and rainfall. In push-pull, maize is intercropped with a fodder legume that improves soil fertility, suppresses weeds, and deters pests, and is bordered with fodder grasses attracting and suppressing the pests. We assess interactions between push-pull …

Sexual Di(Et)Morphism: Using Experimental Evolution To Test Whether Resource Partitioning Promotes Divergence Of The Sexes In Drosophila Melanogaster, Owen A. Jamieson
Theses and Dissertations (Comprehensive)
Sexual dimorphism has been a long-studied phenomenon in the field of evolutionary biology. Usually, these differences in morphology, physiology and/or behaviour between the sexes are studied through the parsimonious lens of sexual selection. However, there are natural history cases where this lens does not seem applicable. Some species show sex specific morphological traits whose presence may not be due to a direct benefit to reproduction, but a difference in how each sex interacts with the environment and differing selective pressures from the environment on either sex. Darwin even brought up examples of this kind of dimorphism and pondered their existence, …

Mosquito-borne diseases such as malaria, dengue, chikungunya, Zika, and yellow fever pose a growing global health threat, worsened by resistance to synthetic pesticides. This study evaluated insect oils from Schistocerca gregaria, Ruspolia differens, and Macrotermes spp. as adjuvants in plant-based mosquito repellents. The formulations were tested for complete protection time (CPT) against Anopheles gambiae, Aedes aegypti, and Culex quinquefasciatus, and volatile organic compounds (VOCs) emitted from treated volunteers were analyzed. Incorporating insect oils doubled CPT compared to essential oils alone. The most effective blend of Macrotermes oil with Cymbopogon nardus (1:1) achieved CPTs of 3.50 h for An. gambiae, 2.56 …

The utilization of insect frass fertilizer in crop production systems has recently gained significant global interest, but there has been limited evidence of its residual benefits in rotational cropping systems. The legacy effects of black soldier frass fertilizers (BSFFF), conventional organic fertilizer (SAFI), inorganic fertilizer (NPK), synthetic nematicide, and their combinations on potato cyst nematode (PCN) management under potato-African nightshade rotational farming systems were investigated. Eight treatments were evaluated: BSFFF, SAFI, chitin-fortified BSFFF (BSFFF+5chitin), NPK + nematicide, combination of BSFFF and NPK so that each supplies 50% of the nitrogen required by potato (50BSFFF+50NPK), combination of SAFI and NPK so …

All Peer-Reviewed Publications
The invasion of fall armyworm (Spodoptera frugiperda; FAW) into Africa poses a major threat to agricultural systems, particularly maize production, necessitating effective biological control strategies. This study presents an ecological modelling framework that integrates temperature data with fractional differential equations (FDEs) to investigate interactions between FAW and its parasitoid natural enemies. By incorporating temperature-driven effects on life-history traits and ecological memory dynamics, the model captures key features of host–parasitoid interactions under variable environmental conditions. Equilibrium states corresponding to FAW extinction, parasitoid extinction, and coexistence were analytically derived, and sensitivity analysis of the FAW reproduction number highlighted its central role in …

Machine learning is transforming chemical ecology by accelerating the discovery and deployment of semiochemical-based tools for precision pest management. These advances are particularly important in the face of climate change, pesticide resistance, and the growing need for sustainable agricultural intensification. This review synthesizes how machine learning can be applied across the semiochemical discovery and implementation pipeline, from chemical signal detection to field deployment and decision support for integrated pest management. We review major machine learning approaches and demonstrate how they extract biologically relevant information from high-dimensional chemical, electrophysiological, behavioral, sensor, and field datasets. These methods accelerate semiochemical discovery, prioritize candidate …

The Great Lakes Entomologist
A reproductive population of Physocyclus enaulus Crosby, 1926 (Pholcidae: Araneae), a short-bodied cellar spider native to the American southwest and Mexico, is documented for the first time in a single building in Illinois, far outside of their known native range. The means of introduction is unknown but is likely influenced by either accidental hitchhiking spiders or a deliberate introduction to control brown recluse populations. Cellar spiders were purchased and released in the same building to predate on brown recluse spiders, but the first P. enaulus individual was found a year prior to the release. These cellar spiders have a wide-ranging …

Seasonal Emergence, Egg Gallery Characteristics, And Natural Enemies Of The Eastern Ash Bark Beetle, Hylesinus Aculeatus (Coleoptera: Curculionidae: Scolytinae), In Michigan, Robert A. Haack
The Great Lakes Entomologist
Hylesinus aculeatus Say (Coleoptera: Curculionidae: Scolytinae) commonly infests the trunks and limbs of recently dead, dying, or cut ash (Fraxinus spp.) trees in eastern North America. In the Great Lakes region, H. aculeatus is univoltine, overwinters as adults, breeds in late spring and early summer, and constructs transverse biramous egg galleries. I sampled trunk and branch sections from three small-diameter white ash (F. americana L.) trees that were cut in April 1986 in Ingham County, Michigan, and then naturally infested by H. aculeatus and associates. Bolts cut from these trees and placed in an outdoor rearing cage in …
Phenology Of Ground-Dwelling Beetle Assemblages (Coleoptera: Carabidae, Staphylinidae) From Three Fir Stands Of Southern Québec (Canada), With Comparison Among Selected Species Between 1985 And 2006-2010, Claire Levesque, Gilles-Yvon Levesque
The Great Lakes Entomologist
A total of 5,303 adult epigaeic beetles (Coleoptera) were collected using pitfall traps across three balsam fir (Abies balsamea (Linnaeus) Miller) stands in southern Québec (Canada). Sampling occurred during May–September 1985 in sites representing three distinct understory vegetation types. Three dominant families (Carabidae, Leiodidae and Staphylinidae) together represented at least 93% of catches at each site. Staphylinidae were less abundant than Carabidae at two sites, whereas Carabidae and Staphylinidae were collected in similar numbers at a third stand. Associated with increased abundance and heterogeneity of the understory vegetation, we observed 1) the decrease of specialist forest carabids, often active …

Paper Wasp Species Polistes Fuscatus (Hymenoptera: Vespidae) Tracks Urban Lead (Pb) Levels More Than Polistes Dominula, Lindsey R. Kemmerling, Anna L. Lovat, Allison A. Hanka, Emilie C. Snell-Rood
The Great Lakes Entomologist
Lead (Pb) is a persistent, toxic pollutant with widespread but inequitably distributed impacts, especially for humans in urban areas. The impacts of lead pollution on other organisms is largely unknown, even as they commonly experience exposure to lead alongside humans. We tested hypotheses regarding the lead concentrations of paper wasps across a gradient of pollution relative to soil and human lead levels, and correlations with wasp body condition. We collected two species of paper wasp across an urban gradient of lead pollution: Polistes fuscatus (Fabricius) (Hymenoptera: Vespidae), native to our study location, and Polistes dominula (Christ), nonnative to our study …

The Culver’s root borer moth (Papaipema sciata) (Lepidoptera: Noctuidae) is a rare Noctuid that requires Culver’s root (Veronicastrum virginicum) to complete its lifecycle within remnant native grasslands and open woodlands in the midwest and northeast United States. We report on 26 years of monitoring this species’ colonization of Culver’s root stems at Algonac State Park (ASP) in Michigan, where prairies have been maintained by prescribed fire since 1990. P. sciata is considered fire sensitive because eggs spend the dormant season in the combustible prairie litter and duff near host plants. The objectives were to determine the …

Could The European Thanasimus Formicarius Outcompete The North American Thanasimus Dubius (Coleoptera: Cleridae) If Introduced To North America?, Robert A. Haack, Robert K. Lawrence
The Great Lakes Entomologist
A federal quarantine was enacted in the United States (US) in the fall of 1992 in response to discovery of the Eurasian pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytinae), in July 1992 in Ohio. The quarantine regulated movement of pine products (e.g., Christmas trees, nursery stock, and logs) at the county level from infested to uninfested US states. A classical biological program was considered for T. piniperda starting in 1995, focusing on the Eurasian clerid beetle Thanasimus formicarius (L.), an important predator of T. piniperda. Concerns were raised in 1996 that if T. formicarius were released in the …

Fecundity Of Thanasimus Dubius (Coleoptera: Cleridae) Rebounds After A Period Of Prey Scarcity, Robert A. Haack, Robert K. Lawrence
The Great Lakes Entomologist
We field-collected Thanasimus dubius (Fabricius) (Coleoptera: Cleridae) adults during spring, maintained them separately in the laboratory, and initially gave them four bark beetle adults [Ips grandicollis (Eichhoff) or Tomicus piniperda (L.) (Coleoptera: Curculionidae: Scolytinae)] daily as prey. Using a subset of the female clerids (N = 41), we assigned them to one of four feeding groups that varied in the number of prey provided daily. For the first four weeks of a 12–week study, the four diets were: four prey daily, two prey daily, one prey daily, and one prey every 2 days. After four weeks, all females were …

The Great Lakes Entomologist
At least six described species of the herb gall wasp genus Antistrophus Walsh (Hymenoptera: Cynipoidea: Aulacideini) are dependent on the plant genus Silphium L., a plant group emblematic of now-endangered Midwestern tallgrass prairies. The distribution and conservation status of Antistrophus gall wasps is mostly a mystery, and these insects have only recently been recorded from Wisconsin. We surveyed the state for Antistrophus gall wasps on four Silphium species, whole-leaf rosinweed (S. integrifolium Michx.), compass plant (S. laciniatum L.), cup plant (S. perfoliatum L.), and prairie dock (S. terebinthinaceum Jacq.) to determine their distribution and abundance in Wisconsin.
