Problems solved by technology

[0003] Paederus syphilis is nocturnal, has strong phototaxis, and can secrete strong acidic venom to cause an inflammatory reaction after skin contact. Therefore, there are a large number of paederus syphilis in residential areas, which brings great benefits to people. life has brought great inconvenience
At present, the prevention and control of Paederus syringus is mainly to spray insecticides such as deltamethrin or fendina on the indoor and surrounding environment; these insecticides have relatively large toxic and side effects on the human body, and are not conducive to environmental protection

Embodiment 1

[0022] Experimental study on the avoidance of Paederus spp.

[0023] 1.1 Repellent test method: put a piece of filter paper with a diameter of 8 cm in a petri dish with a diameter of 9 cm, cut the filter paper into two halves, drip 0.5 mL of essential oil soluble in acetone on one half, and drip 0.5 mL of acetone on the other half, let it dry naturally Dry for 5 minutes, the concentration of essential oil on the filter paper is 0.1μL / cm 2 . The experiment was repeated 3 times, and the results are shown in Table 1.

Embodiment 2

[0040] Experimental Study on the Fumigation of Paederus thoracoides

[0041] Fumigation experiment method: In a small bottle with a volume of 110mL, place a filter paper with a length and width of 1cm under the bottle cap, drop 0.22μL of pure essential oil to form a concentration of 2μL / L air, and put 15 male and female shuttlecocks for each treatment Poisonous paederus, repeat 3 times. After 1, 2, 4, 6, and 8 hours of treatment, the worms were placed in the rearing environment for 24 hours, and the corrected mortality was counted. Determination of wintergreen oil LC 50 The value processing method is the same as above, the amount of dripping essential oil is set from 0.14 μL to 0.30 μL, and there are 5 concentration gradients. The experimental results are shown in Table 4.

Embodiment 3

[0046] Experimental Research on Contact Killing of Paederus syringus

[0047]Contact treatment method: drip 0.1 μL of essential oil dissolved in acetone on the pronotum of Paederus spp. at a concentration of 0.08 μL / head. After 1, 2, 4, 6, and 8 hours of treatment, they were judged as dead and placed in a feeding environment for 24 hours to observe the recovery situation and statistically correct the mortality rate. Determination of wintergreen oil LC 50 The value processing method is the same as above, drip 0.1 μL essential oil dissolved in acetone, the concentration is set from 0.060 μL / head to 0.090 μL / head, 5 concentration gradients, the experimental results are shown in Table 5.

[0048] Experimental results: Table 5. The contact activity of plant essential oils on Paederus spp.

Abstract

The invention provides plant essential oil (peppermint oil, citionella oil, eucalyptus oil, artemisia annuae oil, blumea oil, cinnamon oil, clove oil, wintergreen oil, linaloe wood oil or lemon oil). The effect of preventing and controlling the paederus fuscipes curtis is good, and the effect of repelling, suffocating or killing the paederus fuscipes curtis is very good when the concentration of the plant essential oil is very low; and moreover, the safety is high, the toxic and side effect are less, chemical harm on the environment is basically avoided, and the plant essential oil is suitable for developing a replant, a suffocating agent or a killing agent for the paederus fuscipes curtis.

Description

technical field [0001] The invention relates to the prevention and treatment of paederus syringae, in particular to the application of plant essential oils in the prevention and control of paederus syringae. Background technique [0002] The genus Paederus is a genus in the family Paederidae. There are currently more than 620 known species in the world, which are produced in all parts of the world except Antarctica. There are nearly 50 species of Paederus reported in China. Wings are the most common. The eggs, larvae, pupae and adults (all parts except the wings) of the poisonous paederus have toxins, which mainly come from the hemolymph of the worms, and both female and male (rarely) contain toxins in their bodies. The toxins of poisonous paederus are chemicals that the insect body uses to defend against foreign invasion. When a person crushes the poisonous paederus body, the skin disease of acute erythematous herpetic damage caused by body fluids contacting the human bod...
