Oviposition-Deterrent And Repellent Effects Of Synthetic Plant-Derived Compounds On The Pulse Beetle, Callosobruchus Chinensis (Coleoptera: Chrysomelidae: Bruchinae), Akki Suma, M Rajadurai, Ac Lokesh, Mb Anusha, S Krishna Kumar

The Philippine Agricultural Scientist

The pulse beetle, Callosobruchus chinensis (Linnaeus, 1758), is a major stored pest of pulses (Fabaceae) in India. While effective control of this widespread and destructive insect pest is essential, continuous insecticide use poses environmental concerns, thereby necessitating alternative, eco-friendly control methods. This study evaluated the oviposition-deterrent effects of 7 synthetic compounds (linalool, guaiene, citral, estragole, 4-nonanone, alloaromadendrene, and citronellal) on C. chinensis. Linalool showed the strongest suppression of egg-laying at higher concentrations, with the lowest egg count at 500 ppm compared to the control, followed by citral, citronellal, and guaiene. Linalool was also effective in suppressing egg hatching at …

Elucidating The Functions Of Gut Microbiota From Two Edible Dung Beetle Species: Implications For Waste Management And Food Industry, Syombua S. Mwanza, Cynthia M. Mudalungu, John Mark Makwatta, James Kabii, Njogu M. Kimani, Chrysantus M. Tanga

All Peer-Reviewed Publications

Dung beetle larvae are consumed globally, yet their gut microbiota across different geographical locations remains largely unexplored. This study examined the diversity and composition of the gut microbiota of two edible dung beetle species, Cetonia aurata and Rhinoceros beetle (Oryctes sp.), from three sites in Kenya. Using advanced molecular techniques, bacterial and fungal communities were sequenced. The most abundant bacterial phyla in C. aurata were Firmicutes (42.10%) and Bacteroidota (32.50%), while Oryctes sp. had higher levels of Proteobacteria (35.00%), Actinobacteriota (11.40%) and Desulfobacterota (7.40%). Fungal communities were dominated by Lecanoromycetes (92.60%) in Oryctes sp. and Saccharomycetes (92.60%) in C. aurata. …

An Eco-Epidemiological Model For Malaria With Microsporidia Mb As Bio-Control Agent, Charlène N.T. Mfangnia, Henri E.Z. Tonnang, Berge Tsanou, Jeremy Keith Herren

All Peer-Reviewed Publications

Microsporidia MB is an endosymbiont which naturally infects Anopheles mosquitoes. Due to its ability to block Plasmodium transmission, it shows potential as a bio-based agent for the control of malaria. Its self-sustainability is promising, as it can spread through both vertical and horizontal transmissions. However, its low prevalence in mosquito populations remains a challenge. We develop an eco-epidemiological mathematical model describing the co-dynamics of Microsporidia MB (within mosquito population) and malaria (within human population). The model is used to assess the potential of Microsporidia MB-infected mosquitoes on the control of malaria infection. The results on the basic reproduction numbers, the …

Increasing interest in consuming insects is accelerating the expansion of the fortified snacks market. However, there is limited knowledge of the drivers of consumers to appreciate the role of desert locust [DL] Schistocerca gregaria Forskål as emerging functional ingredient for use in the food industry. Here, we evaluated the nutrient profile and functional properties of wheat breads fortified with powder from captive mass reared DL. The crude protein values of processed DL meal fed on three different food plants ranged between 40 and 56 %. The specific volume and firmness of the breads correlated positively and negatively, respectively, with incremental …

Modelling The Environmental And Terrestrial Drivers Of The Spread Of The Invasive Fall Armyworm Spodoptera Frugiperda In Africa, Marian Adan, Henri E.Z. Tonnang, Klaus Greve, Christian Borgemeister, Georg Goergen

All Peer-Reviewed Publications

The Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lep.: Noctuidae) a destructive invasive pest, poses a significant threat to maize cultivation in Africa, highlighting the need for a better understanding the factors affecting its prevalence. In this study we utilized the Maxent modelling approach to assess the impact of environmental and terrestrial parameters on the spread of FAW in Africa. We compared four different models based on their predictive accuracy: the most comprehensive model, which included bioclimatic factors, landscape structure, and FAW phenology, achieved an accuracy of 0.902. In contrast, models using only single categories of variables yielded lower accuracies, …

One Health Interventions And Challenges Under Rural African Smallholder Farmer Settings: A Scoping Review, Evanson R. Omuse, Honest Machekano, Bonoukpoè M. Sokame, Daniel M. Mutyambai, Thomas Dubois, Sevgan Subramanian, Frank Chidawanyika

All Peer-Reviewed Publications

The global human population is rapidly increasing, escalating interactions of people, animals and the environment. This has led to more convoluted health challenges, for which African smallholder farmers bear the brunt. The One Health (OH) approach recognises the interconnectedness of these health challenges and thus follows a transdisciplinary approach involving diverse stakeholders to address them. Although there have recently been global concerted efforts and studies on OH, an information gap exists in Africa, particularly regarding smallholder farmers and their needs. Additionally, evaluation frameworks and outcome metrics for OH initiatives are still unclear. Thus, this study was conducted to critically map …

Microbial Composition And Bioremediation In Frass Fertilizers From Insect-Based Agri-Food Waste Valorization, María Gómez-Brandón, Dennis Beesigamukama, Maraike Probst, Thomas Klammsteiner, Jian Qiang Su, Yong Guan Zhu, Chrysantus Mbi Tanga

All Peer-Reviewed Publications

Insect frass fertilizer is emerging as a sustainable and novel input for improving soil health and crop production; however, research attention on its safety and microbial properties remains limited. Here, we evaluated the levels of heavy metals, pathogens, diversity, abundance, composition and functional roles of bacteria and fungi in frass fertilizer produced by eight edible insect species. Our results revealed the absence of Salmonella spp. In the frass fertilizers produced by all insect species, while the levels of other pathogens and heavy metals were within permissible limits for organic fertilizers. We found that 79–86 % of the variations in bacterial …

Diversity And Activity Of Ground-Dwelling Spiders (Araneae) In Four Sub-Communities In A Degraded Oak Woodland At The Chicago Botanic Garden, Cook County, Illinois, James F. Steffen, Michael L. Draney

The Great Lakes Entomologist

Ground-dwelling spiders were sampled using pitfall traps over a twelve-month period from four sub-communities within a 40-ha oak woodland complex in northern Cook County, Illinois. Mesic and dry mesic oak woodland, mesic upland forest, buckthorn dominated mesic oak savanna and a mesic woodland control, where no restoration management is planned, were sampled. Fifty-five species within 44 genera and 18 families were trapped. The results suggest negative correlations between non-native spider abundance and spider species richness. Also, phenology of the various species indicates that a year-round inventory is necessary to adequately sample ground-dwelling spider assemblages. Possibilities of using Bathyphantes concolor (Wider) …

Biology And Larval Morphology Of Agrilus Subcinctus (Coleoptera: Buprestidae), With Comparisons To The Emerald Ash Borer, Agrilus Planipennis, Toby R. Petrice, Robert A. Haack, John S. Strazanac, Jonathan P. Lelito

The Great Lakes Entomologist

Emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an exotic invasive pest of ash (Fraxinus spp.) trees that was first discovered in North America in 2002. There has been concern that surveyors could confuse immature stages of EAB with A. subcinctus Gory, an ash borer native to North America. We conducted studies in 2006-2009 in southern Michigan to determine biological and morphological characters for distinguishing immature A. subcinctus and EAB life stages. Agrilus subcinctus adults were captured on yellow sticky cards from late May through mid-August, with peak flight occurring in June. Agrilus subcinctus egg laying began in …

Odonata Of Coastal Peatland Habitats Adjacent To Lake Superior In Wisconsin, Robert B. Dubois, Julie M. Pleski, William A. Smith, Eric J. Epstein

The Great Lakes Entomologist

We sampled adults and exuviae of Odonata in eleven coastal fens and poor fens near Lake Superior in Douglas, Bayfield, and Ashland counties in Wisconsin to determine species that were breeding in these areas, and gain knowledge about their relative abundances, flight periods, and nymphal habitats. The flora in these fens was characterized by mats of Sphagnum mosses, a variety of ericaceous shrubs, and a number of sedges, among which Carex lasiocarpa Ehrhart (slender sedge) was most dominant. We averaged seven visits per site from early June through September, 2004, to cover the flight periods of most species of Odonata …

Habitat Distribution Of Carabid Beetles (Coleoptera: Carabidae) In Northern Hardwood Forests Of Michigan, Holly A. Petrillo, John A. Witter

The Great Lakes Entomologist

We compared carabid beetle communities in northern hardwood forests and divided these forests into three categories based on overstory composition and geographic location: Northern red oak-American beech (Quercus rubra L.-Fagus grandifolia Ehrh.) in the Lower Peninsula (OBLP), sugar maple- American beech (Acer saccharum Marsh.) in the Lower Peninsula (MBLP), and sugar maple- American beech in the Upper Peninsula (MBUP). Carabid beetles were collected using pitfall traps in 36 stands in 2003-2004. We found that carabid composition changed throughout the collection periods. Pterostichus pensylvanicus LeConte and Sphaeroderus lecontei Dejean comprised 76% of the trap catches in May while Synuchus impunctatus (Say) …

Spatiotemporal Variation Of Violet-Feeding Large Fritillaries (Euptoieta, Speyeria) (Lepidoptera: Nymphalidae) In Central And Northern Wisconsin, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

We analyzed the relative abundance of the large fritillaries Euptoieta claudia (Cramer) (immigrant), Speyeria cybele (Fabricius) and S. atlantis (Edwards) (generalists), S. aphrodite (Fabricius) (grassland species), and S. idalia (Drury) (prairie specialist) in transect surveys at grasslands and pine barrens during 1990-2006 for variation and correlation over time (measured both as chronological year and as years since last management treatment) among six subregions in central and northern Wisconsin. Population trends (correlations of abundance with chronological year) were few and not significantly skewed toward either negative or positive trends. Spatial synchrony between pairs of subregions was significantly different among species, and …

The Native And Introduced Bark And Ambrosia Beetles Of Michigan (Coleoptera: Curculionidae, Scolytinae), Anthony I. Cognato, Nicolas Barc, Michael Philip, Robert Mech, Aaron D. Smith, Eric Galbraith, Andrew J. Storer, Lawrence R. Kirkendall

The Great Lakes Entomologist

Our knowledge of the biogeography of Scolytinae of eastern temperate North America is very patchy. We used data from hand collecting, trapped material (from 65 of 83 counties), and museum collections, supplemented by literature records, to compile a list comprising 107 bark beetle species in 45 genera for Michigan, a state with an especially rich diversity of woody plants. We provide detailed collection data documenting 32 species not previously catalogued for Michigan, 23 of which are new state records; the genera Trypophloeus and Trischidias are reported from Michigan for the first time. Fifteen Michigan scolytines are not native to North …

Fleas Of The Norway Rat In The Superior, Wisconsin, Harbor Area (Siphonaptera: Ceratophyllidae, Hystrichopsyllidae), Darol L. Kaufmann, Norman D. Radtke

The Great Lakes Entomologist

The occurrence of the fleas of the Norway rat, Rattus noruegicus (Berkenhout) was monitored in Superior, Wisconsin, for 12 months. A total of 441 fleas was recovered from 300 rat hosts. Nosopsyllus fasciatus (Bosc), the northern rat flea, was the most abundant species found (94.1%) while Ctenophthalmus pseudagyrtes pseudagyrtes Baker (5.4%) and Megabothris asio asio (Baker) (0.5%) were also present. The flea index was highest (4.8) in July and lowest (0.2) in February and March. Forty-four percent of the rats examined were infested.

Simulation Of The Effects Of Stand Factors On Spruce Budworm (Lepidoptera: Tortricidae), W. P. Kemp, J. P. Nyrop, G. A. Simmons

The Great Lakes Entomologist

A model was developed to simulate the life history of instar-I through instar-I1 spruce budworm, Choristoneura fumiferana (Clemens). Particular emphasis was given to the redistribution phases during spring and fall and the factors affecting budworm survival. Analyses included the effects of aggregated stand types, temperature, cloud cover, open areas, and the species distribution, on redistribution mortality. Of those stand factors examined, open area and non-host percentages were the most important in regulating redistribution survival.

Size Reduction Southward In Michigan's Mustard White Butterfly, Pieris Napi (Lepidoptera: Pieridae), W. H. Wagner Jr., Michael K. Hansen

The Great Lakes Entomologist

[Excerpt]

The mustard white, Pieris napi (Linnaeus) is generally considered to be a circumboreal species or species-complex. Much disagreement exists regarding the classification in this group, the members of which are extremely diverse, especially in Eurasia. There is evidently "a continuous range of differentiation, from local populations, through subspecies, to species, which nomenclature cannot fully reflect" (Bowden 1972). In North America the major controversy has been whether the so-called West Virginia white, P. virginiensis Edwards, should be separated as a distinct species. Most writers today agree that it should. Of the mustard white in the Great Lakes area, the local …

An Annotated List Of The Checkered Beetles (Coleoptera: Cleridae) Of Michigan, D.C. L. Gosling

The Great Lakes Entomologist

[Excerpt]

The checkered beetles (Cleridae) have been included in local lists of Michigan Coleoptera by Andrews ( 1916, 192 1, 1929), Hatch (1924), Hubbard and Schwarz (1878). LeConte (1850), and Wolcott (1909). The present list is the first to include records from throughout the state, and is based on the collections of the University of Michigan Museum of Zoology (UMMZ), those of the Department of Entomology, Michigan State University (MSUC), and the private collections of E. F. Giesbert, D. K. Young, and the author. This list records 35 species of Cleridae from the state, and I believe it is essentially …
