An EPPO study on wood commodities other than round wood,sawn wood and manufactured items

This paper summarizes the approach of a recent EPPO study and some of its key outputs. The study was commissioned to aid pest risk analysis and the development of risk management measures for movements of woodchips and other similar commodities. These wood commodities represent a significant pathway for the introduction of pests of trees into new areas, and the pathway is becoming more important as trade in such commodities increases. An indication of the relative risk of different commodities for different types of pest was proposed as a conclusion of the study. More information is now needed on the quantities and nature of the material being moved into and within the EPPO region, and the treatments to which it has been subjected. This may not be clear from commercial documentation and trade data so national plant protection organizations (NPPOs) are encouraged to gather and share such information from inspections of consignments.

The evaluation of permethrin for wood preservation

The toxicity of the synthetic pyrethroid permethrin (NRDC 143) to a range of wood destroying insects has been investigated. In tests using Hylotrupes bajulus, Anobium punctatum, Lyctus brunneus and Reticulitermes santonensis permethrin showed a similar order of toxicity to that of gamma-BHC. Although the toxicity of permethrin to adult A. punctatum was of the same order as that of gamma-BHC, the toxicity to larvae was rather lower. The implications of these results are discussed and it is concluded that, subject to further field evaluation, permethrin could provide an alternative to gamma-BHC and dieldrin in wood preservatives.     

Guidance on sampling to detect pine wood nematode Bursaphelenchus xylophilus in trees, wood and insects

The pine wood nematode Bursaphelenchus xylophilus is the causal agent of pine wilt disease. It is a quarantine pest for most countries in the world. Surveys for the occurrence of the nematode may be necessary in the framework of internationally agreed phytosanitary standards, in order to delimit infested areas or to demonstrate the absence of B .  xylophilus and thus to identify pest free areas. Import inspections of wood and wood products also need sound monitoring systems. It is obvious that the quality of survey/monitoring, as well as the results of diagnosis, are strongly dependent on the sampling procedure. Although, in the literature, numerous results of surveys and monitoring are documented, sampling procedures vary and there is no scientific or statistically based sampling system published for B. xylophilus . The current paper relates background information concerning the biology of the nematode, its vector beetles and the development of pine wilt disease and the influence of these factors on sampling procedures, and attempts to define a more systematic methodology.     

Assessing risks of pine wood nematode Bursaphelenchus xylophilus transfer between wood packaging by simulating assembled pallets in service

The risks of Bursaphelenchus xylophilus (pine wood nematode) transfer in relation to wood material were assessed. Combinations of infested and non‐infested adjacent boards, long‐blocks and blocks of Pinus pinaster, simulating assembled pallets, were assessed. For the recipient wood, pieces with natural moisture content (MC), heat‐treatment (56°C for 30 min in the core) and kiln‐drying to <20% MC were tested, along with in‐service boards from pallets. Donor and recipient wood materials were kept in direct contact at 25°C or 10°C, with nine replicates per treatment. Bursaphelenchus xylophilus was found to transfer rapidly at 25°C when the wood had an MC above fibre‐saturation point (>30%). Nematode reproduction was rapid and sustained, gradually declining to zero at 40 weeks. Bursaphelenchus xylophilus did not transfer to kiln‐dried or to in‐service wood with an MC below fibre‐saturation point, or to wood at 10°C. The key factors determining nematode transfer were the ambient temperature, the nematode load of the donor wood and the MC of the recipient wood, with a ‘barrier’ of 20% MC below which it becomes unsuitable for nematode transfer. This finding indicates that there is a limited risk of spread of B. xylophilus in treated and untreated solid wood packaging materials.     

Factors affecting the introduction of preservatives into wood

The various processes by which preservatives may be introduced into wood are discussed. Important variables affecting rate and depth of preservative penetration are considered. As well as process variables such as applied pressure and treatment time, it is shown how mass flow processes are affected by carrier fluid viscosity and surface properties. Because of anatomical variation, wood permeability varies greatly both within and between species. Hence it is necessary to select species carefully when treatment is required. The mechanism of diffusion treatment is discussed and it is shown that this process can provide an effective treatment method for otherwise refractory species.
