Creating a routing backbone is a fundamental problem in both biology and engineering. The routing backbone of the trail networks of arboreal turtle ants (Cephalotes goniodontus) connects many nests and food sources using trail pheromone deposited by ants as they walk. Unlike species that forage on the ground, the trail networks of arboreal ants are constrained by the vegetation. We examined what objectives the trail networks meet by comparing the observed ant trail networks with networks of random, hypothetical trail networks in the same surrounding vegetation and with trails optimized for four objectives: minimizing path length, minimizing average …

School of Earth & Environment Departmental Research
Tiger beetles are a popular group of insects amongst amateur naturalists, and are well-represented in museum and private collections. New species descriptions plateaued in the 19th century, but there is a recent resurgence of discoveries as integrative taxonomy methods, guided by molecular systematics, uncover “cryptic” tiger beetle diversity. In this paper, we describe a new species using multiple data types. This new species, Eunota mecocheila Duran and Roman n. sp., is in the tribe Cicindelini, and is described from specimens collected in saline muddy ditches in northern Mexico. This species is closely related to E. circumpicta (LaFerté-Sénectère, 1841), but is …

Mosquitoes are the most terrifying both for their abundance and for the diseases they transmit. They are vectors of malaria, lymphatic filariasis and arbovirus such as yellow fever, dengue, viral encephalitis and African horse sickness. These characteristics give this fauna prominent importance and health interest. To identify the most widespread mosquito species, we conducted for the first time an inventory in the Aures region more particularly the wilaya of Batna (East of Algeria) from May 2017 to January 2020, we studied their diversity, abundance and distribution. The sampling is done by monthly surveys of the various localities chosen, using the …

The Sterile Insect Technique (SIT) is a successful autocidal control method that uses ionizing radiation to sterilize insects. However, irradiation in normal atmospheric conditions can be damaging for males, because irradiation generates substantial biological oxidative stress that, combined with domestication and mass-rearing conditions, may reduce sterile male sexual competitiveness and quality. In this study, biological oxidative stress and antioxidant capacity were experimentally manipulated in Anastrepha suspensa using a combination of low-oxygen conditions and transgenic overexpression of mitochondrial superoxide dismutase (SOD2) to evaluate their role in the sexual behavior and quality of irradiated males. Our results showed that SOD2 overexpression enhances …

A Review Of The History Of The Names Hamaticherus Dejean And Plocaederus Dejean And Description Of A New Genus And Species (Coleoptera: Cerambycidae: Cerambycinae), Antonio Santos-Silva, Kimberly García, Juan Pablo Botero
Insecta Mundi
Hamaticherus Dejean, 1821 (Coleoptera: Cerambycidae: Cerambycinae) is considered a junior synonym of Cerambyx Linnaeus, 1758. Hamaticherus sensu Audinet-Serville, 1834 is considered a posterior usage of Hamaticherus Dejean, 1821, and an unavailable name. Plocaederus is considered as a new genus, and not a replacement name, proposed by Dejean (1835) to allocate the species included in Hamaticherus sensu Audinet-Serville, 1834. Therefore, a new genus, Hamaederus Santos-Silva, Garcia and Botero, is herein proposed to include the species currently allocated in Plocaederus Dejean, 1835, creating 15 new combinations, and additionally, a new species from French Guiana, Hamaederus allofasciatus Santos-Silva, Garcia and Botero, …
First Reports Of Species-Specific Ant Resemblance In Heteronotine Treehoppers (Hemiptera: Membracidae: Heteronotinae), Robert Perger
First Reports Of Species-Specific Ant Resemblance In Heteronotine Treehoppers (Hemiptera: Membracidae: Heteronotinae), Robert Perger
Insecta Mundi
Species-specific ant resemblance in heteronotine membracids (Hemiptera: Membracidae) is reported for the first time, providing evidence for ant mimicry. The shape, integument color and shine of the pronotal process of females of Heteronotus fabulosus Boulard closely resemble workers of the co-occurring giant turtle ant Cephalotes atratus (Linnaeus) (Hymenoptera: Formicidae). The entire membracid appears to mimic a mutualistic relationship between a membracid and a turtle ant.
The treehopper family Membracidae Rafinesque, 1815 is famous among entomologists for their mutualistic relationships with hymenopterans (Way 1963) and high morphological diversity of their pronotum, often consisting of brightly colored and/or curiously shaped structures such …

Insect seminal fluid, the non-sperm component of the ejaculate, comprises a variegated set of molecules, including, but not limited to, lipids, proteins, carbohydrates, salts, hormones, nucleic acids, and vitamins. The identity and functional role of seminal fluid proteins (SFPs) have been widely investigated, in multiple species. However, most of the other small molecules in insect ejaculates remain uncharacterized. Metabolomics is currently adopted to deepen our understanding of complex biological processes and in the last 15years has been applied to answer different physiological questions. Technological advances in high-throughput methods for metabolite identification such as mass spectrometry and nuclear magnetic resonance (NMR) …

Egg Plastron Of The Bog Copper Butterfly Tharsalea (Epidemia) Epixanthe (Bsd. & Le C. [1835]) (Lycaenidae: Lycaeninae), David M. Wright
The Taxonomic Report of the International Lepidoptera Survey
The egg of the Bog Copper butterfly, Tharsalea (Epidemia) epixanthe, has a prominent highly-sculptured chorionic surface. Trapped within the chorion is a labyrinth of air spaces which has been proposed as a plastron for gas exchange while the egg is submerged in water. Data derived from scanning electron microscopy (SEM) confirms the plastron should function as predicted. Furthermore, the insulating air spaces should prevent water loss of the diapausing first instar larvae while overwintering.

Molecular Characterization Of Western Corn Rootworm Pyrethroid Resistance, Dariane Souza, Blair D. Siegfried, Lance Meinke, Nicholas J. Miller
Department of Entomology: Faculty Publications
Background: Western corn rootworm (WCR) pyrethroid resistance has been confirmed in the western US Corn Belt. Toxicological and biochemical studies indicated that multiple mechanisms of resistance might be involved in the resistance trait, such as enhanced metabolism and/or kdr target-site mutation(s) in the voltage-gated sodium channels. To characterize the mechanisms of WCR pyrethroid resistance at the molecular level, pairwise comparisons were made between RNA-Seq data collected from pyrethroid-resistant and -susceptible WCR populations. Gene expression levels and sodium channel sequences were evaluated.
Results: Seven transcripts exhibited significantly different expression (q ≤ 0.05) when comparing field-collected pyrethroidresistant (R-Field) and -susceptible (S-Field) WCR …

Effect Of Moisture Stress On The Development Of False Codling Moth Thaumatotibia Leucotreta (Lepidoptera: Tortricidae) On Two Tomato Varieties, Esther Museo Patrick, Irene Koomen, Shepard Ndlela, John Mwibanda Wesonga
All Peer-Reviewed Publications
False codling moth Thaumatotibia leucotreta (Meyrick) is a pest native to sub-Saharan Africa infesting over 100 plant species including tomato. Its survival and performance are influenced by changes in precipitation and stress-related biochemical changes in the host plant. Water availability for agricultural production continues to decline due to climate change affecting drought-sensitive crops like tomatoes. Little is known on host plant–insect interactions of T. leucotreta and tomato as influenced by moisture stress. Hence, our study tested the impact of different water holding capacities (WHC) (40%, 50%, 60%, 70%, and 90%) of plant growing media on the growth of Anna F1 …

In the Eastern Africa highlands, the gradual transformation of natural ecosystems to smallholding coffee-based agrosystems has resulted in more fragmented landscapes. Major pests of coffee find appropriate living conditions leading to high infestation rates and the need for smallholder farmers to implement pest control measures. This study aims to understand the influence of landscapes on the ecology of three major coffee pests: the coffee berry borer (CBB), Hypothenemus hampei, and the Antestia bugs Antestiopsis thunbergii (ABT) and A. facetoides (ABF). The study was conducted on a typical smallholder coffee-based landscape in central Kenya. The pest abundance was assessed monthly for …

Invasion of ecosystems by alien species is a global concern. Robinia pseudoacacia L. (Fabaceae) is one such species which impacts on native diversity and ecosystem functioning. We assessed how R. pseudoacacia affects flower visitation by arthropods in commercial apple orchards in eastern Free State, South Africa. We used paired observations to compare the abundance and diversity of flower visitors and their interactions with the two plant species. Our results showed that R. pseudoacacia flowers attract African honey bees (Apis mellifera) more than apple flowers. However, flower visitation by Diptera, particularly March flies (Bibionidae) was higher in apple flowers. Arthropods of …

Intracellular effects exerted by phytochemicals eliciting insect growth-retarding responses during vector control intervention remain largely underexplored. We studied the effects of Zanthoxylum chalybeum Engl. (Rutaceae) (ZCE) root derivatives against malaria (Anopheles gambiae) and arbovirus vector (Aedes aegypti) larvae to decipher possible molecular targets. We report dose-dependent biphasic effects on larval response, with transient exposure to ZCE and its bioactive fraction (ZCFr.5) inhibiting acetylcholinesterase (AChE) activity, inducing larval lethality and growth retardation at sublethal doses. Half-maximal lethal concentrations (LC50) for ZCE against An. gambiae and Ae. aegypti larvae after 24-h exposure were 9.00 ppm and 12.26 ppm, respectively. The active fraction …

Olfaction plays an important role in the behavioural ecology of the desert locust Schistocerca gregaria (Orthoptera:Acrididae). Different locust life stages and sexes use olfactory cues for different behaviours such as grouping, mating, oviposition, feeding, maturation and gregarization, which can be exploited for management of the desert locust. However, the full spectrum of the chemistry of volatiles released by the desert locust remains unknown. Here, we compared the volatile emissions of different life stages of a natural wild population reared in the laboratory for one generation with those of a population that has been reared in the laboratory for seven generations. …

In the past few decades, the control of pests and diseases of cultivated plants using natural and biological measures has drawn increasing attention in the quest to reduce the level of dependence on chemical products for agricultural production. The use of living organisms, predators, parasitoids, and microorganisms, such as viruses, bacteria, and fungi, has proven to be a viable and sustainable pest management technique. Among the aforementioned, fungi, most importantly the insect-pathogenic species, have been in use for more than 150years. These include the most popular strains belonging to the genera Beauveria, Metarhizium, Isaria, Hirsutella, and Lecanicillium. Their application is …

Wildflower Pollen Quality In Roadside Habitats, With Particular Emphasis On Hedera Helix, Aoife Mcmullin, Paul Hamilton
SURE Journal: Science Undergraduate Research Experience Journal
The quality of air is of more significance today than ever before. Human population growth and pollutants emitted through fossil fuel consumption put pressures on air quality. It is widely acknowledged that atmospheric pollutants negatively impact human health; the same is also true for the health of wildlife and plants exposed to these pollutants (Brunekreef & Holgate, 2002; EEA, 2019; Schiavoni, et al., 2017). Pollen and seed formation of flowering plants have been affected when grown in areas of poor air quality (Azzazy, 2016; Sénéchal, et al., 2015). The purpose of this research was to assess pollen of …

Globally, the expansion of livestock and fisheries production is severely constrained due to the increasing costs and ecological footprint of feed constituents. The utilization of black soldier fly (BSF) as an alternative protein ingredient to fishmeal and soybean in animal feed has been widely documented. The black soldier fly larvae (BSFL) used are known to voraciously feed and grow in contaminated organic wastes. Thus, several concerns about their safety for inclusion into animal feed remain largely unaddressed. This study evaluated both culture-dependent sequence-based and 16S rDNA amplification analysis to isolate and identify bacterial species associated with BSFL fed on chicken …
Insect Developmental Plasticity: The Role In A Changing Environment, Lindsey A. Barnes
Insect Developmental Plasticity: The Role In A Changing Environment, Lindsey A. Barnes
The Cardinal Edge
Climate change has been recognized as a severe threat to biodiversity. In the rapidly growing collection of literature on the consequences of global change, researchers have recently noticed a dramatic decrease in insect populations in a wide range of habitats. Insects are extremely susceptible to climatic change, especially with regard to fluctuations in moisture and temperature. However, insects often exhibit phenotypic plasticity, where organisms will express different phenotypes when presented with a specific environmental stimulus. In developmental plasticity, environmental stimuli at the larval stage can determine adult phenotypes. This review focuses on case studies of developmental plasticity in insects, with …

Nonnative pests and pathogens severely affect forest health and are often spread in firewood. Our objectives were to create an extension education program using “Don’t Move Firewood”-themed geocaches and travel bugs which were placed near campgrounds across Mississippi, and to assess the efficiency and effectiveness of this outreach method. Interactions with caches and travel bugs were monitored over nearly one year and summarized to provide a measure of outreach success. With a one-time per-unit cost of $45.95 for caches and $6.75 for travel bugs, these tools provide ongoing, cost-effective educational approaches well suited to augment existing or launch new outreach …

Host-pathogen interactions are central components of ecological networks where the MAPK signaling pathways act as central hubs of these complex interactions. We have previously shown that an insect hormone modulated MAPK signaling cascade participates as a general switch to trans-regulate differential expression of diverse midgut genes in the diamondback moth, Plutella xylostella (L.) to cope with the insecticidal action of Cry1Ac toxin, produced by the entomopathogenic bacterium Bacillus thuringiensis (Bt). The relationship between topology and functions of this four-tiered phosphorylation signaling cascade, however, is an uncharted territory. Here, we carried out a genome-wide characterization of all the MAPK orthologs …
Resistance Allele Frequencies To Cry1ab And Vip3aa20, And Performance Of Cry1a.105/Cry2ab2 Susceptible And Single/Dual-Gene Resistant Corn Earworm On Non-Bt And Low Concentrations Of Bt Diet, Shucong Lin
LSU Master's Theses
Corn earworm, Helicoverpa zea (Boddie), is an important agricultural pest and a target species of Bt corn and Bt cotton. Recently, this pest in the U.S. has developed resistance to Cry1/Cry2 corn and cotton. The objectives of this study were to 1) estimate the frequencies of resistance allele to Cry1Ab and Vip3Aa20 proteins in Louisiana populations of H. zea; 2) determine if Cry1A.105/Cry2Ab2 single/dual-gene resistance in H. zea is associated with fitness costs; and 3) investigate the effect of three low concentrations of mixed Cry1A.105/Cry2Ab2 proteins on the growth, development, and reproduction of two known Bt-susceptible strains and six …
