Toxoptera aurantii, also known as both the black citrus aphid and brown citrus aphid, is a species of aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is known to hosts in well over 150+ plant species. [1]
Toxoptera citricida (syn. Toxoptera citricidus) is a species of aphid known by the common names brown citrus aphid, black citrus aphid, and oriental citrus aphid. It is a pest of citrus and vector for the pathogenic plant virus citrus tristeza virus. The aphid spread the virus through citrus groves in Brazil and Venezuela in the 1970s, leading ...
It is a pest of citrus crops, and is commonly known as the citrus blackfly because of its slate-blue colour. It originated in Asia, but has spread to other parts of the world. [ 1 ] The parasitic wasps, Encarsia perplexa and Amitus hesperidum can help control the pest.

Diaphorina citri, the Asian citrus psyllid, is a sap-sucking, hemipteran bug now in the taxonomic family Liviidae. [1] It is one of two confirmed vectors of citrus greening disease . [ 2 ] [ 3 ] It has a wide distribution in southern Asia and has spread to other citrus growing regions.
Thus, aphids show very complex and rapidly changing within-year dynamics, with each clone going through several generations during the vegetative season and being made up of many individuals, which can be widely scattered in space. The survival of the eggs and/or overwintering aphids determines the numbers of aphids present the following spring ...
Aphis spiraecola is a species of aphid described in 1914 by Edith Marion Patch. [1] Its common names include green citrus aphid, [2] Spirea aphid, [3] and apple aphid. [4] It is distributed worldwide, and is most abundant in the United States. [5] It has a diploid chromosome number of 2n=8. [6]
The brown citrus aphid is considerably more efficient at transmitting the virus than are other aphids that infest citrus. In Florida, it has been shown to be from six to twenty five times as efficient as Aphis gossypii , the most efficient vector found in the state before the introduction of the brown citrus aphid prior to 1995.
