Investigating the transmission of epizootic hemorrhagic disease virus (EHDV) among white-tailed deer in Alabama

Zhang, Xinmi (2017-04-19)

Epizootic hemorrhagic disease virus (EHDV) is an arbovirus that mostly cycles between white-tailed deer and biting midges of the genus Culicoides. EHDV infections can be fatal for white-tailed deer and occasionally cause ...

Investigation and Characterization of Antibacterial Proteins from the Eastern Subterranean Termites Reticulitermes flavipes in Response to Multidrug Resistant Bacteria

Zeng, Yuan (2017-04-20)

Immune system of insects has been of great interest for discovering novel compounds against microbes. Subterranean termites (Blattodea: Isoptera: Rhinotermitidae), especially the Reticulitermes species, have a wide ...

Molecular Mechanisms of Cytochrome P450 Monooxygenase-Mediated Pyrethroid Resistance in the House Fly, Musca domestica (L.)

Zhu, Fang (2007-08-15)

A wild-type pyrethroid resistant house fly strain, ALHF, was collected from a poultry farm in Alabama after control failure with permethrin (a pyrethroid insecticide). It was further selected with permethrin for 6 generations ...

Molecular Mechanisms of Pyrethroid Resistance in the Mosquito, Culex quinquefasciatus (Say)

Xu, Qiang (2007-08-15)

Mosquitoes have been the ideal transmitters of a wide variety of disease agents due to their repeated blood feedings over their life span. Culex quinquefasciatus (Say) is an important disease vector in the Southeastern ...

Molecular Responses of Giardia lamblia to Gamma-Irradiation

Lenaghan, Scott (2008-08-15)

Giardia lamblia (syn intestinalis, syn duodenalis) is an important human pathogen and the etiological agent of giardiasis, the most common gastrointestinal disease in the world. Since its discovery in 1681, Giardia has ...

Multiple Mechanisms of Permethrin Resistance in the Southern House Mosquito, Culex quinquefasciatus

Li, Ting (2013-07-18)

The inherited resistance to permethrin in Culex quinquefasciatus, which is the primary vector of encephalitis and lymphatic filariasis pathogens, resulted from the molecular basis of multiple mechanisms involved in changes ...

Nutritional Ecology of Pseudacteon species (Diptera: Phoridae) and Its Impact on Their Fitness

Ajayi, Olufemi (2015-07-24)

Natural enemies, such as Pseudacteon parasitic flies, have the potential to provide sustainable suppression of imported fire ants, Solenopsis species. Multiple releases of various species of these flies have been made ...

Olfactory Responses and Odor Coding of Culex quinquefasciatus to Human Odorants

Ye, Zi (2015-07-21)

The southern house mosquito, Culex quinquefasciatus (Diptera: Culicidae), transmits a number of potentially fatal diseases, including West Nile virus (WNV). From 1999 to 2013, WNV caused 39,557 cases of human infection and ...

Phenology of Pseudacteon spp. (Diptera: Phoridae) flies in Alabama

Palmer, Kelly (2014-12-10)

Phorid flies, Pseudacteon spp. (Diptera: Phoridae), are one of many biological control agents of Solenopsis spp. (Hymenoptera: Formicidae) fire ants in their native South America. More than twenty species of phorid flies ...
