Abstract

The invention relates to a tick-killing biological control agent. Suspension emulsion or powder can be prepared from 90 to 99 mass percent of spore powder of beauveria bassiana and 1 to 10 mass percent of celangulin which serve as main raw materials. The spore powder of beauveria bassiana is obtained by performing vacuum drying and pulverization on conidia which is obtained by performing liquid-solid two-phase fermentation on the beauveria bassiana, and vibrating the pulverized conidia by using a 120 to 200-mesh sieve, wherein the spore content is counted by using a blood counting chamber. The tick-killing biological control agent can be prepared into various required formulations such as the powder or the suspension emulsion and the like. The tick-killing biological control agent has the advantages of strong pathogenicity to ticks, safety for humans, domestic animals and other living beings, no environmental pollution, difficult generation of medicament resistance, better comprehensive prevention and control effect, high compatibility between the beauveria bassiana and the celangulin in the compounded biological tick-killing agent, better effect of killing the ticks compared with singly used beauveria bassiana or celangulin, lower cost, simpler production process and easy operation.

Description

technical field [0001] The invention relates to the technology of insecticide preparations, in particular to a new tick-killing biological control preparation for preventing and controlling ticks and a preparation method thereof. Background technique [0002] Ticks belong to the order Acarinae and the Superfamily Acaridae. They are a common type of ectoparasites on the surface of animals. They are widely distributed all over the world and can attack humans, mammals, birds, reptiles and amphibians through bites. The harm of ticks is directly manifested as the decline in production performance caused by the turmoil and wound infection of the bitten animals. When a large number of parasites are parasitized, the toxin secreted by ticks causes paralysis of animals, resulting in tick paralysis. In addition, ticks are the vectors of diseases such as Lyme disease, spotted fever, Q fever, forest encephalitis, hemorrhagic fever, babesiosis, theileriasis and aplasmosis, and they are in...
