Abstract

Crocidosema aporema (Walsingham 1914) has historically been the main bud borer species in soybean in Brazil; however, a recent study reported that this species is not C. aporema but an undescribed species. In recent seasons, injury by Crocidosema sp. has been reported in soybean expressing the Bacillus thuringiensis Berliner (Bt) toxin Cry1Ac. In this study, we investigated the genetic basis of Cry1Ac resistance and assessed the fitness costs of resistance in a field-derived Cry1Ac-resistant Crocidosema sp. strain selected through an F₂ screen.
