目的调查某战备仓库蜱虫侵害情况及影响因素,评价控制蜱虫危害的效果。方法采用目测法、药激法、人工小时布旗法调查蜱虫危害,观察蜱虫防制效果。结果犬带蜱指数平均达2520,蜱虫密度最低8只/400 cm2,最高>200只/400 cm2,孳生侵害范围与饲养犬活动范围一致;室内用0.2%奋斗呐水乳剂与0.3%残杀威.右旋苯醚氰菊酯复配液滞留喷洒,室外环境用0.1%高效氯氟氰菊酯与2%倍硫磷复配液常规喷洒,第1次处理后蜱虫密度降至3只/400 cm2以下,第2次处理后蜱虫密度降为0。结论经2次环境滞留喷洒处理,结合对饲养犬灭蜱控制等措施,可有效控制仓库蜱虫危害。
Objective To investigate the situation and influential factors of ticks in a battle preparedness warehouse and evaluate the effect of controlling the damage of ticks. Methods The visual inspection method, the drug-induced method, the artificial hour cloth method were used to investigate the damage of ticks and the control effect of ticks was observed. Results The average index of canis ticks was 2520, the lowest tick density was 8/400 cm2 and the highest was> 200/400 cm2. The range of infestation was the same as that of rearing dogs. Indoor use of 0.2% Dex Phenothrin cypermethrin solution was sprayed and sprayed, the outdoor environment was sprayed with 0.1% lambda-cyhalothrin and 2% fenthion complex solution, and the density of the ticks after the first treatment was reduced to 3 / 400 cm2 or less, after the second treatment, the density of ticks dropped to zero. Conclusion After two times of environmental sprinkling treatment, combined with the control of ticks and other measures of feeding dogs can effectively control the warehouse ticks harm.
