Vásárhelyi, T.: Investigations on the allometric growth of Aradus species (Heteroptera, Aradidae)

Allometric growth of antennái joints Since (he shape of the antenna and the relative length of the antennái joints are inavitably frequently used in identification of adult Aradidae, attempts were made to prove the suitability of the allometric growth of the antennái joints in identifying fifth instar larvae and also in distinguishing the different developmental stadia of Aradus species. The ratio of the joints to each other, to the total length of the antenna (Figs. 4-7, Table 2) and to head width (Table 1) were investigated. Figs. 4-6 constructed as the previous ones show obvious differences in growth trends (the moderately changing joint 1 was not figured). The length of antennái joints 2, 3 and 4, respectively, was plotted against head width in two species both
