should you take this survey?
is know that several species of stink bugs and leaffooted bugs attack
pecan nuts by piercing through
the shell and causing damage in the kernel therefore a reduction on
kernel quality reducing the price at the time selling your annual
crop production. It is important to evaluate the economic impact of
this insect on pecan production in order to develop better programs
therefore better management of this insect in your crops. All the
information generated on this survey is confidential and data obtained
will be tabulated and summarized and later on reported, all the personal
information include in the survey will be confidential.
should know about stink
bugs and leaffooted
adults of stink bugs have piercing and sucking mouth
parts and feed on plant juices. Feeding by adult stink bugs prior
shell hardening results in a condition known as "black pit"
and will cause nuts to abort. After shell hardening, nuts stay on
the three but black spots form on the kernel at the feeding site.
Kernels with black spots have a bitter taste and are considered inedible.
Several species of leaffooted bugs are associated
with pecan. Prior to shell hardening, feeding on nutlets by these
insects causes a condition referred to as "black pit" also,
which causes nutlets to abort. This same condition is also caused
by several species of stink bugs as mentioned before. After hardening,
it is thought that feeding by leaffooted bugs is restricted to the
shuck with little or no kernel spotting.
bug damage, notice the "black pits" produced by the insect.
