Domestic dog breeds are hosts for the brown dog tick, Rhipicephalus sanguineus sensu lato, but infestation levels vary among breeds. Beagles are less susceptible to tick infestations than English cocker spaniels due to enhanced production of 2-hexanone and benzaldehyde that act as volatile tick repellents. We report the use of prototype slow-release formulations of these compounds to reduce the burden of R. sanguineus s. l. on English cocker spaniel dogs. Twelve dogs were randomly assigned to two groups with six dogs each. The treated group received collars with slow-release formulations of the compounds attached, while the control group received collars with clean formulations attached. Five environmental infestations were performed, with the number of ticks (at all stages) on the dogs being counted twice a day for 45 days. The counts on the number of tick stages found per dog were individually fitted to linear mixed effects models with repeated measures and normal distribution for errors. The mean tick infestation in the treated group was significantly lower than in the control group. For larvae and nymphs, a decrease in tick infestation was observed at the fifth count, and for adults, lower average counts were observed in all counts. The compounds did not interfere with the distribution of the ticks on the body of the dogs, as a similar percentage of ticks was found on the anterior half of the dogs (54.5% for the control group and 56.2% for the treated group). The biological and reproductive parameters of the ticks were not affected by the repellents. This study highlights for the first time the potential use of a novel allomone (repellent)-based formulation for reduction of tick infestation on susceptible dogs.

1. Crocodilians represent one of the oldest extant vertebrate lineages. They haveco-existed with humans throughout the Amazon basin for thousands of years,often having a strong cultural and economic influence on people's lives. Shifts inthe socio-economic and political reality of the Amazon basin during the last cen-tury have led crocodilian populations to face large variations in their numbersaccording to different levels of exploitation and strategies for their conservation.2. This article reviews the scientific knowledge obtained between 1945 and 2019on the biology, conservation and management for the four Amazonian crocodilian(caiman) species (Caiman crocodilus,Melanosuchus niger,Paleosuchus palpebrosusandPaleosuchus trigonatus). It provides a general overview on past and currentpopulation status and research efforts involving caimans in the Amazon basin anddiscusses perspectives for the future.3. The most significant studies on the ecology, genetics and management strategiesare examined in more detail and this information is contextualized to provide anoverview of the most relevant findings that might explain caiman populationtrends over the last 75 years. 4. Systems for sustainable management in the Amazon basin have been discussedfor the past 20 years, but remain rarely applicable. It is necessary to develop newways to maintain healthy caiman populations through innovative managementprogrammes. Sustainable harvesting of wildlife has been shown to promoteconservation targets, especially those initiatives based on community co-manage-ment. In this article, we propose some general guidelines for future managementschemes, in the expectation that the information provided by the scientificcommunity will be considered fully without political agendas determining thepriorities.
