Visual Cues Attract Adult Tunga Penetrans (Siphonaptera: Tungidae), Ayako Hyuga, Paul Ouma, Lynne Elson, Kazuchiyo Miyamichi, Satoshi Kaneko, Kensuke Goto, Tullu Bukhari, Jürgen Krücken, Ulrike Fillinger

All Peer-Reviewed Publications

Tunga penetrans (Linnaeus, 1758) (Siphonaptera: Tungidae) is an ectoparasitic flea whose adult females cause tungiasis by embedding into the host’s skin. Environmental, social and financial challenges in tungiasis endemic areas have left this disease neglected and lacking locally available control measures. One possible approach for controlling T. penetrans targets its off-host stages; however, surveillance tools for adult fleas are still lacking. Moreover, host-seeking cues and behaviour of adult T. penetrans remain largely unknown. In this study, we show that visual cues are attractive to adult T. penetrans. Newly emerged T.penetrans responded to light stimuli across a broad spectrum, ranging from …

The Influence Of Ecological Pest Management Practices On Pests And Natural Enemies Under A Cabbage–Garden Pea Rotational System In Central Kenya, Peter Nyakundi Mageto, Milka Kiboi, Monicah Mucheru-Muna, Felix Matheri

All Peer-Reviewed Publications

Pest pressure is a major constraint on crop production in Sub-Saharan Africa, where smallholder farmers rely heavily on synthetic pesticides with potential environmental and health risks. Ecological pest management practices (EPMs) have been proposed as sustainable alternatives, although field-based evidence is limited. This study evaluated pest and natural-enemy responses to EPMs in a cabbage–garden pea rotation system over six years (2020–2025) in Central Kenya. Four treatments were assessed: homemade botanical extracts (Botanicals), coriander intercropping (Intercrop), botanical extracts combined with coriander intercropping (Botanicals + Intercrop), and a control. In cabbage, ecological treatments often recorded lower aphid and diamondback moth abundance and …

Exotic Two-Spined Trap-Jaw Ants (Odontomachus Haematodus) In Urban Parks Of Hattiesburg, Mississippi: Recommended Sampling Methods And Notes On Nesting Biology, Caroline M. Marley, Vinny Halsey, Lila Blackburn, Kayla D. Stan, Kaitlin M. Baudier

Midsouth Entomologist

The two-spined trap-jaw ant, Odontomachus haematodus (Linnaeus), is native to South America and was introduced to the United States via Mobile, Alabama in the mid-twentieth century. Misidentification as a native congener for several decades has inhibited the study of the ecology of O. haematodus in its introduced range within the Gulf Coastal Plain. We conducted a multimethod survey to: 1) assess the abundance of O. haematodus across urban parks in Hattiesburg, MS, the northernmost published record in this species’ exotic range, 2) establish which sampling methodologies are most effective for conducting urban surveys of O. haematodus, and 3) study …

Catalogue Of The Water Striders (Hemiptera: Gerridae) Of Mississippi, Chase G. Fry, Patricia L.S. Wooden

Midsouth Entomologist

Water striders (Hemiptera: Gerridae) are skating aquatic insects with piercing-sucking mouthparts that opportunistically feed on prey trapped by surface tension. The presence or absence of water striders and other aquatic Hemiptera in water systems may be important indicators of water quality. Despite their importance, the last aquatic Hemiptera checklist for the state was published in 1988. Since this publication, humans have altered waterways to meet their needs, and Gerridae taxonomy has continued to evolve. This study aims to create a current checklist of Gerridae, to provide a more comprehensive understanding of the species found in Mississippi before aquatic habitats are …

Estimated management costs and losses due to insects and other invertebrates in soybeans during the 2025 growing season were collected and compiled from 20 states to provide a record of insect pressure and management practices for the year. These annual estimates provide a historical record of pest pressure and insect management and have been compiled in some states since 2004. Participating states accounted for 68% of soybean acreage in the United States, with near 100% participation in the southern states. As has been true in previous years, the stink bug complex was the costliest insect pest in soybean followed by …

Assessing Integrated Pest Management Protocols For The Invasive Aquatic Weed Giant Salvinia (Salvinia Molesta), Samantha Lee Prinsloo

LSU Doctoral Dissertations

Giant salvinia (Salvinia molesta) is free-floating aquatic fern that originates from South America. Through human introduction, giant salvinia has escaped its native range and is listed as an invasive species across multiple continents causing negative socio-economic and environmental impacts. This research aimed to expand our understanding of integrated pest management for controlling giant salvinia by combining chemical and biological control. The objectives were to assess the effects of rainfastness, carrier volume, and growth stage on herbicide efficacy, assess augmented biological control and optimal weevil release densities, assess weevil populations in the field, determine herbicide and surfactant toxicity to …

Utilizing Diapause In A Sugarcane Borer (Lepidoptera: Crambidae) Laboratory Colony As A Cost Saving Measure, W. H. White

Midsouth Entomologist

The ability to rear insects in the laboratory broadens the scope of research opportunities available to the scientist. Our laboratory routinely rears the sugarcane borer, Diatraea saccharalis (F.), for research in host plant resistance and biological control of this important sugarcane pest. Unfortunately, insect rearing is a costly process. One option to reduce cost is to hold a founder population in diapause during times when insects are not needed. These insects can then be brought out of diapause and allowed to reconstitute the colony. A procedure was developed to put larvae of the sugarcane borer into diapuase, hold these larvae …

Mechanistic And Spatio-Temporal Modelling Of Cassava Whitefly (Bemisia Tabaci) Risk Under Climate Change: Projections For Africa With Case Evidence From Malawi, Lumbani Benedicto Banda, Frank Thomas Ndjomatchoua, Ritter A. Guimapi, Komi Mensah Agboka, Abdelmutalab G.A. Azrag, Wezi G. Mhango, Trust Kasambala Donga, Chikondi Makwiza, Karl H. Thunes, Elfatih M. Abdel-Rahman

All Peer-Reviewed Publications

The cassava whitefly (Bemisia tabaci) greatly constrains cassava production across Africa due to its role as a vector of viral diseases that cause substantial yield losses. Effective management of this insect pest requires detailed knowledge of its spatio-temporal distribution, however long-term datasets are scarce. Mechanistic models circumvent these long-term data needs by modelling temperature-dependent processes that govern population dynamics. Nevertheless, their application to B. tabaci remains poorly explored. Here, we developed a mechanistic model to derive a risk index (RI) for B. tabaci across Africa, focusing on Malawi. The model integrates the effects of temperature on the life stages of …

Every year, over 700,000 people, particularly children under five, die from vector-borne diseases worldwide. Effectively controlling endemics and preventing new outbreaks requires an integrated approach that can lead to the elimination of both vectors and diseases. In the last two decades, integrating medical interventions and vector control has significantly reduced the incidence of Gambian Human African Trypanosomiasis (g-HAT), with the World Health Organization validating eight countries as having eliminated the disease as a public health problem. However, elimination of the tsetse vector has not been confirmed, leaving the possibility of re-emergence. We developed a six-step modeling framework to assess vector …

Immune Suppression And Metabolic Reprogramming In Bactrocera Dorsalis Parasitized By Fopius Arisanus, Rehemah Gwokyalya, Jeremy Herren, Thomas Ogao Onchuru, Sahadatou Mama Sambo, Cassandra Purity Ronnie, Ndlela Shepard, Sunday Ekesi, Samira A. Mohamed

All Peer-Reviewed Publications

Abstract – Bactrocera dorsalis is a major horticultural pest. Biocontrol using parasitoids, such as Fopius arisanus, is a sustainable tool for managing this pest. However, the mechanisms enabling the successful parasitism of B. dorsalis are poorly understood. Using transcriptomic profiling, cellular bioassays, and targeted metabolite analyses, we investigated how F. arisanus modulates the immunity and metabolic activity of B. dorsalis to achieve a high parasitism rate. Our results revealed a weak and late encapsulation response of B. dorsalis towards F. arisanus. Additionally, parasitism reduced the number of circulating haemocytes by 35%, lowered constitutive granulocyte counts and inhibited phenoloxidase activity in …

Life-Stage Specific Predatory Efficiency Of 2 Generalist Predators Of Bemisia Tabaci (Hemiptera: Aleyrodidae), Itohan Aigbedion-Atalor, Abdelmutalab G. Azrag, Alvin M. Simmons, Jason M. Schmidt

All Peer-Reviewed Publications

Bemisia tabaci (Gennadius) is an economically damaging invasive pest to global vegetable production. Current management strategies rely heavily on insecticides, but increasing levels of resistance raise sustainability concerns. Therefore, strengthening integrated pest management (IPM) programs requires enhancing biocontrol through improved predator-pest interactions. Despite the well-established relevance of functional response modulation by multiple environmental factors, limited research has explored how plant traits and prey life stages interact to influence the efficiency of generalist predators in vegetable systems. To address this gap, we evaluated the functional responses of 2 adult generalist predators, Hippodamia convergens (Guérin-Méneville) and Geocoris punctipes (Say), against 3 nymphal …

Can Generative Ai Make Farming Decisions? Current Status And Future Pathways: A Case Study In Row Crop Production With Chatgpt, Nipuna Chamara, Yufeng Ge, Joe Luck, Yu Pan, Saleh Taghvaeian, Cory Walters, Christopher Proctor, Daran Rudnick, Daren Redfearn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The agricultural decision-making process is experience-based, knowledge-dependent, time-sensitive, complex, and driven by historical data. Planting, fertilization, irrigation, and chemigation are key categories in farm decision-making, and currently there is no one-shot decision-support tool that covers all these activities. Generative Artificial Intelligence (AI) models are more advanced than traditional machine learning and deep learning models. These models have been trained on vast amounts of data from the internet, allowing them to accept unstructured data in various forms and generate human-like text, solutions to problems, and scenario predictions. Given this capability, we became interested in exploring the potential of generative AI in …

Sunflower (Helianthus annuus) productivity is highly dependent on pollinators, yet the effects of climate on pollination services and crop yield remain poorly understood. In this study, we investigate how temperature gradients influence flower-visiting communities, pollination services, and sunflower productivity across Europe and Northern Africa. We conducted standardized two-year (2022 and 2023) pollination exclusion experiments across 36 sunflower fields spanning a broad climatic gradient, from temperate regions in Slovenia to arid conditions in Algeria. We found that sunflower production (seed set, seed number, and oil content) relied heavily on insect pollination. However, this benefit declined with rising temperatures, likely due to …

Climate-Driven Stochastic Modelling Of Crimean-Congo Haemorrhagic Fever Transmission In Uganda, P. G. Kpatchana, J. Aduda, K. M. Agboka

All Peer-Reviewed Publications

Crimean-Congo haemorrhagic fever (CCHF) is a climate-sensitive tick-borne zoonosis that remains a significant public health concern in Uganda, where temperature and vapour pressure deficit influence tick ecology and consequently disease transmission. This study aimed to develop and analyse a climate-driven stochastic model for CCHF transmission among ticks, livestock, and humans under environmental variability in Uganda. A compartmental transmission model was formulated and extended into a stochastic differential equation framework by incorporating multiplicative environmental noise. Climate-dependent tick recruitment, development, and mortality were parameterized using district-level temperature and vapour pressure deficit data to capture spatial heterogeneity in transmission risk. Theoretical analyses based …

Insects And Arthropods And Their Role In Human Society, Emily Marie Perez-Medina

Whittier Scholars Program

With brightly colored exoskeletons, an excess of both eyes and legs, and seemingly  unpredictable behaviors, insects and arthropods come across as unusual and strange to general audiences. For this reason, they are often classified as “gross,” “ugly,” or “scary,” antagonists  in popular culture. What is not recognized when being represented to the masses is how much human society depends on their presence, and how a world without insects would be a world without most things humans know and love. In order to help reduce the stigma of these tiny, yet mighty creatures, this project serves as a call to action …
