Attractant for Chinese fir longicorn

[Product characteristics] Specific, non-toxic, harmless, easy to operate, easy to measure and prevent

[Control Objectives] Semanotus bifasciatus hosts ornamental trees such as Siraitia grosvenorii, Alder cypress, Platycladus orientalis, Cypress chinensis, Cedar fir, Cryptomeria fortunei and Pinus tabulaeformis. The larvae infect the branches, dry cortex and sapwood by feeding on each other. The surface of the xylem is corrupted into curved and irregular tunnels, leaving sawdust and insect dung in the skin, thus destroying the conduction function of trees.

[Biological characteristics] Adult, about 10 mm in length, slightly flat cylindrical, black-brown to brown. There are two black transverse broadbands in the center and the end of the forewings, brown and yellow between the two black bands, and camel in the front of the wings. Egg, 1.6 mm long, oval, white. Last instar larvae, 15mm in length, Milky white, slightly flat cylindrical, slightly broad chest, head yellowish brown, insufficient. Pupae, about 15 mm long, light yellow. Beijing is an annual generation. Adults overwinter in the pupa chamber of branches and trunks. At the end of March the next year, adults bite a hole in the bark and emerge from the hole. Adults like to lay eggs on the cracks in the bark of weakened or newly transplanted trees and newly cut logs. There are 2 to 5 eggs in each place. Each female lays dozens of eggs. The egg period lasts for 10 days. The larvae hatch in the bark in early April, causing damage and discharging a small amount of wood debris. The larvae eat under the bark, and the bark falls off easily. In mid-late May, when larvae infested trees or branches around a circle, the stems and branches above the injured part died. In mid-June, the larvae penetrated into the depth of 2-3 cm of wood, pupation emerged in the tunnel in early October, overwintering with adults, and the newly transplanted trees or trees with weak vigor were the important conditions for the occurrence of the insect. The strong trees were seldom harmed. Generally, the withered and red cypress leaves have not yet fallen off. The insect mostly lives in the branches and mostly migrates in the second year.

[Main Components] Attractant for Chinese fir longicorn

[Sustained Release Vector] Sustained Release Bottle

[matching trap] insect pheromone longicorn trap

[Mechanisms of action] A plant-derived attractant was developed based on the important role of plant volatile odor in host search, nutrient uptake and oviposition of Chinese fir longicorn. The plant-derived attractant prepared by extracting the volatile components from the weak wood of Platycladus orientalis and adding micro-synergists has strong attractant effect on host search, nutrient uptake and oviposition of Chinese fir longicorn beetle, and can capture the trapped adults with a matching trap.

[Use technology]

1. Material: insect pheromone longicorn trap, bait, slow-release bottle, wire.

2. Control time: The adult emergence of the target pest begins at the early stage until the end of the adult activity period. Usually from the first ten days of April to the last ten days of September, the peak of pest occurrence is from the first ten days of July to the middle ten days of August. Attractants and matching traps should be set before adults fly in the control area.

3. Field settings: field cloth traps are arranged in parallel with 50 m row spacing and 50 m trap spacing. The trap can be hung on the open space of the field or on the non-host tree. The height (top) is 1.5-1.8m from the ground. It can also be adjusted according to the actual situation (generally, the diameter of the forest is less than 25m, only 10-15m outside the forest edge can be set traps; if the diameter of the forest is more than 25m, traps should be set in the open space of the forest), which is conducive to volatilization and lighting. The duration of validity is about 1 to 2 weeks, mainly determined by local weather conditions. It is necessary to replace a bottle or continue adding attractants after the volatilization of the liquid in the bottle to maintain the attractant effect.

[dosage] Each sustained-release bottle uses a dose of attractant, 250 ml.

[Environmental Toxicology] Plant extraction, non-toxic and harmless, pure natural, pollution-free, no residue. When used in forest and field, it can be used for human, animal, environment and environment.

Insect natural enemies are safe.

Matters needing attention:

1. The product should be sealed in a cool place for 18 months before use. Shake well before use and pay attention to fire prevention.

2. This product attracts male and female adults, so the trapping should be set before the adult stage.
