摘要

In the present work, we aimed to evaluate: 1) the influence of the Cry1Ac protein expressed by the genetically modified cotton variety (Bt) NuOpal, on the biological parameters of a non-target pest,?Aphis gossypii, reared under laboratory conditions; 2) the influence of plant age on aphid development. Cotton cultivars were grown following technical advice. In the laboratory, the aphids were separated into plastic containers including a cotton sheet, which was changed daily with the help of a moist cotton cloth. Observations were carried out daily, and the duration of the immature and adult stages, and offspring number, were recorded.?Our results show thatregardless of the?differences?in the duration?of each?instar,?cultivars?Bt?and non-Bt?and the different?ages of the plant?to?Bt,?no differences were seen?in?the?total duration?of these phases. It was?only?during the reproductive period?that?differences?were observed?among genotypes for?120 days.?Regarding the number?of offspring?and longevity?total,?there were differences?between the different?ages?of the?Bt?treatment.
