A MULTIVATIATE ANALYSIS OF Anocentor nitens (IXODOIDEA: IXODIDAE): NON-PARASITIC PHASE/[title]   [title language=es]ANÁLISIS MULTIVARIADO DE Anocentor nitens (IXODOIDEA: IXODIDAE): FASE NO PARASITARIA.

Multivariate statistical methods are useful tools complementary to classic univariate methods. In biology, they are used in several scenarios where data structure, classification and grouping are necessary. Nevertheless, it seems they have not been employed in the study of non-parasitic phase of ticks or any other arthropod. In this paper, the influence of different incubation conditions was studied in groups of 12-15 individuals in each of the 24 combinations of six temperatures 24, 26, 28, 30, 32, and 34^oC and four relative humidities 100, 80, 75.5 and 70% over the cycle variables of Anocentor nitens looking for establishing the most suitable environmental conditions to increase or decrease ticks performance and to apply these knowledges to zoogeography. According to the results, it seems that the best conditions to raise these ticks in laboratory are between 26-30^oC and 100% relative humidity.

Keywords : ticks; Ixodidae; Multivariate Analysis; non-parasitic phase.
