Solution

The trigger for activation of toxin of bacillus thuringlensis is alkaline PH of gat.

Explanation:

Bt toxins are originally inactive protoxins, but due to the alkaline PH of the gat, which solubilizes the crystals, they become active after consumption by the insect. As a result, a high PH value is necessary to make Bt toxins active. When temperatures are high and the PH is acidic, Bt toxins remain insoluble and inactive.
