Bt-resistant Insects not Likely to Be a Problem for Maize Farmers

Dominic Reisig, an entomologist at North Carolina State University, received a phone call in 2013 from a farmer who was having trouble with fall armyworms (Spodoptera frugiperda), an insect pest that costs farmers in the southeastern United States tens of millions of dollars each year. This seemed odd because the farmer had planted Bt corn, […]

Genetically-Modified Honey Bees: A Key Technology for Honey Bee Research

By David O’Brochta A breakthrough in the efforts to genetically modify honey bees was recently reported by Christina Schulte and colleagues from Heinrich Heine University in the Proceedings of the National Academy of Sciences of the United States of America. Schulte et al. reported the creation of a honey bee containing a “foreign” gene — […]

Mosquitoes Modified to Create Only Male Offspring Could Help Eradicate Malaria

Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. In a study published in the journal Nature Communications, scientists from Imperial College London have tested a new genetic method that distorts the sex ratio of Anopheles gambiae mosquitoes, the main transmitters of the malaria parasite, […]

Beneficial Insects and Nematodes are not Harmed by Genetically-modified, Insect-resistant Plants

A large body of literature has shown that genetically-modified plants that produce proteins from the bacterium Bacillus thuringiensis (Bt) to protect themselves from insect pests have little to no effect on a wide range of nontarget insects. However, concerns about Bt crops still exist. Now two new studies using more exacting methods show that Bt […]

First African Study on Biodiversity in Genetically Modified Maize Finds Insects Abundant

Previous studies from China, Spain, and the United States on genetically modified (GM) rice, cotton, and maize have concluded that the biodiversity of insects and related arthropods in GM crop fields was essentially the same as that among conventional crops. Now a new study from South Africa shows similar results. The study is described in […]
