cry1d para controle da lagarta-da-espiga-do-milho. a presente invenção refere-se em parte à surpreendente descoberta de que cry1da é ativa contra a lagarta-da-espiga-do-milho (cew), helicoverpa zea (boddie). encontram-se descritos métodos para uso de cry1da em plantas transgênicas para prevenir danos sérios à cultura. bioensaios de folhas e barba de milho usando milho transgênico expressando a região de toxina de núcleo de comprimento integral ou cry1da quimérica demonstraram proteção satisfatória de insetos contra danos causados por larvas de cew. The subject invention relates in part to the surprising discovery that Cry1Da is active against corn earworm (CEW),Helicoverpa zea(Boddie). Methods for using Cry1Da in transgenic plants to prevent serious crop damage is described. Leaf and silk bioassays using transgenic maize expressing full length, core toxin region or chimeric Cry1Da demonstrated good insect protection against CEW larvae damage.
