Another Step Forward in Genetic Engineering of Mosquitoes

mosquitoes cuticle-color genes disrupted

“Yellow, three-eyed, wingless mosquitoes” have made headlines this week, but the researchers at the University of California, Riverside, behind the news call the disruption of mosquitoes’ cuticle, wing, and eye development a “proof of concept” for a new advance in the genetic engineering method known as CRISPR/Cas9. The method may accelerate scientists’ work toward identifying the genes to target for disruption of mosquitoes’ ability to carry and transmit human diseases.

Odorant Receptor Gene in Codling Moth Also Affects Egg Production

A funny thing happened on the way to testing the CpomOR1 odorant receptor. Researchers at the USDA-Agricultural Research Service conducted an experiment on codling moth (Cydia pomonella) using the CRISPR/Cas9 gene-editing method to study the role played by a specific gene known as CpomOR1. The gene is highly expressed, or “switched on,” in the antennae […]

Ongoing NAS Study Examines Current Understanding of GE Crops

By Fred Gould Genetically engineered crops and their use in food are hot-button issues. People around the world have a wide range of questions and opinions about the agronomic, environmental, health, and socioeconomic, impacts of these crops. We entomologists have our own questions. How do genetically engineered crops fit into the spectrum of pest management […]
