PINK WAX SCALE

T HE pink wax scale is a comparatively new introduction into Western Australia and so far has been recorded only from the metropolitan area. Like all scale insects it is a sap-sucker a n d in common with the better known white wax scale encourages the prolific growth of sooty mould fungus on affected plants. Should this pest be- come established in commercial orange groves, expensive spray t r e a t m e n t may be necessary and so every effort should be made to control the present outbreaks, and to prevent the spread of the insects to clean districts.

The following notes have been prepared to assist fruit growers and home gardeners in identifying t h e pest and applying the most effective control measures:—

DESCRIPTION

In its adult stage the scale is covered by a mass of pink waxy material not u n - like a small blob of candle grease. The insects show a preference for tender growth and cluster on young twigs and leaves.

LIFE HISTORY

The young crawlers emerge from eggs deposited under t h e female scales and become active in t h e early summer. A second generation may appear on the leaves in March or April.

HOST PLANTS

Under local conditions pink wax scale has already been found infesting the following plants:—Pittosporum, umbrella trees, magnolias, lilli-pilli, Irish straw- berry, ivy and N.S.W. box. In Queensland

25

and N.S.W. the host list includes various types of citrus and quite a few bush plants.

TYPE OF DAMAGE

As the pink wax scale is a sap-sucker a heavy infestation of this pest may affect the general health of a tree or shrub.

Furthermore, the honey dew excreted by the scale may so encourage the growth of sooty mould that commercial fruit may require cleaning before it is suitable for market.

CONTROL

White spraying oil at the rate of 1 gallon to 40 gallons of water or 2 table- spoons to 1 gallon of water is used against most citrus scales and will kill the crawlers of the pink wax scale. Unfor- tunately, however, once the waxy cover-

ing is well developed a soda spray is necessary and the following mixture is recommended.

White Oil—1 tablespoonful (1 gall.).

Soda Ash—4 oz. (10 lb.).

or

Washing Soda—i lb. (20 lb.).

Water—1 gallon (40 galls.).

Spray treatments should be given after the main hatching has been completed.

For the first brood this should be early December and for the second brood about the end of March.

The spray should not be applied during a heat wave. Foliage burning may follow its use on some delicate plants.
