PATHOLOGY

Detailed explanation-1: -The protein is very selective, generally not harming insects in other orders (such as beetles, flies, bees and wasps). For this reason, GMOs that have the Bt gene are compatible with biological control programs because they harm insect predators and parasitoids much less than broad-spectrum insecticides.

Detailed explanation-2: -Corn is the most commonly grown crop in the United States, and most of it is GMO. Most GMO corn is created to resist insect pests or tolerate herbicides. Bacillus thuringiensis (Bt) corn is a GMO corn that produces proteins that are toxic to certain insect pests but not to humans, pets, livestock, or other animals.

Detailed explanation-3: -Genetic engineering facilitates development of insect resistant crops by expressing bacterial d-endotoxins and vegetative insecticidal proteins and other plant genes like lectins, protease inhibitors, etc.

Detailed explanation-4: -Insect-resistant transgenic crops were first commercialized in the mid-1990s with the introduction of GM corn (maize), potato and cotton plants expressing genes encoding the entomocidal -endotoxin from Bacillus thuringiensis (Bt; also known as Cry proteins).
