GB/T 37719.1-2019 in English

In-depth interpretation of GB/T 37719.1—2019 "Auxiliary Atlas for Inspection of Stored Grain Pests in Grain and Oil Storage"

1. Background and significance of standard formulation

GB/T 37719.1—2019 is an auxiliary atlas for inspection of common pests in grain and oil storage - Tenebrionidae. With the continuous expansion of my country's grain reserves, the problem of stored grain pests has become increasingly prominent, especially Tenebrionidae pests, which are extremely harmful to grain quality and safety and storage environment. The formulation of this standard provides an important reference for the rapid and accurate identification of these pests.

2. Comparative analysis of standard frameworks

3. Classification and characteristic interpretation of Tenebrionidae pests

Basic characteristics of Tenebrionidae:

• Various body shapes, long and slightly flat
• Hard body wall, mostly black, reddish brown or spotted
• Small head, anterior mouth, short antennae
• Compound eyes are often cut by cheeks
• Legs are thick and long, smooth or with thorns

4. Implementation suggestions and application guidelines

Implementation suggestions:

1. Use the inspection tools specified in the standard (such as magnifying glass, stereo microscope) for observation.

2. Ensure that the inspection environment is well lit and avoid interference from direct sunlight.

3. For difficult insect species, refer to the morphological characteristics comparison table in the atlas.

Summary

GB/T 37719.1—2019 provides important technical support for the grain and oil storage field. Through scientific inspection methods and detailed atlas comparison, the accuracy and efficiency of stored grain pest identification can be effectively improved.
