Thrips Monitoring System
|
The Thriplineams pheromone system works by giving a mating signal to the Western Flower Thrips. The male and female thrips then emerge onto the top of the crop looking for a surface, for example a flower, on which they can display. The Taki-traps® act as an alternative display area and in the process catch the thrips. Trials have indicated that the greatest activity is at dawn or before dusk.
Thriplineams contains a synthetic version of a sexual aggregation pheromone for Western Flower Thrips, Frankliniella occidentalis1. The natural pheromone is produced by males of F. occidentalis and attracts both males and females into mating aggregations. Thripline ams combines this pheromone with Taki-traps ® to catch the 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.
Open the pack of Taki-traps® and the foil sachet of 10 lures (septa). Peel back the paper from the lower section on one side of each trap and apply a lure directly to the sticky surface, with the open ‘cup’ of the lure uppermost. Allow the paper to cover the lure and hang the traps 30-50 cm above the top of the crop. Strip the papers from both sides of each trap once the trap is in place. For monitoring purposes, use 100 traps/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.
The lures (in sealed sachets) can be kept in a refrigerator at about 4ºC for several weeks or months. They may be kept for up to 2 years at -18ºC. Once foil packets are open, use product immediately.
