Resumo: | This research was carried out to study some aspects of the biology and behavior of Nesolynx sp. (Hymenoptera, Eulophidae), a pupal parasite of Psorocampa denticulata (Lepidoptera, Notodontidae) a defoliating caterpillar of Eucalyptus spp. in Brazil. The adults emerge from the host pupa through a circular hole on Its dorsal region. Mating occurs righ after the emergence and the longevity of adults was two days for the males and four days for the females. Regarding to the host species Diatraea saccharalis showed a number of adults significantly greater than Galleria mellonella and the increasing temperature from 21±1 °C to 26±1°C caused a significative increasing in the number of emerged adults in both host species. The emergence of adults increased proportionally to the period of exposition to the host up to 3.50 days; after that, a considerable decrease in the emergence was observed. The parasitoid showed parthenogenetic reproduction therefore the average number of emerged males was significantly greater than the number of females. The sex ratio was similar for the insects emerged from virgin or mated females (0,96) and the life cycle lenght was around 18.34 days for both conditions.
