Pheromone lure for Western Flower thrips causes thrips to move to the top of the crop resulting in earlier detection and estimation of population size
Fits well into a thrips ICM program with other biological control agents and/or chemical spray treatments.
How It Works
Thripline contains a synthetic version of a sexual aggression pheromone produced naturally by male occidentalis. It attracts both male and female thrips into mating aggregations. It will not attract thrips from outside of the general crop area.
The pheromone is encapsulated in rubber lures (septa) and is released gradually over several weeks.
Instructions for use
Open a pack of sticky traps and the Thripline foil sachets of 10 lures (septa) in the crop.
Hang traps 12-20 inches (30-50cm) above the top of the crop. Strip papers from both sides of each trap and apply a lure directly to sticky surface on lower part of the trap.
The pheromone is in open ‘cup’ of the lure.
Place lure horizontally. Thripline pheromone releases can be reduced if this ‘cup’ fills with water, which can happen in crops with overhead irrigation.
For monitoring purposes, use one lure for every 1,000 ft2 (40 traps/acre) with a sticky trap.
May enhance contact chemical control by luring thrips to surface. Hang 1 lure/1,000ft2 near greenhouse circulation fans for one hour before treatment. Remove lures after treatment for future use.
Replace lures and traps every 3-4 weeks or more frequently if they become covered with thrips.
Storage and transport
Lures (in sealed packages) can be kept in a refrigerator at about 39°F/4ºC for several weeks or months.
They may be kept for up to two years at -0.4°F/-18º
Once foil packets are open, use product immediately.
