Identification & Distribution

Adult apterae of Cinara nigritergi are dark brown with extensive pleural grey wax markings, and are sometimes wax powdered along the dorsal midline. There is a large dull or subshining sclerite encompassing the siphunculi, and usually extending anteriorly to the mesothorax, with a separate transverse band on tergite VII (cf. Cinara brauni, which has a dorsal sclerite extending across abdominal tergites V-VII only, with a separate transverse band on tergite VIII; also cf. Cinara pini and Cinara acutirostris, on Pinus, which do not have any sclerites that are fused between segments, nor fused with the siphuncular cones). Hairs on the appendages and body are short, and rather sparse, as in Cinara pini (cf. Cinara pinihabitans, which has hairs that are denser and longer than in most pine-feeding Cinara species). The siphuncular cones are large and dark. The body length of adult Cinara nigritergi apterae is 2.54.0 mm.

Note: The large dull dorsal sclerite appears rather faint on live aphids (see first picture below), although it is clearly visible on freeze-dried specimens (see second picture below) and clarified slide mounts.

Cinara nigritergi is monoecious on pine (Pinus spp), mainly (or possibly only) on Scots pine (Pinus sylvestris). It lives in open forests on sand or rock, meadow margins, pine plantations, and sea shores. The species is holocyclic with the ovipara having a perianal wax ring. Like many other Cinara species, it is usually attended by ants (see picture above). Species of ants so far recorded as attending this aphid are Lasius niger and Lasius fuliginosus (Albrecht, 2017). The black-backed pine aphid has so far been found in Russia, Sweden, Ukraine, Czech Republic and Kazakhstan.


Other aphids on the same host

Cinara nigritergi has been recorded from only 2 pine species (Pinus sylvestris, Pinus uncinata).

Blackman & Eastop list 30 species of aphid as feeding on Scots pine (Pinus sylvestris) worldwide, and provide formal identification keys. (Show World list). Of those aphid species, Baker (2015) lists 15 as occurring in Britain (Show British list).


We are grateful to Anders Albrecht for making his images of Cinara nigritergi available for use under a creative commons licence.

We have used the species accounts and keys given by Albrecht (2017), together with information from Roger Blackman & Victor Eastop in Aphids on Worlds Plants. We fully acknowledge these authors and those listed in the reference sections as the source for the (summarized) taxonomic information we have presented. Any errors in information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006).
