Aphid Alarm Pheromone as a Cue for Ants to Locate Aphid Partners
PLoS ONE, 2012 The mutualistic relationships that occur between myrmecophilous aphids and ants are based on the rich food supply that honeydew represents for ants and on the protection they provide against aphid natural enemies. While aphid predators and parasitoids actively forage for oviposition sites by using aphid semiochemicals, scouts of aphid-tending ant ...

Cannibalism and Predation by Aphids [PDF]
Nature, 1968 APHIDS are usually regarded as feeding exclusively on plant sap which they ingest through stylet-like mouth parts, but they have occasionally been seen to feed on animal food. During feeding on a turgid plant, they do not have to suck but depend chiefly on the pressure of the sap for ingestion.

Was Dan Janzen (1977) right about aphid clones being a "super-organism", i.e. a single "evolutionary individual"? : new insights from the use of molecular marker systems [PDF]
, 2008 Dan Janzen proposed in a paper in 1977 (loc. cit.), that a clone of aphids and for that matter dandelions consists, respectively, of one large ‘super-organism’.

New structure in cell puncture activities by aphid stylets: a dual-mode EPG study
, 2010 Intracellular punctures by aphid stylets appear as potential drop (pd) waveforms in DC electrical penetration graph (EPG) recordings. We used a dual-EPG device that recorded in one channel the ‘full EPG’ with R-plus emf-components (i.e., the usual DC EPG)
