Mosquito Eggs (IMAGE) University of Arizona Caption Eggs laid by mosquitoes treated with RNAi against the EOF-1 protein (right) and a control (left) display striking differences in their shells: Instead of a surface covered in regular bumps (each about 15 times smaller than the diameter of a human hair), EOF-1 deficient mosquitoes lay eggs in which this regular structure is disrupted. Lower images are magnifications of the egg shell structure. Credit Jun Isoe Usage Restrictions This visual may only be used in conjunction with reporting on or posting of this news release.
