  • COMBINATION OF FOUR VIP AND CRY PROTEIN TOXINS FOR MANAGEMENT OF INSECT PESTS IN PLANTS
    Publication number: 20170298381
    Abstract: The subject invention includes methods and plants for controlling lepidopteran pests, especially soybean looper (Pseudoplusia includens) and velvet bean caterpillar (Anticarsia gemmatalis) insects. The plants, preferably soybean plants, comprise a combination of Cry1Ca, Cry1Ea, Cry2Aa, and Vip3Ab1 insecticidal proteins. Methods are described for using the plants to delay or prevent the development of resistance by insects.

  • CRY1D FOR CONTROLLING CORN EARWORM
    Publication number: 20150264940
    Abstract: 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.
