UNASSIGNED: Unlike the application of @entity25551 (Bti) for the control of larval mosquitoes, studies of its effects on adults, for its possible use in attractive @entity137 , have resulted in conflicting results. Five species have shown a decrease in adult survival due to Bti ingestion, whereas adults of Anopheles arabiensis have not. We sought to determine if ingestion of Bti by adults of @entity313 , a sibling species of An. arabiensis, increases their mortality. Laboratory-reared adults were provided continuously from emergence with water only, a @entity969 solution, or a Bti suspension in @entity969 solution. After 3 days, the Bti suspension was replaced with untainted @entity969 solution. The mosquitoes with only water were all dead by day 3. The survivorships of those in the @entity969 and @entity969 -Bti treatments were insignificantly different, both with an LT50 (Lethal Time, time until 50% of individuals died) of 25 days. The results support the conclusion that adult survivorship of An. gambiae-complex members is unaffected by the ingestion of Bti in sugar meals.
