Comparison of two commercial formulations of Bacillus thuringiensis var. israelensis for the control of Anopheles aquasalis (Diptera: Culicidae) at three salt concentrations.

Anopheles aquasalis larvae are salt water tolerant, preferring concentrations between 10 and 20 parts per thousand (ppt). The larvicidal efficacy of two formulations of Bacillus thuringiensis var. israelensis (Vectobac-12AS and Bactivec), was investigated against An.

Oviposition preference and egg eclosion in different salt concentrations in the coastal malaria vector Anopheles aquasalis Curry.

Anopheles aquasalis is the main malaria vector in Sucre State, Venezuela. The larvae of this species are saltwater tolerant. The effects of different concentrations of salt on oviposition preference and egg survival were studied under laboratory conditions.
