Biological pest management is defined as control of pests using their natural enemies. This method has been used in Sweden since the 1970´s and it has been developed ever since. Biological pest management is today relatively common among commercial growers but there are good possibilities to apply this method in the home gardens as well. The aim with this thesis is to compile a report from both the companies that are marketing the products and the home gardener´s point of view. This should give a better understanding of the market and how it could be improved. We will give examples of products that represent the different kinds of organisms that are being used in biological pest management. Our hope is that this will be an introduction to all interested in biological pest management. The legislations regarding registration of organisms are still a matter of discussion and are causing problems to producers, distributors and the market in general. Why isn´t biological pest management more common in the home garden? The main reason appears to be the lack of knowledge in the subject. What are the benefits using biological pest management when it requires so much knowledge and it´s more expensive than conventional pest management? With the environmental problems we face today, we hope that every single gardener has an interest in developing an environment as clean as possible, even if only in one's own backyard..

Det huvudsakliga syftet med min uppsats var att studera hur tre olika aspekter påverkade Gårdby socken och dess båtsmän under Stora nordiska kriget, nämligen krig, pest och missväxt. Med hjälp av de källor jag har studerat, militära rullor, kyrkoböcker och mantalslängder, har jag fått fram hur livet kunde te sig för de indelta båtsmännen men också hur pestens verkningar påverkade socknen mer långsiktigt än vad krigets utskrivningar gjorde. Jag har även studerat hur missväxten föll ut i Gårdby och jämfört detta med till exempel byn Andersvattnet, Stockholm och övriga riket..

Gerbera jamesonii is a plant with a large amount of pollen and various flower colours and a favourite host plant for Frankliniella occidentalis. The best growing temperature for gerbera is approximately 20°C. Frankliniella occidentalis or the Western Flower Thrips is a small insect that has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis.

This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.

The aim of this Master?s thesis is to examine the environmental scanning by the employees and politicians at the central administration at the County Council of Kalmar län. The background of the study is the closing of the administration library in January 2003, which gave more tasks to the hospital libraries of the County Council.The main questions of this study concerns the information needs of the employees and politicians, what electronic sources they prefer to use to satisfy those needs and if they are experiencing a need for more support and help, from a librarian or by the development of a common catalogue of hyperlinks. All 104 persons in the population were asked to answer a questionnaire on the Intranet. The task was performed by 60 persons.

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Titel Reklam i mobilen? En studie av förutsättningar för tidningsföretag att använda mobiltelefonen som marknadsföringskanal Författare Beata Jungselius Kurs MK1500 - Examensarbete i Medie- och kommunikationsvetenskap Termin VT-09 Uppdragsgivare Dagspresskollegiet Handledare Oscar Westlund Syfte Att studera förutsättningarna för tidningsföretag att använda mobiltelefonen som marknadsföringskanal. Metod Omvärldsanalys med hjälp av analysmodellen PEST samt intervjuer Huvudresultat Mobiltelefonen som marknadsföringskanal har visat sig vara väl lämpad för olika former av marknadsföringsåtgärder för tidningsföretag. Särskilt väl kan den antas fungera för tidningsföretag som utlåter annonsutrymme i form av så kallade reklambanners på sin mobilanpassade webbsida då dessa i regel ger ett högt observationsvärde såväl som en hög klickfrekvens. SMS-utskick kan även de fungera väl, förutsatt att mottagaren gett företaget tillåtelse att kontakta dem på detta vis helst på eget initiativ.

Namn: Film i undervisning ? pest eller fest? Ett elevperspektiv.Författare: Katsaras, M och Larsson, T (2007)Examensarbete på lärarprogrammet pedagogik B, 10pSyftet med arbetet är att undersöka och beskriva hur två grupper med gymnasielever uppfattar att film används och har använts i undervisning under sin skoltid. För att få svaren på frågorna skapades två stycken fokusgrupper där varje grupp bestod av fyra till fem elever i årskurs två och tre på gymnasiet. Fokusgrupper kan liknas vid ett gruppsamtal. En grupp kom från ett medieprogram och den andra från ett samhällsvetenskapligt program.

In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been examined for its potential to use as a biological control agent in cucumber production. A. limonicus can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci. Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the southern part of Sweden. The basic control agent used against thrips was the predatory mite Amblyseius swirskii. In selected areas, additional A.

The aim of this thesis is to create an understanding of the incentives for forest companies to invest in reducing carbon dioxide emissions from deforestation and forest degradation, which is termed REDD. The Brazilian Amazonas was chosen as the base for the investment case. Brazil has the largest area of rainforest in the world, and also the biggest problem with deforestation. The Amazon region of Brazil comprises rainforest which is largely intact and unexploited. Accordingly, there is significant potential scope for prospective investments in a REDD-project, and so have a noteworthy impact in preventing deforestation.The research approach used the United Nation?s Clean Development Mechanism concept was used as a framework for ascertaining the investment costs in potential REDD-projects.

Johannitermunkarna i Eskilstunaklostret var kända för att utföra sjukvårdsgärningar och väl förtrogna med för tiden rådande medicinska kunskaper. Men pesten var något helt nytt för dem och var allomfattande under åren kring 1350-talet och slog hårt inte bara i Sverige utan i stora delar av Europa.Med tanke på Rekarne­bygdens bördiga landskap som gynnade en stor lokal befolkning som bevisligen hade en stor kontaktyta utanför den egna bygden, så är möjligheterna stora att pesten nådde även Rekarnebygden..

From 1710 to 1713 the plague raged through the Swedish province of Scania. Other studies have been made on how the disease affected the society during the epidemic. This study tries to focus on the recovery afterwards. How did the population and the farmsteads recover after the plague? Statistics from parish registers and cameral records show interesting patterns in the demography, and that the recovery was far from complete 1720.

År 1993 var Fredrik Reinfeldt 28 år, ordförande för Moderata Ungdomsförbundet ochriksdagsledamot sedan det föregående valet 1991. Detta år gav Reinfeldt också ut sin bok Det sovande folket vari han jämför välfärdsstaten med ?pest smittkoppor och Aids? (Reinfeldt, 1993:12). År 2005 finner vi istället en 40-årig Fredrik Reinfeldt som sedan två år tillbaka innehar partiledarpositionen för Moderaterna och vad som är intressantare är att han förklararsig att vara välfärdsstatens främsta försvarare då han deklarerar att ?en skattefinansierad välfärd har stora fördelar? (Reinfeldt, 2005).Med anledning av ovanstående är det intressant att diskutera huruvida Reinfeldts politiska idéer har förändrats eller om de fortfarande är bestående.

The bean bruchid, Acanthoscelides obtectus is a major threat to bean production. In Ethiopia, where this study was performed, the damage by bruchids on stored beans has been reported to reach up to 38%. To use the isolates Beauveria bassiana and Metarhizium anisopliae in the management of A. obtectus can be an environmentally safe alternative for controlling the pest. In the present work the aim was to examine if the four chosen fungal isolates, B.
