Of the three species, T. The relationship between social life aggregation of lizards and damage caused by parasites has also been explored.

In the ventral view of the idiosoma, Claparede’s organs are between the coxae of the first and second pairs of legs. Instead, they feed on haemolymph or digested host tissue. The use of the mite pockets and skin folds by the larvae of E. Their main goal was to test the existence of possible differences in the pattern of parasitism related to seasonal environmental variations, although alreddugesi hypothesis has not been confirmed.

Larval population densities along a forest edge were greatest in areas of high relative humidity, moderate temperature, low incident sunlight, and increasing substrate vegetation.

They settle in the fold and begin feeding. This is is how they sense vertebrates approaching. After fertilization, the female Eutrombicula alfreddugesi lays eggs after about two weeks. In other words, Central and South America. Eutrombicula alfreddugesi has a few means of perceiving its environment. This protonymph develops inside the cuticle of the engorged larva.



It has been hypothesized that these “mite pockets” evolved to reduce damage to the lizards by concentrating mite populations. The gnathosoma consists of chellicerae and pedipalps. These variable results point to the need of further work on this subject. Arthropod and filarioid parasites associated with wild rodents in the northeast marshes of Eutrombcula Aires, Argentina.

They are found primarily in soil, surface litter, and decomposing tree trunks.
