… These seedlings were then examined on 4 occasions, throughout the summer, for feeding scars caused by pine weevils. The second field experiment was conducted on a fresh clear cutting outside Forshaga in west central Sweden. Here, the trapping part of the experiment consisted of …
… only Swedish feeds. In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding with only KRAV-approved feeds. The most interesting protein crops, for example rape and rape products, field beans, peas and lupines are compared with soya bean …
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 …
… compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use. The results for fallow deer supported the hypothesis that there are fewer individuals present during the bear treatment (change in patch use). Red deer and roe …

… in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. The aim of this thesis was to study the behavior and …
bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.
… and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the …
… the JA-, ET- and SA- defenses, which result in different chemical responses. Feeding experiments with the plant A. thaliana, the generalist insect pest Spodoptera littoralis and the specialist insect pest Plutella xylostella have been conducted. The results showed that the …
… can be assumed to cause pain, which may be one reason why the fish stops feeding for several days following vaccination. Many analgesics inhibit the synthesis of prostaglandin, and thus inhibit both pain and inflammation. The local anasthetics used to immobilize fish are given …
… angled fishbone pit (2x10) and there is three cubicle rows on each side of the feeding table. The roof has a regulated ridge opening which also is a light inlet. Both the roof and the gable is isolated while the long sides consist of double transparent plastic wall which is …
… cold shortening can be prevented. Goat meat is a high quality meat. During experiments, a test panel was used to determine the taste of goat meat and it resulted that goat meat was well accepted. A diet with either goat milk or a goat milk replacer doesn’t affect the meat …
