Description

Method for preventing and treating red mites of poultry
Technical Field
The invention belongs to the field of poultry red mite resistance, and particularly relates to a method for preventing and treating poultry red mite.
Background
The red mites of poultry are also called dermanyssus gallinae, red chicken mites, perching mites, chicken mites and the like, are serious poultry ectoparasitic pests and are potential pathogenic vectors. The red mites usually climb to the chicken body at night to suck blood, and hide various gaps and cracks in the daytime; the red mites are widely prevalent in the world, and the prevalence rate is as high as 90%; the chickens suffering from the red mites are uneasy to appear, the feather pecking and anus pecking conditions are increased, good rest cannot be obtained, the sick chickens are emaciated and anaemic, the feed consumption is increased, the laying rate is reduced, and the death and culling rate is increased; and the red mites are the transmission media of various diseases at the same time, so that the harm is huge.
At present, red mites appear in chicken farms mainly by spraying pyrethrin or organic phosphorus and other chemicals, and the chemicals such as deltamethrin, cypermethrin and the like belong to highly toxic pesticides. However, the red mites have serious drug resistance to the pyrethrins, the dosage is not easy to control, the chickens are easy to be poisoned, the pesticide residues on eggs are heavy, even if the pesticide is sprayed, the red mites can be killed by touching the eggs by spraying the pesticide on the bodies of the chickens, and gaps are reserved in the chicken wings and wall seams and are difficult to spray in place, so that the effect of killing the red mites is poor.
In view of the above problems, it has also been proposed to kill red mites with active chemical disinfectant drugs, for example, chinese patent CN109221111A, which discloses a drug for treating poultry lice, the drug is prepared from the following raw materials in percentage by weight: 4% (C9-11 ethanol +8 mol ethylene oxide), 4.5% (quaternary ammonium compounds or dimethylbenzyl ammonium chloride or chloride), 3% didecyl dimethyl ammonium chloride, 0.9% cocoimido oxime glycinate, 1.5% N- (3-aminopropyl) -N-dodecyl-1, 3-propanediamine, 0.8% sodium carbonate, 0.02% 1, 2-benzisothiazol-3 (2H) -one, 6% (N-methyl glycine or N-methyl imino acetic acid or trisodium nitrilotriacetate), 0.3% lavender essence, water 78.98%. However, although the patent may achieve a good effect of killing red mites, the chemical substances used in the patent contain a large amount of halogen elements and are high in cost, which is not beneficial to large-scale application, and the application of a large amount of halogen elements can cause harm to the environment.
Currently, means for killing red mites by using conventional mite-killing essential oils or plant extracts are also proposed, for example, report 1, formula of essential oil: 5 drops of the eucalyptus essential oil, the tea tree essential oil and the rosemary essential oil are respectively added into mopping water to clean the floor, so that mites can be eliminated; also as reported 2, essential oil formulation: 5 drops of tea tree essential oil and lavender essential oil are respectively dropped on a paper towel (or a cotton ball) and placed in a wardrobe to remove mites; also, as reported in report 3, tea tree essential oil, lavender essential oil, eucalyptus essential oil were mixed with 5 drops each and dropped in warm water, and the bedding was immersed and washed to remove mites; also as reported in report 4, essential oil formulation: the eucalyptus essential oil is 10 drops, the rosemary essential oil is 10 drops, the lemon essential oil is 20 drops and the tea tree essential oil is 10 drops, and the eucalyptus essential oil and the alcohol are mixed and then sprayed to every corner of a room for mite removal; for another example, chinese patent CN107519072A discloses a formula of mite-killing essential oil, which comprises the following components in parts by weight: 35-45 parts of almond oil, 25-35 parts of tea tree essential oil, 10-15 parts of pure cinnamomum camphora leaf oil, 4-8 parts of cinnamon oil, 4-8 parts of anise oil, 4-8 parts of geranium oil, 4-8 parts of cinnamomum camphora tincture and 2-5 parts of ethanol; therefore, some essential oils or formulas are proposed to be used for killing the red mites on chicken flocks, but the effect is not ideal in practical application, and the essential oils or formulas are preliminarily considered to have a good effect on killing the poultry red mites because the red mites have extremely strong fertility and are spread very quickly and the living environment of the red mites is complex and variable.
Therefore, a means of killing red mites on poultry, especially chicken groups, is urgently sought.

Essentially as in example 4, all essential oil components were replaced with equal amounts of cinnamaldehyde.
EXAMPLE 5 in vitro inhibitory Effect of the plant essential oil compositions of examples 1 to 4 and comparative examples 1 to 2 on Red mite
The test method comprises the following steps:
microcapsule form solid first plant essential oil composition anti-red mite test method: weighing 0.2g of the first plant essential oil composition in a solid state in a microcapsule form into a culture dish, adding about 50 red mites, covering the culture dish with a lid, and sealing the periphery with a sealing film; the death of the red mites was observed under a stereoscope and the time to death and mortality of the red mites were recorded.
The liquid second plant essential oil composition anti-red mite test method comprises the following steps: respectively weighing 1g of the liquid second plant essential oil composition, dripping into a glass bottle with a plug, diluting according to the proportion of 1:30 and 1:60 to water, uniformly adding about 50 red mites into a culture dish, spraying 0.4g of diluted liquid essential oil onto the red mites in the culture dish by using a micro sprayer, and observing and recording the death condition of the red mites under a stereoscope.
Test results
Table 1 solid first plant essential oil composition in microcapsule form%
Figure BDA0002152558730000071
As shown in Table 1, the plant essential oil composition of the embodiment 1-2 can kill more than 80% of red mites within 30min, and can kill all red mites within 60min, which indicates that the effect of killing the red mites is good; whereas the effect of comparative example 1 is significantly reduced.
Table 2 liquid second plant essential oil composition has a red mite inhibitory effect%
Figure BDA0002152558730000081
As can be seen from Table 2, the concentration of the essential oil which causes half of the red mites to die within 1 hour was judged as the appropriate dilution ratio. The liquid second plant essential oil composition is suitably diluted at a ratio of 1:60, and the effect of killing red mites of comparative examples 2 and 3 is remarkably reduced. In the case of very serious red mites, the dilution ratio of the essential oil can be properly reduced.
Example 6 selection of a certain hen farm in Henan where red mites occur for animal testing
Test animals and groups
Test group 1: the chickens were fed 150g/t of the solid first plant essential oil composition in microcapsule form of example 1 in a cocktail of chickens, the liquid second plant essential oil composition according to example 3: water was sprayed at a 1:60 dilution.
Test group 2: the chickens were fed 150g/t of the solid first plant essential oil composition in microcapsule form according to example 2 in a cocktail of chickens, the liquid second plant essential oil composition according to example 4: water was sprayed at a 1:60 dilution.
Control group 1: chickens were fed to a red mite broiler house with only 150g/t of the solid first plant essential oil composition in microcapsule form of example 2 in admixture with feed.
Control group 2: only the liquid second plant essential oil composition of example 4 was used for the red mite severe coop: water was sprayed at a 1:60 dilution.

2.1 Effect of Red mite Severe hen houses on Red mite treatment modalities
Table 4 effect of red mite on red mites by different methods in a severe chicken coop
Figure BDA0002152558730000092
As can be seen from Table 4, the red mites all died 8 days after the feed was dressed with the essential oil spray +150ppm essential oil of the invention. The red mites die little by little at the beginning, the red mites are improved in two or three days, the red mites die basically in 5 to 7 days, all the red mites are killed in 8 days, and meanwhile, chickens have no respiratory symptoms and grow normally. The acaricidal effect of the essential oil spray and 150ppm essential oil mixed material in the test group 2 is slightly better than that in the test group 1.
The chicken fed with the control group 1 mixed with the feed can completely kill the red mites after a long using time, but the killing period is obviously prolonged compared with that of the test groups 1-2.
The control group 2 can completely kill red mites after the essential oil spray is used for a longer time, but the killing period is obviously longer than that of the test groups 1-2 and is shorter than that of the control group 1.
The control group 3 adopting the essential oil spray and the essential oil mixing material of the comparative example can completely kill the red mites after long-time use, but the killing period is obviously prolonged compared with the test group 1-2, but the killing period is shorter than that of the control group 1 and is longer than that of the control group 2.
