Thanks Lance
The topic has always been of interest to me... Back in the 1980s, I decided=
to go back to University to work toward an Doctorate. The topic was evalu=
ating the differences in forest ecosystem structure between sites that had,=
essentially , been treated annually for suppressing spruce pests (budwroms=
) for up to 50 years, with control sites.
This was based non the observation that at such sites there appeared to be =
a much greater incidence of |snags| than untreated sites I had hypothesize=
d that these treated sites were shifting more toward bacterial and fungal d=
ecomposers as opposed to ones that were kick-started by mechanical decompos=
ers such as Cerambysics, buprestids, and sawflies.
Unfortunately the funds I had managed to line up were pulled during the fir=
st budget cycle of the Mulroney administrattion, so I did not pursue it.
Andrew

Hi Andrew,
The quote comes from an author (a junior author, I stand corrected David) n=
ot by me. I included it because a comment was made in an earlier email abou=
t fungicide effects versus pesticide targets. The author is expressing the =
opinion that, at least in the USA, the effects of fungicides on non-target =
organisms and processes in the environment are not fully appreciated. Your =
comments seem to support his general position concerning the fact that ther=
e are unanticipated environmental effects.
Coming back to Blake's original observation of a lack of insects, a measure=
of insect abundance has existed since the internal combustion engine began=
powering wheels. The simple car windshield transect survey. Most people re=
ading this have undoubtedly observed a many-fold reduction in the number of=
insects that get smeared on their windshield driving a familiar stretch of=
road in the summer then there would have been even ten years ago. I had ze=
ro tonight on a 70km suppertime drive, half of which is through agricultura=
l land. Conditions were clear and about 24C.
All the best,
Lance
