| Un aspecto importante en el estudio de un parásito es conocer cómo varían sus parámetros biológicos en dependencia del hospedero sobre el cual se desarrolla. Se trabajó con dos grupos de hembras repletas de Anocentor nitens, 93 de ellas obtenidas de bovinos y 99 de equinos. Las adultas se pesaron en una balanza analítica y se dispusieron en subgrupos a dos temperaturas 26°C y 32°C y cuatro humedades relativas 100, 80, 75.5 y 70%, para un total de ocho combinaciones de temperatura y humedad relativa para las garrapatas de bovinos e igual número de combinaciones para las garrapatas de equinos; se colocaron de 10 a 12 hembras por variante. En todos los grupos se determinó la eficiencia de la puesta (peso de la puesta/ peso de la hembra repleta, en porcentaje)... |

| Multivariate statistical methods are relatively new tools for data analysis. They have a lot of applications in biological researches: nevertheless, for several reasons, they have not been widely employed in this subject yet. Recently, present authors published a paper applying multivariate statistics on non-parasitic phase of Anocentor nitens. In the present article Boophilus microplus has received a very similar statistic treatment. 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, 27, 30, 32, 34 and 36ºC and four relative humidity values, 100, 80, 75.5 and 70% over the cycle variables of B. microplus. According to the results, the best... |

| 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 34ºC 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.... |
