1. The role of agroforestry tree species in biocontrol of the cabbage pest Plutella xylostella : a field study in Kenya
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Pest control in agriculture is a necessity and the use of chemicals is the method by choice for most farmers. But the use of chemicals comes with a price; the pests develops resistance and the chemicals pollutes the environment. It is therefore of urgent importance to shift pest control from chemicals to other methods. LÄS MER
2. Biology of the diamondback moth (Plutella xylostella) and its future impact in Swedish oilseed rape production : a literature review
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : The biology of the Diamondback moth, Plutella xylostella, and its impact on oilseed rape production is reviewed. The Diamondback moth, DBM, is a serious, migratory, pest and a problem worldwide because its larval stage has a ravenous appetite, which causes major economic losses in Brassica crops. LÄS MER
3. Field margins vs. insecticides : factors affecting the density of predators attacking Plutella xylostella
L3-uppsats, SLU/Dept. of EcologySammanfattning : Biological control provides a tool to reach goals such as maintaining sustainable agroecosystems and decreasing the use of pesticides. Studies show that generalist predators can reduce prey populations effectively and, thus, may function as good biocontrol agents. LÄS MER
4. Predators of Plutella xylostella in Nicaragua : feeding capacity and potential role in biological control
L3-uppsats, SLU/Dept. of EcologySammanfattning : The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the most destructive insect pests of Brassica crops in both temperate and tropical regions over the world. The insect is considered as a key pest of crucifers in Central America. LÄS MER
