Insect-resistant varieties are an ideal way to control or suppress crop pests. Insensitive varieties used in the production of low cost, no pesticide residue on the food environment, nor polluting plants and other beneficial insects, only the balance between the pests and their natural enemies slightly disturbed, and with the physical, chemical, Cultivation and other methods of pest control harmonious fit, the plant’s insect resistance only when the pest infestation plants only show results.
