Some of our farmers use our yellow sticky papers to catch Tuta absoluta. 

Can you see the Tuta absoluta moths flying?
Normally this pest is not attracted to just a yellow paper, however we are using a pheromone inside the yellow sticky paper. The advantage is that you will catch white flies as well as Tuta absoluta with the same trap. This video was sent to us by one of our farmers in Taita taveta region.
