PURPOSE AND APPLICATION

Target pest:

Western Flower Thrips (Frankliniella occidentalis).

Crops:

Many vegetable and flower-decorative cultures of protected ground.

Application:

Position traps and lures just above the crop (e.g with the base of the trap 10 cm above the crop) or place parallel with the crop rows, taking care to avoid contact between the roll and plant canopy. Position the traps so that they are clearly visible in the crop, but not too far from flower height, as thrips are poor fliers.

Pheromone lure for monitoring and capturing Western flower thrips, also known as California thrips (Frankliniella occidentalis).

Frankliniella occidentalis,the western flower thrips, is a major worldwide pest, causing economic loss to a wide range of flower, fruit and vegetable cropssuch as chrysanthemum, pepper, cucumber, strawberry and raspberry.

The western flower thrips has spread around the world through international trade. Its ability to breed on many species of host plants (>240 known hosts), and its ability to develop resistance to insecticides, has contributed to its success. Symptoms of plant damage by thrips feeding include: bud deformation, shape distortion of fruits or vegetables during growth and a range of leaf spots, scars, silvering and bronzing. Both adult and larvae feed throughout the plant and leave the crop susceptible to secondary fungal and bacterial infection resulting in moulding and wilting. The western flower thripsis a vector of some important virus diseases such as Tomato Spotted Wilt Virus (TSWV) and Impatiens Necrotic Spot Virus (INSV). Entire crops may be left unmarketable unless infestations are managed.

Lures handling:

Pheromone lures are a very sensitive tool. They can be affected by exposure to elevated heat and direct sunshine. Wear gloves to handle the lures as direct touching by hand may cause cross contamination leading to mixed catches in the trap. Some contaminants, such as nicotine, may have a repellent effect reducing trap catch.

The western flower thrips aggregation pheromone lures can be changed every 6-8 weeks to get the most accurate results.

Thripnok remains active as long as there is liquid visible in the blister pack, which is up to three months in cool conditions.
