1. Scent traps and trap crops for broad bean weevil (Bruchus rufimanus) control
Master-uppsats, SLU/Dept. of EcologySammanfattning : Bönsmyg (Bruchus rufimanus) är en skadeinsekt vars larv orsakar skada i åkerböna (Vicia faba minor L), vilket reducerar bönornas kvalitet och kommersiella värde. Detta projekts syfte var att testa och utvärdera doftfällor i kombination med fångstgrödor som en biologisk kontroll mot bönsmyg. LÄS MER

3. Shedding light on alternative shrimp fishing : development of shrimp pots with a focus on selection, attraction and behaviour
Master-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : In search of a less destructive alternative to current shrimp fishing methods, both in terms of bycatch reduction and increasing shrimp-catch in pots, this study aims to analyse the catches and bycatches of different pot designs and alternative attractants for pot fishing on Northern shrimps (Pandalus bore-alis). There are three main objectives: (1. LÄS MER
4. Black coffee twig borer, Xylosandrus compactus (Eichhoff) on robusta coffee in Uganda : impact of shade level on abundance of BCTB and knowledge levels about BCTB
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : The Black Coffee Twig Borer (BCTB), (Xylosandrus compactus (Eichhoff)) is a devastating pest on robusta coffee in Uganda. The coffee in Uganda grows mostly in agroforestry systems where trees and crops are combined and interact with each other. LÄS MER
5. Olfactory response in caterpillars of Pieris rapae for host recognition
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Plants interact with phytophagus insects through release of volatile chemical compounds. They can either function as a defense against herbivores by attracting predators and parasitoids, or they can act as an attractant for the herbivores themselves. LÄS MER
