Filhotes de escorpião T. serrulatus: nascimento e desenvolvimento em cativeiro

Abstract

Most scorpions are ovoviviparous, ending their full development on the back of their mother. The development juvenile yellow scorpion Tityus serrulatus Lutz & Melo, 1922 was analyzed under captivity conditions during five months in the Butantan Institute Arthropod vivarium to better understand its growth. In the course of the experiment, 164 females were given, which granted 1,857 newborns, showing how this species of scorpion can multiply easily under laboratory conditions. Females were screened based on their enclosure identification and the number of extractions suffered, showing that they were not affected by extractions in relation to reproduction. The time stipulated for juvenile dispersal was up to 15 days. It can be noticed that the group that did not undergo any extraction, the newborn spontaneously dispersed something that did not happen to the other groups with one or more extraction, having an average of 4.95% of forced dispersion. We also noticed that during the work performed, the weight increased three times more than the initial weight of the puppies, and the growth was 1.5mm. For its better development was verified that the feeding three times in the week has a notorious relevance.
