From 60-80% of 3000-5000 females of T. nigrovittatus Macquart taken on 5 occasions at West Galveston Bay, Texas, fed on beef blood through prophylactics when the blood was held at .apprx. 100.degree. F and ATP was added at 10-3 to 10-4 M. Survivorship, fecundity and fertility were very high in gonotrophically young females taken from this population in late June and early July. Approximately 30,000 emergent T. nigrovittatus larvae were obtained from eggs held in the laboratory under ambient conditions (75.degree. F .+-. 5 and 65% .+-. 5 relative humidity). Larvae reared on stable fly maggots in a 2:1 peat-sand mixture matured in 6-8 wk but then entered diapause and emerged in April of the following year. Recovery of up to 8 adults/800 cc of substratum suggested that cannabalism did not deter rearing specimens en masse. No evidence of mating was observed.
