Evolutionary Ecology 3 4 Annual Review of Entomology 37 The Hebrew University of Jerusalem. Journal aphhis Insect Physiology 16 6 The host range of the oleander aphid includes several genera of Asclepiadaceae GomphocarpusAsclepiasand Calotropis and Apocynaceae Nerium and Vinca.
Aphis nerii – Wikipedia
Thus, reduced body size does not increase the cost of being able to fly, at least under the conditions of these experiments.
It has been reported feeding on 16 other plant families, including the Asteraceae, Convolvulaceae and Euphorbiaceae – albeit sometimes as overflow hosts.
When it wishes to feed, the aphid moves the tip of the rostrum to the surface of the plant. The wasp larva pupates inside this rigid skin which is called a mummy. This substantial variation in intra- specific density dependence is associated with temperature and host-plant species. Some of these are hyperparasitoids, parasites aaphis parasites.

Ecology 89 8 Nymphs go from one stage to the next by moulting, changing their skin. This species probably originated in the Mediterranean region, the origin of its principal host plant, oleander. Behavioral Ecology and Sociobiology Yet these effects differed among milkweed genotypes, and there were one or more plant genotypes for each aphid species where coexistence was predicted.

He describes the influence on predator behaviour, and the survival of the aposematic Aphis neriiin comparison with the nerui, cryptic aphid, Acyrthosiphon pisumwhen offered to two predators with different foraging tactics. Outbreaks of Aphis nerii occurred only at urban sites where plants were regularly pruned and watered.
The oleander aphid ingests sap from the phloem of its host plant.

Aphis nerii develops primarily on plants of the family Apocyanaceae, but may occasionally infest Compositae, Convolvulaceae, and Euphorbiaceae, only rarely on citrus.
Because of their telescoping of generations, aphids can be strongly influenced by maternal ndrii. Views Read Edit View nerij. The body of a wingless adult is about 1.

Coccinellidae predator 10 adventive Apolinus lividigaster Mulsant, Yellow shouldered ladybird Beetle Coleoptera: Winged adult females are usually only seen when the host plant is no longer viable, or when a colony becomes overcrowded to the point where migration to other host plants must occur.
Several parasitoids and predators of Oleander aphids are known in New Zealand, but no fungal pathogen has been recorded. Sizes range from 1. Aphis nerii Boyer de Fonscolombe Taxonomic placing: Sequestration of cardenolides increased with diet specialization, with Myzocallis asclepiadis accumulating twice as much as any other species, perhaps explaining apis susceptibility to plant cardenolides.
