Advanced Monitoring System
Aggregation pheromone for Frankliniella occidentalis
Thripline ams is a proprietary product containing the aggregation pheromone of Frankliniella occidentalis.
The pheromone is impregnated into rubber septa, and is released gradually over several weeks. It is supplied as units of 10 septa sealed into foil sachets. Unopened sachets can be stored for up to 1 year in a refrigerator, or up to 2 years if kept frozen.
The product is produced and marketed under agreement with Keele University, who hold patents on the pheromone.
Thriplineams contains a synthetic version of a sexual aggregation pheromone for Western Flower Thrips, Frankliniella occidentalis. The natural pheromone is produced by males of F. occidentalis and attracts both males and females into mating aggregations. The Thrips will move to the top of the crop to look for mates and to display. Thriplineams combines this pheromone with Taki-traps® to catch these Thrips. The pheromone is doped onto rubber septa and packed into sealed foil sachets to maintain viability.
The product is designed to improve the sensitivity of monitoring traps for thrips, particularly at low levels of infestation or in easily damaged crops. This will permit growers to introduce additional control measures, such as Amblyline cu CRS, before Thrips populations reach damaging levels. In development trials it has also been noted that by moving to the more exposed areas of the plant to display, the Thrips become more vulnerable to the contact action of spray treatments.
The Thripline ams pheromone system works by giving a mating signal to Western Flower Thrips. The male and female Thrips then emerge onto the top of the crop looking for a surface on which they can form a mating display, for example a flower. The Taki-traps® act as an alternative display area and in the process catches and traps the Thrips.
Open the pack of Taki-traps® and the foil sachet of 10 lures (septa) in the crop. Hang the traps 30-50cm above the top of the crop. Strip the papers from both sides of each trap and apply a lure directly to the sticky surface on the lower part of the trap. The pheromone is in the open ‘cup’ of the lure. Release of the pheromone can be reduced if this ‘cup’ fills with water, as can happen in crops with overhead irrigation, so place the lure horizontally.
For monitoring purposes, use 100 traps per hectare, placed 10 metres apart along rows. For glasshouses with a diversity of crop types or ages, where populations of Thrips can be patchily distributed, traps can be placed closer together. Lures and traps should be replaced every 3-4 weeks or more frequently if they become covered with thrips.
