Wolbachia Infection In Gall Associated Insect Communities In Illinois And Indiana, Jakeb Watts
Masters Theses
Wolbachia is a maternally inherited, gram-negative bacterium and has been found to be associated with up to 60% of all insects, frequently resulting in male-killing, feminization, and cytoplasmic incompatibility in the hosts. Gall wasps and other gall-forming insects induce on various host plants abnormal tissue growths, or plant galls, with distinct morphology. They are considered as obligatory parasites to their host plant. The presence of Wolbachia infection in gall wasp populations in North America has not been extensively documented. Given the strong influence on host reproduction, not knowing Wolbachia infection in insect populations prevents the understanding of how populations are …

Nuclear Fingerprinting Identification Of Black Fly Species In The Simulium Jenningsi Species Group (Diptera: Simuliidae), Gail Lynn Senatore
Masters Theses
SourceURL:file://localhost/Users/johnmoulton/Desktop/SenatoreGailMay2012.docA molecular approach was taken to differentiate morphologically homogeneous species within the Simulium jenningsi species group (SJG). This group of Nearctic black flies consisting of 22 recognized species has its highest diversity in the southeastern United States. No other group of black flies in this region is more ubiquitous or pestiferous. Female black flies in this group are nearly isomorphic, which complicates identification, elucidation of host specificity and pest status, and directed control of through application of Bti in the appropriate natal streams. Among SJG species, only S. luggeri Nicholson & Mickel, S. jenningsi Malloch, and S. penobscotense Snoddy & …
