摘要：

Females of the desert grassland scorpion P. utahensis were maintained in field enclosures and fed differing amounts of food. The number of young scorpions per female varied from 0-32. The mean weight of 2nd-instar young varied significantly among broods. The number of young, the size of the young, and total brood weight were not related to adult female size. None of the brood characteristics were significantly related to the amount of food eaten by the mother during the 11 mo. gestation, suggesting that foraging success is not an important proximate factor influencing fecundity in P. utahensis.
