Predatory efficiency of the spider Thomisus sp. on Nezara viridula (L.) and Riptortus linearis (Fab.) adults.
Laboratory studies showed that the feeding rate of the predatory thomisid Thomisus sp. increased with an increase in available prey (individuals of Nezara viridula or Riptortus linearis). However, when 5 prey items were offered, the predatory efficiency decreased from 100 to 46.67, and 100 to 40%, respectively.
