I don't know how they make them, but keep in mind crickets can't feel pain, and are cold blooded (so can't really feel temperature either).

They can't feel pain? You have a citation for that claim?

You can use google just as well as I can. Search for "insect feel pain".

They don't have the necessary nerves to carry pain signals.

As an example, if you cut off part of the leg of an ant it keeps walking like normal, and doesn't show any indication that it felt anything. (They used this with a cool experiment that showed ants count steps when navigating - the shorter legs meant they walked a shorter distance, but kept the same number of steps.)

I did research this topic and recent studies show insects DO feel pain, and unlike you I have a citation to back it up: http://www.sciencedirect.com/science/article/pii/S0092867403...

No, this shows the larva are able to sense heat, not pain.

Read the actual paper, not the title.
