The efficacy and persistence of four commercial formulations of against early fourth instar larvae of Anopheles aquasalis, were evaluated in laboratory conditions. The formulations were: Vectobac-G (0,2%, Abbott), Vectobac-AS (0.6%, Abbott), Teknar (1,6%,Zéneca) and an experimental microencapsulated formulation M-Bti (0,1%, J. Margalit, Harvard Univ.). The microencapsulated formulation required the smallest LC50 and LC95 (0.006 and 0.05 ppm, respectively); Vectobac-G required the largest LC50 and LC95 for fourth instar larvae of An. aquasalis (0.48 ppm and 4.8 ppm, respectively). However, LT50 was shortest for Vectobac-G (3.7 h) and the longest for M-Bti (6.7 h). Increment of larval density and larval age reduced the M-Bti efficacy. Tekn...
