Experimental study on efficacy of two insecticides against ticks in field
Objective To compare and test the efficacy of lambda-cyhalothrin microcapsule suspension and alpha-cypermethrin suspension concentrate against ticks in the field,and to explore a new method of efficient,stable and long-term effective tick control,so as to rapidly reduce the tick density during the outbreak of tick-borne diseases and emergency situations.Methods The natural field environment with high tick infestation rate was selected,and 3 areas with a scale of 100 m2 were designated,2 were used as test areas and 1 was used as control areas.The tick density in the 3 designated areas was investigated with the flag method before killing.After the background investigation,insecticide was applied to the test area with a common sprayer to carry out tick killing effect test.Results The density of free ticks in the test area was 0 after 1 day of drug spraying,and ticks were detected in the test area sprayed with cypermethrin after 14 days,while no free ticks were detected in the test area sprayed with alpha-cypermethrin after 42 days.The results showed that lambda-cyhalothrin had a longer duration of killing ticks.Conclusion Hygienic insecticides can rapidly reduce the density of free ticks,and lambda-cyhalothrin has better tick killing effect and longer killing duration.
