Introduction
Analysis of the core content of the standard
This standard specifies the quarantine and identification technology system for Anoplophora chinensis, including three modules: on-site inspection, laboratory identification and specimen preservation. The standard systematically integrates the morphological identification characteristics and molecular biological detection technology of this insect species for the first time.
Comparison of key technical parameters
| Identification indicators | Adult characteristics | Larva characteristics | Detection instrument |
|---|---|---|---|
| Body length range | 25-45mm | 38-70mm | Stereomicroscope |
| Key identification | Arrangement of white spots on elytra | "convex" pattern on pronotum | |
| Preservation requirements | Needle-inserted specimens | Ethanol-glycerol solution |
Key points for the implementation of the standard
Optimization of the quarantine process
The standard innovatively proposes a three-level screening method:
- On-site initial screening (inspection of the emergence holes and borer tunnels)
- Dissecting microscopic examination (screening for xylem larvae)
- Culture verification (artificial breeding at 28-31℃)
Difficulties in morphological identification
It is important to distinguish Anoplophora glabripennis from closely related species:
- Anoplophora glabripennis (irregular white spots)
- Anoplophora dasyphylla (vertical stripes)
- Anoplophora velvetii (blue hairs)
Technical evolution analysis
Compared with the 2009 version of the old standard, this version has the following major upgrades:
- Newly added Biological incubator standardized parameters (humidity 90-95%)
- Detailed description of the microscopic features of the larval vesicles
- Added a list of host plants for 19 families and 29 genera
Implementation suggestions
Quarantine site
For wooden packaging from the epidemic area, the following should be checked:
- The junction between the stem and the root of the seedlings
- Branches with a cross-sectional diameter ≥3cm
- Peak emergence period from May to July
Laboratory construction
Required configuration:
- Stereo microscope with macro lens
- Constant temperature and light culture system
- Specimen digital management system
