Fj. Zara et Fh. Caetano, Number of larval instars of the ant Pachycondyla (=Neoponera) villosa (Formicidae : Ponerinae) determined by the rule of Dyar., SOCIOBIOLOG, 37(3B), 2001, pp. 679-686
In this work we present the number of larval instars in the Ponerinae ant P
achycondyla (=Neoponera) villosa. The analysis of maximal head capsule widt
h measurement of 147 larvae was made. Four larval instars were measured: Is
t instar the cephalic capsule varied from 0.18mm to 0.22mm; 2nd instar from
0.23mm to 0.27mm; 3rd instar from 0.30mm to 0.33mm and the 4th instar vari
ed from 0.35mm to 0.38mm. The mean growth rate was 1.2375 according to the
rule of Dyar. We also reviewed the number of larval instars for 35 ant spec
ies.
