1. Biology of the diamondback moth (Plutella xylostella) and its future impact in Swedish oilseed rape production : a literature reviewKandidat-uppsats, SLU/Dept. of Ecology
Sammanfattning : 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
- Kandidat-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)
Sammanfattning : 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. LÄS MER
- Kandidat-uppsats, SLU/Dept. of Ecology
Sammanfattning : The plant family of Brassicaceae is widespread around the world and many members of the family are important food and oil-seed crops. There are many insect pests specialized on brassicaceous crops and interactions between crop and pest are well studied. LÄS MER
4. Field margins vs. insecticides : factors affecting the density of predators attacking Plutella xylostellaL3-uppsats, SLU/Dept. of Ecology
Sammanfattning : 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
5. Predators of Plutella xylostella in Nicaragua : feeding capacity and potential role in biological controlL3-uppsats, SLU/Dept. of Ecology
Sammanfattning : 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
