The response of alate Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae) to volatile substances from four non-host plant extracts under laboratory conditions

Abstract

Volatile compounds present in essential plant oils are known to influence insect behaviour. They are generally of low molecular weight, highly volatile, have a unique mode of action and are sometimes of low toxicity to non-target organisms. One example of a volatile compound extracted from a plant is methyl salicylate which is being used to reduce aphid infestation on barley in some European countries.
