<title>Biological and molecular characterization of caecum-associated symbionts in the Pentatomidae</title>
<link>http://hdl.handle.net/10125/20599</link>
<description>Thesis (Ph.D.)--University of Hawaii at Manoa, 2008.; The Pentatomidae is one of the largest families within the suborder Heteroptera (order Hemiptera), with over 4000 described species within eight subfamilies. Stink bugs are major pests of economically important crops worldwide including soybeans, rice, pecan, cocoa and macadamia nuts. Relationships between microorganisms and insects have been previously studied, but the majority of these associations remain poorly understood. In this dissertation I present molecular data showing that Nezara viridula, Acrosternum hilare Murgantia histrionica, Euschistus heros, Chlorochroa ligata, C. sayi, C. uhleri, Plautia stali and  Thyanta pallidovirens harbor a common dominant caecum-associated bacterial symbiont in their midgut. I also show that oral rather than transovarial transmission occurs by detecting the symbiont on eggshells after nymphs had hatched, instead of detecting symbionts in female ovarioles. Additionally, I demonstrated that these symbionts are polyphyletic suggesting that replacement of the symbiont may occur over time. Phylogenetic placement showed the pentatomid symbionts were associated with the plant pathogens Erwinia and Pantoea. Using a demographic approach I analyzed the effect of egg masses surface sterilization and temperature on the symbiont maintenance and on insect development of the pentatomids N. viridula, A. hilare and M. histrionica. Here I demonstrate that maintenance of the symbiont was affected by high temperature and egg mass surface sterilization for the species N. viridula, A. hilare  and M. histrionica. N. viridula's reproduction parameters were not significantly different between the surface sterilized and control treatments at three temperatures, however no reproduction was observed at 20&amp;deg;C of the surface sterilized treatment. Survivorship and reproductive parameters for A. hilare were negatively affected by surface sterilization of egg masses and for higher temperatures. Conversely, no effect was observed for M. histrionica. Curiously,  M. histrionica had lower rates of positive insects for the symbiont at 25&amp;deg;C than A. hilare. Here I suggest that the degree of mutualism of this association for pentatomid species is variable, given the fact that A. hilare requires its symbiont for adequate development, while M. histrionica's symbiont may not be significant in development of the host insect and N. viridula is not affected by deprivation of its gut-associated symbiont.; Includes bibliographical references (leaves 133-136).; Also available by subscription via World Wide Web; 146 leaves, bound 29 cm

<title>Non-target impacts of introduced parasitoids and validation of probabilistic risk assessment for biological control introductions</title>
<link>http://hdl.handle.net/10125/20598</link>
<description>Thesis (Ph.D.)--University of Hawaii at Manoa, 2008.; By comparing the use of single point estimates versus probability distributions in quantitative risk assessment modelling, it was demonstrated that the use of point estimates can hide important variability and significantly impact the estimates of risk. It was also demonstrated that, at least in this study system, the use of apparent mortality significantly increased the estimate of risk compared to the use of marginal attack rate.; Field surveys and partial life table studies were conducted to assess apparent mortality and marginal attack rate, respectively. Field surveys of larvae were conducted at eight different sites throughout the Hawaiian Islands, parasitism rates by individual parasitoid species varied significantly among study sites of varying ecological conditions. Adventive parasitoids rather than purposely introduced ones were responsible for the majority of  U. stellata apparent mortality. Results from the life table studies showed that predation) was the major larval mortality factor at all study sites and that parasitism contributed minimally to total mortality. The two purposely introduced parasitoids were present at high altitude, in relatively undisturbed sites.; Multivariate analyses were used to detect patterns in species assemblage among sites. Udea stellata density, elevation, and level of habitat disturbance significantly explained variability in the parasitoid assemblage among sites. Most species increased in abundance with higher densities of U. stellata and some were restricted to less disturbed sites.; This dissertation addressed non-target parasitism of the endemic Hawaiian moth Udea stellata (Butler) and validated a probabilistic risk assessment approach for biological control introductions.  Udea stellata is distributed across a wide gradient of environmental conditions, which allowed an assessment of non-target effects under a range of ecological conditions. Seven parasitoid species were associated with  U. stellata larvae. Trathala flavoorbitalis, Casinaria infesta  and Triclistus nr. aitkeni are of adventive origin; Cotesia marginiventris and  Meteorus laphygmae were purposely introduced to Hawaii; and  Diadegma blackburni and Pristomerus hawaiiensis are of unknown origin.; Includes bibliographical references (leaves 186-208).; Also available by subscription via World Wide Web; 208 leaves, bound 29 cm
