Expansion Of The Knockdown Resistance Frequency Map For Human Head Lice (Phthiraptera: Pediculidae) In The United States Using Quantitative Sequencing, K J. Gellatly, S Krim, D J. Palenchar, K Shepherd, Kyong-Sup Yoon, C J. Rhodes, S H. Lee, J M. Clark

SIUE Faculty Research, Scholarship, and Creative Activity

Pediculosis is a prevalent parasitic infestation of humans, which is increasing due, in part, to the selection of lice resistant to either the pyrethrins or pyrethroid insecticides by the knockdown resistance (kdr) mechanism. To determine the extent and magnitude of the kdr-type mutations responsible for this resistance, lice were collected from 138 collection sites in 48 U.S. states from 22 July 2013 to 11 May 2015 and analyzed by quantitative sequencing. Previously published data were used for comparisons of the changes in the frequency of the kdr-type mutations over time. Mean percent resistance allele frequency (mean % RAF) values across …

Pollinator Garden, Paige E. Bradley

Engagement & Service-Learning Summit

The goal of the project is to increase awareness about global climate change and the necessity of environmentally sustainable practice, particularly among the younger citizens of the Lafayette area. The Lyn Greece Boys & Girls Club extended a hand and offered us land to install a pollinator garden on their campus and an opportunity to meet with the kids one-on-one to promote sustainability ideas and help them understand the basics of gardening. The project is as local as possible, using native plants, no pesticides or herbicides, Bennett's Greenhouse (a local business), and the resources on campus to reach out to …

Effect Of Coccidiodomycosis In Livestock, Robert Wood

Midsouth Entomologist

Coccidioidomycosis, also known as Valley Fever, is a fungal infection that affects most mammals. It is found throughout the semi-arid parts of the Americas. Valley Fever was first described in 1892 as a parasitic disease with high mortality and morbidity, but is now considered to be a low morbidity and mortality fungal disease. Although the disease could have long lasting effects that ultimately lead to death, likelihood of mortality is low. Additionally, morbidity is reduced with appropriate treatment.

Dengue Fever: Should We Be Concerned As Americans?, Shikinah D. Washington

Midsouth Entomologist

Dengue fever is a virus transmitted through mosquito bites. There are cases in many countries throughout the world that occur every few years. The disease does not kill many people, however, it can make the quality of life very poor and cause people to die who have underlying disease. There is no vaccine to prevent it, and it is a disease that we Americans should not take lightly. It is very possible for there to be an outbreak in the United States, therefore we need to all take precautions against it. An outbreak here or anywhere else in the world …

Investigating Physiological Collaborations Between A Lower Termite And Its Symbionts, Brittany F. Peterson

Open Access Dissertations

This project was completed in an effort to better understand the contributions of symbiotic microbes to the biology of Reticulitermes flavipes, the eastern subterranean termite. Lower-termites, like R. flavipes, house symbionts from all three domains of life within their hindgut paunch. This intimate association is reflected in nearly every aspect of termite biology. Here, I investigate these physiological collaborations as they relate to digestion and immunity. My efforts focused on 1) quantifying the role of bacteria in wood digestion within the termite gut, 2) evaluating the role of symbionts in protection against pathogens, and 3) identifying gene products that bacterial …

Ross River Virus Runs Rampant On The Gold Coast Of Australia, Brandon Gerhart

Midsouth Entomologist

The first outbreak of Ross River Virus (RRV) occurred in 1928 in South Wales, Australia. I reviewed RRV literature published between 2001 and 2015. The virus is carried by a mosquito and transmitted through a wallaby as its most common intermediate host. Researchers arrived at their findings by conducting extensive lab work on both mosquitos and humans. Signs and symptoms of RRV include joint inflammation, pain, fatigue, and muscle aches. It takes 3-21 days for symptoms to appear, with an average of 9 days. There is no cure to RRV, and there is no vaccine currently being developed. The best …

Cryptosporidium Parvum: Is It Invincible?, Caitlin Wonnacott

Midsouth Entomologist

Cryptosporidium is a coccidian protozoan parasite that can affect mammals, reptiles, and birds. A coccidian is a single-celled protozoan that affects the epithelial lining of the intestinal walls of hosts it parasitizes. This parasite has a unique life cycle and can withstand common measures of sterilization. The infective oocyte stage is resistant and hardy. It takes on two forms where each goes to different places within the host. Contamination of water sources has led to large outbreaks of cryptosporidiosis, even though the water met and passed the standards for drinking water. Conclusions from previous studies will help lead the way …

What Is Leishmaniasis?, Kimberly Wilson

Midsouth Entomologist

Leishmaniasis is a parasitic disease that can cause painful sores to cover one's body. It is found in parts of the tropics, subtropics, and southern Europe. Leishmaniasis is caused by infection with a complex of protozoan organisms, Leishmania spp, which are spread by the bite of infected phlebotomine sand flies (Diptera: Psychodidae). There are several different forms of leishmaniasis in people. The most common are cutaneous and visceral. The cutaneous type causes skin sores. The visceral type affects internal organs like the spleen, liver, and sometimes bone marrow.

Antibody Titers To Bed Bug Salivary Proteins In Chickens From An Infested Broiler Breeder House, J. Goddard, J. S. Portugal, K. Maschek

Midsouth Entomologist

Bed bugs (Hemiptera: Cimicidae) might be significant pests in poultry operations, especially in broiler breeder houses. In this study, chickens in breeder houses, known to be infested with bed bugs, demonstrated antibodies to bed bug salivary gland extract, while those not exposed to bed bugs, did not. Antibody titers ranged from 1:160 to 1:640. These results document for the first time that chickens in commercial production, when exposed to bed bug biting, produce antibody responses to proteins contained in bed bug saliva.

2015 Soybean Insect Losses In The Southern Us, F. R. Musser, A. L. Catchot Jr., J. A. Davis, D. A. Herbert Jr., G. M. Lorenz, T. Reed, D. D. Reisig, S. D. Stewart

Midsouth Entomologist

Survey-based soybean insect losses were collected following the 2015 growing season to provide a record of insect pressure and soybean management practices for the year. This survey has been done annually in all participating states for at least the last 5 years and since 2004 in Mississippi. The 2015 survey represents 11.7 million soybean acres across the southern United States. Overall, stink bugs re-emerged as the most expensive pest in soybean followed closely by corn earworm and soybean looper. The proportion of fields planted with insecticide seed treatments decreased slightly for the second consecutive year to 60% of all acreage. …

Chikungunya: An Imminent Threat To The United States, Breanna Lyle

Midsouth Entomologist

Recent years have seen a drastic increase in the number of cases of Chikungunya, a mosquito-vectored disease spread by day-feeding mosquitoes in the genus Aedes (Diptera: Culicidae). Cases of this disease have been on the rise in the Caribbean Islands as well as in many South American countries. The presence of the vector in many parts of the United States, as well as the proximity to these cases make Chikungunya a looming threat to the United States. While this disease is rarely considered a lethal one, the lasting impacts of an outbreak would be significantly detrimental to the infrastructure of …

Primary Amoebic Meningoencephalitis (Pam) - Deadly Waters, Morgan Hommel

Midsouth Entomologist

Naegleria fowleri Carter, is a protozoan that causes Primary Amoebic Meningoencephalitis (PAM). Naegleria fowleri is also referred to as the "brain-eating amoeba", due to the fact that it destroys the brain when in contact. PAM is an extremely rare, yet fatal disease. Fewer than 5 percent of people that have had PAM have survived. PAM is in the United States as well as in underdeveloped countries, most recently Pakistan. PAM is avoidable, as long as the contaminated water does not enter the nostrils.

Visual, Vibratory, And Olfactory Cues Affect Interactions Between The Red Spider Mite Tetranychus Evansi And Its Predator Phytoseiulus Longipes, Ginette Yèyinou Azandémè-Hounmalon, Baldwyn Torto, Komi Kouma Mokpokpo Fiaboe, Sevgan Subramanian, Serge Kreiter, Thibaud Martin

All Peer-Reviewed Publications

Phytoseiulus longipes Evans (Mesostigmata: Phytoseiidae) is an exotic predator widely used in biological control programs for the red spider mite Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae) in East Africa. However, little is known about the cues mediating this prey/predator interaction. Here, we performed behavioral assays to test the involvement of visual, vibratory, and olfactory cues using a combination of dead/living insects enclosed in either perforated or non-perforated transparent/opaque capsules. We monitored insect responses with a video tracking system and analyzed the data with Ethovision software. Our results showed avoidance behavior of T. evansi in the presence of live P. …

Impact Assessment Of Integrated Pest Management (Ipm) Strategy For Suppression Of Mango-Infesting Fruit Flies In Kenya, Beatrice W. Muriithi, Hippolyte D. Affognon, Gracious M. Diiro, Sarah W. Kingori, Chrysantus M. Tanga, Peterson W. Nderitu, Samira A. Mohamed, Sunday Ekesi

All Peer-Reviewed Publications

We utilized two waves of data collected from a sample of mango farmers in Meru County in Kenya to evaluate the impact of Integrated Pest Management (IPM) strategy for controlling fruit flies in mango-production. We specifically explored the effect of five IPM practices including parasitoids (p) and Metarhizium anisopliae-based biopesticides (biop), orchard sanitation (os), spot spray of food bait (fb) and male annihilation technique (mat) on three outcome indicators: farmer pesticide expenditure, farm-level mango fruit yield losses and profit. We fitted difference-in-difference and household fixed effects regression models that account for unobserved heterogeneity across households. Our estimates differentiated the impact …

Choreography Of Silk Spinning By Webspinners (Insecta: Embioptera) Reflects Lifestyle And Hints At Phylogeny, David Mcmillan, Kyle Hohu, Janice Edgerly-Rooks

Biology

Silk spinning defines the morphologically constrained embiopterans. All individuals spin for protection, including immatures, adult males and the wingless females. Enlarged front tarsi are packed with silk glands and clothed with ejectors. They spin by stepping with their front feet and releasing silk against substrates and onto preexisting silk, often cloth-like. Spinning is stereotypical and appears to differ between species in frequency and probability of transition between two spin-step positions. This spinning choreography was assessed using thousands of spin-steps scored in the laboratory for 22 species to test: (1) the body size hypothesis predicting that spinning would be more complex …
