Encapsulation of Beauveria bassiana conidia as a new strategy for the biological control of Aedes aegypti larvae.

ABSTRACT: The virulence of encapsulated fungal conidia against Aedes aegypti larvae was investigated. Molecular studies confirmed that the fungal isolate used here was Beauveria bassiana. Different conidial concentrations were tested. A concentration of 1 × 10⁸ conidia mL^- 1 was the most effective, resulting in 7% larval survival after 7 days. Next, alginate capsules (0.65%) containing conidia were prepared with different densities of calcium chloride (0.01 M, 0.009 M, and 0.008 M CaCl₂) and tested against larvae. Furthermore, groups of capsules were prepared with bird diet to act as an attractant. All capsule densities tested reduced larval survival (ranging from 22 to 67%). However, capsules with 0.008 M CaCl₂ were the most effective. Furthermore, fungus-only capsules were mo
