Traps are used to monitor pest populations and some offer a means of pest control. They take various forms from coloured sticky traps to pheromone lure attractant traps. Some of the most popular types are listed here.

How they work: Used to detect pest populations early before they cause damage to the crop, to monitor the success of a control measure and to provide data on long term pest problems. These traps have a dry glue covered with a paper sheet preventing traps sticking together in the pack. Traps remain sticky until covered in dust or dead insects. When monitoring replace regularly - usually every 4 weeks. Dry glue allows insect recording with a pen on each trap. For easy monitoring of insects, traps can be cut up and the paper removed in sections.

Species attracted: Use yellow traps for detecting activity of aphids, leafminer, sciarid, thrips and whitefly. Use blue traps for Western Flower Thrips. 

How to use: Suspend traps about 20 cm above the height of the crop. Full instructions and monitoring sheet included in each pack. 

Rates of use: Use one trap for monitoring per 200 m2

How they work: Used to detect and control pest populations. The trap is supplied on a roll as a two sided trap with a wet glue. It is designed to be rolled out above or alongside the crop. 

Sticky Checker (sticky trap insect identification): A guide to the identification of smaller insects found on sticky traps (text is in six languages). One poster shows insects in actual size, the second as under a 10x hand lens. Includes thrips, aphids, leafhoppers, leafminer, whitefly, fungus gnats (sciarid), shore fly, various parasitic insects and blossom beetles. 

How they work: Contains a synthetic version of a sexual aggregation pheromone for Western Flower Thrips Frankliniella occidentalis. The natural pheromone produced by the male WFT attracts both male and female into mating aggregations. Designed to improve sensitivity of monitoring traps for WFT. 

Species attracted: Western Flower Thrips (Frankliniella occidentalis) only. 

How to use: Traps should be hung 30-50 cm above the crop. 

Rate of use: For monitoring purposes use 100 traps per ha placed 10 metres apart along rows. In mixed cropping situations with possible variable thrips populations use more traps. Lures and traps should be replaced every 3 - 4 weeks or more frequently if covered with insects and monitoring is no longer possible.   

How they work: A powerful pheromone attracts the winged male mealybug onto sticky traps which would not normally attract them and used to monitor citrus mealybug activity. Unlike the female, the males are short-lived and fly. 

Species attracted: Citrus Mealybug Planococcus citri alone. Other species of mealybug are not attracted. 

How to use: The rubber septum containing the lure is placed on or hung in front of a yellow sticky trap. The lure is active for 6 weeks. 

Adult moths lay several hundred eggs and on hatching young caterpillars disperse and feed on the plants. After a few days, the young caterpillars spin leaves together and feed inside protected from sprays applied for several weeks before pupating

Type: Pheromone traps for use on ornamental crops to aid timing of tortrix control measures

How they work: A sticky base in the delta trap is baited with a specific sex pheromone lure which attracts male moths. Traps are monitored to time control measures. 

Species attracted: Each pheromone trap is specific to the appropriate species of tortrix moth. On ornamental crops the Carnation tortrix is frequently the most common species. 
More recently the Light Brown Apple moth has been found along the south coast. Separate traps are required for each species. 

When to use: Whenever there is a risk of attack. Usually installed at the beginning of the season and maintained well into the autumn. 

How to use: The rubber septum containing the lure is placed on or hung in front of a yellow sticky trap. The lure is active for 6 weeks. 

Rate of use: A minimum of 2 traps per species is recommended. For outdoor crops use one trap per 1 - 2 ha. For protected crops use 2 traps per 1000 mstructure. Place just above crop height with 50 m between each trap. Lures and stickybases need to be replaced every 5 - 6 weeks. Each trap comes with a set of 4 lures and sticky bases. Lures should be stored in their sealed foil wrapper in a deep freeze or coldest part of a refrigerator until required. 

Specific Pheromone traps are available for: Plum fruit moth, fruit tree tortrix, summer fruit tortrix, codling moth, strawberry blossom weevil. Traps are available for a wide range of other pest species in a large number of situations.
