Insects have brains, though the insect brain doesn't play as important a role as human brains do.
Insects do not have a brain like you and me. Their behavior is driven purely by instinct. They do, however, possess a central nervous system. The insect "brain" consists of a mass of nerve cords called ganglia located in the head. The answer to your question is yes and no, depending on what your definition of "mind" may be.
They have a brain that comes pre-loaded with reactions & behaviors. They respond to stimulus as they have been programed. Weather you consider that thinking or not is an opinion.
