作者对山东费县小盾纤恙螨幼虫生态习性进行了实验室观察和现场防治研究,结果表明:小盾纤恙螨季节消长呈明显秋冬型,集中出现于9月～12月,以11月中旬为高峰。10月份采用小白鼠法在草地诱获小盾纤恙螨阳性率为16％～20％;小黑板法诱集共130只小盾纤恙螨未食幼虫。采用敌敌畏和以二氯苯醚菊酯为主的神龙牌杀虫剂进行杀灭实验,结果显示小盾纤恙螨对该两种杀虫剂敏感,且灭效至少可维持一个月以上。
The authors conducted a laboratory observation and site control study on the ecological habits of Chigger mite larvae in Feixian County, Shandong Province. The results showed that the seasonal fluctuation of Chigger mites was obvious in autumn and winter, mainly occurring in September-December, Mid-peak. In October, the positive rate of small shield chigger mites was 16% ~ 20%. The small blackboard method seized a total of 130 small shield chigger mites. Dichlorvos and Permethrin-based Shenlong brand pesticides were used in the killing experiments. The results showed that these two insecticides were susceptible and could be maintained for at least one month.
