The C.R.S. PheroLure ® is designed for use together with an Insect Science ® C.R.S. Kit.
To assemble the Insect Science ® C.R.S Kit, open the scale card so that the sticky side is on the
Take the galvanized wire supplied and put it through the holes on top of the scale card.
Remove the lure from the white foil sachet and push it onto the wire just above the scale card and
bend the wire to form a hook.
Fields should be divided up into monitoring areas of approximately 2 hectares; this is the
maximum area that can be monitored by a single scale card.
The scale card should be placed in the middle of the 2 ha area.
A higher card density may be necessary where the orchard is not uniform in shape, where there
are steep slopes and gulleys or when tree growth is very dense.
Prevailing winds may also affect the card and PheroLure ™ effectiveness and therefore a higher
density may be necessary.
Placement of the scale card in the tree:
Suspend the scale card on the western side in the top third of the tree, 300mm inside the tree line
using the wire supplied.
Identify every scale card with a number for reference and recording purposes.
Place scale cards out at the beginning of the production season.
Lures should be replaced every 4 weeks. Remove the used lures from the orchard and destroy
Replace the white scale cards weekly during monitoring period.
Bend the wire open to remove the old card and replace with new card making sure that the sticky
side is outside.
It is imperative that counts be recorded weekly and preferably on the same day each week.
After the white scale card is removed from the tree count all the insects inside the 12 printed
squares on both sides of the card and multiply by 5 to calculate the total number of insects caught.
Record the number of insects caught and the date.
The counts obtained from the white scale cards are an indication of the population pressure and dynamics and therefore consultation with your local pest management advisor for accurate interpretation of the counts is advisable.
