1970's or 80's movie. Scenes take place in the desert and not really alot of action. A woman is either accidentially lost or abducted in the desert. It seems to me that there are killer scorpions involved. In one scene, she is tired and dehydrated and passes out on the ground, only to wake up later with a pain in her neck. She takes out a bobbipin that was holding her hair up and removes a giant (botfly like) larva from her neck, leaving a hole where it had burrowed in. The movie kinda reminds me of the old Kung Fu tv series from 1972-1975. I was a kid when I seen this movie and would like to see it again if I knew the name?
