   Sammanfattning : Insects have a remarkable ability to sense whether odours are released from one point source or from two closely separated ones.

   Nyckelord :Coccinella septempunctata; attraction; odour orientation;

   Sammanfattning : The ability of the seven-spotted ladybird Coccinella septempunctata (L.) to learn to associate a combined stimulus of colour and odour with food was investigated. Four odours (menthol, 1,8-cineole, methyl salicylate and perfume) and three colours (red, yellow and green) formed twelve treatments that were combined with aphids and sweetened butter. LÄS MER
