In what regards longevity and parasitic capacity, a significant difference (p<0,05) was found between the population of São Jorge and the other two. A significant difference was also observed between the population of São Miguel and the others, when comparing development time. Concerning daily parasitism. was higher relevant in the first four weeks for any of the studied populations, that is 80.15, 78.38 and 72.42 % for A, B and C, although, 50% parasitism was attained in the first week. Comparing the emergence rates it was observed that they presented similar mean values, that is 95.41, 91.70 and 90.48 %, for A, B and C populations.engParasitismoTricogramaAçoresParasitic CapacityTrichogramma sp.Azoresjournal article
