Embodiment 1

[0029] 1) Repellence test of 1,2-propanediol acetal with 15% hydroxycitronellal on Aedes albopictus.

[0030] Follow the method of national standard GB / T 13917.9-2009.

[0031] Prepare the solution of hydroxycitronellal 1,2-propanediol acetal with absolute ethanol according to the required percentage concentration.

[0032] After confirming the testers and test insects who have passed the attack test, press 1.5μL / cm 2 Apply the medicine, and the other hand is the blank control. Expose the area of ​​4cm×4cm of the coated skin, tightly cover the rest, put your hand into a 40×30×30cm mosquito cage with no less than 300 female mosquitoes at different times, and observe for 2 minutes. Every time as long as one mosquito comes to suck blood, it will be invalid. Record the effective protection time, the results are shown in Table 2.

Abstract

The invention relates to hydroxycitronellal 1,2-propanediol acetal used as repellent. The compound hydroxycitronellal 1,2-propanediol acetal shown as follows can be used as the insect repellent. The hydroxycitronellal 1,2-propanediol acetal of the invention can be used as the substitute of diethyltoluamide to repel Culex pipiens pallens.

Description

technical field [0001] The present invention relates to repellents, especially terpene repellents, specifically hydroxycitronellal 1,2-propanediol acetal against Aedes albopictus, Anopheles sinensis and Culex palustris. pipiens) repellent applications. technical background [0002] Mosquitoes not only harass blood-suckers, but also spread diseases. Diseases such as malaria, filariasis, Japanese encephalitis and dengue fever transmitted by them are extremely harmful to humans. Therefore, mosquito control has always been one of the key tasks of public health. [0003] Mosquito control methods include environmental control, physical control and chemical control, and the public relies heavily on chemical control. Since most of the chemical insecticides are neurotoxic agents, they are harmful to humans, warm-blooded animals and other non-target organisms and the environment, and long-term use will lead to the emergence and development of mosquito resistance. Therefore, the no...
