Orco mediates olfactory behaviors and winged morph differentiation induced by alarm pheromone in the grain aphid, Sitobion avenae.

Insect Biochemistry and Molecular Biology, 2015
Olfaction is crucial for short distance host location and pheromone detection by insects. Complexes of olfactory receptors (ORs) are composed of odor-specific ORs and OR co-receptors (Orco).

The impact of individual ladybirds (Coccinella septempunctata, Coleoptera: Coccinellidae) on aphid colonies

European Journal of Entomology, 2000
Pea aphids (Acyrthosiphon pisum) have been reported to produce winged offspring in the presence of predatory ladybirds. These offspring may leave host plants by flight after they have developed into winged adults.

The evolutionary ecology of aphids' immunity [PDF]

Invertebrate Survival Journal, 2011
Aphids comprise 4,400 species that live in close interactions with their host-plants, the parasitoid wasps and fungi they encounter, as well as several bacteria including Buchnera aphidicola, an obligatory, nutrient-providing symbiont.
