Actor Jake Abel was the king of pranks on the set of The Host, revealing he once planted a plastic cockroach in his co-star Max Irons' trailer.

Abel frequently teamed up with Saoirse Ronan to terrorise Irons off-camera, and the actors even took their jokes on the road during the movie's publicity tour.

Ronan tells JustJared.com, "There was one prank that Jake pulled on Max, obviously, when we found out that Max was afraid of things with wings, so, like, moths and butterflies and any kinds of insects. He found this little plastic sort of cockroach thing that we put in his microwave that he would use everyday to heat up his lunch. And just watched the trailer waiting. And eventually he came, like ran out of the trailer freaking out!"

But Abel's antics didn't stop there. Irons adds, "He's a little s**t. He loves playing pranks... He decided to tell the world that I'm terrified of insects. We had a signing the other day with 1,000 people, lots of whom threw plastic insects, or in some cases real insects, onto the table."
