Embodiment 1

[0028] The acaricidal activity of the compound shown in embodiment 1, formula II

[0029] The preparation method of the negative control solution is as follows: add dimethyl sulfoxide (DMSO) to distilled water, so that the final concentration of DMSO is 5% (volume percentage), to obtain the negative control liquid.

[0030] The preparation method of the compound medicine solution shown in formula II is as follows: add the compound of formula II to the negative control medicine solution to obtain the compounds with the concentration of the compound of formula II being 0.5mg / mL, 1.0mg / mL, 1.5mg / mL, and 2.0mg / mL respectively. A liquid medicine of the compound represented by the formula II.

[0031] The acaricidal activity of the compound shown in the formula II and the negative control solution was determined by slide dipping method, the experiment was repeated three times, and the operation steps were as follows:

[0032] Take a clean glass slide, paste the double-sided tape on...

Abstract

The invention provides application of an amine compound to prevention and control of pest mites. The structure of the amine compound is shown as a formula I. The pest mites include agricultural pest mites, and / or forestry pest mites, and / or garden pest mites and / or cabin pest mites. As proved by experiments, the compound shown as the formula I (particularly is N-methyl-1-(4-methylpyridine-2-yl)-N-(2-phenethyl)-2-propylamine shown as a formula II) has a very good toxic killing effect on mites, and the toxic killing effect can be improved along with the rise of the concentration of the compoundshown as the formula I in liquid medicine for treating tetranychus cinnabarinus, and is far higher than the corrected death rate of female adult tetranychus cinnabarinus treated with a negative control (the negative control is nontoxic to the mites basically). (The formulas I and II are shown in the description).

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to the application of amine compounds in preventing and controlling harmful mites. Background technique [0002] Tetranychus cinnabarinus belongs to Arachnida and Acarina, and it is an important economic pest in the world that endangers agriculture and forestry, and it is recognized as a harmful biological community that is difficult to control. It has the characteristics of extensive damage to the host, easy to produce drug resistance, and serious harm. Tetranychus cinnabarinus can reproduce sexually and parthenogenetically. The female adults of Tetranychus cinnabarinus have the habit of overwintering. They are difficult to be found and eliminated in winter, and they often reproduce in large numbers in the second spring, which makes the control of Tetranychus cinnabarinus difficult. [0003] According to the statistics of the General Administration of Customs of the People's Republic...
