Abstract
Pests represent a major threat to food crops and human health, and therefore have to be combated in several ways, including chemical methods using pesticides. However, researchers demonstrated that these molecules are dangerous for the farmers, consumers and the environment in general. For this reason, scientists permanently searched environment friendly alternatives such as the use of the bacterium Bacillus thuringiensis classified as one of the best insect pathogens. This microorganism is known by its ability to produce two types of insecticidal proteins, Vegetative insecticidal proteins (Vip) and d-endotoxins produced during vegetative and sporulation stages of growth, respectively. This paper will discuss the main approaches used in the pest management control including chemical, physicomechanical and biological control methods. The review is also intended to demonstrate the efficiency of biopesticides in the control of pests and especially B. thuringiensis and its proteins worldwide known as eco-friendly insecticide that able the improvement of agriculture crops productivity.
