Description

Portable device for trapping and releasing bacteria for biological control pests

technical field

The utility model relates to a trapping device for preventing and controlling forest pests.

Background technique

The red beetle is one of the major foreign pests that have invaded China in recent years. After entering China with the timber trade ⁱⁿ the last century, it broke out in Shanxi in 1999 and caused a disaster in 2000. 10,000 hm ² , involving 54 counties (districts) in 8 prefectures and cities in Shanxi Province, causing 3.516 million pinus tabulaeformis over 20 years old to die; in the autumn of 1999, large-scale disasters were also found in Hebei and Henan provinces. By the beginning of 2000, a total of 520,000 hm ² of disasters had occurred in the three provinces, and more than 6 million Pinus tabulaeformis died. In 2001, the pest was found in Yan'an, Shaanxi and other places, showing a serious spread, seriously endangering the ecological environment and the environment of the invaded areas. The safety of wild animals and plants causes huge economic losses.

At present, the forest control methods for the red beetle mainly focus on chemical control such as tree root irrigation, tree trunk spraying, tree trunk injection or poisonous swab, tying plastic cloth and aluminum phosphide airtight fumigation, physical control such as strengthening logging management , biological control such as the release of natural enemies of the wax armor, the use of plant attractants to trap and kill adults and other methods. But all there is certain defect in these methods: the cost of chemical control is high, pollution is big, consumes manpower; It is greatly affected by the climate, has a short action time, and is difficult to control in the forest, so the control effect is not ideal. All these methods cannot achieve both deworming and long-term control while ensuring eco-friendliness.

Simultaneously, in the control of using plant attractants to trap and kill the red beetle, all traps are made of hard materials (polyethylene board or metal), the cost of control is high, and they are easily damaged when used in the forest; It is a cylinder with a height of nearly 1m, and it cannot be disassembled at most, so it is very inconvenient to transport; when used in the forest, it will take a lot of energy to carry such a trap to the depths of the forest.

Contents of the invention

In order to achieve the sustainable control of the red beetle, prevent environmental pollution, and reduce the control cost, the utility model provides a portable device for trapping and releasing bacteria for biological control pests.

The specific structural design scheme is as follows:

The portable device for trapping and releasing bacteria for biological control pests includes two leaky basins, the two leaky basins overlap up and down, and the four corners are connected in series through hanging ropes. The top cover is connected in series with the suspension rope, and the base is connected in series under the lower drain basin through the suspension rope; a hook is arranged on the top of the top cover, and non-woven bacterial strips are placed in the two drain basins.

The drain basin is a square basin with a large top and a small bottom. The basin body is a metal keel frame, and the four walls of the basin body are wrapped with polyethylene cloth. The height of the basin body is 100-120 mm; the bottom of the basin is a wire mesh; The grid area is 1 cm.

The base is plate-shaped with a slightly convex middle part.

The beneficial technical effects of the utility model are that the device for trapping and releasing bacteria is easy to carry and transport, it is not easy to be damaged when placed in the forest, it can be reused, the structure design is reasonable, the operation is simple, the cost of prevention and control is low, and it consumes less manpower. It protects the ecological environment, has irreplaceable advantages of other methods, and has a very broad application prospect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Example:

Referring to Fig. 1, the portable device for trapping and releasing bacteria for biological control pests includes a top cover 1, two drain basins 2 and a base 3, and the two drain basins 2 overlap up and down, and the four corners are connected in series through hanging ropes 4; the drain basin 2 is the upper Large and small square pots, the pot body is a metal keel frame, the four walls of the pot body are wrapped with polyethylene cloth, the height of the pot body is 100 mm; the bottom of the pot is a wire grid 5; the unit grid area of the wire grid 5 is 1 cm. The top of the upper drain basin is connected in series with the top cover 1 through a sling, and a hook is installed on the top of the top cover; the bottom of the lower drain basin is connected in series with the base 3 through a sling 4, the base 3 is plate-shaped, and the middle part is slightly convex. The slow-release bottles are fixedly placed in the middle of the two drain basins, and non-woven bacterial strips are fixedly placed around the slow-release bottles by iron clips. The non-woven bacterial strip cannot be covered with barbed wire, so as to leave a gap to facilitate insects to leak to the lower layer.

Working principle: The red fat beetle is a borer damage. After its larvae develop into adults, they will drill out of the borer tunnel and fly in the forest to find new host trees. Because the red beetle is sensitive to the pheromones of other individuals in the species (causing the aggregation of males and females or the repelling effect between individuals) and the volatile substances of the host, the utility model combines the plant attractant of the red beetle with the nonwoven beauveria bassiana The cloth bacteria strips are designed together, firstly, the migratory red beetle adults are lured to fall on the bottom plate of the upper leaky basin of the trapping device, and contact with the pre-placed non-woven fabric strips, so that they can actively or passively Contaminated with Beauveria bassiana spores, it leaks to the lower drain basin through the wire grid, and then leaks through the wire grid to the base after contacting Beauveria bassiana, and then flies out from the base; then the red beetle beetle contaminated with Beauveria bassiana spores passes through The behavior of migrating to find hosts will spread the Beauveria bassiana spores to other places in the forest, expanding the amount of bacteria in the forest; the third step is to spread the Beauveria bassiana spores through the behaviors of attracting, gathering, mating, and laying eggs among individuals of the red beetle. It directly infects other individuals of the red beetle beetle, causing infection; finally, an epidemic is formed in the forest, and the infected worms provide a source of bacteria for the Beauveria bassiana pest control in the second year.

Operation process: From May to November every year, fix the slow-release bottle containing the lure in the middle of the drain basin, and clamp the non-woven bacterial strips produced by the highly toxic strain of Beauveria bassiana obtained through the screening in the slow-release bottle Just in the surrounding drain basin.
