Recent years have witnessed an increase in synanthropic Zygentoma species in Central Europe, with new species being introduced and spreading across the continent [3,4,5,6,7,8,9,10,11]. At the moment, the six species regularly recorded in Central Europe are the common silverfish L. saccharinum, the firebrat Thermobia domestica Packard, 1873, Atelura formicaria Heyden, 1805 (a species living in ant nests), and three recently introduced species: the invasive gray or long-tailed silverfish Ctenolepisma longicaudatum Escherich, 1905, the four-lined silverfish C. lineatum (Fabricius, 1775), and C. calvum (Ritter, 1910). A. formicaria is mainly restricted to habitats outside of buildings [12], while all other species are mostly related to human activity and found interiors. C. lineatum is also found outside of buildings in some European countries; it is a facultative synanthropic species. Additionally, Coletinia maggii (Grassi, 1887) is mentioned uniquely in Austria [13]. Nicoletia phytophila Gervais, 1844, Stylifera impudica Escherich, 1905, Gastrotheus ceylonicus (Paclt, 1974), and Ctenolepisma rothschildum Silvestri, 1907 have been reported at least once in Germany [14], but they are not known as common insects in homes and buildings.

Silverfish are indoor pests in homes, offices, museums, and galleries, causing harm to objects such as paper, books, photographs, and wallpaper [15,16,17,18,19,20,21]. They are, thus, an important target of investigation (monitoring with traps) and integrated pest management [15,18,20]. The insects are rather shy and night-active; thus, they are often overlooked. In museums, C. longicaudatum is a recognized pest, where it has damaged a number of objects in recent years. Although such risks are known for L. saccharinum, the species seldom causes damage to objects. It requires high humidity (>70% RH); hence, only paper-based material stored in damp rooms and on the ground can be damaged. Aak et al. [3] showed a widening spread and particularly northward movement of the long-tailed silverfish C. longicaudatum in Norway. In homes, most silverfish (Zygentoma) are not real pests, but only nuisance animals.

Eco PCO D-X dust is an all-natural organic insecticide dust that is versatile and ready-to-use. Unlike many other organic dusts, Eco PCO D-X is unscented, non-staining, non-clumping and water-resistant. It provides a quick knockdown and kill of insect pests and leaves a long lasting residual. Eco PCO DX works on ants, bed bugs, carpet beetles, centipedes, fleas, silverfish, scorpions, spiders and more. Can be used both indoors and outdoors.

Ants, bedbugs, carpet beetles, centipedes, cockroaches, crickets, darkling beetles, earwigs, hide beetles, firebrats/silverfish, fleas, millipedes, sowbugs/pillbugs, spiders, scorpions, and other indoor/outdoor insect pests; wasps, yellow jackets and other stinging insects.

Social insect nests provide a safe and favourable shelter to many guests and parasites. In Aphaenogaster senilis nests many guests are tolerated. Among them we studied the chemical integration of two myrmecophile beetles, Sternocoelis hispanus (Coleoptera: Histeridae) and Chitosa nigrita (Coleoptera: Staphylinidae), and a silverfish. Silverfishes bear low quantities of the host hydrocarbons (chemical insignificance), acquired probably passively, and they do not match the colony odour. Both beetle species use chemical mimicry to be accepted; they have the same specific cuticular hydrocarbon profile as their host. They also match the ant colony odour, but they keep some specificity and can be recognised by the ants as a different element. Sternocoelis are always adopted in other conspecific colonies of A. senilis with different delays. They are adopted in the twin species A. iberica but never in A. simonellii or A. subterranea. They are readopted easily into their mother colony after an isolation of different durations until one month. After isolation they keep their hydrocarbons quantity, showing that they are able to synthesize them. Nevertheless, their profile diverges from the host colony, indicating that they adjust it in contact with the hosts. This had never been demonstrated before in myrmecophile beetles. We suggest that the chemical mimicry of Sternocoelis is the result of a coevolution with A. senilis with a possible cleaning symbiosis.

In the present study we conducted a survey of all arthropods living in the nest of the gipsy ant Aphaenogaster senilis in southern Spain. Then, we compared the chemical integration of two myrmecophiles beetles (Sternocoelis hispanus and Chitosa nigrita) with that of an undetermined silverfish. We hypothesized that guests specialized with only one host (like Sternocoelis) have coevolved with it and biosynthesize the hydrocarbons while host-generalists like silverfish would mimic passively their hosts and can shift easily to different host species. To test for host specificity and relate it to chemical distance, we designed adoption experiments with Sternocoelis in conspecific colonies and congeneric species. We then analysed the mechanisms of chemical mimicry looking at the effects of separation of the beetles from their host. After two weeks, the exogenous hydrocarbons of the myrmecophile beetle Myrmecaphodius begin to disappear [15]. Therefore, after one-month isolation, we supposed that all exogenous hydrocarbons acquired by contact with ants had disappeared. As Sternocoelis was frequently observed licking the ant larvae, we investigated possible roles of these beetles in larval predation or prophylaxis. If the beetles fed on larvae by piercing the cuticle (haemolymph feeding on larvae by ant workers is known in Amblyopone [16]), larvae were supposed to decline. On the contrary, if the beetles fed only by licking the cuticle, larvae will maintain their wellbeing.

We completely excavated 57 nests between February 2008 and December 2009 on the banks of Guadalquivir near Sanlúcar de Barrameda to list and count all the guests, mites, silverfish, sowbugs, staphylinids, and histerid beetles.

They are very active insects moving rapidly into the nest. Very little is known on their biology. Since they are associated with various ant species, they are apparently host generalists. Chitosa nigrita is a rare myrmecophilous species known only from Spain and Morocco [20] (Figure 2). We collected C. nigrita in two colonies of A. senilis (1 and 4). From colony 4 we also collected two silverfish. Silverfish are known to move freely within the entire nest [6]. Chitosa and silverfish were only used for chemical analyses.

We did not quantify the behaviour of the other guests, but observations indicated that Chitosa beetles and silverfish had a very different behaviour compared to Sternocoelis: they had very few interactions with the host, moving frequently in the nest. Silverfish were very fragile and died in less than 24 hours in the laboratory nests.

Sternocoelis, Chitosa and silverfish had the same hydrocarbons as their host Aphaenogaster senilis (Figure 4 and Table 2). Aphaenogaster iberica and A. simonellii also had the same hydrocarbons as A. senilis (Nei indexes were close: A. senilis/A. iberica = 0.75; A. senilis/A. simonellii = 0.65; A. iberica/A. simonellii = 0.88). A. subterranea had a very different profile with very small quantities of hydrocarbons (using total peak areas) and 20% of unsaturated alkanes which were absent in all other species. Surprisingly, it has also a lot of heavy hydrocarbons (25.8% had more than 32 carbons) that were not found in other species. This species is mostly subterranean and lacks saturated hydrocarbons protecting against desiccation. The Nei index between A. subterranea and the other Aphaenogaster species is very low (0.211), indicating a high chemical disparity. Therefore, this ant species has not been included in the following analyses.

In the first analysis we constructed a dendrogram of chemical distances between the guests and their Aphaenogaster host. It appeared clearly that the four A. senilis colonies had different profiles (Figure 5), confirming previous analyses [30]. All the beetles, both Sternocoelis and Chitosa, were grouped with their host colony, indicating a chemical mimicry fitting the colonial signature. Nevertheless, beetles aggregated distinctly from their host. The chemical distance between colonies did not depend on their geographical distance, and was not linked to the beetle adoption time. Colonies 2 and 3 were equally chemically distant to colony 1 but accepted the beetles more or less rapidly. Aphaenogaster iberica and A. simonellii were close to A. senilis colonies 2 and 3 (data not shown) but the first species accepted the beetles whereas the second did not (but only 4 adoption trials). On the contrary, the silverfish did not match the host colony. Interestingly, Sternocoelis adopted in A. iberica were close to their new host but did not match completely to the new colony. A. subterranea is very different and as expected never adopted the beetles. 041b061a72
