Resumo: | Discovery of male morphological characters for species identification was a great improvement in Trichogramma systematic. However, not all species could be easily identified. In some cases, the lack of males (thelytokous status of species that carry the Wolbachia symbiont) made Trichogramma identification impossible. This problem was solved via antibiotic and heating treatments for elimination of the bacteria and allowing the production of males. The only Trichogramma species reported in which thelytoky is not induced by bacterial infection is T. cacoeciae, so here another means of species identification is needed. This species was identified based on the ITS2 (Internal transcribed spacer 2) sequence, a modern technique that has been proved useful in providing a reliable identification of Trichogramma species. Here we report the first occurrence of T. cacoeciae in Peru and we discuss its distribution in South America. |
