It is genetically modified cotton as a result of technological development in the nineties and who had an implicit impact on reducing production costs and thereby increase productivity of the early adopters of this technology. Cotton axis types of genetically engineered to have cotton Bt this type of cotton containing one or more of the genes derived from the bacterium Bacillus thuringienis, these bacteria are found in soil and its production of a protein feature crystal-like him the ability to kill a group of insects that are found in soil and some neighborhoods other, so the cotton, which introduced him these genes become capable of producing the active protein in the killing of some of the more insect larvae harm to cotton, such as tobacco larvae, budworms and bollworms as the total cost of the control of these insects and losses that occur on cotton production in excess $ 300 million a year.
Bt cotton and can indirectly reduce general abundance of some beneficial insects
