Resistance of Spodoptera littoralis to biopesticides

The development of synthetic pesticides during 1940`s, in combination with improvement in chemical application technology, dramatically increased the potential for agricultural pest control. It did take long before people began to see naturally controlled by predators and parasites began to cause significant damage. They also become resistance to chemicals. For that the aim of this work was to search a new isolation of bacteria for solution or delayed the appearance of resistance problem.
