Waldränder zeigen eine strukturelle Diversität die mit hoher Artendiversität zusammenhängt. Es wurde auch festgestellt, dass nicht jeder Waldrand dem anderem gleich ist, denn ob sonnig oder schattig-, nord- oder süd- exponiert, verändern sich die mikroklimatischen Bedingungen. Bäume werden von zahlreichen Insektenarten als Nahrung und Lebensraum genutzt, wobei unterschiedliche Expositionen eine Rolle bei der Habitatfindung spielen. Eine wichtige Insek-tengruppe sind hier die Schmetterlinge. Auf Grund der Voruntersuchung von Damm, 2003 an waldrandbesiedelden Lepidopteren wurden zwei Falterarten, das Abendpfauenauge Smerin-thus ocellatus L. und der Große Gabelschwanz Cerura vinula L. für weitere chemoökologi-sche Studien der Wahrnehmung und des Verhaltens ausgewählt. Es sollte der Mechanismus der Habitat- und Wirtspflanzenfindung erklärt werden. Für die Verbesserung der Quantifizierung der Blattmasse wurde die LbT-Methode (Länge der beblätterten Triebe) optimiert und angewendet. Die Duftproben wurden von Bäumen an un-terschiedlich exponierten Waldrändern und im Gewächshaus mit der CLSA-Methode ge-nommen und mit dem Gaschromatograph mit gekoppeltem Massenspektrometer analysiert. Weiterhin wurden elektrophysiologische Signale der Insektenantennen auf chromatographisch getrennten Duftmustern abgeleitet (EAD)

New Strategies for the Detection of Fusarium Infection and Mycotoxin Contamination of Cereals and Maize by Eva-Maria Becker( )

2 editions published in 2013 in English and held by 25 WorldCat member libraries worldwide

Phytopathogene Fusarium spp.treten weltweit in landwirtschaftlichen Kulturen auf und führen häufig zur Ertragsreduktion, Verschlechterung der Produktqualität sowie Kontaminationen der Erntegüter mit toxischen Sekundärmetaboliten, sog. Mykotoxinen. Die durch Fusarium spp. hervorgerufene partielle Taubährigkeit (FHB) des Weizens und anderer Getreidearten sowie die Fusarium Kolbenfäule an Mais sind aus ökonomischer Sicht von besonderer Bedeutung. Im Rahmen dieser Arbeit wurde die Verwendung von volatilen organischen Verbindungen (VOCs) zur Detektion von Fusariosen an Somme

Raps (Brassica napus L.) ist die bedeutendste Ölpflanze in Deutschland. Der Ertrag wird jährlich durch den Befall von Schädlingen bedroht. Zum Einsatz kommen im konventionellen Anbau verschiedene Insektizide. Der Befall mit Rapsstängelrüsslern (Ceutorhynchus napi GYLL.) kann bis zu 70 % Minderertrag zur Folge haben. Entscheidend für die Ausprägung des Schadens ist der Vorgang der Eiablage. Mit der Eiablage gibt das Weibchen ein Sekret ab, welches das Stängelmark schädigt und die charakteristischen Symptome hervorruft. Die Symptome sind Stauchung der Pflanzen, verdrehte und aufgeplatzte Stän

The study can be divided into three sections. In the first section, wood was treated with different commercially available silica sols of varying pH and surface modification. While alkaline silica sols could not be impregnated into the wood due to lowering of pH and precipitation, neutral and acidic silica sols showed good penetration. One of the tested silica sols with an acidic pH value and cationic surface modified with aluminum-oxychloride reduced water uptake and fungal decay due to incubation with the brown rot fungus Coniophora puteana (pine sapwood) and the white rot fungus Trametes

The development of wood composites such as fibreboards or particle boards rely on the intention to improve the efficiency of the wood use and to expand the application of the material wood. The conventional wood composites do have a significant role in the timber industry. In the past decades, these products have been developed to versatile products which combine different resources, especially wood, efficiently. To achieve the best properties of these products and in addition to guarantee a sustainable and eco-friendly production, raw and waste wood are combined to produce wood composites
Insect olfaction as an information filter for chemo-analytical applications by Sebastian Paczkowski( )

1 edition published in 2014 in English and held by 16 WorldCat member libraries worldwide

Die Geruchswahrnehmung von Insekten ist an die spezifischen Anforderungen der Ökosysteme angepasst, in denen sie leben. Von Insekten wahrgenommene Volatile können Informationen über den Ort eines geeigneten Ovipositionsplatzes oder den physiologischen Zustand einer Wirtspflanze geben. Da der Geruchssinn der Insekten sich seit Millionen von Jahren an die Wahrnehmung bestimmter Volatile angepasst hat, können die wahrgenommenen Volatile als Markerstoffe angesehen werden, die zuverlässig einen Ökosystemzustand angeben können. Die Identifikation dieser Markerzustände und die Evaluation ihrer Nüt
Exploring the interactions of bacterial secondary symbionts (BSS) in wheat aphids, Sitobion avenae F. with parasitoids by Sajjād ʻAlī( )

2 editions published in 2015 in English and held by 16 WorldCat member libraries worldwide

Bacterial secondary symbionts (BSS) are renowned for their capacity to protect their hosts against natural enemies. Sitobion avenae (F.) is recently reported for Hamiltonella defensa and Regiella insecticola infections. Among natural enemies, parasitoids are the most effective bio-control agents. Host feeding strategy has been adopted by many parasitoids to increase their longevity and fecundity. Parasitoid-host interactions are highly specialized and depend upon the environmental factors and the genotypic backgrounds of the species involved. Besides the innate defence system, BSS compositi
Tritrophic interactions between Populus tremula, leaf beetles and their natural enemies - from the field to the laboratory by Paul-Albin Maximilian von Fragstein und Niemsdorff( )

A drastic increase of global energy consumption is expected for the following years. Due to the increasing demand for renewable energy, much of the current research focuses on short-rotation forestry with high productive Salix and Populus species as a potential energy source. In this context the European aspen (Populus tremula) gained importance for biomass production, because of its ability to reach considerable growth rates even on poor soils and under unfavourable habitat conditions. The European aspen is a pioneer species and is one of the most widespread tree species in boreal and temperate forests. On natural sites aspen create habitats for a rich arthropod community including many endangered species. Current knowledge in plant-insect interactions of willows and poplars is based on studies, which are mostly concentrated on only two trophic levels and differences in leaf chemistry affecting phytophagous insects
The effect of root volatiles on the orientation behaviour of cockchafer larvae in the soil = Der Einfluss von Wurzelvolatilen auf das Orientierungsverhalten von unterirdisch lebenden Maikäferengerlingen by Sonja Maria Weissteiner( )

1 edition published in 2011 in English and held by 14 WorldCat member libraries worldwide

The present study investigates the effect of root volatiles on the orientation behaviour of cockchafer larvae Melolontha hippocastani in the soil. Cockchafer larvae are known as severe pests in agriculture and forestry. The present study adresses three relevant aspects of their chemical ecology linked to food choice belowground: Volatile organic compounds (VOCs) of several potential host plant roots and shoots are investigated and analysed by using gas chromatography mass spectrometry (GC-MS). The obtained volatile patterns of damaged roots differ clearly from the undamaged ones. Emitted shoot volatiles differ clearly from the emitted root volatiles. Electrophysiological methods are employed to record sensory reactions of the detached larval antennae to several of the previously identified compounds. Volatile emissions of Quercus sp. are investigated in detail. By using electroantennography (EAG), changes in the receptor potential elicited by odour stimuli are recorded. It turns out that seasonal and maybe also circadian rhythms appear to play an important role in cockchafer larvae antenna physiology. The behavioural response of cockchafer larvae is tested on selected compounds. A dual choice test setup is designed to study the behavioural orientation of the belowground living larvae. Attractive and repellent compounds in host plants are identified. Preparative methods show the antennal lobes (ALs, first central processing unit for olfactory information processing in the insect brain) of 3rd instar of M. hippocastani to contain a high number of glomeruli, which are regarded as the functional subunits of odour discrimination
How entomopathogenic endophytic fungi modulate plant-insect interactions by Sandra Milena Aragón Rodríguez( )

2 editions published between 2016 and 2017 in English and held by 14 WorldCat member libraries worldwide

Tomato plants host multiple microbes able to colonize plant tissues endophytically without causing symptoms of infections. Whether these microorganisms living inside the plants co-exist completely undetected by the plant metabolism remains to be explored in detail. This research contributes to the understanding of the multitrophic interaction among tomato plants, fungal endophytes and the insect herbivores. We focused the research on three main topics (i) whether the studied fungi are able to colonize endophytically tomato tissues, (ii) which parameters are influenced by an endophytic colon
Exploitation of synergistic effects between semiochemicals and Metarhizium brunneum against soil pests by Michael Albert Brandl( )

2 editions published in 2016 in English and held by 14 WorldCat member libraries worldwide

Root-feeding insects, such as the larvae of the western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) and wireworms Agriotes spp. Eschscholtz (Coleoptera: Elateridae), the larvae of click beetles, are widely recognized as major soil pests, which influence agricultural productivity. Environmental concerns and a high risk of insecticide use as well as the lack of other efficient control options require new and effective strategies to target these pests. Two behavioral based control approaches, combining the use of the entomopathogenic fungus Metarhizi
Surveillance of tick-parasitized voles, mice and roe deer in Germany: Arboviral infection rates in relation to population densities and host characteristics by Christian Kiffner( )

1 edition published in 2010 in English and held by 13 WorldCat member libraries worldwide

This dissertation is focussed on the ecology of tick-borne encephalitis (TBE), an infectious disease of major medical significance. The thesis is organised as a series of 9 self-contained chapters, enframed by a general introduction to the topic and the research questions (Chapter 1) and a concluding general discussion (Chapter 11). Chapter 2 preludes the chapters 3-9. Using human incidence data from 140 counties in southern Germany over a period of 8 years, several abiotic and biotic factors contributing to the infection risk of TBE were identified in a spatial explicit, predictive framework. By controlling for unexplained spatial and temporal variation, the analysis indicated that type and amount of forest cover, and indexed population densities of roe deer (Capreolus capreolus) in the previous year were positively associated with TBE incidence in humans. An index of forest fragmentation and red deer (Cervus elaphus) and red fox (Vulpes vulpes) population densities in the previous year were negatively associated with TBE incidence in humans. Unexpectedly, spring warming, a suspected key driver for seasonal synchrony of immature ticks and thus for TBE transmission dynamics, was negatively associated with TBE incidence. The results are discussed with respect to their biological significance and the current resolution (county level) of the public health system is critically discussed. Building up from this analysis, the following chapters investigate specific issues on a finer scale using field data. Chapter 3 provides a brief overview of the study area in southern Hesse
Lethal and sublethal effects of insecticides on mortality, migration and host searching behaviour of tersilochine parasitoids on winter oilseed rape = Letale und subletale Effekte von Insektizidbehandlungen auf Mortalität, Migration und Wirtssuchverhalten der Parasitoide von Rapsschädlingen by Nadine Neumann( )

1 edition published in 2011 in English and held by 11 WorldCat member libraries worldwide

Oilseed rape crops are attacked by various economically important insect pests that require frequent treatments of broad spectrum insecticides. The extensive usage of insecticides might have strong negative impact on natural enemies. All pest species on oilseed rape are parasitized by specialist larval endoparasitoids which are mainly active in the late bud stage up to the end of flowering. The aim of this thesis was to identify possible strategies to protect hymenopteran parasitoids, by the choice of insecticide (contact pyrethroids vs. systemic neonicotinoid), applied dose rates (50% vs. 100% of recommended field dose rate) and time of application (beginning vs. end of flowering). In laboratory experiments the toxicity of insecticides to parasitoids and the role of volatiles emitted from uninfested and infested oilseed rape plants, as well as the volatile blend emitted from insecticide-treated and untreated plants were analysed in behavioural and electrophysiological (EAG-GC/MS) bioassays, using female Tersilochus obscurator
Developing and testing plant health management options against the maize cob borer Mussidia nigrivenella Ragonot (Lepidoptera: Pyralidae) in West Africa by Komi Agboka( )

1 edition published in 2010 in English and held by 11 WorldCat member libraries worldwide

The present research project aimed at developing and testing different IPM components focusing on i) habitat management particularly maize-legume intercropping and trap crops, ii) botanical formulations with special emphasis on neem and Jatropha curcas and iii) biological control using redistribution or new association approach for sustainably controlling the maize cob borer Mussidia nigrivenella Ragonot (Lepidoptera: Pyralidae) in field and in storage systems. To this end, field and lab experiments were conducted mainly in different locations in Benin. Field experiments conducted in four different locations in Benin using four by two pattern of maize-legumes or cassava planting indicated that intercrops could reduce the number of eggs and larvae of M. nigrivenella compared to the monocrop. Maize- Canavalia ensiformis and maize-Tephrosia vogelii proved to be the most effective combinations for reducing M. nigrivenella populations in the different locations
