description <p id="para1">Eggs of <italic>Anagasta kuehniella</italic> (Zeller 1879) are widely used for mass rearing of <italic>Trichogramma</italic> spp. and other parasitoids and predators, largely commercialized in many countries. The aim of this study is to evaluate the effect of carbon dioxide (CO<sub>2</sub>) originated from larval metabolism on the biological parameters of <italic>A. kuehniella</italic>. For that purpose, we assess the production of carbon dioxide (CO<sub>2</sub>) per rearing tray of <italic>A. kuehniella</italic> and the effect of CO<sub>2</sub> on the viability of egg-to-adult period and oviposition of <italic>A. kuehniella</italic>. Results allow to estimate that a rearing tray, containing 10,000 larvae between the 4<sup>th</sup> and 5<sup>th</sup> instars, produces an average of 30.67 mL of CO<sub>2</sub> per hour. The highest egg production of <italic>A. kuehniella</italic> was obtained when the larvae were kept in rooms with lower concentration of CO<sub>2</sub> (1,200 parts per million - ppm), producing 23% more eggs than in rooms with higher CO<sub>2</sub> concentrations. In rooms with high density of trays (70 trays/room), CO<sub>2</sub> concentration exceeded 4,400 ppm. The viability of the egg-to-adult period was not influenced by carbon dioxide.</p><br><p id="para2">Ovos de <italic>Anagasta kuehniella</italic> (Zeller, 1879) s&#227;o muito utilizados para a cria&#231;&#227;o massal de <italic>Trichogramma</italic> spp. e de outros parasit&#243;ides e predadores, sendo comercializados em muitos pa&#237;ses.
