摘要
(US20100029725) Insect refuge strategies are described for the management of insect resistance development.  The present invention relates generally to the control of pests that cause damage to crop plants, and in particular to corn plants, by their feeding activities directed to root damage, and more particularly to the control of such plant pests by exposing target pests to seeds or mixtures of seeds having multiple different modes of action.  The first one or more transgenes and the second one or more transgenes are each, respectively, insecticidal to the same target insect but have different modes of action, and bind either semi-competitively or non-competitively to different binding sites in the target pest.  In addition, the treatment of such seed with a chemical or peptide-associated pesticide prior to planting the seed is also disclosed.
