Sugarcane aphid, Melanaphis sacchari Zehtner (Hemiptera: Aphididae), outbreaks on grain sorghum were first detected in the United States in 2013. The spread of sugarcane aphid across the sorghum-producing regions of North America necessitated increased ...

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, 1996Over 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, 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.

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.

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 ...
