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.

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 ...

Dragonfly (Odonata: Corduliidae, Macromiidae, Gomphidae, Aeshnidae) And Damselfly (Odonata: Calopterygidae) Exuviae Observed At Record Heights In Pinus Strobus And Picea Abies Canopies, Madison M. Laughlin, Jonathan G. Martin, Patrick J. Liesch, Erik R. Olson

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 ...

An Inventory Of Cicadellidae, Aphrophoridae, And Delphacidae (Hemiptera) In The Alvar Grasslands Of The Maxton Plains, Michigan, Max W. Spencer, James P. Dunn, Evan M. Szymczak

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 ...

Pentatomidae (Hemiptera: Heteroptera: Pentatomidae) Captured On Purple Prism Traps Deployed For Detection Of Emerald Ash Borer (Agrilus Planipennis) (Coleoptera: Buprestidae) In Minnesota, Daniela T. Pezzini, Mitch Haag, James Walker, Robert L. Koch

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 ...

Intercepted Silvanidae [Insecta: Coleoptera] From The International Falls, Mn [Usa] Port-Of-Entry, Gary D. Ouellette

The Great Lakes Entomologist

Silvanidae species recorded in association with imported commodities, at United States ports-of-entry, have not been comprehensively studied. The present study examines the species of beetles of the family Silvanidae intercepted during agricultural quarantine inspections at the International Falls, MN port-of-entry. A total of 244 beetles representing two subfamilies, three genera, and four species of Silvanidae were collected between June 2016 and June 2017. Taxa were associated with 13 imported commodities and recorded from seven countries of origin. A substantial proportion (97.4%) of the records included Silvanus lewisi Reitter and Ahasverus advena (Waltl), two cosmopolitan species associated with dried stored ...

Characterization Of The Natural Enemy Community, With Emphasis On Entomopathogens, For Management Of Western Corn Rootworm (Diabrotica Virgifera Virgifera) In West Central Nebraska, Camila Oliveira-Hofman

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 ...

Gut Symbiont Viability In Honey Bees Exposted To Agrochemical Stressors, Bryant Justin Gabriel

Dissertations and Student Research in Entomology

The honey bee gut microbiome is essential for protecting this pollinator against abiotic and biotic stressors, including the prevention of harmful gut parasites and pathogens. Previous studies have not only demonstrated a linkage of bee gut dysbiosis to increased immunodeficiencies and pathogen sensitivities, but also report the maladaptation of the gut microbiome in bees exposed to agricultural and apicultural chemistries. There are few techniques available that allow for a simple and reliable analysis of the relative proportions of live and dead gut microbes in bees exposed to these chemistries. Previous techniques for measuring gut symbiont dysbiosis are temporally limited by ...

Effects Of Neem On Plasmatocyte Counts In Galleria Mellonella Larvae, Michael Anthony Fenske

MSU Graduate Theses

The neem tree (Azadirachta indica) has been called the tree of the 21^st century, due to its many beneficial properties. This research studies the effects of neem products on plasmatocytes of Galleria mellonella larvae challenged by injections of Sumi ink. Counts of circulating plasmatocytes increased in response to the ink within 4 hours. Concurrent injections of neem essential oil reversed this process in a dose-dependent manner. Methanolic extracts of neem essential oil had similar effects on counts of circulating plasmatocytes mobilized by ink injections. Aqueous extracts from neem bark did not have effects on plasmatocyte counts. Comparative high-performance thin ...

Competition Among Three Forensically Important Blow Fly Species (Diptera: Calliphoridae): Phormia Regina, Lucilia Sericata, And Chrysomya Rufifacies, Amber Macinnis

Dissertations & Theses in Natural Resources

The aim of this study was to use interspecific competition between three species of blow flies (Diptera: Calliphoridae) to determine if interspecific competition might explain the successional patterns. A replacement series model was used for three species of blowflies: Phormia regina, Lucilia sericata, and Chrysomya rufifacies. A total of 20 maggots were used for each treatment and the proportion of each species was varied. The graphic evidence and the relative crowding coefficient of P. regina versus L. sericata indicated a significant competitive advantage of P. regina. One of the life history traits of L. sericata is that it oviposits on ...

Co-Dependency Between A Specialist Andrena Bee And Its Death Camas Host, Toxicoscordion Paniculatum, James H. Cane

All PIRU Publications

Among associations of plants and their pollinating bees, mutually specialized pairings are rare. Typically, either pollen specialist (oligolectic) bees are joined by polylectic bees in a flowering species’ pollinator guild, or specialized flowers are pollinated by one or more polylectic bees. The bee Andrena astragali is a narrow oligolege, collecting pollen solely from two nearly identical species of death camas (Toxicoscordion, formerly Zigadenus). Neurotoxic alkaloids of these plants are implicated in sheep and honey bee poisoning. In this study, T. paniculatum, T. venenosum and co-flowering forbs were sampled for bees at 15 sites along a 900-km-long east–west transect across ...
