A method and apparatus for removing of Varroa Mites from Honeybees as the Honeybee enter and exit the hive entrance.

A frame and comb foundation and method for controlling Varroa mites in a honeybee hive. In a first embodiment the invention is comprised of half portions of the frame and comb foundation in combination with a power supply, heating element, electronic control unit (ECU), temperature sensor and an optional diagnostic system. The ECU which may be mounted on the frame and comb foundation or, in a separate enclosure is comprised of a micro-controller and other circuitry. The temperature sensor is mounted adjacent to the heating unit. The power supply may mobile or stationary, such as a battery or line current.In a second embodiment, the frame and comb foundation is interconnected with similar frame and comb foundations in multiple hives that include individual ECU's and temperature sensors and individual wireless electronic communication systems, a single power source and individual heating elements. The multiple temperature sensors are mounted adjacent to the heating elements. The ECU's are mounted on the frame and comb foundations or in separate enclosures. The ECU's are comprised of logic circuits or micro-controllers and other circuitry. The power source may be a mobile or stationary source such as a battery.

An isolated nucleic acid agent is disclosed comprising a nucleic acid sequence which downregulates expression of a gene product of a Varroa destructor mite. Compositions comprising same and uses thereof are also disclosed.

The invention concerns a composition for the treatment of varroa mite infestations in honeybee colonies, comprising a base layer and an active layer, wherein the active layer comprises an effective amount of an acaricidal compound.

This application provides and discloses anti-parasitic, anti-pest or insecticidal nucleic acid molecules and their calmodulin target genes for the control of arthropod parasites and pests. In particular, this application provides and discloses insecticidal nucleic acid molecules that target Varroa calmodulin gene sequences. This application further provides methods and compositions for the control and treatment of parasites and pests in Apis mellifera (honey bee) hives.

The invention relates to a device for combating the varroa mite in a bee brood, comprising at least one middle wall that can be inserted in particular into a beehive and that is provided with brood cells for female bees, the device having an electrical heating device that has a resistance heating element embedded in the middle wall and a control device connected to the latter which is designed such that an automatically running heating process can be initiated with a temporally pre-determined heat-up phase that lasts until a temperature of 39° C. to 45° C., preferably 39° C. to 42° C., is reached at the bottom of the brood cells in the region of the resistance heating element and then with a subsequent phase of maintaining this temperature for a predetermined period of time.

Nucleic acid agents for reducing or removing infestations of the Varroa destructor mite are described. Compositions comprising the nucleic acid agents and methods for controlling mite infestations using the nucleic acid agents and compositions are also disclosed.

The manufacturing method of the varroa mite biological trap disclosed by the invention comprises: 1) making the varroa mite biological trap unit module; 2) building a house, installing the varroa mite biological trap unit module in a standard nest frame , at least two Varroa mite biological trap unit modules are installed in the standard nest frame; 3) bait is cast; 4) After the Varroa mite biological trap is made, it is taken out and placed in each bee colony box to trap and kill Varroa mite. The ambush method of the varroa mite biological trap of the present invention includes: 1) determining the ambush location according to requirements; 2) the ambush time; 3) the ambush period.

The invention discloses a varroa mite toxic protein, its coding gene and application. The present invention clones a new coding gene VMP of a new Varroa mite poisonous protein VMP from the genome of the Varroa mite, and its expression product VMP has a toxic effect on honeybees, so the Varroa mite of the present invention can be The varroa mite poisonous protein VMP and its coding gene are applied to the preparation of bee-killing medicine. The invention also creates conditions for the basic scientific research on the mechanism of the Varroa dessica harming honeybees.

In particular, this application provides and discloses insecticidal nucleic acid molecules that target Varroa calmodulin gene sequences. This application further provides methods and compositions for the control and treatment of parasites and pests in Apis mellifera (honey bee) hives.

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.

The invention relates to an antibacterial and detackifying agent, a preparation method thereof and a method for improving the hatching rate of artificial breeding of crocodile vacheronii by using the antibacterial and detackifying agent, belonging to the technical field of aquaculture. In order to solve the problem of low hatching rate and low survival rate of crocodile vacheronii artificial breeding, the invention provides a kind of antibacterial debonding agent, which mainly consists of an adsorptive carrier and an antibacterial component loaded on the carrier. The antibacterial The ingredients are mainly composed of gallnut, skullcap, flavescens, honeysuckle, forsythia and calamus. The method for improving the hatching rate of artificial breeding of crocodile vacheronii by using the antibacterial and debonding agent of the invention includes artificial fertilization, debonding of fertilized eggs, treatment of saprolegnia prevention, hatching and seedling raising. The antibacterial and debonding micron-level adsorptive carrier of the present invention has a good debonding effect, which enables the fertilized eggs to be separated from each other and improves the hatching rate of the fertilized eggs; the active ingredients of the traditional Chinese medicine loaded on the adsorptive carrier can inhibit Saprolegnia spores and other bacteria The invasion of saprolegniasis is prevented, and the survival rate of fry is improved.
