Quarantine identification method for mountain pine
1 Scope
This standard specifies the quarantine and identification methods for the size of the mountain pine.
This standard applies to the quarantine and identification of mountain pine mites.
2 Principle
2.2 The adult larvae of the genus Pinus sylvestris are transferred to other tree plants after emergence, and they are mated in the bark to complete a new life generation.
2.3 Distribution, host and adult morphological characteristics, transmission pathways and biological characteristics of Pinus sylvestris var.
in accordance with.
3 instruments and reagents
3.1 Instruments and appliances
Stereo microscope, scissors, forceps, micro scalpel, anatomical needle, petri dish, slide, coverslip, alcohol lamp, beaker, insect needle, three-level
Table, specimen bottles, labels, etc.
3.2 Reagents
Soaking solution (glacial acetic acid. formalin. 95% ethanol. distilled water = 4.6.15.30), 75% ethanol solution.
4 on-site quarantine
4.1 The size of the mountain pine is mainly caused by the xylem and phloem of the wood. During the on-site inspection, the aphid wormhole and aphid excrement are mainly checked.
In order to harm the tunnels, adult feathering holes, etc., the symptoms of the found aphids and aphids are sampled, and the found pests are collected.
4.2 Perform a necropsy on the wood where the symptoms of aphids are found and carefully remove the mites.
5 Laboratory identification
5.1 Preparation
5.1.1 Bring the larvae and eggs to be reared together with the wood and bark samples of the relevant parts back to the laboratory at a temperature of 25 ° C to 30 ° C and humidity.
It was observed in 70% of the breeding environment and was identified after growing into adults.
5.1.2 When the insects, larvae, etc. to be observed and identified are cleaned and arranged, and there are dirt or dust on the surface, use 75% ethanol or match
Soak the placed soaking solution and soak it.
5.2 Identification
5.2.1 Main characteristics of adult genus
--- The back view of the head; visible dark brown to black, with a strong luster.
--- Compound eye long ellipse.
--- Ten corners of the tentacles, the hammer-shaped flat cake, divided into four sections, the top is flush.
--- The front chest plate is flat, no squamous tumor area, with engraved points and hairs, and the middle of the front edge is angularly inscribed.
--- The two coleoptera base edges are each protruding, synthesizing a parallel double arc, the base edge is raised, and there is a column of serrations.
---The outer edge of the 胫 section has a dentition.
