ABSRACT - [ Total Page(s): 1 ]A major challenge for achieving successful mosquito control is overcoming insecticide resistance. Bacillus thuringiensis which is one of the most effective biolarvacide for control of species of mosquitoes and monitoring of larval susceptibility is essential to avoid resistance development. Mosquito larvacidal activity of Bacillus thuringiensis was assessed by isolating them from ecologically different soil habitats in and around Enugu metropolis. The isolate organisms were confirmed as Bacillus thuringiensis based on biochemical characterization and microscopic observation. The larvacidal act

CHAPTER ONE - [ Total Page(s): 3 ]OTHER PATHOGENIC FACTORS OF BACILLUS THURINGIENSISAt the period of the active growth cycle, the strains of Bacillus thuringiensis produce extracellular compounds; this compound might yield to virulence. These extracellular compounds include proteases, chitinases phospholipases, and vegetative conseticidal protein (Zhang et al. 1993; Sohneff et al. 1998).Bacillus thuringrensis also produces antibiotics compounds having antifungal activity (stab et al. 1994). However the crystal toxins are more effective then these extracellular compounds and allow the development of the bacteria ... Continue Reading
