Popis:	We describe effects of mating, female age, photoperiod, host storage temperature, and host availability on reproduction of Telenomus californicus Ashmead (Hym.: Scelionidae). Reproduction is arrhenotokous. Proportion of female progeny increases as the mating/maturation period without hosts is lengthened to 20 days. When successive batches of hosts are given to females, the total number of progeny and the proportion of females are greatest in the first batch. Females denied hosts for 4 weeks delayed oviposition until several weeks after hosts were provided; photoperiod did not influence their becoming reproductive. Development at 21°C takes 1–3 months; larval or pupal diapause were not observed. Reproduction is good in newly laid host eggs and in eggs stored at 5°C, but is poor in eggs killed by freezing.
