Ancient olfaction protein is shared by many bugs, offering new pest control target

...though many odorant-receptor proteins appear to be species specific, there is a high degree of evolutionary conservation of the Or83b coding sequence among the fruit fly, the medfly (a citrus pest), the corn earworm moth (which damages corn and tobacco), and Anopheles gambiae, the malaria mosquito. When the ...
