Differences in host plant preferences and olfactory physiology between populations of the moth Spodoptera littoralis established in Egypt and Benin

This study was made to compare and distinguish any differences in olfactory recognition and host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The populations used were established in Egypt and Benin, Africa. The documentation consisted of information about (1) each of the strains development through the larval stage up to pupation on diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton, clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any possible responses to plant volatiles. Throughout the diet experiments the larvae from the Benin strain showed significantly a better development between artificial, clover, cowpea and cotton respectively, while the Egypt strain had significance between artificial, cotton and cowpea/clover as diet. Also noted was how the strains substantial development of weight differentiated if fed the cotton diet, followed by the cowpea diet showing that the Benin strain would develop a higher body mass on a cotton diet as well as on a cowpea diet. This trend was however switched once the pupal stage was reached, where the Egyptian strain contained a significantly greater body mass than the Benin strain on the artificial and the Benin strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly better on cowpea while the Egypt strain develops better on an artificial diet. During the oviposition experiment that both stains showed a clear difference in hierarchy of host plants considered suitable for oviposition, where the Egyptian strain is significantly more attracted to clover than the Benin strain. Also showed with electroantennographic recordings and significant values was the higher sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate, Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

Hur påverkar energi- och proteinrik kost intaget av energi och makronutrienter?

Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.

Something fishy in Christians : Dietrekonstruktioner genom analys av stabila isotoper på tidigmedeltida skelett från Rambodal, Styrstad Sn, Östergötland

Dietary patterns has varied throughout history, both due to resource and cultural limitations. In this thesis, a study was conducted to establish the dietary patterns of eight individuals from an early Midieaval gravesite in Rambodal, Östergötland, in order to explain why they were buried there. This was done through stable isotope analysis on collagen extracted from bone and tooth on the buried individuals. The analysis showed that these indviduals had a diet that was mainly based on freshwater fish. This suggests that these people may have been christians, due to the fact that fish was not regarded as meat and therefore you did not have to abstain from it during periods of fasting.

Gruppsammansättning och lärande : Hur elever ser på sitt lärande i grupparbeten

The aim with the study has been to get an overview of how students perceive their learning in group projects. The survey has been implemented with a quantitative questionnaire with qualitative elements during guidance. Students in grade 9 in a secondary school answered a survey study where they should take side to several proposals about learning and group work. The result shows that students in general do not find learning in group as the best learning method, but instead prefer individual learning methods when to learn new things. On the contrary, students claim that they learn best when group members not think as they but think in another direction.

Vätskebalansen hos arbetande hästar på olika dieter

Kunskapen om hur tränande hästar påverkas av olika dieter behöver bli större. Därför utfodrades 6 tränande travhästar med 3 olika typer av foderstater. Våra frågeställningar var:Hur påverkas hästens vattenintag och vätskebalans av olika foderstater? Hur vätskebalansen påverkas under arbete.Hypotesen var att hästens vattenintag och vätskebalans skulle påverkas och att vätskebalansen kommer att påverkas av de olika dieterna under arbete.Hästen får i sig vatten från tre källor, dricksvatten, vatten i foder och metaboliskt vatten. För att behålla vätskebalansen måste intaget av vatten täcka det hästen förlorar.
