Five hundred thirty parasitoids were recovered from 99 sample sites. <em>Encarsia</em> spp. represented over 90% of the total samples profiled, whereas <em>Eretmocerus</em> spp. represented only 9.5%. <em>Eretmocerus hayati</em>, from Pakistan, represented 56% of the total of that genus, followed by <em>Er. mundus</em> from Spain (38%). An <em>Encarsia sophia</em> species from Pakistan was the most abundant, representing 29.6% of the total number of specimens from that group and 26.8% of the total number of specimens recovered during the study. Five unidentified, and possibly undescribed, species from Puerto Rico were detected during the study. Two of the local species represent about 23% of the total number of specimens collected.</p><p> </p> ER -
