Abstract:
Grains of field crops, such
as wheat, maize, faba bean and white
bean, are considered strategic food for
humanity worldwide and Egypt.
Unfortunately, percent losses of grains
quantity may reach to 15-30%, as a result
of stored product insect damage, and the
losses increased dramatically in the last
years, as an outcome of quickly
productions of these pests. Experiments
were conducted on infrared thermal
imaging that demonstrate early detection
of infestation by stored product insects in
wheat, maize, broad bean, white bean and
bean grains. The imaging is dependent on
subtle significant differences in
temperature between infested and healthy
grains. Because the thermal imaging data
are digital, computer programs can be
used to analysis differences in
temperature and mining figures explained
for that. Results revealed that the use of
thermal imaging offers an alternative
method to detect an insect infestation.
Data concluded that thermal imaging has
the potential to identify whether the grains
of crops that tested are infested or not, but
is less effective in identifying which
developmental stage is present. Moreover,
it could apply this technique easily on a
large scale in silos, storage, mills and
granaries without negative impact on
quality of stored grains.
