FLORIDAForests - Spring/Summer 2017 - 22

The SPB Prediction Chart model provides a
forecasted level of SPB severity based on the
number of SPB captured per trap per day,
and the % SPB (vs. their major predator, the
checkered clerid beetle) per trap per day.

county trap had counts predicting
outbreak status for its location in the
northern part of the county. Saint Johns
has observed comparatively higher SPB
activity for the past five years due to
its abundance of conservation easement lands that are overstocked and
in need of maintenance.
It is difficult to make a definitive
statement on SPB population trends
due to the numerous environmental factors that influence the insect's
biological dynamics. It is noteworthy to mention that the number of
counties predicating high-reaching SPB activity in this year's survey
has not occurred since the outbreak
years of 2000-2002. Since then, the
SPB Prevention Program has been

successful in reducing available habitat for the beetle by encouraging private landowners to thin overcrowded
and stressed pine stands that favor
SPB infestations. However, due to
the elevated numbers of SPB and
low "predator to prey" ratios collected from the traps in this year's
survey, foresters are urged to be on
the lookout for localized and sporadic infestations on stands that are
over-stocked, over-mature or have
poor soil drainage.
As in previous years, all counties
in FFS Districts/Centers 1-12 will be
asked to conduct an initial aerial SPB
detection survey. Procedural guidelines for aerial surveys, ground checking and reporting are available to FFS
foresters on the Forest Health website
at http://www.freshfromflorida.com/

Because of limited survey inputs,
a vast resource of potential habitat
and the limitations of the predictive model, the forecast presented
here cannot be expected to be 100
percent accurate. Low/static SPB
predictions do not guarantee that
troublesome infestations will not
develop on a local or limited basis

in some counties. Activity predictions
are likely to be more accurate for the
5-mile radius region around each trap
than for the county as a whole. Given
the limitations of the forecast, the
recent drought and/or flooding experienced in some areas of the state and
the potential for environmental conditions to change after the survey, areas
of suspicious pine mortality should be
promptly inspected for evidence of SPB
in the coming months.
Sincere thanks to all the foresters
who were involved in installing traps,
making weekly collections and submitting samples for processing. Please forward any or all of this report to anyone
you think may be interested. *
