SYSTEMATIC TREATMENT OF APHID GENERA
In this section we provide information on all the aphids feeding on trees, shrubs and herbaceous plants that were included in the Host Lists and Keys section of the website, treating them in alphabetical order of genera, and of species within genera. All species of which the host plant is known are included, even those appearing in square brackets in the lists because we had inadequate information to include them in the keys. If a species listed in Host Lists and Keys is not found in the alphabetical sequence then it is probably mentioned in the discussion of some other species. The index to aphid species names will show where to look.
Here are links to aphid genera beginning with each letter of the alphabet:
As in Blackman & Eastop (2000), and on the web at http://aphid.speciesfile.org, the classification of Aphidoidea follows that of Remaudière & Remaudière (1997), as this is likely to be the most widely consulted list for many years to come, with the revisions of family names proposed by Nieto Nafrìa et al. (1997). An alternative classification incorporating fossil aphids was proposed by Heie & Wegierek (2009), and is the system currently followed on the Tree of Life website. Table 3 compares these two classifications and shows the equivalent categories of the extant groups. The main difference between the two is in the level assigned to categories, so that in most cases a simple difference of word ending is involved (following the conventions “-idae” for family, “-inae” for subfamily, “–ini” for tribe and “–ina” for subtribe). However, it is important to note that Drepanosiphidae in the Heie & Wegierek system is not equivalent to Drepanosiphinae as used here, and that there are also other differences within the classification of the “drepanosiphine aphids”. Molecular work on these groups is needed to clarify their relationships.
In the course of compiling the 2006 book Aphids on Herbaceous Plants and Shrubs we recognised more than 100 synonymies and made several other taxonomic changes. These are listed and discussed in Eastop & Blackman (2005).
Under each genus name we give a short diagnosis and references to the most recent revisionary accounts. The information given for each species wherever possible includes appearance in life and range of body length (BL) of the apterous vivipara (apt.), host plant(s) and feeding site, distribution, life cycle - including whether the aphid is heteroecious or monoecious and holocyclic or anholocyclic - and times of appearance of oviparae and males, any other systematic or biological information that we consider relevant, and chromosome number (2n female; for further information about aphid karyotypes see Gavrilov-Zimin et al. 2015). Some information about the alate vivipara (al.) may also be provided if this can aid identification. BL gives an indication of size, but for many species this will be based on only a few specimens, and it will only accurately reflect the full size range in the case of better-known species.
For many of the species that occur in Britain we have added links to the excellent colour photographs and much supporting information provided by Bob Dransfield in his online Gallery (see http://influentialpoints.com/sitemap.htm). That website now also includes accounts of many north-eastern North American aphids, with excellent colour photographs provided by Claude Piron. Links are also included at the appropriate points to colour images and notes for many species in western North America on Andy Jensen’s excellent website http://aphidtrek.org/, and to the similarly excellent images and information on southern Indian aphids at https://databases.nbair.res.in/Aphids/index.php.
We have omitted references to original descriptions prior to 1996 as these are available in Remaudière & Remaudière (1997) or, in the case of earlier descriptions, by consulting Smith’s (1972) bibliography after looking up the date of description in Remaudière & Remaudière. We have included references to any significant information about the species published subsequent to its original description, e.g. redescriptions, descriptions of other morphs, or biological studies, the referenced work being mostly limited to taxonomy and variation within and between species. Previously unpublished information on host plant and distribution from slide labels of specimens in the collection of the Natural History Museum (BMNH) is also included. The treatment of economically important species is very selective as information about these is available in Blackman & Eastop (2000), and plenty of more up-to-date information can also be obtained by web searches.
This is an up-dated list of published works on checklists, keys and systematic accounts of aphids. .
