Cockroaches (Blattodea) Of Southern Louisiana: Morphology, Diversity, And Life Histories, Forest Brady Huval
LSU Master's Theses
The state of Louisiana has both temperate and subtropical climates and includes six ecoregions. Two ecoregions in south-central Louisiana were surveyed for members of the order Blattodea to better describe the diversity, life histories, and taxonomy of adult and nymphal cockroaches. Blattodea, excluding the newly included epifamily Termitoidae, is an understudied order of insects in spite of the importance species that are infamous peridomestic pest. The order Blattodea currently contains 9 families comprising of 460 genera. There are approximately 7570 described species 4641 of which are cockroaches and 2929 are termites. Complete information on life histories lacks for the majority …

A Revision And Phylogenetic Analysis Of The Genus Eutyphlus Leconte (Coleoptera: Staphylinidae: Pselaphinae) With A Comparison Of Sampling Methodologies, Brittany Elin Owens
LSU Master's Theses
My thesis research includes three components: (1) a methodology project, (2) a systematic project comprising a taxonomic revision, and (3) a morphology-based, cladistic analysis. 1. The methodological study compared the Winkler (Moczarski) eclector and the Berlese-Tullgren funnel (referred to hereafter as “Winkler” and “Berlese” funnels, respectively) as methods for extracting forest litter-dwelling Coleoptera from sifted substrate, with a focus on relevance for taxonomic studies. A general review of the history and methodologies of leaf litter arthropod extraction was provided, in conjunction with repeated, timed trials to compare the relative effectiveness of the two methods using litter samples from various geographic …
