ABSTRACT
Semiochemicals are widely used by government and commodity groups to detect new pest infestations. There are presently three primary uses of survey traps: (a) trap grids are used to detect introductions of chronic pests such as fruit flies and gypsy moth, and they are maintained at high-risk areas such as urban centers, airports, and harbors; (b) a Cooperative Agricultural Pest Survey program has been established in the United States between federal and individual state agencies to detect the introduction of new exotic pests [74]; and (c) monitoring programs have been established to demonstrate pest-free production and storage zones as a prerequisite for exporting various agricultural commodities to specific countries [129].
