Note: This table illustrates the number of live insects that, if detected in a 1-kg sample, will result in an infested grade under the FGIS insect-infestation standards.

"Weevils are rice, granary, maize, and cowpea weevils, as well as the lesser grain borer.

'Other live insects include the grain and flour beetles, moths, and vetch bruchids.

6. Control of insects with fumigants if populations become excessive

Insect attractants (pheromones) and new methods of trapping insects have been developed to detect insects in stored grain (24). Traps are more efficient than traditional grain trier and sieve monitoring methods because they often can detect insects that would otherwise go undetected. There has been increased interest in recent years in new programs to sample insects with traps and to use this information in control programs. The grain storage industry is becoming increasingly more involved in Integrated Pest Management (IPM) programs by taking steps to manage insect populations, instead of reacting after large populations are detected and IDK are present.
