Locusts have a reputation of biblical proportions – when swarming they have been known to consume entire crops and devour grass for livestock. In doing so, they can destroy livelihoods for farmers and ...

Duke University biologists have evolved a complex trait in the laboratory -- using the pressure of selection to induce tobacco hornworms to evolve the dual trait of turning black or green depending on ...

BLOOMINGTON, Ind. -- An Indiana University biologist has been awarded $750,000 to identify the genetic mechanism that makes up a "switch" allowing some genetically identical species to develop ...

Scientists investigate how genes in some insects can influence one another to change their expression depending on environmental conditions. A grasshopper hatched in a crowded environment may look and ...
