By the method of pitfall trapping, an investigation was conducted on the diversity of ground-dwelling ants in a lac plantation in Yayi Town of Mojiang County, Yunnan Province of Southwest China in December 2009-May 2010, aimed to understand the effects of lac insect honeydew on the diversity of ground-dwelling ants. The presence or absence of lac insect honeydew and its dynamics all affected the species composition, abundance, and diversity of ground-dwelling ants. In the lac plantation with lac insect hosting, a total of 4953 ant individuals were collected, belonging to 34 species, 23 genera, and 5 subfamilies of Formicidae; whereas in the lac plantation without lac insect hosting, a total of 2416 ant individuals were collected, belonging to 30 species, 20 genera, and 5 subfamilies of Formicidae. The relative abundance, species richness (S), and ACE index in the lac plantation with lac insect hosting were higher than those in the lac plantation without lac insect hosting, and the common species and indicator species of ground-dwelling ants in the lac plantation with lac insect hosting differed from those in the lac plantation without lac insect hosting, suggesting that lac insect hosting altered the community structure of ground-dwelling ants. The adult lac insects excreted larger quantity of honeydew than the larval lac insects, and the relative abundance, S, and ACE index of ground-dwelling ants were higher at the adult stage than at the larval stage of lac insects. The common species and indicator species of ground-dwelling ants also had great differences between the two stages of lac insects.
2009年12月至2010年5月，采用陷阱诱捕法对中国西南部云南省墨江县雅邑镇紫胶种植园内地面活动蚂蚁的多样性进行了调查，旨在了解紫胶虫蜜露对地面活动蚂蚁多样性的影响。紫胶虫蜜露的有无及其动态变化均影响了地面活动蚂蚁的物种组成、数量和多样性。在有紫胶虫寄生的紫胶种植园中，共采集到4953只蚂蚁个体，隶属于蚁科的5个亚科、23个属、34个种；而在无紫胶虫寄生的紫胶种植园中，共采集到2416只蚂蚁个体，隶属于蚁科的5个亚科、20个属、30个种。有紫胶虫寄生的紫胶种植园中蚂蚁的相对多度、物种丰富度（S）和ACE指数均高于无紫胶虫寄生的紫胶种植园，且有紫胶虫寄生的紫胶种植园中地面活动蚂蚁的常见种和指示种与无紫胶虫寄生的紫胶种植园不同，这表明紫胶虫寄生改变了地面活动蚂蚁的群落结构。紫胶虫成虫分泌的蜜露量大于幼虫，且紫胶虫成虫阶段地面活动蚂蚁的相对多度、S和ACE指数均高于幼虫阶段。地面活动蚂蚁的常见种和指示种在紫胶虫的两个阶段也存在很大差异。
