30 July, 2012
July 25 was an important day for forest protection in South Africa, as
it marked the first release of Selitrichodes neseri, the biological
control agent for the eucalyptus gall wasp, Leptocybe invasa. Leptocybe

New pest of Eucalyptus, Glycaspis brimblecombei, in South Africa
27 July, 2012
A new invasive insect on Eucalyptus was recently detected in the Pretoria
area by Prof. Stefan Neser. Although the identity must still be confirmed,
we are almost certain that this insect is the red gum lerp psyllid,
Glycaspis brimblecombei. This insect is a very serious pest of Eucalyptus,
and it is important that we quickly ascertain its current distribution in
the country and work towards a control strategy. More information will be
sent shortly, but I attach a past pest alert that provides basic information
A drop in demand for woody biomass in the US reduced biomass prices in the South, Northeast and the West during the 2Q/12
24 July, 2012
Prices for mill and
forest biomass fell in most major consuming regions of the US in the 2Q/12,
according to the North American Wood Fiber Review. The main reason for the
declining prices is the continued fall of natural gas prices to levels not seen
in ten years.

Can changes in forest management regimes in British Columbia mitigate the sharp reductions in timber harvests caused by the mountain pine beetle?
17 July, 2012
Timber harvests in British Columbia plunged by
over 40 percent between 2005 and 2009, but have since recovered and were close
to the 25-year average in 2011. As a consequence of the infestation of the
mountain pine beetle, long-term log supply is estimated to be about 20 percent
below historical levels unless different management regimes are implemented.

Important news about the release of the wasp to combat Leptocybe. Since hearing that we have permission to
release Selitrichodes neseri, a potential biological control agent for
Leptocybe invasa, we have been inundated with requests to release the wasp in
different areas. We are working very hard to build up populations of the
parasitic wasp to release as soon as possible, and as widely as possible.
Wood fiber costs for the European pulp industry have fallen from the record highs of 2011

Wood fiber costs, which can
account for up to 70 percent of the production costs for a pulpmill, fell in
many markets during the 1Q/12, according to the Wood Resource Quarterly. The
biggest declines were seen in Western Canada, Europe and Brazil, while Chile,
Australia and New Zealand experienced some minor price increases for pulplogs
and chips during the quarter.
