Introduction
This document describes a laboratory method of testing which gives a basis for the assessment of
the eradicant action of fast and slow acting wood preservatives and of deferred acting wood
preservatives against Hylotrupes bajulus. It allows determination of the lethal effect of a surface
application of a preservative product on a population of larvae previously introduced into the test
specimens.
The method simulates conditions in practice where a beam is treated, which is only slightly
attacked and where cutting away has not exposed insect tunnels. This represents a severe test of
the product.
In some particular instances, for example where the preservative is to be used on timbers of large
dimensions, laminated beams, blockboard, plywood and other panel products, other test methods
can be used to obtain complementary information on the effectiveness of the eradicant action of
a product. Such methods lie outside the scope of this document.
This laboratory method provides one criterion by which the value of a product can be assessed.
In making this assessment the methods by which the preservative may be applied should be taken
into account. It is further recommended that results from this test should be supplemented by
those from other appropriate tests, and above all by comparison with practical experience.
When products that are very active at low concentrations are used it is very important to take
suitable precautions to isolate and separate, as far as possible, operations involving chemical
products, other products, treated wood, laboratory apparatus and clothing. Suitable precautions
should include the use of separate rooms, areas within rooms, extraction facilities, conditioning
chambers and special training for personnel.

5 Test materials
5.1 Biological material
5.1.1 Hylotrupes bajulus (Linnaeus) larvae
5.1.2 Source of larvae
The larvae shall preferably be obtained from cultures reared according to the method described
in Annex B.
Larvae can also be taken from naturally infested wood, in which case they should be transferred
into sapwood of pine and stored for at least four weeks under the rearing conditions specified in
Annex B.
5.1.3 Provision of larvae
Carefully split or crumble infested blocks to extract larvae.
Keep the larvae separate from one another in glass receptacles for two or three days in the
culturing chamber (5.3.1) to check they are healthy.
5.1.4 Choice of larvae
Use only healthy larvae in the test.
NOTE A healthy larva can be recognized by ivory-white colour, its firm consistency and rounded
appearance, and by the absence of wounds or bites, which show up as dark marks. Healthy larvae react to
the touch by vigorous movement and attempts to bite.
Reject any larvae, which are shrunken or aged which have recently moulted, or which are in a pre-
pupal stage.
Weigh each larva and place it in a glass receptacle marking the receptacle with the weight of the
larva. Make up two groups with the weight ranges:
— 51 mg to 100 mg, and
— 101 mg to 150 mg.
Larvae with a mass larger than 150 mg in mass are unsuitable as they can pupate during the
course of the test.
5.2 Products and reagents
5.2.1 Paraffin wax, for sealing the relevant surfaces of specimens to be treated with solutions
in which water is the continuous phase.
NOTE Paraffin wax with a setting point of 52 °C to 54 °C has been found suitable.
5.2.2 Gelatine, for sealing the relevant surfaces of specimens to be treated with solutions in
which an organic solvent is the continuous phase.
5.2.3 Water, complying with grade 3 of EN ISO 3696.
5.2.4 Solvent or diluent, a volatile liquid that will dissolve or dilute the preservative but does
not leave a residue in the wood at the end of the post-treatment conditioning period that has a
toxic effect on the insects.
CAUTION — Do not use benzene or other solvents which pose a health risk.
