abstract = {Mutualistic relation with ants is one of the leading features of aphid ecology. For some aphid species, it is a crucial association enhancing their survival capability, while the life mode of some others is completely independent of ants. It was broadly accepted that during the evolution of aphids, the ones relying on ants developed special morphological adaptations for this mutualism, the so-called trophobiotic organ. Its exact structuring, however, posed some explanatory difficulties because many non-myrmecophilous aphids had structural modifications accordant with the trophobiotic organ, while some myrmecophilous did not. Here we present an evaluation of the morphology of perianal structures in 25 non-myrmecophilous aphid species with reference to previous, similar studies on myrmecophilous species based on scanning electron microscopy. We conclude that the trophobiotic organ is an existing adaptation, but its definition requires revision. © 2023 by the authors.},

abstract = {There are three types of relationships between aphids and ants: non-myrmecophilous, obligatory and facultatively myrmecophilous. The degree of involvement in this mutualism is believed to be corelated with morphological adaptations of perianal structures. In this manuscript, we analyzed the differences of these structures in obligatorily (18 species) and facultatively (10 species) myrmecophilous aphids. Scanning electron microscopy (SEM) and light stereoscopic microscopy (LSM) techniques were used for these studies. Comparison of structures showed no strict relationship between their morphology and the degree myrmecophily, with certain indication that the microsculpture of perianal cuticle may play role in protection of aphids against honeydew droplet in facultatively myrmecophilous aphids. © 2022 by the authors.},

abstract = {Among mutualistic relationships of aphids with other organisms, there are two that seem to be of major importance: trophobiosis with ants and endosymbiosis of bacteria. While the former is well studied, the latter is the subject of an increasing amount of research constantly revealing new aspects of this symbiosis. Here, we studied the possible influence of ant attendance on the composition of aphid microbiota on primary and secondary hosts exploited by the aphid genus Dysaphis. The microbiome of 44 samples representing 12 aphid species was studied using an Illumina HiSeq 4000 with the V3-V4 region of 16S rRNA. The results showed a higher abundance of common facultative symbionts (Serratia; Regiella; Fukatsuia) in aphid species unattended by ants, but also on secondary hosts. However, in colonies attended by ants, the general species composition of bacterial symbionts was more rich in genera than in unattended colonies (Wolbachia; Gilliamella; Spiroplasma; Sphingomonas; Pelomonas). The results indicate a huge variability of facultative symbionts without clear correlation with ant attendance or aphid species. The possibility of multiple routes of bacterial infection mediated by ant-made environmental conditions is discussed. © 2022 by the authors.},

This broad literature review allows us to revise existing views on certain aspects of this mutualism and provide the first timeline of its possible development over a geological timescale. We propose a new classification of ant–aphid mutualism with respect to its ecological characteristics and present new explanations of the development of certain morphological structures of aphids as resulting from adaptation to a trophobiotic relationship with ants. In light of these findings, the presence of the so-called ‘trophobiotic organ’ in all myrmecophilous aphids is questioned. We review various communication modes between aphids and mutualistic ants and the possible influence of this symbiosis on modifications of aphid life cycles. Recent evidence on the suspected role of endosymbiotic bacteria in the development of mutualism is discussed. Finally, we propose a first timeline of ant–aphid interactions leading to the development of particular adaptations of aphids to mutualism, from general interactions between diverging Aphidomorpha and ants in the late Mesozoic to more specific coevolution between the aphid tribe Fordini and the ant genus Lasius. © 2020 Cambridge Philosophical Society},

abstract = {Stomaphis Walker is an obligatorily myrmecophilous, tree-trunk feeding aphid genus, having many peculiar features in its morphology. One poorly studied trait is its perianal anatomy, with suspected existence of trophobiotic organ and intriguing tubercles near abdominal segment VIII. Tubercles on rear end of abdomen in Stomaphis were considered to be marginal tubercles, structure typical of aphids. Only after their investigation under scanning electron microscope they revealed to possess a very rough surface, consisting of many protuberant, sclerotic scales with finger-like processes. Analysis and comparison with other aphids suggests, that these structures – perianal tubercles – may be considered remnants of abdominal sternite IX, atrophied in aphids. Due to their similarity to the surface of cauda of non myrmecophilous aphids, they are suspected to serve as sort of auxiliary caudas, protecting from sticky secretions of aphids e. g. honeydew or mucus while giving birth or ovipositing in confined space. A very well developed trophobiotic organ in this genus has been shown to exist for the first time. © 2020},

abstract = {Dwarfish males are a relatively common phenomenon in animals, occurring in various taxa, most often when females conduct a sedentary life mode. Such males, beside smaller size, exhibit a series of morphological and anatomical alterations, mostly structural reductions. Here we present the case of the alimentary tract of dwarfish males of the aphid genus Stomaphis where, despite it being structurally normal, it does not serve its original function due to a lack of mouthparts. Cross-sections through mounted specimens revealed also that nervous and reproductive systems are fully developed. The question arises as to whether such a system may be considered vestigial, or an exaptation with secondary function shifted to play new primary function. Because the aphid genus Stomaphis is known from the fossil record to have existed for at least ca. 14 My and all of its species have dwarfish, arostral males, this indicates that it may be too short a period for reduction of the whole system. It also raises questions about the mechanisms of loss of the primary functionality of the whole physiological unit, and the influence of such modification on the evolution of its phylogenetic successors. Secondary functions of the tract are speculated to be responsible for its endurance. © 2020 Copyright 2020 by Kaszyca-Taszakowska et al.},

The shape of wax secretions and wing margins is described. The comparative analysis of forewing structures contains new data for all Sternorrhyncha infraorders. The current results confirm the monophyly of the group, but place aphids closer to psyllids. The analysis of forewing base indicates that its general model is similar among Sternorrhyncha, but there occur some intergroup differences.

The large interspecies variation of observed responses can be linked to other defensive mechanisms existing in the studied species, as well as to their mutualistic relationship with ants. The behaviour of shrinking is hypothesized to be the mutualistic response, developed from thanatosis, and being adapted to transportation by ant workers. © 2018, The Author(s).},

We examined and compared the external morphology in the parthenogenetic generation living on roots of deciduous plants. FE-SEM images based on HMDS preparation techniques revealed great similarity of perianal structures even between not closely related groups. Rectangular, vertically positioned anal plate, extremely shortened cauda and setae around the anus seem to be common features of these aphids. However, some differences in the number and length of setae, their arrangement and inclination of anal plate may be observed. The discussion focuses on the adaptive importance of such modifications, with respect to underground life mode and myrmecophily, but with reservations concerning living in galls by representatives of Eriosomatinae, which is hypothesized to be a factor driving the development of such modifications of perianal structures in this group of aphids. © 2017 Elsevier Ltd},

abstract = {Ecological divergence is an accepted mode of speciation in phytophagous insects such as aphids. Adaptations of ancestral populations to various feeding locations on a plant seem to be a promoted mode of such speciation. In this study we present a thesis that for obligatorily myrmecophilous aphids it is a mutualistic relationship with distinct ants that constitutes a significant selective factor. It leads to the separation of ecological niches of ancestral aphid populations and development of sibling species. The thesis is supported by the example of two sibling aphid species of the genus Stomaphis, S. quercus (L.) and S. wojciechowskii Depa, which show very peculiar adaptations to feeding on trees and are both undoubtedly obligatorily myrmecophilous species. Their separateness is proven by mitochondrial markers, as well as their life modes and ecological adaptations: they all follow the biology of their respective ant hosts: Lasius (Dendrolasius) fuliginosus and L. (L.) brunneus. Proven and modelled geographical distributions indicate a high level of sympatry and the fact that environmental requirements of both aphid species overlap. It is suggested that their divergence has resulted from having adapted to living with ants of distinct life modes, foraging strategies and positions in the hierarchy of ant assemblages. This, in turn, indirectly affected their adaptations to exploit different host plant genera. © 2016 The Linnean Society of London.},

The study aimed at repeated anatomical research of Geoicautricularia (Passerini 1856), in order to confirm what seemed to be a generic feature. Standard histological methods were applied, with addition of oblique light microscopy, fluorescence microscopy and confocal laser scanning microscopy. The results indicated the existence of a fully developed intestine, with broad sac-shaped stomach and loops of the crenated intestine. The general anatomy of the alimentary tract of G. utricularia resembles that of other representatives of the tribe Fordini. Also well-developed rectal gland is present, most probably playing a role in modifying the carbohydrate composition of excreted honeydew. © 2016, The Author(s).},

The results of morphological analysis were confirmed with molecular markers, so L. longirostris (Mordvilko; 1909) was synonymized with L. pallipes (Hartig; 1841), and the neotype of L. pallipes was designated.

abstract = {Firm matching of genitals during copulation is of critical importance to effective insemination and thus, gene flow. During the evolution of insects, an effective position during copulation promoted higher fecundity through control over the act of mating or elimination of competitors. Usually during insect copulation, either twisting or flexing of the male abdomen occurs, and genitals remain symmetrically or asymmetrically disposed following changes in the mating position. However, it is always the dorsal side of the male genitalia that makes contact with the ventral side of female abdomen. Here we present the unusual case of a 'belly-to-belly' copulation, with symmetrically positioned male genitals and no twisting of the abdomen. During the mating of two species in the Stomaphis genus of large, tree dwelling aphids, the dwarfish male is attached to the underside of the female, with the ventral part of its genitals contacting the ventral part of female abdomen, and the aedeagus effectively inserted into the female genital organs. Interestingly, congeneric species do not exhibit this sort of mating, but differences in the genital plates of females, between species, may play an important role. These observations raise many questions concerning the possible dominant role of the female during mating and later, during mate guarding by male, which can lead to monandry in this generally polyandrous group of insects. It is possible that this sort of mating is either an adaptation to the competitive behaviour of other males or a consequence of the obligatory mutualistic relationship with ants, and the adaptation to specialised ecological niches enforced by this relationship. If ants do influence the mating habits of Stomaphis then it is possible that speciation in this group of insects, and phytophagous insects generally, is partially driven by their relationship with ants.},

Aphids of the genus Stomaphis are remarkable for their large body size, but due to their discreet feeding positions, knowledge of their biology remains fragmentary. Observations conducted during a period of two years were used to infer the life-cycle of Stomaphis graffii Cholod., an abundant species in parks and forest-stands in southern Poland. Observations indicate the occurrence of the first generation as early as at the end of April and the generation of alate females throughout July and August. Sexual generation occurs in late August and oviposition takes place from the end of September through to October. At the turn of October and November, apart from oviparous females, some larvae are still present in colonies. Meteorological data provided for the period of hatching of first larvae indicates correlation of this phenomenon with the phenology of the host plant rather than directly with the weather. Presented data are further compared with the biology of other representatives of the genus Stomaphis with reference to their habitat requirements. © 2013 Koninklijke Brill NV, Leiden.},

abstract = {In Europe, there are three aphid species of the genus Stomaphis Walker that feed on trees in the genus Acer and one that feeds on trees in the family Salicaceae. Although these species are considered morphologically distinct, their uncertain host specificity and variation in morphological features has led to misidentifications or questionable attribution of subspecies status. The aim of the present study was to clarify the identity of the Central European representatives on the basis of morphological and molecular analyses. Our study is based on 42 samples from Central Europe and Northern Italy. Mitochondrial markers COXI and COXII were used to determine the molecular identity of the specimens studied. Our molecular analyses revealed the existence of three clades (two on Acer; one on Salicaceae) as defined by both molecular markers. Morphological analysis showed a broad range of variability of the key morphological features in all three clades. Despite significant differences in the mean values of morphometric traits, their range of variability strongly overlapped. Samples from COXI clades on Acer showed two different patterns of geographical distribution. Host specificity is recognized only at the level of host plant genera (Acer) and family (Salicaceae), excluding the possibility of the existence of separate subspecies on single host plant species. © 2013 Zoological Society of Japan.},

abstract = {The paper presents data on the remarkable abundance of S. graffii in the parks of the industrially transformed region of Upper Silesia, Poland. Ten new sites and 36 colonies were recorded, while only 6 sites were known so far from the whole territory of Poland. New host plant species and new ant species tending aphids were also recorded. The conclusion is that the abundance of Stomaphis species may be underestimated due to their cryptic life mode. © 2012 Versita Warsaw and Springer-Verlag Wien.},

abstract = {The two species of the genus Stomaphis feeding on oak and birch, respectively, although morphologically similar, are considered to be separate species. However, the birch-feeding S. betulae Mamontova is considered to be a synonym of the oak and birch feeding S. quercus (L.) by some authors. The purpose of this study was to determine whether the birch feeding and oak feeding populations attributed to S. quercus belong to the same species. The mitochondrial cytochrome-c oxidase I (COXI) and II (COXII) were used to determine whether these two populations differ. There are no significant differences in these markers from oak and birch feeding individuals, indicating that these populations are conspecific. However, morphologically and ecologically distinct populations of Stomaphis were discovered feeding on oak. The molecular analysis confirmed that these populations are distinct, which resulted in the description of the new oak-feeding species, Stomaphis wojciechowskii Depa, sp. n. This new species previously remained unrecognized due to its very cryptic mode of life.},

abstract = {The paper presents the comparison of species diversity and evenness indices calculated for coexisting communities of aphids and ants. In six study areas, localised in Upper Silesia (Poland), representing acidophilous oak-forest (Molinio caeruleae-Quercetum roboris), moist meadow (Molinietum caeruleae) and xerothermic grassland (Sileno-Phleetum) the community structure of aphids and ants (species number and abundance) was determined. The number of ant nests and aphid colonies was determined by searching the squares of 25 m2 during vegetation seasons in 2006 and 2007. This provided the base to calculate the Shannon's diversity index and evenness index of both groups. Spearman's rank correlation analysis showed significant correlation only in the case of the number of species of both groups in a particular study area. It showed no significant correlation of values of diversity and evenness indices; however, considerable differences of values between both groups in various habitat types were recorded. The results are discussed with reference to the habitat history and maintenance, also reflecting the mutualistic relationship between ants and aphids.},
