Embodiment 1

[0041] The compound is 0.1% by mass, the heating evapotranspiration accelerator A is 0.2% by mass, and the mosquito repellent incense base material of pyrethrum meal powder, wood powder, starch, etc. is 99.7% by mass, uniformly mixed, and then added containing pigment and antiseptic Using a known method, the mosquito repellent incense for controlling tropical infectious disease vectors of the present invention is obtained.

Embodiment 2

[0043] The compound is 0.2% by mass, the heating evapotranspiration accelerator A is 0.5% by mass, and 2,6-di-tert-butyl-4-methylphenol is 0.1% by mass, and coconut shell powder, wood powder, phoebe powder, The base material of the mosquito repellent incense such as starch is 99.2% by mass, uniformly mixed, and then water containing preservatives is added to obtain the mosquito repellent incense for controlling mosquitoes of tropical infectious disease vectors of the present invention by a known method.

Embodiment 3

[0045] [Determination of the effective ingredient volatilization rate in incense smoke]

[0046] On the upper part of the exhaust bell with an internal volume of about 1.5 liters, two traps (inner diameter 25 mm, length 10 cm) for collecting volatile matter filled with about 6 g of silica gel were connected in series to the vacuum pump. Set 2g of the test mosquito repellent incense stick on the incense holder and place it in the center of the bottom surface of the exhaust bell. After ignition, air is drawn at a rate of 8 liters / minute to take samples of the volatile substances. After the smoking is finished, the volatile matter trapped in the trap and the volatile matter 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 effective ingredient volatilization rate was calculated based on the recovered amount relative to the theoretical effective ingredient amount contained in the tes...

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 present invention relates to a mosquito repellent incense for controlling mosquitoes 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 areas 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 causes fatigue. Culex mosquitoes are the vector. In the absence of a proper vaccine today, as a method to prevent these tropical infectious diseases, the most important thing is not to be bitten by mosquitoes, especially in open residences, it is most suitable to use mosquito repellent incense. Pyrethroids are also impregnated in mosquito nets for use, but there are many usability problems, such as use only during be...
