Development of Transgenic Cotton Plants -Effectiveness and Advances in Boll Weevil Control

摘要

Agriculture aims to achieve a sustainable economy while maintaining and improving crop yields worldwide. Several constraints limit crop production and, in this context, insect pests represent one of the most critical threats with adverse and damagingimpacts on agricultural production and market access.
