Chicken mites (Dermanyssus gallinae, Red-mite, also known as Wagumo) are subtropical external parasites measuring 1 mm in size. They live in crevices or feces inside the chicken house and attach to chickens when it gets dark and feed on their blood. Chicken mites are not insects but spiders.

In the case of laying hen farms, the penetration rate of chicken mites is very high, ranging from 23% to a maximum of 90%. Infiltrated chicken mites not only reduce chicken egg laying rate by 10-15%, egg weight by 2.2%, and feed efficiency by 5.7%, but also cause itchiness and stress in chickens, while acting as vectors for diseases such as salmonella. do. Recently, pesticides treated to control chicken mites accumulated and remained in eggs, causing social controversy.

Chicken ticks start sucking blood as nymphs and continue to drink blood for more than a week until they become adults. They parasitize on the brood body only when sucking blood, usually for 30 to 60 minutes, and after sucking blood, they hide in the chicken house to lay eggs, digest, and reproduce. The optimal temperature for chicken mites to lay eggs is 25-30℃ and the optimal temperature for growth is 25-37℃.

Chicken mites are a problem worldwide, but there is a lack of information on how to prevent or eliminate chicken mites.

Currently, the drugs used in Korea to control chicken mites include pyrethroids such as bifenthrin and cypermethrin, carbamates such as BPM, organophosphorus pesticides, and formic acid. This is representative. In addition, there has been a recent problem due to the use of fipronil, a phenylpyrazoe product that has not been approved.

In order to quickly achieve this control effect, chemical pesticides are used, but chemical pesticides are not only expensive, pollute the soil, and have the risk of destroying the balance of the ecosystem, but also show resistance to these pesticides if sprayed continuously. Chicken mites appear rapidly, making control more difficult.

So far, various studies are in progress on physical and biological control methods for chicken mites, but the only known practical methods for controlling chicken mites using eco-friendly chemicals using natural products are ginkgo leaves, neem oil, and clove extract, so development is extremely limited. The situation is insufficient.

In addition, the conventional method of controlling chicken mites using eco-friendly chemicals is to treat the chemicals to the chicken house using methods such as spraying rather than fogging.

Karanja (Pongamia glabra) is a shrub that grows wild in India, Myanmar, Sri Lanka, and islands in the Strait of Malacca, and is used as soap, moisturizing hair and body oil, and pesticides.

It also has a moisturizing effect, so it is also used in the treatment of eczema, psoriasis, skin ulcers, and dandruff. You can use it. Carranza oil has similar effects to neem oil, but has a different scent.

Clove (Eugenia caryophyllata) is an evergreen tree belonging to the Myrtle family and is native to Indonesia. It was called clove because the dried flower buds resembled nails. Clove oil is an oil component obtained from the flower buds or leaves of the clove tree. The yield of clove oil is 17-20% for clove bud oil, about 6% for clove stem oil, and about 6% for clove oil (clove oil). clove leaf oil) is 2-3%. The main component of clove oil is eugenol, and it also contains iso-eugenol and caryophyllene. Clove not only has a good scent, but also has excellent anti-corruption, sterilizing, and insecticidal effects among fragrances.

Cinnamon is made by peeling the bark of the trunk and branches of the cinnamon tree, removing some of the cork layer, and drying it. It is yellow-brown in color. Sri Lanka accounts for 70% of the global market for cinnamon, and a lot of it is produced in South India, Sumatra, and Borneo. Cinnamon has a unique scent and tastes astringent but sweet and mucilaginous. Cinnamon contains various components. Essential oil contains 1-4% cinnamon oil, and the main component of cinnamon oil is cinnamaldehyde. Cinnamon's fragrant ingredients are known to be effective in killing house dust mites that cause allergies.

Chenopodium ambrosioides is an annual plant of the Chenopodium ambrosioides. Yangmyeong aju is a naturalized plant native to South America, and in Korea, it is naturalized throughout the entire region, centering on the Deokcheon River. The stem has many branches, has sparse hairs on the top, and is about 30 to 80 cm tall. Flowers bloom between June and October. The leaves are long, oval-lanceolate, alternate, have teeth of different sizes on the edges, and the petioles are short and have light yellow lines on the back. There are multicellular hairs on the veins, and the upper leaves are linear and without serrations. The flowers form panicles, and the bisexual flowers are large and have 5 stamens, while the unisexual flowers are small, the stamens are degenerated, and have 3 capitals. The fruit is a porpoise, and the seeds are dark brown, round, ovate, and the seedlings of Yangmyeong-Aju have a unique smell. Matrine is an alkaloid contained in about 2% of Yangmyeong root and is a highly natural insecticidal ingredient.

Neem (Azadirachta indica) has been widely used as a pest control agent in India since 4,000 years ago. The main component of neem is azadirachtin, and the components Salannin, Meliantriol, and Nimbin are also known. In particular, neem oil, whose main ingredient is azadirachtin, is effective in killing mites, mites, thrips, whiteflies, aphids, and scale insects. It has insecticidal activity that inhibits the molting of insect larvae, prolonging the larval period and interfering with feeding, so it was registered as a biological pesticide by the U.S. EPA in 1985, and was also registered as a botanical pesticide in China in 2010.

It is preferable to use a mixture of water and ethanol as an extraction solvent, and it is more preferable to use a mixture of water and ethanol at a weight ratio of 1:1 to 3.

Matrine has a synergistic effect in exterminating pests when mixed with other substances with insecticidal effects, so even when used in small amounts, it has an excellent pest extermination effect.

2. Paraffin oil

Paraffin oil is purchased and used commercially. It is advisable to purchase and use paraffin oil, which is an organically permitted substance, from an oil refinery company.

3. Spreading agent for smoke screen

Neem oil and Tween-80 (Polyoxyethylene Sorbitan Monooleate) are used as diffusion agents for smoke screens to produce smoke screen compositions.

Neem oil is an oil component extracted from the neem plant, and can be used commercially or manufactured. Preferably, it can be manufactured and used by the following method.

First, crush the neem fruit. It is desirable to extract the crushed neem fruit at least twice with ethanol at a concentration of 90% by weight or more. More preferably, the extraction is repeated three times. Neem oil powder is obtained by drying the extracted neem oil under reduced pressure. The obtained neem oil powder is dissolved in purified water and used.

It is preferable that neem oil is contained in an amount of 5 to 20% by weight and Tween-80 is contained in an amount of 5 to 10% by weight.

The smoke spreader may further contain ethanol as needed. Ethanol can increase the fluidity of the composition. When using ethanol, it is desirable to use 2 to 5% by weight of the composition.

By using a smoke spreader, smoke screen can be sprayed and chicken mites can be controlled more effectively than conventional spraying methods.

4. Smoke screen composition for chicken mite control

A mixture of paraffin oil, caranja oil, cinnamon oil, clove oil, and Yangmyeong root extract is used as active ingredients, and neem oil and Tween-80 are used as a smoke spreading agent.
