“…Concerning the study on the preferences of water mites for the host sex, the conclusion varies in some cases. No differences in the prevalence due to host sex were sometimes recorded (Martin and Stur 2006;Robb and Forbes 2006;Fairn et al 2008;Zawal and Buczyński 2013;Sánchez et al 2015). On the contrary, female hostbiased prevalence was reported by Yasick et al (2003), Zawal (2006a), Baker et al (2008), Zawal and Daytlova (2008), Radhakrishnan et al (2010), and Kulijer et al (2012).…”

Water mites are known to temporarily live on the surface of aquatic insects in their life cycle. Investigations of the host-parasite relationship between water mites and aquatic insects are quite limited in Japan. Therefore, we examined several aquatic hemipterans to clarify the parasitic nature of water mites on aquatic insects. During the survey, the following seven hemipteran species were collected from farm ponds and rice fields in Kanagawa, Yamanashi, and Hyogo prefectures in 2011 and 2012: Appasus japonicus, Appasus major, Laccotrephes japonensis, Aquarius paludum, Ranatra chinensis, Kirkaldyia deyrolli, and Notonecta triguttata. Among these species, water mites were found only on Ap. japonicus and R. chinensis. The water mites were all in a post-larval resting stage and identified as Hydrachna spp. The mites attached to R. chinensis were clearly larger than those on Ap. japonicus. Although mites do not select by host sex and their abundance was not affected by the host body size, their abundance per female host was greater than per male host. Further, the mite parasitism on nymphs was greater than that on adults in Ap. japonicus. Concerning site selection on a host body of R. chinensis for attachment, mites significantly prefer the leg and meso-and metathoraxes to the abdomen, respiratory siphon, and head of a host insect. The results mentioned above accorded well with several studies in Europe.

“…Our results show that freshwater salinisation can influence both individual host–parasite interactions and the effects of parasites on host populations. Several previous studies have found reduced parasite success in high salinity environments (Miron et al., ; Sanchez et al., ; Stockwell et al., ), suggesting that our result of lower infection prevalence in high salinity may be a common phenomenon. For introduced or emerging parasites, reducing infection prevalence with high salinity may be desirable if the host species is under threat and able to withstand high salinity.…”

Temperate freshwater ecosystems are currently being salinised through anthropogenic activities. These increases in freshwater salinity can impact individuals, populations, and species interactions. We studied the effects of salinity on freshwater host–parasite interactions at multiple scales using the zooplankton host, Daphnia dentifera, and a fungal parasite (Metschnikowia bicuspidata). We conducted one experiment at the individual‐level to quantify the effects of salinity on infection prevalence and another to understand the combined population‐level effects of salinity and parasitism. In our first experiment, we found that the effects of salinity on infection prevalence varied by host genotype; increased salinity reduced infection prevalence in one genotype but had no effect on infection prevalence in another. In our second experiment, infection prevalence was lower when NaCl was added to the microcosms compared to the control (no added salt) treatments. We also found a significant parasite × salinity interaction on D. dentifera density in our second experiment, where the parasite only reduced host densities in our control treatment, probably due to the reduced infection prevalence as salinity increased. This study demonstrates that salinity can influence infection prevalence in freshwater hosts and that host population density may respond to the combined effects of salinisation and parasitism in a non‐additive manner.

Biological invasion modifies the co‐occurrence patterns of insects along a stress gradient

Summary Biological invasions have become one of the most important drivers of biodiversity loss and ecosystem change world‐wide. However, it is still unclear how invasions may interact with local abiotic stressors, which are expected to increase as global change intensifies. Furthermore, we know little about the response to biological invasions of insects, despite their disproportionate contribution to global animal biodiversity. The aim of the present work is to investigate the impact of an invasive aquatic insect on the co‐occurrence patterns of native species of insects along a salinity gradient, and determine which assembly rules are driving these patterns. First, we characterised the habitat specialisation and functional niches of each species from physiological and biological traits, respectively, and their degree of overlap. Second, we used field data to compare the co‐occurrence patterns of native and invasive species in invaded and non‐invaded areas of southern Iberia and northern Morocco. Finally, we tested if habitat filtering or niche differentiation assembly rules mediate their co‐occurrence. In non‐invaded areas, habitat filtering drives habitat segregation of species along the salinity gradient, with a lower contribution of niche differentiation. The presence of the invasive insect modifies the distribution and co‐occurrence patterns of native species. In invaded areas, niche differentiation seems to be the main mechanism to avoid competition among the invasive and native species, enabling coexistence and resource partitioning. The combined study of functional niche similarity and abiotic stressor tolerance of invasive and native species can improve our understanding of the effects of invasive species along abiotic stress gradients. This approach may increase our capacity to predict the outcomes of biological invasion in a global change context.
