Description

Monochamus alternatus luring core

Technical Field

The utility model belongs to the technical field of the insect prevention and cure technique and specifically relates to a pine black longicorn lures core of luring.

Background

Monochamus alternatus (Monlchamus alternatus Hope) belonging to the order Coleoptera, Anoplophorae, Anoplopodae subfamily, Monochamus. The Monochamus alternatus hope not only damages trees with weak growth vigor by boring the larvae, but also damages xylem and phloem of the trees, causes insufficient or interrupted transportation of water and nutrients, seriously influences the growth of the pine trees, and even causes the pine trees to die in pieces. More serious is that the monochamus alternatus imago is also the main transmission medium of the pine destructive disease-pine wood nematode disease (Bursaphelenchus xylophilus), which is called 'cancer of pine' by researchers all over the world. The pine wilt disease was first discovered in Nakazaki city in 1905 in Japan, after which it spread. Since the first discovery of pine wood nematode disease on black pine of Shanling in Nanjing City in 1982, the wood loss of China exceeds 500 ten thousand meters³Resulting in a direct economic loss of about 25 billion dollars. The pine wood nematode disease destroys the natural landscape and forest ecological environment of China, poses serious threat to the sustainable and healthy development of the forestry of China, and brings great loss to national economy and people's life. The prevention and control of the monochamus alternatus hope can be realized by cutting off the transmission medium of the pine wood nematode diseaseThe key to bursaphelenchus xylophilus disease. At present, methods such as tree cleaning for death of diseases, chemical pesticide spraying, attractant prevention and control and the like are mainly adopted for treating the pine wood nematode disease, wherein the attractant technology has the characteristics of greenness, environmental protection, high efficiency and the like, and is one of the most common methods for preventing and controlling adult monochamus alternatus.

Patent application CN102986739A discloses an adult monochamus alternatus attractant. The attractant comprises an artificially synthesized compound prepared by adding reagents such as undecanol, thionyl chloride, ethylene glycol, metallic sodium and the like. According to the scheme, after the plant source pheromone and the monochamus alternatus gathering pheromone are mixed, a technology of releasing by a plastic slow-release bag is adopted, an effective synergist is lacked in a formula, the trapping effect is influenced, in addition, because the gathering pheromone and turpentine have different requirements on the volatilization rate, the gathering pheromone and the turpentine are mixed together and are all released by the slow-release bag, small molecular substances volatilize firstly, large molecular substances volatilize later, the proportion of the formula at the later stage is easy to unbalance seriously, the trapping effect is reduced, and meanwhile, the lasting period is.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the problem that the current monochamus alternatus lures the core to trap the effect poor, the validity period is short, providing a monochamus alternatus lures the core, adopts capsule shell encapsulation gathering pheromone, has better slowly-releasing effect to the efficiency is traped in lasting performance.

Further, the utility model discloses the utilization will contain the cotton core body of gathering pheromone capsule and place in the plastic tubing and fix, design the opening on the plastic tubing to make gathering pheromone release through the opening of plastic tubing, have the advantage of stable release.
