Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pest biological control, more particularly to a small -size pest pathogenic bacteria spreading device. BACKGROUND

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

[0003] Currently, the application of pest pathogenic bacteria relies mainly on manual operation, and the pesticides are applied to crops. At the same time, it is necessary to accurately determine the time of pest occurrence to ensure that the pathogenic bacteria can play a role in the key stage of pest growth and development. The activity of pest pathogenic bacteria after application may be affected by environmental conditions such as temperature, humidity and ultraviolet light, resulting in unstable effect.

[0004] Therefore, it is an urgent problem for those skilled in the art to provide a small -size pest pathogenic bacteria spreading device that uses a lure combined with pathogenic bacteria to attract pests and infect them, without the need for regular application, reducing the cost of manual application, and achieving the purpose of natural control.

[0079] The conical cover 3 can prevent rainwater from entering the container 1 through the pest inlet / outlet 12. At the same time, without the installation of the humidifying device 6, the drain hole 13 at the bottom of the container 1 is not blocked, allowing normal drainage and keeping the inside of the container 1 dry.

[0080] Experiment on prevention and control effect:

[0081] The dispersing device was placed in a rearing cage (60*60*40 cm) containing approximately 300 thrips. The animals were divided into groups: treatment groups 1-4.

[0082] Treatment 1: Attractant + Pest Pathogen, Examples 1 and 2;

[0083] Treatment 2: Pest pathogens were treated by removing the pest attractants from Examples 1 and 2, and no attractants were added to the attractant carrier;

[0084] Treatment 3: Attractant to remove the pest pathogens from Examples 1 and 2; the pest pathogen cloth carrier was not treated with pathogens.

[0085] Treatment 4: Blank control. The pest attractant and pest pathogens in Examples 1 and 2 were removed. The attractant carrier was not added, and the pest pathogen cloth carrier was not treated with pathogens.

[0086] Thrips mortality was examined on days 1, 2, 3, 4, and 5. The experiment was repeated three times, and the results of the indoor simulated control effect are shown in Table 1.
