2.1. Phoneutria nigriventer

A total of 509 spiders used in this study were collected from several natural regions of S˜ao Paulo state and Resende city (Rio de Janeiro) by the Biot´erio de Artropodes´, Instituto Butantan staff, or received at the reception of Venomous Animals of Instituto Butantan, which were brought by either the citizens or animal control services from different municipalities of S˜ao Paulo state. All spiders were quarantined for 7–14 days for observation of their behavior, their general health status, and the presence of ectoparasites, such as mites, and then, the feces samples were collected. During this period, the spiders were placed in glass containers with a humidified cotton ball and a cardboard substrate ( Fig. 1 ) maintained at a constant room temperature of 24 ◦ C (±0.5 ◦ C). They were fed with cockroaches ( Phoetalia palida or Nauphoeta cineria ) bred in captivity. To avoid the presence of parasites, the offered cockroaches were subjected to routine health control, including parasitological examination of feces, and the water used in the cotton balls was also tested to guarantee its quality.
