These plots relate tick total abundance and tick stage abundance of both dry and wet seasons, (as an equivalent of observed use of each habitat resources) (red bar ; frequency on the y’-axis on the right) and the potential or available area of the habitat that A. mixtum might use (blue bar ; frequency on the y-axis on the left) at the Matepanano farm. Thus, the higher the red bar and the lower the blue bar, the greater the habitat preference. When the red bar barely exceeds or equals the blue bar, the relationship corresponds to habitat usage. When the blue bar far surpasses the red bar, there is avoidance of such a habitat (see tables 35). (A). Dry season. (A1) The mathematical index points out that A. mixtum uses all four habitats. In addition, A. mixtum population (stage independent) uses three habitats and shows preference for Star Grass Paddock and King Grass Crop, while it avoids the Riparian Forest habitat. (A2) Adults of A. mixtum prefer King Grass Crop, while they use the remainder habitats. (A3) Nymphs of A. mixtum prefer King Grass Crop and Cocoa Crop; they use Star Grass Paddock, but they avoid the Riparian Forest habitat. (A4) Larvae of A. mixtum prefers three habitats (King Grass Crop, Cocoa Crop, and Star Grass Paddock), while they only use the Riparian Forest habitat. (B). Wet season. (B1) A. mixtum population (stage independent) prefers King Grass Crop and Star Grass Paddock; it uses Cocoa Crop and avoids Riparian Forest. (B2) Adults of A. mixtum prefer King Grass Crop and Cacao Crop, while they use Star Grass Paddock and Riparian Forest. (B3) Nymphs of A. mixtum uses Cocoa Crop; they prefer Star Grass Paddock and King Grass Crop, and they avoid the Riparian Forest habitat. (B4) Larvae of A. mixtum only uses two out of four habitats, preferring the Star Grass Paddock, and using the King Grass Crop.
