Background
With the rapid development of the forestry and fruit industry in China and the continuous enhancement of urban landscaping, forest pests are gradually increased, and harm is caused to a plurality of forest and fruits.
Trunk borers are one of the main pests of trees, and trunk borers refer to the pests boring branches and trunks, eat phloem and xylem, and are mainly trunk borers harmful to garden plants: various longicorn, gerbera, weevil, bark beetle, etc. Most of the pests live in denuded life in adult stage, and other insect states live in concealed life in phloem and xylem. The damage of pests is not easy to be found at the initial stage, and once obvious harmful symptoms appear, the control opportunity is lost. Living in the tissue, is slightly influenced by the environment, is relatively difficult to control, and eats phloem, xylem and the like, influences the conducting tissues of plants and is seriously damaged.
There are some pests in gardens that have the habit of crawling down trees for overwintering in autumn, crawling up trees for feeding in spring, crawling down trees for overwintering in growing season, or feeding in summer, such as spring loopers, fall moths, pine caterpillars, and the like. Because the trunk is a necessary way for the pests in a specific time period, the population density can be effectively monitored and the pests can be prevented and controlled by adopting a certain blocking trapping mode in the specific time period.
Because the harm of trunk borers and pests on upper trees and lower trees is increased continuously, the concealment or the transferability of the trunk borers and the pests on the upper trees and the lower trees is a difficult point for preventing and controlling the trunk borers and the pests, a pest trapping net is developed, and the trunk borers and the pests are blocked and trapped in specific activity periods and areas of forest and fruit pests, so that the healthy growth of forest trees is protected, the blind use of pesticide is reduced, and the ecological environment is protected.
SUMMERY OF THE UTILITY MODEL
The utility model discloses mainly be to above problem, provide a pest and catch net to prevent and treat stem borer class pest or the harm of upper and lower tree habit pest effectively, and play certain monitoring effect. The capture net is simple in structure, convenient to operate and timely and effective. The method is mainly characterized in that a capturing net is arranged on a trunk at the early stage of imago, so that pests on roots and the trunk are prevented from flying out or crawling on a tree or attracting pests in a certain distance, the pests are captured, mating reproduction is reduced, and pest density is effectively controlled.
In order to solve the technical key points and the difficulty of prevention and control, the utility model provides a pest catching net, which comprises a net body, a fixing device, attachments and the like.
Furthermore, the net body is of a net structure, the size and the length can be adjusted, and the pore size can be adjusted according to the sizes of different individual pests;
furthermore, the net body is mostly woven fabric or knitted fabric, and the material is synthetic resin, polyethylene, polypropylene, or degradable material, such as polylactic acid, pulp, starch, polyvinyl alcohol, polycaprolactone, poly-3-hydroxybutyrate, cellulose acetate, polybutylene succinate, polyhydroxyalkanoate, and the like;
further, the net body is only wrapped on the trunk, or is covered and wrapped from the root to a certain height on the trunk;
further, the net body is wrapped on the trunk, the foot characteristics of the pests are combined, and the net body hooks the feet of the pests on the net to trap the pests. Pests are prevented from escaping to the forest from eclosion holes on the trunk, or pests going up and down the tree are prevented from climbing to the trunk and the branch tips, or external pests are attracted by means of net body attachments, and the pests are trapped by the net body;
furthermore, the bottom of the net body is either wound around the trunk or is buried in soil around the root of the tree and fixed after being stretched and flattened;
further, the fixing device is divided into an upper fixing device, a lower fixing device and a side fixing device;
further, the net body is fixed on the upper part of the trunk by the upper end fixing device, so that pests getting on the tree are prevented from harming upwards, and the net body is prevented from falling off; the lower end fixing device is installed and used according to the situation and mainly aims to prevent pests from escaping;
furthermore, the upper end fixing device and the lower end fixing device need to have certain elasticity, the length of the upper end fixing device and the lower end fixing device can be adjusted according to the thickness of a trunk, and the two ends of the upper end fixing device and the lower end fixing device are fixed by manual binding, magic tape, self-locking ties and the like;
furthermore, the side fixing device can completely wrap the net body on the trunk so as to prevent pests from escaping due to gaps;
furthermore, the side fixing device adopts a bonding device in various forms such as double-sided tape, magic tape, buckle and the like for fixing;
further, the attachment can be selectively added or not according to the type and the application of the captured pests;
furthermore, the attachment can be selected from environment-friendly medicaments, insect pheromones and the like, so that certain attracting and killing effects on pests are achieved. After the contact insecticide is selected for coating, pests are killed after contacting with the contact insecticide, and insect sex pheromones, aggregation pheromones and the like can also be selected, so that a certain attracting effect is achieved on the pests, and the capturing efficiency is improved;
furthermore, the attachment can also contain a certain synergist, so that the utilization rate of the pesticide and the pest capturing rate can be effectively improved;
furthermore, the attachment can be coated on the surface of the net body, mixed in the net body or attached outside the net body in a lure mode according to the characteristics of the medicament and the like. The connecting part of the net structure is coated with particle attachments with certain size, or the attachments are mixed in the net body by soaking and other modes, or the outer side of the net body is attached with the specific lure core.
Preferably, the specification and the size of the net body are 5-200cm in length and 60-120cm in width;
preferably, the pore size of the net body can be 3-10 mm.
The utility model provides a net is caught to pest, its simple structure, convenient operation, reasonable in design, convenient high efficiency. The net body material, the aperture size, the preparation of the fixing device, the presence or absence of attachments and the types have strong operability, and the net body is effective to trunk-boring pests and upper and lower tree habit pests. Aiming at different users, the operation is simple and easy to understand, and the product can be effectively utilized. The product can prevent sun and rain, can be reused, saves cost, saves time and labor, does not produce pesticide residue and pollution, is a green prevention and control product, and is convenient to popularize.
