Montview Liberty University Journal of Undergraduate Research
Microbes play a significant role in ecosystems, effecting the vital functions of other organisms, interspecies relationships, and population sizes. Based upon previous research (Skelton et al., 2016), it has been hypothesized that crayfish symbionts (branchiobdellidans) play a significant role in regulating the amount of microbiota associated with the host. A growing body of knowledge is known regarding both the condition of gill fouling and the annelid worm’s symbiotic relationship with the crayfish (Skelton et al., 2016; Skelton et al., 2016). However, there is little to no evidence available concerning the bacteria’s role in the process (Skelton et al ...

Acarine Biodiversity In Ecuador: Two New Species Of Endoparasitic Chiggers (Acarina: Trombiculidae) From Terrestrial Andean Anurans, Ricardo Guerrero, Mario Humberto Yánez-Muñoz
MANTER: Journal of Parasite Biodiversity
Two species of endoparasitic chiggers, Vercammenia neotropica n. sp. and Microtrombicula ecuadorensis n. sp., are described, both found in terrestrial anurans of the genus Pristimantis collected in the Andes of Ecuador. A new combination is proposed for Trombicula yorkei Sambon, 1928 as Microtrombicula yorkei (Sambon, 1928) n. comb., and Schoengastia lynni Ewing, 1942 is placed as incertae sedis. This is the first record of species of the genus Vercammenia in the Neotropical region.

Mechanisms Underlying Freeze Tolerance In The Spring Field Cricket, Gryllus Veletis, Jantina Toxopeus
Electronic Thesis and Dissertation Repository
Freeze tolerance has evolved repeatedly across insects, facilitating survival in low temperature environments. Internal ice formation poses several challenges, but the mechanisms that mitigate these challenges in freeze-tolerant insects are not well understood. To better understand how insects survive freezing, I describe a novel laboratory model, the spring field cricket Gryllus veletis (Orthoptera: Gryllidae). Following acclimation to six weeks of decreasing temperature and photoperiod (mimicking autumn), G. veletis juveniles becomes moderately freeze-tolerant, surviving freezing at -8 °C for up to one week, and surviving temperatures as low as -12 °C. Acclimation is associated with increased control of the temperature and ...

Wild, Native Bees And Managed Honey Bees Benefit From Similar Agricultural Land Uses, Elaine Evans, Matthew Smart, Dan Cariveau, Marla Spivak
Faculty Publications: Department of Entomology
Although both managed and unmanaged bees are important pollinators of crops and wild plants, efforts to address questions about landscapes that best support pollinators often focus on either wild pollinators or honey bees. This study examined if there was concordance between the success of wild bee communities and managed honey bee colonies at sites varying in floral availability and disturbance level in a predominantly agricultural landscape. We also determined which agricultural land uses best supported wild bee communities. The study area in the state of North Dakota in Northern Great Plains in North America is home to understudied native bee ...

Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese
Honors Scholar Theses
The Chrysoperla carnea-group of green lacewings is a cryptic species complex. Species within the group are morphologically similar, yet isolated from one another via reproductive mating song. Chrysoperla zastrowi, a species within the carnea-group, is currently described with a distribution ranging from South Africa to the Middle East and India. However, recent collections of carnea-group lacewings from Guatemala and California were preliminarily identified as Chrysoperla zastrowi based upon similarities in their vibrational courtship songs. This analysis aims to place six specimens, collected by collaborators in Guatemala, Armenia, Iran, and California, into a pre-existing phylogeny of the Chrysoperla ...

The Effects Of Juvenile Exposure To Sub-Lethal Concentrations Of Pesticides On The Adult Reproductive Biology Of The Male Southern House Mosquitoe, Culex Quinquefasciatus, Shiloh Dean Judd
LSU Master's Theses
Mosquitoes transmit pathogens capable of causing significant diseases, the worst of which can permanently disfigure or kill. Mosquito control efforts can be strengthened by better understanding all aspects of mosquito biology, but there is deficient information regarding sperm production in male mosquitoes. Understanding the sperm production and capacity of vector species may reveal new control strategies.
The goal of this research was to determine if larval exposure to sub-lethal concentrations, defined as killing less than half of the sample population, of pesticides negatively impacts the adult male reproductive health of the southern house mosquito, Culex quinquefasciatus Say. This study quantified ...

Novel Prey Record For Scymnus Caudalis Leconte And First Records Of Four Other Species Of Coccinellidae (Coleoptera) In Wisconsin, U.S.A., Louis S. Hesler, Jedidiah Nixon
The Great Lakes Entomologist
New prey and distribution records are presented for five species of lady beetles (Coleoptera: Coccinellidae). Scymnus (Pullus) caudalis LeConte is recorded for the first time preying on Aphis asclepiadis Fitch (Hemiptera: Aphididae). Four other lady beetle species are newly recorded in the state of Wisconsin, U.S.A: Diomus amabilis (LeConte), Diomus terminatus Say, Scymnus (Pullus) uncus Wingo, and Hyperaspidius wolcotti (Nunenmacher). The new state records represent minor to moderate extensions of previously known geographic distributions for these species. In addition, the records emphasize the importance of processing uncurated zoological specimens to provide information about the prey of particular species ...

The Great Lakes Entomologist
Most odonate species do not typically climb higher than 50 cm when choosing an emergence support. We observed multiple species of odonate nymphs using trees as emergence supports at heights greater than 50 cm and up to 4, 6.9, and 14.6 m for Calopteryx maculata (Ebony Jewelwing), Somatochlora minor (Ocellated Emerald), and Didymops transversa (Stream Cruiser), respectively. These heights represent the greatest heights ever documented for odonate nymphs emergence supports. Our research suggests that some species (S. minor; D. transversa) appear to have a greater affinity for climbing to great heights during emergence than others (Dromogomphus spinosus (Black-Shouldered ...

The Great Lakes Entomologist
Alvars are rare grassland communities found in the North American Great Lakes Region consisting of thin mineral soil over limestone bedrock and act as refugia for many unique and threatened endemic species. Few studies have catalogued Hemiptera species present in the alvars of the Maxton Plains on Drummond Island, MI. We aimed to add to these species lists, compare species diversity between alvar sites with varying levels of exposed bedrock, and test if an unpaved limestone road running through our sample sites influenced Hemipteran populations. We collected several prairie endemic species of Cicadellidae (Hemiptera), including a new record for the ...

The Great Lakes Entomologist
The observation of bycatch from insect trapping programs, though often considered bothersome, may hold value for ecological and taxonomic studies. In Minnesota, a large trapping survey consisting of pheromone-baited purple prism traps, has been conducted for early detection of Agrilus planipennis, the emerald ash borer. Stink bugs (Heteroptera: Pentatomidae), which are pests of increasing importance in the North Central U.S., were observed to be captured by these traps. The objective of this study was to use trap bycatch from the A. planipennis traps for further documentation of the abundance and diversity of Pentatomidae in Minnesota. In 2011 and 2012 ...

Japanese Beetles’ Feeding On Milkweed Flowers May Compromise Efforts To Restore Monarch Butterfly Habitat, Adam M. Baker, Daniel A. Potter
Entomology Faculty Publications
The eastern North American migratory population of monarch butterflies (Danaus plexippus) is in serious decline. Habitat restoration, including adding millions of host plants to compensate for loss of milkweed in US cropland, is a key part of the international conservation strategy to return this iconic butterfly to sustainable status. We report here that Popillia japonica, a polyphagous, invasive beetle, aggregates and feeds on flowers of Asclepias syriaca, the monarch’s most important larval food plant, reducing fruiting and seed set by >90% and extensively damaging milkweed umbels in the field. The beetle’s ongoing incursion into the monarch’s key ...

Double-Stranded Rna Binding Protein, Staufen, Is Required For The Initiation Of Rnai In Coleopteran Insects, June-Sun Yoon, Kanakachari Mogilicherla, Dhandapani Gurusamy, Xien Chen, Shankar C. R. R. Chereddy, Subba R. Palli
Entomology Faculty Publications
RNA interference (RNAi) is being used to develop methods to control pests and disease vectors. RNAi is robust and systemic in coleopteran insects but is quite variable in other insects. The determinants of efficient RNAi in coleopterans, as well as its potential mechanisms of resistance, are not known. RNAi screen identified a double-stranded RNA binding protein (StaufenC) as a major player in RNAi. StaufenC homologs have been identified in only coleopteran insects. Experiments in two coleopteran insects, Leptinotarsa decemlineata and Tribolium castaneum, showed the requirement of StaufenC for RNAi, especially for processing of double-stranded RNA (dsRNA) to small interfering RNA ...

Dissertations and Student Research in Entomology
Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae),the western corn rootworm (WCR), is a major pest of corn (Zea mays L.) in the United States and Europe. WCR management options comprise mainly transgenic hybrids, insecticide applications and crop rotation. WCR is highly adaptable to management practices and field-evolved resistance to transgenic corn, insecticides and crop rotation in the United States Corn Belt has been reported. Therefore, the motivation for this project was to look into alternative options for WCR management. The goal of this dissertation is to characterize the natural enemies from irrigated commercial cornfields in Nebraska and examine their potential ...
