“…Predator odors may or may not affect trapping, feeding, and the use of space of different rodent species, and in some species, such as meadow voles ( Microtus pennsylvanicus Ord), both avoidance and unaltered behavior can be observed . In laboratory T‐maze trials, fox urine has no repelling effect on common voles . Nevertheless, responses can be different if more than one predator is present.…”

BACKGROUND Worldwide, serval rodent species are major pests in agricultural landscapes. A vole‐specific tub‐trap combining trapping and natural predators was developed to minimize the migration of rodents into agricultural crops. The trap was tested in enclosures in terms of its trapability of common voles (Microtus arvalis Pallas) and in the field regarding predator access and removal of voles, both in comparison to a commercially available self‐service trap (standby‐box). RESULTS The trapability of voles was equal for tub‐traps and standby‐boxes. The removal of voles occurred four times more often from tub‐traps by a wider variety of predators (e.g. smaller terrestrial predators, birds of prey). Visits by predators were most likely if study sites were not surrounded by artificial surfaces (70% visit probability by terrestrial predators) or if they were in areas that were more than 25% (semi)natural (95% visit probability by avian predators). Furthermore, visits by avian predators increased with time and a learning effect could be demonstrated for magpies (Pica pica L.). From the first to the fifth day, the visit probability of magpies quadrupled. CONCLUSIONS Visits by predators decreased with increasing cover of artificial surfaces or decreasing cover of (semi)natural areas, proving the importance of (semi)natural areas in the agricultural landscape. Long‐term trials with different baiting techniques and in landscapes characterized by organic farming should be conducted to ensure the regular removal of voles. The use of tub‐traps that are frequently visited by predators could support crop protection, which might limit the use of rodenticide and the associated exposure risk of non‐target wildlife. © 2019 Society of Chemical Industry

Mahlaba et al recently demonstrated that rodents decrease activity when dogs (Canis lupus familiaris L.) and cats are present, but not when only one predator occurs.…”

Pinnipeds, as any mammal species, use multimodal signals, including olfactory ones, to ensure vital functions. Thus, some pinniped species seem able to use olfaction in both social and foraging contexts and to discriminate between different odors in air including both natural and artificial odors, but studies on that topic remain scarce. Here, we studied the olfactory capabilities of California sea lions living in captivity at La Flèche Zoo (France) in both terrestrial and aquatic environments. We used two categories of odors: social odors (from familiar individuals of the same group, unfamiliar individuals from another Zoo, animal zookeepers and a terrestrial carnivore) and non-social odors (food and odors identified as repellents in certain vertebrates). Several behavioral parameters were measured and analyzed as the number and duration of contact with the odor, mouth openings, vocalizations (air only) and air bubble production (water only). Our results, although limited by the low number of animals monitored (n=5), suggest that California sea lions are able to discriminate between different odors both in the air and under water. In the aquatic environment, the process allowing the perception of odors remains to be characterized. Applications to this work could be considered in captive conditions as well as in the wild.

“…Recent advances in ecological research and analytical technology have led to novel methods that use chemical signals to create effective attractants and repellents for pest species [ 11 ]. This potential use of chemical signals for managing pest species is based on the behavioural and physiological responses to intraspecific or predator odours [ 12 – 15 ], to plant secondary metabolites and to toxic substances [ 16 , 17 ].…”

Avoidance behaviour in laboratory house mice (Musmusculus) and Norway rats (Rattus norvegicus) towards predator odours

Mus musculus and Rattus sp. are considered pest species because they reach high densities in urban areas, crop fields and food storage and productive systems such as breeding farms and orchards. Their control relies mainly on rodenticide application, but the effectiveness of this application is reduced due to behavioural responses and resistance. Novel methods are based on the use of chemical signals as odours that may be attractants, repellents or may reduce the reproductive success of pest species. The aim of this paper is to study the aversive effect of TMT, cat urine and cat body odour on predator-inexperienced Mus musculus and Rattus norvegicus under laboratory conditions. The experimental apparatus comprised three boxes connected by PVC pipes in a linear arrangement. In lateral boxes, odour sources or distilled water were introduced, while animals were placed in the central box at the beginning of the experiment. Rats showed freezing behaviour, reduced visits in the presence of TMT and cat fur. Mice reduced their visits with cat body and cat urine. This study provides evidence of the usefulness of using fear responses as a way to control rodent pests, which must be adapted to the environment and species to be applied.
