Effect of Bacillus thuringiensis var. israelensis (H-14) on Culex, Aedes and Anopheles larvae (Cotonou; Benin)

摘要

The use of insect-specific toxins from Bacillus thuringiensis var. israelensis is forming an increasingly important component of biological control strategies that are either being implemented or planned for use in mosquito control. In terms of morbidity and mortality caused by vector-borne diseases, mosquitoes are the most dangerous animals confronting mankind. They threaten more than 2 billion people and have substantially influenced the development of mankind, not only socio-economically but also politically. In this study, the use of Bacillus thuringiensis var. israelensis crystals for controlling insect’s larvae was carried out at laboratory scale. Three species of insects were tested. The operational parameters for the most efficient use and monitoring of Bacillus thuringiensis var. israelensis toxins against insect’s larvae in the laboratory were discussed.
