This growth brings simultaneous burdens of sustaining a steady food supply; these include preventing losses from pests, dealing with increased human global travel, which in turn intensifies opportuni...
متن کاملImpact of insect-resistant transgenic rice on target insect pests and non-target arthropods in China
Progress on the research and development of insect-resistant transgenic rice, especially expressing insecticidal proteins from Bacillus thuringiensis (Bt), in China has been rapid in recent years. A number of insect-resistant transgenic rice lines/varieties have passed restricted and enlarged field testing, and several have been approved for productive testing since 2002 in China, although none...
متن کاملCurrent status and future perspectives on sunflower insect pests
While occasional insect pests of cultivated sunflowers may be managed by conventional or reducedrisk insecticides, the cumulative costs and risks of relying on insecticides to suppress perennial or severe pests (common in North America) call for exploration of broader pest management strategies. Recent research with the sunflower moth (Homoeosoma electellum [Pyralidae]) and banded sunflower...
