نویسندگان
چکیده
Parasitoides do gênero Trichogramma são utilizados em todo o mundo para manejo de pragas. A capacidade dispersão desses insetos cultivos determina número pontos necessários liberação que haja resultados satisfatórios quanto ao parasitismo e consequentemente, da praga. Para determinação T. pretiosum couve repolho, foram demarcadas áreas 26 x m, colocadas cartelas contendo ovos A. kuehniella distribuídas forma concêntricas equidistantes. No centro cada área liberados 100 mil parasitoides foi permitido por 24 horas. O delineamento experimental utilizado blocos casualizados, com cinco tratamentos (distância) quatro repetições. distância média dispersada 6,27 metros 6,07 enquanto 81,23 na cultura 79,03 no cultivo sendo possível determinar hectare 123 126 repolho.

This work aims to evaluate the interspecific interaction between Trichogramma pretiosum and Telenomus remus, two biological control agents of fall armyworm (Spodoptera frugiperda) eggs. Eggs of Spodoptera frugiperda previously parasitized by Telenomus remus were offered to Trichogramma pretiosum, and those parasitized by Trichogramma pretiosum were offered to Telenomus remus. The previously par...

In this study we assessed the relationship between the laboratory and field performance of different isofemale lines of Trichogramma pretiosum Riley. In comparative assays, we used three rare mitochondrial haplotypes as genetic markers of the isofemale lines, and by introgressing these mitochondrial haplotypes into each of 15 genetically different nuclear lines, also tested the assumption that ...
