Thripline and Trapline +

Thripline is a pheromone specific to Frankliniella occidentalis which is an aggregation pheromone that will attract adults to the trap.  Addition to normal yellow traps in the form of a lure/ rubber septum which is attached to the trap increases the attractiveness of the traps to WFT.  Addition to a  yellow trap will make it just as effective as a blue trap.

Trapline + is a trap where the pheromone is incorporated into the glue during manufacture.

The pheromone can also be used as a spraying aid, causing the adults to emerge from the crop where they are hide to make contact with a PPP more likely.
