Peterson and published by . This book was released on 2019 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American and European ash trees are highly susceptible to emerald ash borer (EAB, Agrilus planipennis). This buprestid kills hosts via larva feeding on vascular tissue which eventually kills the host plant. Two new hosts have recently been found to support larval development of EAB. White fringetrees (Chionathus virginicus) were found attacked by EAB in 2014 and since then have been found to be attacked throughout other parts of the United States, while olive (Olea europaea) has only experimentally been found to support larvae to adulthood. Chemical profiles of these two plants were collected and analyzed to determine how their volatile emissions vary among susceptible and resistant ash trees. Additionally, larvae and adult beetles were tested for their performance on these novel plants. For white fringetree, wild populations were monitored to determine the impact of EAB during the attack wave. These studies find that white fringetree foliage supports adults, but when phloem is healthy it causes high larval morality in contrast to girdled or previously attacked by EAB where larvae survived by the end of assays. In the field, EAB began to use white fringetree quickly, within a couple of years after initial exposure. Female choice suggests white fringetree and susceptible ash are similarly preferred likely due to the similar volatile emissions. These chemicals likely caused host range expansion of EAB to this novel host. In contrast to ash, the impact of EAB on white fringetree is minimal. This plant mostly loses a branch or two from larval girdling, which in ornamentally planted fringetrees can be aesthetically displeasing. On olive, EAB is likely to be even less damaging because larvae take longer to develop than in ash and larvae die quickly in young, photosynthesizing stems. Adults did not perform well because oleuropein may cause them to compensatory feed and causing malnutrition. In North American forests, if EAB continues to destroy ash species at such high rates, EAB may be driven to use white fringetree more often. With continued use of this host, EAB is likely to adapt to better utilize white fringetree which could eventually lead to host switching.

Download or read book Effects of Temperature and Photoperiod on Host parasitoid Synchrony and Evaluation of Sampling Methods for Oobius Agrili an Introduced Egg Parasitoid of Emerald Ash Borer written by Toby R. Petrice and published by . This book was released on 2020 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerald ash borer (EAB), Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae) is one of the most destructive forest insect pests to be introduced into North America. Oobius agrili Zhang and Huang (Hymenoptera: Encyrtidae) is an EAB egg parasitoid native to northeastern China. EAB has spread to most of eastern North America and O. agrili has been released throughout most of this distribution. Both species now occur well beyond their endemic climatic ranges. Furthermore, photoperiod modulates O. agrili diapause. Therefore, host-parasitoid synchrony could be affected in novel climatic distributions. Studies were conducted to determine the O. agrili life stages that respond to photoperiod and the critical day length for diapause induction. Results demonstrated that photoperiod induced diapause is modulated in the developing larvae and critical day length for diapause induction is between 14.25 and 14.5 hours of day light. Next. a temperature driven multiple cohort rate summation model was developed to simulate the phenology of O. agrili and EAB. Critical day length was integrated into the model to predict interactions of photoperiod and temperature regimes on host-parasitoid synchrony. The model was validated with O agrili and EAB trapping from Michigan sites. Model predictions compared with trapping data demonstrated that O. agrili has primarily two generations per year in south central and northwestern Michigan, and O. agrili enters diapause before critical day length occurs in south central Michigan. According to simulations, spatiotemporal variation in temperature regimes does not affect O. agrili-EAB synchrony, with the exception of some northern locations. However, the effect of spatial variation in day length is still unclear and dependent on how O. agrili measures day length in the field. Finally, sampling methods, sample size and seasonal timing for detecting and monitoring O. agrili in the field were evaluated. Yellow pan traps and bark sifting for parasitized eggs were more effective at recovering O. agrili compared to sentinel EAB eggs in screened pouches and bark rearing for adults. A minimum of ten yellow pan trap or bark sifting samples should be taken from each site. Yellow pan trap sampling should be conducted between 400-1200 DD10. Results of this project provide insight and tools for evaluating O. agrili phenology and spatiotemporal synchrony with EAB oviposition, determining optimal release times, and detecting and monitoring its efficacy across its current and potential distribution in North America.

This book was released on 2001-04-26 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will provide a complete overview of an alpine ecosystem, based on the long-term research conducted at the Niwot Ridge LTER. There is, at present, no general book on alpine ecology. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions, because it offers large environmental change over relatively short distances. Factors such as macroclimate, microclimate, soil conditions, biota, and various biological factors change on differing scales, allowing insight into the relative contributions of the different factors on ecological outcomes.

This book was released on 1997-02-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the ecological effect a species can have when it moves into an environment that it has not previously occupied (commonly referred to as an 'Invasion'). It is unique in presenting a clear and accessible introduction to a highly complex area - the modelling of biological invasions. The book presents the latest theories and models developed from studies into this crucial area. It includes data and examples from biological case studies showing how the models can be applied to the study of invasions, whether dealing with AIDS, the European rabbit, or prickly pear cactuses. - ;In nature, all organisms migrate or disperse to some extent, either by walking, swimming, flying, or being transported by wind or water. When a species succeeds in colonising an area that it has not previously inhabited, this is referred to as an `invasion'. Humans can precipitate biological invasions often spreading disease or pests by their travels around the world. Using the large amount of data that has been collected from studies worldwide, ranging from pest control to epidemiology, it has been possible to construct mathematical models that can predict which species will become an invader, what kind of habitat is susceptible to invasion by a particular species, and how fast an invasion will spread if it occurs. This book presents a clear and accessible introduction to this highly complex area. Included are data and examples from biological case studies showing how these models can be applied to the study of invasions, whether dealing with AIDS, the European rabbit, or prickly pear cactuses. -

Download or read book Integrating Biological Control into Conservation Practice written by Roy van Driesche and published by John Wiley & Sons. This book was released on 2016-05-17 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species have a critical and growing effect upon natural areas. They can modify, degrade, or destroy wildland ecosystem structure and function, and reduce native biodiversity. Landscape-level solutions are needed to address these problems. Conservation biologists seek to limit such damage and restore ecosystems using a variety of approaches. One such approach is biological control: the deliberate importation and establishment of specialized natural enemies, which can address invasive species problems and which should be considered as a possible component of restoration. Biological control can be an effective tool against many invasive insects and plants but it has rarely been successfully employed against other groups. Safety is of paramount concern and requires that the natural enemies used be specialized and that targeted pests be drivers of ecological degradation. While modern approaches allow species to be selected with a high level of security, some risks do remain. However, as in all species introductions, these should be viewed in the context of the risk of failing to reduce the impact of the invasive species. This unique book identifies the balance among these factors to show how biological control can be integrated into ecosystem restoration as practiced by conservation biologists. Jointly developed by conservation biologists and biological control scientists, it contains chapters on matching tools to management goals; tools in action; measuring and evaluating ecological outcomes of biological control introductions; managing conflict over biological control; and includes case studies as well as an ethical framework for integrating biological control and conservation practice. Integrating Biological Control into Conservation Practice is suitable for graduate courses in invasive species management and biological control, as well as for research scientists in government and non-profit conservation organizations.
