Description

Technical Field

[0001] The invention relates to the technical field of pest biological control, and more particularly to a small pest pathogen spreading device. Background Art

[0002] Pest pathogens, including microorganisms such as insect pathogenic fungi, insect pathogenic bacteria and insect viruses, are a class of biological control resources with great potential. With the increasing attention paid to environmental and ecological protection worldwide, the use of these biological resources to control pests can not only effectively reduce the use of chemical pesticides and reduce environmental pollution, but also reduce the negative impact on non-target organisms. Pest pathogens can inhibit the growth and reproduction of pests by infecting the surface or body of pests, or even directly cause the death of pests, thereby controlling the number of pest populations. In addition, these pest pathogens also have the ability to self-replicate and can spread among pest populations to achieve a continuous pest control effect. More importantly, the use of pest pathogens can promote the natural balance of the ecosystem and enhance biodiversity, thus playing an important role in agricultural production and ecological protection. Therefore, researching and developing the use of insect pathogens is not only of great scientific significance, but also an effective way to achieve sustainable agricultural development and ecological protection.

[0003] At present, the application of pest pathogens mostly relies on manual operation to apply the agent to crops. At the same time, it is necessary to accurately judge the time of pest occurrence to ensure that the pathogens can play a role in the key stage of pest growth and development. The activity of pest pathogens after application may be affected by environmental conditions such as temperature, humidity and ultraviolet rays, resulting in unstable effects.

[0004] Therefore, it is an urgent problem for technical personnel in this field to provide a small pest pathogen spreading device that utilizes pest attractants combined with pathogens to attract pests and infect them, does not require regular application, reduces manual application costs, and achieves the purpose of natural control.

[0083] The cylindrical cover 2 of the embodiment 1 is replaced by a conical cover 3, wherein the conical cover 3 comprises an annular threaded portion 31, a cylindrical support 32, and a conical shielding portion 33;

[0084] The annular threaded portion 31 is in the shape of a ring and is provided with an internal thread 311 that matches the external thread 11. A cylindrical support column 32 is fixedly provided on the top of the annular threaded portion 31.

[0085] The conical shielding portion 33 is in the shape of a conical barrel, the columnar support 32 is fixedly connected to the inside of the conical barrel of the conical shielding portion 33, and a vertical line downward from the vertex of the conical shielding portion 33 passes through the center of the annular threaded portion 31;

At the same time, the moisturizing device 6 is not installed, and the drainage hole 13 at the bottom of the container 1 is not blocked, so the water can be drained normally to keep the inside of the container 1 dry.

[0089] Experiment on prevention and control effect:

[0090] The dispersion device was placed in an insect cage (60*60*40), and about 300 thrips were placed in the insect cage. Grouping, treatment groups 1-4;

[0091] Treatment 1 attractant + pest pathogens, Examples 1 and 2;

[0092] In treating pest pathogens 2, the pest attractants in Examples 1 and 2 were removed, and no attractant was added to the attractant carrier;

[0093] Treatment 3 attractant, removing the pest pathogens in Examples 1 and 2, the pest pathogen flannel carrier was not treated with pathogens;

[0094] Treatment 4 was a blank control, in which the pest attractants and pest pathogens in Examples 1 and 2 were removed, no attractant was added to the attractant carrier, and the pest pathogen flannel carrier was not treated with pathogens.

[0095] The mortality of thrips was checked after 1, 2, 3, 4 and 5 days. The experiment was repeated 3 times, and the results of indoor simulated control are shown in Table 1.

[0096] Table 1 Cumulative mortality of thrips in different treatments with the dispersing device (dry season) (%)

[0097]

[0098]

[0099] Analysis of results: The attractant + pest pathogens can achieve a thrips mortality rate of more than 95% one day after treatment. The pest pathogen treatment group is slow to take effect, but the thrips mortality rate can reach more than 78% on the 5th day, while the effect of attractant alone is not obvious.

[0100] Table 2 Cumulative mortality of thrips in different treatments with the dispersing device (high humidity season) (%)

[0101]

[0102] Analysis of results: The attractant + pest pathogens can achieve a thrips mortality rate of more than 90% one day after treatment. The pest pathogen treatment group is slow to take effect, but the thrips mortality rate can reach more than 80% on the 5th day, while the effect of using attractants alone is not obvious.
