Embodiment 1

[0011] Weigh 100 g of Dalbergia odorifera medicinal materials, add 300 ml of water after crushing, shake and mix, connect the volatile oil tester and reflux condenser. Heat to boiling and keep it boiling for 5 hours, and collect the volatile and condensed essential oil. Pour 0.5 ml of the essential oil of Dalbergia odorifera on a filter paper placed on the bottom of the inside of a colony box heavily infected with bee mites. The above-mentioned medicine evaporates naturally and acts on bees and bee mites.

[0012] Results: The infection rate of bee mites in adult bees before treatment was 8%, and after treatment for 3 days, the infection rate of bee mites was 2%, and there was no obvious bee poisoning reaction.

Embodiment 2

[0014] Weigh 100 g of Dalbergia odorifera medicinal materials, add 400 ml of water after crushing, shake and mix, connect the volatile oil tester and reflux condenser. Heat to boiling and keep it boiling for 5 hours, and collect the volatile and condensed essential oil. Pour 2 ml of Dalbergia odorifera essential oil on a filter paper placed on the bottom of a bee colony box heavily infected with bee mites. The above-mentioned medicine evaporates naturally and acts on bees and bee mites. The bee mite infection rate of adult bees before treatment was 8%, and after 3 days of treatment, the bee mite infection rate was 1%, and there was no obvious bee poisoning reaction.

Embodiment 3

[0016] Weigh 100 g of Dalbergia odorifera medicinal material, add 500 ml of water after crushing, shake and mix, connect the volatile oil tester and reflux condenser. Heat to boiling and keep it boiling for 5 hours, and collect the volatile and condensed essential oil. Pour 5 ml of the essential oil of Dalbergia odorifera on a filter paper placed on the bottom of a bee colony box heavily infected with bee mites. The above-mentioned medicine evaporates naturally and acts on bees and bee mites. The bee mite infection rate of adult bees before treatment was 9%, and after 3 days of treatment, the bee mite infection rate was 1%, and there was no obvious bee poisoning reaction.

Abstract

The invention provides a medicine for preventing and controlling varroa destructors. The medicine is rosewood heart wood essential oil, and is prepared according to a method for extracting volatile oil in Chinese Pharmacopoeia (2010 version). The medicine is put on filter paper of bee hives and acts on bees and the varroa destructors by natural volatilization to achieve an effect of preventing and controlling the varroa destructors of the bees, wherein the using amount of the rosewood heart wood essential oil in each bee hive is between 0.5 and 10 millimeters. A method for preventing and controlling the varroa destructors has a good effect of killing the varroa destructors and is low in toxicity on the bees, and the bees are not hurt while the varroa destructors are killed; the medicine is wide in source, easy to prepare, convenient to use, and high in volatility, and is particularly suitable for preventing and controlling the varroa destructors by fumigation.

Description

Technical field [0001] The invention belongs to the field of beekeeping, and relates to a medicine for preventing and controlling bee mites and its use in preventing and treating bee varroa mites. Background technique [0002] Varroa dissidia ( Varroa destructor Anderson & Trueman 2000, commonly known as "big bee mite") is an ectoparasitic mite of honeybees. The original host is the Oriental honeybee distributed in Asia. Western honeybees lack natural adaptability to Varroa dissidia. Due to geographical spread and inadvertent introduction, Varroa dissidia has spread from Asia to Europe, America, and Africa. Today, except for Australia, Varroa mites are not found, as long as there are bees living in the world, Varroa mites exist. Varroa mites have become the most bee pests that threaten the world's beekeeping industry. The weight of bees infected with Varroa dissidia is significantly reduced, and even developmental abnormalities. The bee colony will have a series of symptoms, su...
