Androctonus australis hector insect toxin be reduced 44-98% by creating transgenic cotton crops which express the "AaHIT" gene. Another example in which AaHIT can be used as an insecticide is via baculoviruses. Baculoviruses are themselves insect-specific viruses; they can be potentiated if they express the "AaHIT" gene. The potentiated viruses kill the insects faster, resulting in less damage to the crops. Androctonus australis hector insect toxin "Androctonus australis hector" insect toxin also known as AaHIT is a scorpion toxin which affects voltage-gated sodium channels. Four different insect toxins, namely AaHIT1, AaHIT2, AaHIT4 and AaHIT5, can be distinguished. It targets insects, except AaHIT4, which is also
