Resumo. Anthocorid bugs presents attributes that make them promising agents of biological control. Several species can be reared in the laboratory for later release in the field and in greenhouses, and some of them also exhibit zoo-phytophagous feeding behavior, which favors maintenance in the environment, as occurs with Xylocoris afer (Reuter, 1884) and Xylocoris sordidus (Reuter, 1871). This work aimed to describe a method that optimize the rearing and multiplication in laboratory of Xylocoris spp. and their alternative prey Corcyra cephalonica (Stainton, 1866). The method was adapted replacing inflorescences of Bidens pilosa L., by rolls of hydrophilic cotton inserted in glass jars of 25,0 mL filled with water to maintain the humidity, which is essential to the embryonic development of the insect. The adaptations made to the rearing methods of these predators and the alternative prey have made the breeding of mainly predators more practical and effective.
