Scheloribates Jaevigatus (Koch) was able to  develop and reproduce when fed  on mixture of free-living nematod, Eudiplogaster phlagellicaudatus (Andrassy) and potato. Temperature had a significant effect on duration of the life cycle and all life span of this species. As temperature changed between 25 and 30°C, the incubation period decreased. Both male and female immature stages decreased when temperature increased between 25 and 30°C. Life cycle of male reached adulthood in a shorter period than that of female. This period decreased from 24.67 ± 0.26 to 21.25 ± 0.53 days for male and from 28.01 ± 0.66 to 23.16 ± 0.98 days for female at 25 and 30°C, respectively. Temperature also negatively affected the adult female longevity and fecundity. It was found that the greatest average number of eggs deposited by female was 36.88 ± 2.13 at 25°C; this decreased to 29.63 ± 2.55 at 30°C.
