Resumo: The objective of this work was to evaluate the influence of the embryonic development of eggs from the P. xylostella host on Trichogramma exiguum females of different ages. Fifty females – either just-emerged or 24, 48, 72 and 96 hours after emergence of this parasitoid were divided into five groups. Each female was offered a recipient with 30 P. xylostella eggs, which were 1-, 2- and 3-days-old. The greatest rates of parasitism were observed on eggs with 3 days of embryonic development, with exception of those 72-hours-old. Viability was not influenced by parasitoid age or host embryonic stage. Sex ratio was similar in all three embryonic host stages for T. exiguum females that were 24-, 48- and 72-hours-old. While evaluating parasitoid progeny obtained from eggs with 3, 2 and 1 days of embryonic development, it was verified that the highest values of longevity were obtained when the females used were just-emerged, or 48- and 72-hours-old, respectively. These results indicate the importance of the age of the parasitoid, as well as the host embryonic development period, in order to maintain quality of T. exiguum at laboratory conditions, in mass culture, as well as in field releases for biological pest control.

Para tanto, cinquenta fêmeas recém-emergidas ou com 24, 48, 72, e 96 horas após a emergência deste parasitóide foram divididas em cinco lotes. Para cada fêmea, foi oferecida uma cartela, contendo 30 ovos de P. xylostella com um, dois e três dias de idade. As maiores taxas de parasitismo foram observadas em ovos de três dias de desenvolvimento embrionário, independente da idade do parasitóide, com exceção daqueles com 72 horas de idade. A viabilidade não foi influenciada pela idade do parasitóide e nem pela fase embrionária do hospedeiro. A razão sexual foi semelhante nas três fases embrionárias do hospedeiro para fêmeas de T. exiguum com 24, 48 e 72 horas de idade. Ao avaliar os descendentes do parasitóide provenientes de ovos com três, dois e um dia de desenvolvimento embrionário, verificou-se que os maiores valores de longevidade foram obtidos quando foram usadas fêmeas recém-emergidas ou com 48 e 72 horas de vida, respectivamente. Estes resultados indicam a importância da idade do parasitóide, bem como o perído de desenvolvimento embrionário do hospedeiro para manter a qualidade de T. exiguum em laboratório, em uma criação massal, e também nas liberações de campo para o controle biológico de pragas.Universidade Estadual De Maringá2007-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/52210.4025/actascibiolsci.v29i2.522Acta Scientiarum.
