The aim is to assess the insecticidal efficacy and environmental adaptability of Bacillus thuringiensis subsp. israelensis strains against Aedes aegypti larvae.
Controlled laboratory assays with Bacillus thuringiensis strains 33, 87/1, and 7-1/3 to determine larvicidal activity.
Proteomic profiling using SDS-PAGE and Western blotting to analyze δ-endotoxin complex synthesis.
Field applications across different biotopes in Ukraine to assess larval suppression rates.
Laboratory assays showed LC50 values of 1.15–1.48 µL/L with 95-96% cumulative mortality in 48 hours.
Field applications achieved 95–100% larval suppression rates within 48 hours at application rates of 0.25–1.0 mL/m2.
Proteomic analysis confirmed the presence of Cry4Aa, Cry4Ba, Cry11Aa, and Cyt1Aa in Bti cultures.
