Embodiment 1

[0041] The compound is 0.1% by mass, the heating transpiration accelerator A is 0.2% by mass, and the mosquito repellent incense base material such as pyrethrum extract meal powder, wood powder, starch, etc. is 99.7% by mass, and they are uniformly mixed, and then add the pigment and antiseptic The water of agent, with known method, obtains the tropical infectious disease vector mosquito control mosquito repellent incense stick of the present invention.

Embodiment 2

[0043] Make this compound 0.2 mass %, heating transpiration accelerator A is 0.5 mass %, 2,6-di-tert-butyl-4-methylphenol is 0.1 mass %, and make coconut shell powder, wood powder, Phoebe powder, The mosquito repellent incense base material such as starch is 99.2% by mass, uniformly mixed, and then water containing a preservative is added, and the mosquito repellent incense stick for controlling mosquitoes of tropical infectious diseases of the present invention is obtained by a known method.

Embodiment 3

[0045] [Measurement of the volatilization rate of active ingredients when incense sticks are smoked]

[0046] On the upper part of the exhaust bell with an internal volume of about 1.5 liters, two traps for trapping volatile matter (inner diameter 25 mm, length 10 cm) stuffed with about 6 g of silica gel were connected in series to a vacuum pump. Set 2g of mosquito repellent incense sticks for testing on the line incense holder, and place it in the center of the bottom surface of the exhaust bell. After ignition, pump air at a rate of 8 liters per minute, and take samples of volatile substances. After the fumigation is finished, the volatile substances trapped in the trap and the volatile substances attached to the inside of the exhaust bell are washed away, and the amount of the recovered effective components is analyzed by gas chromatography. The active ingredient volatilization rate was calculated from the recovered amount relative to the theoretical active ingredient amoun...

Abstract

The invention provides a mosquito repellent for preventing infectious disease medium mosquito, with excellent effect for infectious disease medium mosquito such as Aedes aegypti, Culex fatigans, anopheles and so on, and excellent safety to the human ans domestic animal and low cost. The mosquito repellent comprises 0.1-0.5 weight% of (S)-2-methyl-4-oxy-3-(2-allylene)-2-cyclopentenyl(1R)-antiform-chrysanthemum monocarboxylate, preferably used as heat and evapotranspiration accelerant, ralative to the active ingredient, comprising 1.0-5.0 times of N-(2-ethylhexyl)-double ring-[2,2,1]-age-5-olefin-2,3-dicarboximide.

Description

technical field [0001] The invention relates to a mosquito repellent incense stick for controlling mosquitoes which are vectors of tropical infectious diseases. Background technique [0002] There are many kinds of mosquitoes in the world. They not only bite and suck human blood, but also cause serious harm through infectious diseases. For example, it is known that in tropical regions such as Southeast Asia and Africa, malaria is mediated by Anopheles mosquitoes, dengue fever is mediated by Aedes aegypti and Aedes albopictus, yellow fever is mediated by Aedes aegypti, and filariasis is known to cause fatigue. Culex mosquitoes are the vector. In the absence of proper vaccines today, as a way to prevent these tropical infectious diseases, the most important thing is not to be bitten by mosquitoes, especially in open dwellings, it is most suitable to use mosquito repellent coils. Mosquito nets are impregnated with pyrethroids and used, but they can only be used during bedtime...
