Researchers Kun Yan Zhu and Jian-Rong Gao found that greenbugs with resistance develop a higher rate of the acetylcholinesterase enzyme, requiring more insecticide to kill. This breakthrough may lead to better pest control methods by monitoring resistance in individual fields.
Genetic modified organism (GMO) crops can benefit from a 'refugia strategy' that preserves susceptible insect genes. This approach aims to counteract potential insect resistance by allowing certain pests to survive and breed in GMO-free areas.
Researchers at Purdue University developed a method to use pesticides in a precise way to stop genetic resistance from arising. Using multiple pesticides together can delay resistance for decades, potentially reducing costs and social impacts.
A Clemson-led team led by Linda J. Gahan has made a breakthrough in tracking genetically the tobacco budworm's efforts to become resistant to biotechnological pest controls. The discovery opens the door for monitoring resistance mechanisms and management strategies in insect pests.
Scientists have discovered the genetic and molecular means by which roundworms develop resistance to Bt toxins, which are safe to humans but threaten long-term effectiveness. The researchers identified a galactosyltransferase enzyme as key to toxin recognition, enabling the development of strategies to delay or circumvent resistance.
Researchers have identified a gene that confers high levels of resistance in the tobacco budworm moth to genetically engineered crops with built-in insecticides. This discovery will enable farmers and government officials to take early steps to prevent uncontrollable outbreaks by detecting the early signs of pests evolving resistance.
Researchers found that field refuges made of non-Bt plants can prevent insects from developing resistance to Bt-engineered crops. The study demonstrated the importance of carefully managing insects within these refuges to ensure their effectiveness.
Researchers at Kansas State University conducted a genetic study on corn borer resistance to Bt toxins, finding that the European corn borer's resistance appears to be inherited as an incompletely dominant trait. The team emphasizes the importance of developing effective resistance management plans to mitigate potential losses.
