The chicken mite (Dermanyssus gallinae, Red-mite, aka Wagumo) is a subtropical ectoparasite with a size of 1 mm. Chicken mites are arachnids, not insects.

In the case of laying hen poultry farms, the penetration rate of chicken mites ranges from 23% to 90%, which is a very high situation. Penetrating chicken mites reduce the egg laying rate by 10-15%, reduce the egg weight by 2.2%, and reduce feed efficiency by 5.7%, as well as causing itching and stress in chickens, and at the same time acting as a carrier of diseases such as salmonella. do. Recently, pesticides treated to control chicken mites accumulate and remain in eggs, causing social controversy.

Chicken mites start sucking blood from the nymph and suck blood for more than a week until adults, and only parasitize on livestock during blood sucking, usually sucking blood for 30 to 60 minutes. The optimum temperature for chicken mites to spawn is 25-30°C, and the optimum temperature for growth is 25-37°C.

Chicken mite is a worldwide problem, but information on how to prevent or relieve chicken mite is scarce.

Currently, the drugs used for controlling chicken mites in Korea are pyrethroids such as bifenthrin and cypermethrin, carbamates such as BPM, organophosphorus pesticides, and formic acid. For example. In addition, the use of non-approved phenylpyrazoe-based fipronil has been a problem recently.

Although chemical pesticides are used to achieve the control effect quickly, chemical pesticides are expensive, pollute the soil, and destroy the balance of the ecosystem. The emergence of chicken mites is occurring rapidly, making control more difficult.

So far, various studies on physical and biological control methods for chicken mites are in progress, but only the use of ginkgo leaves, neem oil, and clove extracts are known to have been put into practical use as a control method for chicken mites using eco-friendly drugs using natural products. The situation is insignificant.

In addition, the conventional chicken mite control method using an eco-friendly drug is not a smoke screen treatment, but a method such as spraying the drug in the cage.
