Ant-Aphid Association: Role of Aphid Alarm Pheromone
Science, 1976When attacked by predators, aphids secrete alarm pheromones that cause nearby aphids to disperse. Ant-associated (myrmecophilous) aphid species disperse less readily than nonmyrmecophilous species. Ant exposure further depresses the dispersive alarm behavior of myrmecophilous species.

Occurrence of hop aphid phagostimulants in the honeydew of aphids
Entomologia Experimentalis et Applicata, 1992AbstractSeveral aphid honeydews were incorporated into sucrose solutions and presented to hop aphids, Phorodon humuli (Schrank), as artificial diets in free‐choice bioassays. Small additions of honeydew collected from two species of aphid feeding on hop, Humulus lupulus L., arrested the searching behavior of the hop aphid and appeared to stimulate ...

Aphids in jeopardy? Aphid communities on xerothermic habitats
Biologia, 2015The aim of this project was to characterize the aphid groups closely, relating to xerothermic plant assemblages (Festuco-Brometea class) and identifing the aphid species diagnostic for this type of community (aphidocoenosis). The paper represents the first attempt to classify the aphid communities distributed in one type of particular habitat at a ...

Research into biological control of aphids continues. However, because of the high growth rates of aphid populations, it is unlikely that they can be fully controlled in all cases. Correct cultural practices (e.g. avoiding nitrogen overfertilization) may reduce the rate of increase of aphid populations and enhance the effectiveness of biological ...

ABSTRACTWithin the Aphidoidea, most species of Aphididae, as long as they are in small numbers and not carrying plant viruses, do little perceptible damage to their food plants. In species that cause toxicoses, it is usually assumed that some component of the saliva must be responsible.

Outlook on Agriculture, 1961 Aphids of bewildering diversity cause severe losses in a wide range of crops, partly through mechanical damage but mainly through virus transmission. Fortunately, many aphicides presenting a choice of suitable properties are now available and can be applied to the aerial parts of the crop, to the seed before planting or directly to the soil.

An improved aphid electroantennogram
Journal of Insect Physiology, 1998Excised antennae have been used to record aphid electroantennograms (EAGs) but these preparations have small, rapidly declining responses and a short usable life. An improved EAG technique is described and evaluated using alate virginoparae of the black bean aphid, Aphis fabae, and a series of plant volatiles.

Publisher Summary This chapter discusses insect aphids and their agricultural importance. Aphid damage is among the most serious of agricultural and horticultural problems. Aphids, as the superfamily Aphidoidea, belong to the Hemipteran Sternorrhyncha with Aleyrodoidea, Psylloidea, and Coccoidea.
