Description

Monochamus alternatus imago trap

Technical field:

The present invention relates to a kind of Monochamus alternatus imago trap, belong to the control of insect technical field.

Background technology:

Monochamus alternatus (Monochamus alternatus Hope) has another name called Monochamus alternatus Hope, is a kind of important pests in the forestry.The direct harm that can cause pine tree: its weak pine of larva harm growth potential or be on the verge of phloem and the xylem of pine, destroy, cut off conducting tissue, influence moisture, nutrient transport, influence pine tree and grow, thereby cause pine tree in blocks withered; Adult then forms wound on the spray of extra-nutrition phase in healthy pine tree, make it withered.Indirect hazard then is: propagate pine nematode (Bursaphe lenchus xylophilus), pine wood nematode then is the arch-criminal of deadly pine tree.Pine tree infects pine wood nematode after being ill, causes resin duct parenchyma cell and epithelial destruction and death, causes the plant dehydration, and transpiration reduces, and the resin secretion sharply reduces and stops.This pine nematode is international, domestic quarantine nematodes, the pine that is injured can not be as economic timber, thereby can cause enormous economic loss to forest resourceies, and the forest zone ecotope of being injured, natural landscape be seriously damaged all, more China's pine forest resource constituted a serious threat.Monochamus alternatus is caused harm to pine wood nematode and has been played the key effect of carrying, propagate, assisting to invade pine tree in the process, therefore, control pine nematode and spread, and key is to control the population quantity of pine nematode communication media Monochamus alternatus at woodland.

But prevent and treat in the process because Monochamus alternatus is a trunk borer actual, larva survives the winter in the xylem of host's limb, has increased difficulty to preventing and controlling.The chemical prevention and control method of traditional punching injection pesticide control larva has certain effect, but is difficult to large-area applications.The control adult of spraying insecticide can force down insect density to a certain extent, but the adult eclosion time is inconsistent, and duration is long, and the movable egg-laying period of adult individuality is not long, and spray date is difficult to hold; If a large amount of spray medicines are killed natural enemies contaminated environment also not only; And the Monochamus alternatus emergence Sheng phase on the occasion of rainy season, medicament is washed away by the washing of rainwater often, causes the lasting period short.Biological control is restricted by the biological property of ecological factor such as geographical environment, weather and Monochamus alternatus itself but, and control cost height, and effect is undesirable.

In recent years, the adult trapping methods that adopt in the Monochamus alternatus control more.The adult trapping is to adopt a kind of method of trapper in conjunction with attractant trapping adult.At present, the invention of many longicorn killing trapping devices is arranged, as " Longicorn trap " (number of patent application: 99253657.X), " woodland assembled longicorn catcher " (number of patent application: 200720026597.2), " barrel-shaped trapper " (number of patent application: 200720305637.7), and " Monochamus alternatus Hope trapper " (number of patent application: 03228655.4).Though existing these trapping devices that are used for Monochamus alternatus can be caught Monochamus alternatus imago substantially, but still there is the deficiency that attractant effect is not good enough, be difficult for monitoring Monochamus alternatus trapping situation.

Summary of the invention:

The objective of the invention is to overcome the deficiency of prior art, and provide a kind of simple in structure, cost is low, the good Monochamus alternatus imago trap of attractant effect.

A kind of Monochamus alternatus imago trap of the present invention, comprise cylindrical body (3), funnel-form connect worm device (6), with connect the collection worm bottle (7) that worm device (6) lower end is connected, wherein:

A. brown cylindrical body (3) upper end is provided with symmetry on the lid (2) that can open, the outer surface and has the retaining worm wing plate (5) that is welded with three brown that are mutually 120 ° on attractant sending-out hole (4) that the dozens of diameter is 2 ~ 3mm, the lateral surface, each bolt of wing plate (5) top has an iron wire and integrated a branch of hook (1) that becomes, wing plate (5) lower end is connecing on the worm device (6) with the screw riveting, and wing plate (5) is longer than main body (3) 5 ~ 10cm;

B. the upper opening diameter that connects worm device (6) of inner wall smooth is greater than main body (3) diameter 8 ~ 12cm;

C. the bottom with the collection worm bottle (7) that connects the inner wall smooth that worm device (6) is connected has several leaking holes (8), and collection worm bottle (7) adopts the light transmission good material of market sale to make.

The present invention compared with prior art, have simple in structure, cost is low, long service life, the good advantage of attractant effect.The present invention combines practicality with effective attractant, can trap Monochamus alternatus imago expeditiously, can also lure flatheaded borer, kowtow the forestry pests of the helmet, weevil, bark beetle, chafer and other longicorns.

Description of drawings:

Accompanying drawing is a structural representation of the present invention.

Embodiment:

The invention will be further described below in conjunction with accompanying drawing embodiment.

Monochamus alternatus imago trap of the present invention, comprise cylindrical body (3), funnel-form connect worm device (6), connect worm device (6) lower end be connected with the collection worm bottle (7), wherein:

A. brown cylindrical body (3) upper end be provided with symmetry on the lid (2) that can open, the outer surface have 20 or 30 diameters be 2 or the attractant sending-out hole (4) of 3mm, lateral surface on be welded with the retaining worm wing plate (5) of three brown that are mutually 120 °, each bolt of wing plate (5) top has an iron wire and integrated a branch of hook (1) that becomes, wing plate (5) lower end is connecing on the worm device (6) with the screw riveting, and wing plate (5) is longer than main body (3) 5 or 10cm;

B. the upper opening diameter that connects worm device (6) of inner wall smooth is greater than main body (3) diameter 8 or 12cm,

C. the bottom with the collection worm bottle (7) that connects the inner wall smooth that worm device (6) is connected has 5 or 10 leaking holes (8), and collection worm bottle (7) adopts the light transmission good material of market sale to make.

Using method is as follows:

Step 1: the lid (2) on the main body (3) is opened, the attractant bottle is put into main body (3), then cover lid (2).

Step 2: utilize the hook (1) on the retaining worm wing plate (5) that trapper is suspended on the spacious ventilation of woodland, hang on the iron wire between two trees, the lower end is 2～3m overhead, and each trapper is at a distance of more than the 50m.

Step 3: trapper hangs over woodland, attractant distributes in air by sending-out hole (4), the Monochamus alternatus imago of woodland is subjected to luring of attractant can flight seek odor source,, position and select to fly to trapper its influence by brown, column type trapper thereby help Monochamus alternatus imago.The Monochamus alternatus imago that flies to trapper can clash into retaining worm wing plate (5) and column type main body (3) and fall into and connect worm device (6).Because connecing worm device (6) inner wall smooth causes the rapid landing of Monochamus alternatus imago to collecting in the worm bottle (7).Collection worm bottle (7) inner wall smooth makes the adult of traping to escape.

Monochamus alternatus imago trap of the present invention also can be used for the monitoring of woodland Monochamus alternatus generation and the control of insect density.

Practical application shows: Monochamus alternatus imago trap of the present invention reaches designing requirement fully.
