Pheromone Monitoring Systems
œcos supply dedicated monitoring systems as shown below.
We also produce a range of pheromone lures which can be supplied with trapping systems or separately as required. A full list of pheromones available is shown below. Pheromone lures should not be removed from their airtight aluminium packaging until ready for use. For short term storage, lures should be stored at 4ºC and for long term storage at -18ºC i.e. freezer. All pheromone lures have a shelf life of two years if stored correctly.
Pheromone traps provide key monitoring information to growers about potentially crop damaging moth species. They provide an early warning of attack from the Caterpillar part of the moth life cycle. This helps determine what pest control strategy should be adopted. The pheromone used in the traps is always specific to one species. Most traps use a sex pheromone, which attracts the male moth into the trap. Some traps use attractant lures.
Choice of Traps
The most commonly used trap is the Delta trap. The pheromone lure in the trap attracts the adult moth and catches it on the sticky insert inside. These inserts can be replaced once full of moths. The Delta trap is made from treated cardboard, which is designed to last one season and should be replaced the following season with a new Delta trap. A more recent innovation is the Castellation trap, which does not need sticky inserts, as once the moth enters the trap it can not escape. The trap is made from clear plastic, so the amount of moths caught can be viewed to check numbers. For large moth species it may be necessary to use McPhail or Funnel traps [both made from UV strengthened plastic]. These traps are also less affected by dust, which can quickly fill up the sticky surfaces of a Delta trap in a field crop situation. Castellation, Funnel and McPhail traps can be re-used if using the same pheromone lure, it is not possible to re-use traps using different types of lures. Plastic traps can be washed and re-used, cardboard traps last for one season only.
