Recommendations for the use of the Pheromone Trapping System for Epiphyas postvittana (Light Brown Apple Moth)
 Species Name:          Epiphyas postvittana  (Family:  Tortricidae)  Light Brown Apple Moth

Pest Status:               Serious pest of a range of Hardy Nursery Stock and Fruit Crops

Generations:             Normally 2 generations per year

Trap:                           The Delta trap is recommended for this insect.

Trapping Season:     March until October
Trap Placement and Density for Monitoring:
Outdoors:  Traps should be deployed in an open area where the crop susceptible to attack is being grown.  The traps should be mounted on stakes and the height adjusted so that the trap is at or just above the height of the crop with 50m between each trap.  One trap should be sufficient to monitor up to 2 hectares of a uniform field.  In the case of irregular crops 1 trap per hectare is recommended though in all cases a minimum of two traps should be used regardless of the field size.
Indoors:  Traps should be suspended from the roof of the glasshouse or polytunnel so that the trap is at crop height.  Use two traps per glasshouse or polytunnel.
Use of Trap: Assemble the trap according to the diagram provided. 
Use of Lures:  The lure should be kept in the sealed packet until it is needed.  Do not try to open or pierce the capsule; just lay it in the centre of the sticky base.  Dispose of the sachet and used lures well away from the trapping area.
Change of Lures and Trap Servicing:  Lures should be changed every 6 weeks or earlier.  The sticky inserts should normally be changed when the lures are changed.  In situations where high insect catches or dusty conditions lead to the deterioration of the glue surface, the inserts should be changed more frequently.
Observations and Data Recording:  Catches should be recorded weekly in low populations but more frequently where populations are high.  Record the trap catch on a trap record sheet.
Selectivity:  The traps may also catch odd non target tortricid species.  If in doubt about which species is present or when to spray please contact your Adviser.
Note:  To avoid affecting the efficiency of the trapping system it is strongly recommended that traps be used for only the one species.  Never use the lures for other species in this trap.
