| Trombiculidae | A family of mites whose larvae (redbugs, rougets, harvest mites, scrub mites, or chiggers) are parasitic on vertebrates and whose nymphs and adults are bright red and free-living, living on insect eggs or minute organisms in the soil. The six-legged larvae are barely visible red or orange parasites that attach to the skin for a few days to a month, producing an exceedingly irritating reaction. In the Orient, trombiculid chiggers of the genus Leptotrombidium transmit tsutsugamushi disease caused by Rickettsia tsutsugamushi, which is transovarially transmitted in these mites. (05 Mar 2000) |
