Data from: Host social behavior decreases exposure to vector-borne disease: a field experiment in a "hotspot" of West Nile virus transmission
Animals can decrease their individual risk of predation by forming groups. The encounter-dilution hypothesis extends the potential benefits of gregariousness to biting insects and vector-borne disease by predicting that the per capita number of insect bites should decrease within larger host groups. Although vector-borne diseases are common and can exert strong selective pressures on hosts, there have been few tests of the encounter-dilution effect in natural systems. We conducted an experimental test of the encounter-dilution hypothesis using the American robin (Turdus migratorius), a common host species for the West Nile virus (WNV), a mosquito-borne pathogen. By using sentinel hosts (house sparrows, Passer domesticus) caged in naturally occurring communal roosts in the suburbs of Chicago, we assessed sentinel host risk of WNV exposure inside and outside of roosts. We also estimated per capita host exposure to infected vectors inside roosts and outside of roosts. Sentinel birds caged inside roosts seroconverted to WNV more slowly than those outside of roosts, suggesting that social groups decrease per capita exposure to infected mosquitoes. These results therefore support the encounter-dilution hypothesis in a vector-borne disease system. Our results suggest that disease-related selective pressures on sociality may depend on the mode of disease transmission.
Data from: Discovery and exploitation of a natural ecological trap for a mosquito disease vector
Ecological traps occur due to a mismatch between a habitat's attractiveness and quality, wherein organisms show preference for low-quality habitats over other available high-quality habitats. Our previous research identified leaf litter from common blackberry (Rubus allegheniensis) as a natural ecological trap for an important vector for West Nile virus (Culex pipiens), attracting mosquitoes to oviposit in habitats deleterious to the survival of their larvae. Here we demonstrate that manipulation of leaf litter in stormwater catch basins, an important source of disease vector mosquitoes in urban environments, can increase Cx. pipiens oviposition but reduce survival. In a series of experiments designed to elucidate the mechanisms that explain the attractive and lethal properties of this native plant, behavioral bioassays suggest that oviposition site selection by Cx. pipiens is mediated primarily by chemical cues as leaves decompose. However, we also show that juvenile mosquito survival mainly is related to the suitability of the bacterial community in the aquatic habitat for mosquito nutritional needs, which does not appear to create a cue that influences oviposition choice. This mismatch between oviposition cues and drivers of larval habitat quality may account for the ecological trap phenomenon detected in this study. Our findings provide new insights into potential mechanistic pathways by which ecological traps may occur in nature and proof-of-concept for a new 'attract-and-kill' tool for mosquito control.

Data from: "Transcriptome sequence identity between Lyme disease tick vectors, Ixodes scapularis and Ixodes ricinus" in Genomic Resources Notes accepted 1 April 2014 to 31 May 2014
Ixodes scapularis and I. ricinus transmit the Lyme disease agent Borrelia burgdorferi in the U.S. and Europe, respectively. The only tick genome sequence available is that of I. scapularis, which constitutes a limitation for tick research. Recent evidences suggest that I. ricinus and I. scapularis transcriptomes share some degree of sequence identity. However, only the global transcriptome comparison reported here demonstrated that I. ricinus and I. scapularis share a 99.232±0.005 percent sequence identity with a very low frequency of INDELs. However, due to limitations of the current I. scapularis genome assembly, the number of aligned reads was only 26-27%. These results support the use of I. scapularis genome sequence as a reference for the analysis of I. ricinus transcriptomics and proteomics data, but addressing the limitations associated with the I. scapularis genome assembly.
