Modulation of inward potassium ion conductance with structurally diverse small-molecules in the arthropod salivary gland induces arthropod salivary gland failure that results in a reduction or elimination in the ability of the arthropod to feed. Administering Kir channel inhibitors reduces food intake, increases feeding time, reduces salivary gland secretion, induces mortality, and reduces transmission of vector-borne pathogens. Kir channel inhibitors induce these adverse effects in ticks, mosquitoes, horn flies, and aphids.

The invention relates to a liquid-phase synthesis multi-ion doped K2MgSi5O12 potassium fast ion conductor and a preparation method thereof. The liquid-phase synthesis multi-ion doped K2MgSi5O12 potassium fast ion conductor is characterized in that the stoichiometric formula is K2.24MgCa0.05Ba0.02Be0.2P0.02Ti0.02Si4.76O12; and the conductivity of potassium ions at room temperature is higher than 5*10<-4>S / cm. Be2+ partially replace Si4+ ions to produce interstitial potassium ions in a crystal, so as to reduce the activation energy of potassium ion migration. The size of the potassium ion migration channels is adjusted through doping of Be2+ with small ion radius in order to adapt to the rapid migration of potassium ions. A distorted lattice structure is formed through partial doping of Ti4+in order to increase lattice defects and facilitate potassium ion conduction. The electronic conductivity of the fast ionic conductor is further reduced through doping of P5+. Through partial dopingof Ca2+ and Ba2+, cation vacancies are formed to increase potassium ion migration paths. The surface of K2MgSi5O12 particles is modified in the preparation process to make the conductor easy to sinter. The synergistic effect makes the conductivity of potassium ions of the potassium fast ionic conductor exceed 5*10<-4>S / cm at room temperature, which is closer to the conductivity of potassium ions of liquid electrolyte.
