Quarantine identification method for double-hooked long-winged pheasant
1 Scope of application
This standard is applicable to the quarantine and identification of double-winged long-winged pheasant in inbound and outbound wood, bamboo, rattan and its products and packaging materials.
2 Principle
Spread through wood and bamboo rattan materials, products and packaging bedding materials. The morphological and biological characteristics of the double-winged long-winged pheasant are the development of this standard.
The basis of the quarantine identification method.
3 Instruments, utensils and pharmacy
Stereo microscope, saw, knife, forceps, label, anatomical needle, scalpel, brush, finger tube, insect box, 75% alcohol, 0.5% to 1% C
Triol.
4 on-site inspection
4.1 Surface inspection
On the spot, check whether the surface of wood, bamboo, rattan and its products, packaging materials has live insects crawling or dead insects attached. Observe the appearance.
There are holes and swarf.
For skinned wood, the bark should be peeled off to see if there are holes and swarf.
Multi-level inspection of the timber in the cabin and the carriage.
4.2 Section inspection
For wood or bamboo vines that are suspicious or found to have pupils and swarf, use a saw and a knife to check the presence of adults or larvae. Observed
Is there a larva feeding parallel to the longitudinal direction of the material, the diameter of the tunnel is about 6mm, the length is up to 30cm, the depth is 5cm~7cm, and the constant pit
The roads are juxtaposed or interlaced, and the tunnel is filled with dust. The rattan material can be judged according to its toughness, and the toughness of the victim rattan material is affected.
Broken, according to which pupils and worms can be found.
