“…Thus, the T. bennetti record from Brazil can be attributed to an erroneous information compilation. In addition to Trinidad, T. bennetti also occurs in Colombia (Pinto 1999) and Venezuela, where it had been erroneously described as T. guariquensis [sic] Velásquez & Terán, junior synonym (Velásquez & Téran 2003).…”

Neotropical Entomology 32(2): 269-272 (2003) Identificação Molecular de Trichogramma cacoeciae Marchal (Hymenoptera: Trichogrammatidae):Um Novo Registro Para o Peru RESUMO -A história da taxonomia de Trichogramma teve um grande avanço com a descoberta dos caracteres morfológicos do macho. Entretanto, nem todas as espécies puderam ser facilmente identificadas. Em alguns casos, a identificação específica tornou-se impossível devido à ausência de insetos machos (condição das espécies telítocas infectadas por Wolbachia). Esse problema foi resolvido com a eliminação da bactéria por meio de tratamentos com uso de antibióticos e altas temperaturas. T. cacoeciae é a única espécie relatada até o momento cuja condição de telitoquia não é induzida por infeccção da bactéria Wolbachia, sendo necessário um novo método para identificação desta espécie. Resultados de alta confiabilidade têm sido obtidos na identificação específica de Trichogramma via sequenciamento da região ITS2 (Internal transcribed spacer 2). T. cacoeciae foi identificado com essa técnica e relatado pela primeira vez no Peru. A situação atual de T. cacoeciae na América do Sul é discutida.PALAVRAS-CHAVE: Insecta, parasitóide, telitoquia, DNA ribosomal ABSTRACT -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.
