One example is the use of a bacteria called Bacillus thuringiensis on certain crops such as members of the cabbage family to help control Lepidopteran insects. The insects eat leaves which have the bacteria on them, and the bacteria have a protein which is toxic to the caterpillar, killing it.

How can the bacteria bacillus thuringiensis be used to control insects in crops since they produce protein crystals that are toxic to the digestive system of insects?
the bacteria bacillus thuringiensis produce protein crystals that are toxic to yhe digestive system of insects.How can these bacteria be used to control insects in crops?Apply the bacteria to growing plants. Bio technologists have devised a method to utilize Bacillus thuringens to prevent insects on crops. They insert the gene responsible for the protein crystals into the genome of the crop plants and culture the plants. The resultant plants produce the protein crystals by themselves because they contain the gene to do so. An example of the above method is Bt cotton. It is a high grade cotton plant which is naturally resistant to pests as it has been genetically engineered.

What is the definition of pesticides?
A pesticide is a chemical substance sprayed on crops to kill insects, pests and bacteria. The chemical agents called pesticides include herbicides (for weed control), insecticides, and fungicides. More than half the pesticides used in the United States are herbicides that control weeds. The United States Department of Agriculture (USDA) estimates indicate that 86 percent of U.S. agricultural land areas are treated with herbicides, 18 percent with insecticides, and 3 percent with fungicides. The amount of pesticide used on different crops also varies. For example, in the United States, about 67 percent of the insecticides used in agriculture are applied to two crops, cotton and corn; about 70 percent of the herbicides are applied to corn and soybeans, and most of the fungicides are applied to fruit and vegetable crops.They kill "pests".
