Mites and insects showed different behaviour in relation to these factors. Only the fleas and lice exhibit significant association between the rodents&amp;rsquo; infestation and the seasonal period, or between the infestation and the rodents&amp;rsquo; sex or else a variation of the distribution by the three main areas of capture. The fleas showed the highest indices of infestation in the warm-rainy season (October to March) while the infestation by the lice was more prevalent in the dry-cool season. The climatic factors most related with the hosts&amp;rsquo; infestation were, in decreasing order, rainfall, temperature and relative humidity. Fleas and lice preferentially infested male rodents, being infestation by X. cheopis highly significant.&lt;/p&gt;
