Influence of environmental factors on tick diversity and abundance in different animal resting habitats in forest areas of the south Western Ghats.

Most tick-borne disease causing pathogens originate in wildlife and are zoonotic in nature. A key to protecting human and animal health is to understand the biology and ecology of tick establishment. The tick distribution in wild animal habitats has been attributed to multiple environmental factors, and the studies on this topic are limited. Therefore, the objective of the study is to understand the influence of environmental factors on tick diversity and abundance in wild animal resting habitats. The study was carried out in 21 different animal resting habitats in the forest areas of Wayanad district, and they were divided into three groups based on the presence or absence of selected environmental parameters. A total of 10,849 ticks with 12 species belonging to five genera were collected. Regardless of the type of habitats, Haemaphysalis spinigera (59.52%) and Haemaphysalis turturis (33.20%) were the dominant species. Tick abundance showed greater variability between types of habitats ranging from 1.23 to 28.5. The greatest diversity and abundance were found in the group one. The group 3 had greater diversity and less abundance than the group 2. Both Simpson's diversity index and Shannon's diversity index were high for groups 2. Substantial variation in diversity and abundance of ticks occurred in different groups based on different environmental factors. The dominance of ticks of the genus Haemaphysalis a primary vector of Kyasanur Forest Disease highlights the need to carry out various control strategies to reduce the tick population.
