REVIEW OF PHEROMONE-BAITED STICKY TRAPS FOR DETECTION OF STORED-PRODUCT INSECTS

Sticky traps are highly useful for the detection of low-level insect populations which are otherwise difficult to detect in processed commodity storages. Even where insect populations may be moderately high, as in the storage of unprocessed agricultural commodities, they are useful for making management decisions on insecticidal treatments and safe storage periods. These traps enable warehousemen to locate infestations and take corrective action while the infestations are still small and before they spread to other commodities. Recently, these traps have been used to demonstrate monitoring of feral populations of stored-product insects in some climatic areas of the world. Feral populations likely serve as reservoirs of insects for infestation of stored commodities, a possibility of much significance for storage management.
