Soldiers effectively defend aphid colonies against predators in the field.
Foster WA, Rhoden PK. Foster WA, et al. Anim Behav. 1998 Mar;55(3):761-5. doi: 10.1006/anbe.1997.0664. Anim Behav. 1998. PMID: 9514674
To study the effectiveness of soldiers of the gall-forming aphid, Pemphigus spyrothecae Pass., in protecting their galls against natural levels of predation, we manipulated the proportions of soldiers and non-soldiers in sets of galls still attached to poplar trees …

Poplar Tree Response to Feeding by the Petiole Gall Aphid Pemphigus spyrothecae Pass.
Kot I, Kmieć K. Kot I, et al. Insects. 2020 May 5;11(5):282. doi: 10.3390/insects11050282. Insects. 2020. PMID: 32380670 Free PMC article.
Pemphigus spyrothecae Pass. which is a member of the subfamily Pemphiginae is one of the gall-inducing aphids that occurs on poplar trees. ...

Petiole gall aphid (Pemphigus spyrothecae) infestation of Populus petrovskiana leaves alters foliage photosynthetic characteristics and leads to enhanced emissions of both constitutive and stress-induced volatiles.
Ye J, Jiang Y, Veromann-Jürgenson LL, Niinemets Ü. Ye J, et al. Trees (Berl West). 2019 Feb;33(1):37-51. doi: 10.1007/s00468-018-1756-2. Epub 2018 Sep 3. Trees (Berl West). 2019. PMID: 31700201 Free PMC article.
Poplar spiral gall aphid (Pemphigus spyrothecae) forms galls on the petiole in poplars (Populus) and mass infestations are frequent in poplar stands, but how these parasite gall infestations can affect the leaf lamina structure, photosynthetic rate and constitutive …

Molecular characterization of the leucine cluster in Buchnera sp. strain PSY, a primary endosymbiont of the aphid Pemphigus spyrothecae.
Sabater-Muñoz B, Gómez-Valero L, van Ham RC, Silva FJ, Latorre A. Sabater-Muñoz B, et al. Appl Environ Microbiol. 2002 May;68(5):2572-5. doi: 10.1128/AEM.68.5.2572-2575.2002. Appl Environ Microbiol. 2002. PMID: 11976137 Free PMC article.
Here, however, we demonstrate a classical chromosomal location of the cluster in Buchnera sp. strain PSY from the aphid Pemphigus spyrothecae (subfamily Pemphiginae). The genes that flank leuABCD in Buchnera sp. strain PSY appear to be adjacent in the genome of Buch …

Changes in clonal poplar leaf chemistry caused by stem galls alter herbivory and leaf litter decomposition.
Künkler N, Brandl R, Brändle M. Künkler N, et al. PLoS One. 2013 Nov 19;8(11):e79994. doi: 10.1371/journal.pone.0079994. eCollection 2013. PLoS One. 2013. PMID: 24260333 Free PMC article.
We analysed the impact of gall infestation by the aphid Pemphigus spirothecae on chemical leaf traits of clonal Lombardy poplars (Populus nigra var. italica) and the subsequent effects on intensity of herbivory and decomposition of leaves across five sites. ...

Plasmid-encoded anthranilate synthase (TrpEG) in Buchnera aphidicola from aphids of the family pemphigidae.
Van Ham RCHJ, Martínez-Torres D, Moya A, Latorre A. Van Ham RCHJ, et al. Appl Environ Microbiol. 1999 Jan;65(1):117-25. doi: 10.1128/AEM.65.1.117-125.1999. Appl Environ Microbiol. 1999. PMID: 9872768 Free PMC article.
The second plasmid (pBPs2), isolated from Buchnera of Pemphigus spyrothecae, contained a different replicon. It consisted of a putative origin of replication containing iterons and an open reading frame, designated repAC, which showed a high similarity to the gene e …

Clonal mixing in the soldier-producing aphid Pemphigus spyrothecae (Hemiptera: Aphididae).
Johnson PC, Whitfield JA, Foster WA, Amos W. Johnson PC, et al. Mol Ecol. 2002 Aug;11(8):1525-31. doi: 10.1046/j.1365-294x.2002.01530.x. Mol Ecol. 2002. PMID: 12144671
Illuminating the genetic relationships within soldier-producing aphid colonies is an essential element of any attempt to explain the evolution of the altruistic soldier caste. Pemphigus spyrothecae is a soldier-producing aphid that induces galls on the leaf petioles …

Specialised placement of morphs within the gall of the social aphid Pemphigus spyrothecae.
Pike N. Pike N. BMC Evol Biol. 2007 Feb 13;7:18. doi: 10.1186/1471-2148-7-18. BMC Evol Biol. 2007. PMID: 17298667 Free PMC article.
To examine if this advanced social phenomenon might apply to social aphids, the location of the numerous morphs within the nests (plant galls) of the aphid species Pemphigus spyrothecae was examined. RESULTS: A strong, almost exclusive tendency for soldiers to occup …
