Horizontal transfer of genes and genomes in an endosymbiotic system: Investigation of the movement of intracellular bacteria and related gene transfer
DownloadFall 2013
The genus Wolbachia is comprised of intracellular gram negative bacteria capable of infecting a wide range of insect hosts. In arthropods, Wolbachia are reproductive parasites that can cause cytoplasmic incompatibility, parthenogenesis, feminization or male killing, each of which enhances the...

The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoids
DownloadFall 2010
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...

The use of lysozyme-HCl and nisin to control the causal agent of chalkbrood disease (Ascosphaera apis (Maassen ex Claussen) Olive and Spiltoir) in honey bees (Apis mellifera L.)
DownloadFall 2010
Chalkbrood, caused by Ascosphaera apis (Maassen ex Claussen) Olive & Spiltor, is a cosmopolitan fungal disease of honey bee larvae (Apis mellifera L.) for which there is no chemotherapeutic control. Using in vitro larval rearing methods, lysozyme-HCl, a food-grade antimicrobial extracted from hen...

Unique cellular interactions between the obligate intracellular bacteria Wolbachia pipientis and its insect host
DownloadFall 2011
Wolbachia are maternally inherited obligate intracellular bacteria found in arthropods, where they induce feminization, male-killing, parthenogenesis, and cytoplasmic incompatibility (CI). CI is conditional male sterility, in which Wolbachia-infected males successfully mate with infected females,...
