WEEKLY INSECT
BYTES for September 21, 2007 .
The insect pest control updates
presented below are for the south-central part of Pennsylvania
based on observations in Adams County, PA.
- The CM flight most likely
will continue until late September, with continuous potential
of new larvae. If a control treatment(s) may be warranted, then
CM granulosis virus, which has 0 day PHI, should provide adequate
control of CM;
- The fourth generation Oriental fruit moth (OFM)
adults are still present in many apple orchards. The OFM flight,
if the weather continues to be warm, can last until late October.
If necessary, broad spectrum insecticides such as Imidan, Avaunt,
or neonicotinoid insecticides should provide good control;
- Stink bugs and plant bugs may be feeding on
maturing apple fruit. Broad spectrum insecticide application,
if needed, should provide adequate control of these two pests;
- The updated information with various
insecticides Pre-Harvest Intervals (PHI) can be found in the August
issue of the Fruit Times newsletter at: http://fruittimes.cas.psu.edu/FT2608.pdf
