Odour communication in two brassica feeding aphid species (Homoptera: Aphidinea: Aphididae)


, : Odour communication in two brassica feeding aphid species (Homoptera: Aphidinea: Aphididae). Entomologia Generalis, 164: 241-247

Olfactometer screening was carried out in the laboratory on odour factors in the inter- and intra-specific communication of Brevicoryne brassicae and Lipaphis erysimi. Alatae of both species reacted positively to food plant (rape) odour. An aggregation pheromone was emitted by alatae of both species. Apterae did not respond to this. Alatae of both species reacted negatively to the odour of alatae of the other species.
