Aphids (Hemiptera)

2014
Aphids (Hemiptera: Aphididae) are ancient insects, whose fossils go back to the Triassic, about 220-210 million years (Grimaldi and Engel 2005). To date, they are present in most of the world’s biomes, including the tropics and subarctic regions, where they infest a huge range of plants (Loxdale 2009) causing several damages due not only to their ...

The aphid-bacterial symbiosis: a comparison between pea aphids and black bean aphids

Entomologia Experimentalis et Applicata, 1996
Over the years, a variety of aphid species have been used to study the symbiosis with the bacteria Budinera (e.g. Ehrhardt, 1969; Mittler, 1971; Hinde, 1971; Campbell & Nes, 1983). Recent research, however, has focused almost exclusively on one species, the pea aphid Acyrthosiphon pisum.

Ant-Aphid Association: Role of Aphid Alarm Pheromone

Science, 1976
When 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.

An improved aphid electroantennogram

Journal of Insect Physiology, 1998
Excised 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.
