Study of the weight of eggs from six ixodid species from Brazil

Eggs from engorged females of six ixodidae species (Ixodes Iocatus, Amblyomma rotundatum, A. cajennense, Haemaphysalis leporis-palustris, Boophilus microplus, Dermacentor nitens) maintained in laboratory were counted to calculate the number and mean weight in Ig of eggs from each species. Phylogenetic considerations are discussed based on the results.
