GB/T 41278-2022 in English

GB/T41278-2022 is an important technical specification for the detection of stored grain and bean pests in my country. It adopts the ISO16002:2004 international standard and makes technical adjustments based on the actual needs of domestic grain storage. The standard provides systematic guidance for the application of devices such as probe traps and cup traps.

The standard deleted the content related to dichlorvos, methyl bromide and other chemical agents banned in my country in the original ISO standard, reflecting the concept of green grain storage. The new clause 7.1 clarifies the principles for the combined use of different types of traps to improve the detection coverage.

Bulk Grain Testing Key Points

• Probe traps should be used in pairs and placed at a depth of 10-30cm and 200cm below the grain surface respectively
• For mite detection, the moisture content of the bait should be maintained, and a replacement cycle of 7-10 days is recommended

Packaged Grain Testing Specifications

• Flying Pest Traps should be hung 1.5m from the ground
• The interval between traps at the base of the stack should be controlled at 3-6m

A central grain reserve warehouse adopted lid-barrel trap and the probe trap realizes three-dimensional monitoring of major pests such as corn weevils and grain borers, and increases the pest detection rate by 40%. A dynamic database of insect conditions is established through standardized result recording tables (including 16 parameters).

With the development of stored grain ecological theory, trapping detection has shifted from single chemical fumigation to integrated pest management (IPM). This standard introduces biological technologies such as pheromone trapping, reflecting the technical upgrade path of my country's stored grain pest detection from passive treatment to active early warning.
