“…Similarly, Silva et al .

In this case, the authors concluded that differences in the vascular characteristics of the skin of the frog species may determine the variation in their relative attractiveness to frog‐biting midges.…”

Preferences for anuran calls in hematophagous corethrellids (Diptera: Corethrellidae) from Southern Brazil

Corethrellids are hematophagous flies that locate their frog hosts by using their calls as an auditory cue. The attractiveness of frog calls to these insects has been associated with the complexity of the vocalisation or an evolutionary relationship between the fly and frog species. We investigated the possible preferences of a local Corethrella fauna for the calls of six anurans, three species of the genus Boana (Hylidae) and three Physalaemus (Leptodactylidae) species in the Atlantic Rainforest of southern Brazil. We recorded loops of the natural advertisement calls of the different frog host species, which we broadcast from acoustic traps consisting of modified CDC (Center for Disease Control) traps fitted with a speaker under the collecting system, but without a source of light. Nine species of hematophagous flies were captured during 360 h of trapping. Three of the species captured were new to Brazil, and two could not be identified and may represent new taxa. Two corethrellid species contributed 75% of the individuals captured and were present in all the acoustic traps, while three species were attracted to only one trap. The median richness and abundance of corethrellids varied significantly in relation to the different calls broadcast by the traps. These differences in the abundance and species richness of Corethrella in the traps indicate that the frog calls vary in their attractiveness to the hematophagous flies. A model-based analysis using mvabund also indicated that the frog species and genera that produced the calls used in an acoustic trap were a significant factor determining the composition of the Corethrella assemblages captured in that trap. The variation found in the Corethrella communities of southern Brazil may be explained not only by the acoustic traits of frog vocalisations but also by differences in the morphological and ecological characteristics of the frog species.

Light and noise pollution interact to disrupt interspecific interactions

Studies on the consequences of urbanization often examine the effects of light, noise, and heat pollution independently on isolated species providing a limited understanding of how these combined stressors affect species interactions. Here, we investigate how these factors interact to affect parasitic frog-biting midges (Corethrella spp.) and their túngara frog (Engystomops pustulosus) hosts. A survey of túngara frog calling sites revealed that frog abundance was not significantly correlated with urbanization, light, noise, or temperature. In contrast, frog-biting midges were sensitive to light pollution and noise pollution. Increased light intensity significantly reduced midge abundance at low noise levels. At high noise intensity, there were no midges regardless of light level. Two field experiments controlling light and noise levels to examine attraction of the midges to their host and their feeding behavior confirmed the causality of these field patterns. These findings demonstrate that both light and noise pollution disrupt this host-parasite interaction and highlight the importance of considering interactions among species and types of pollutants to accurately assess the impacts of urbanization on ecological communities.

Feeding Site Specificity in Frog-biting Midges (Corethrellidae)

Hematophagous arthropods often choose predictable feeding sites on their hosts´ body, presumably to maximize blood uptake while minimizing costs. Feeding sites can be host-specific, mediated by intrinsic host characters and/or specific preferences of the blood feeder. We investigated feeding site specificity in a community of frog-biting midges (Corethrella spp.) and frog hosts in La Gamba, Costa Rica. Midge distribution on hosts differed significantly between 12 investigated frog species, indicating that intrinsic host properties influence potential feeding sites. However, realized feeding sites were also significantly different between four investigated Corethrella morphotypes, across all hosts but also within certain shared hosts, indicating feeding site partitioning among Corethrella. We propose that the diversity of feeding sites in Corethrella-frog associations is determined by an interaction of host traits, e. g. calling site, defensive behavior or skin thickness, and midge traits, especially body size and corresponding mouthpart size/structure.
