Description

Fumigation agent for bee pest control {THE FUMIGANT TO CONTROL HONEYBEE PEST AND DISEASES}

The present invention relates to a fumigation agent for controlling bee pests such as bee mite, Chinese barley mite, chalk disease, and more specifically, it is mainly composed of organic acids and plant essential oils that have a control effect through steam and coated beeswax with a fumigation catalyst. It relates to a fumigation tablet.

Honeybee mites (baro-adstructors) are a globally distributed and parasitic pest that seriously damages the beekeeper industry and sucks body fluids while parasitic on bees' larvae, pupa and adults. Because of this, honeybees do not develop normally and cannot function normally, and if the outbreak is severe, the forces of the Bong-gun are greatly weakened and lead to the lung-gun. Resistant organisms are becoming increasingly difficult due to the emergence of resistant organisms to organic synthetic acaricides and are the most threat to bees in production beekeeping as well as in Korea. Bee mites have been chronically parasitic to domestic honey bees since they were confirmed in the 1960s. With the Chinese mites introduced from foreign countries in the mid 1990s, bee mites are the most damaging to domestic beekeepers.

The pathogen of asymptomatic bacteria (ascorera apis), a chronic fungal disease in the bee bong, invades the larvae's mouth in the form of spores, germinates in the intestine, and kills the larvae by proliferating mycelia. It is a disease that is completely difficult to control since it remains pathogenic for 15 to 15 years.

Prior similar inventions related to bee pest control agents have been developed for the synthesis of feed bee mite control drug chimazole, sustained-release formulations of vegetable oils, ie gels, methods of disease suppression through polymer matrices. In addition, an electric heated bee mite extinguisher has been developed to control the vaporization of oxalic acid powder, a commercial chemical raw material, and to be vaporized.It is difficult to process the correct amount during use, and the user may be exposed to the powder and strong acidic odor during handling. Is large. In addition, when the oxalic acid powder is mounted outside the beehive, the powder is vaporized in a fume at a short time, and the working user is exposed to the outflowing gas, so it is difficult to expect a safe and effective control effect by the quantitative treatment.

The present invention is mainly made of organic essential oils such as oxalic acid and plant essential oils such as thymol and the like, and added to the fumigation rate-reducing agent and the fumigation catalyst to improve the efficiency and safety of bee pest control. Unlike the previous conventional fumigation methods, the composition is characterized as a quantified and standardized fumigation agent.
