An annotated list of 83 scale insect species (Hemiptera: Sterorrhyncha: Coccoidea) recorded from Saint Lucia is presented, based on data gathered from UK quarantine interceptions, samples collected in an urban coastal habitat in the North West of the Island in 2013, and published records. Thirty-three species (40%) are recorded for the first time for the country, including Dysmicoccus joannesiae (Costa Lima), a South American mealybug, and Poliaspoides formosana (Takahashi), an Asian armoured scale insect pest of bamboo, which are new for the Caribbean region. The economic, environmental and social impacts caused by introduced exotic species of scale insect are discussed. Two predatory midges Diadiplosis ?coccidivora (Felt) and Diadiplosis multifila (Felt) (Diptera: Cecidomyiidae) are recorded for the first time from Saint Lucia. The latter species was observed causing 90% mortality of a large infestation of passion vine mealybug Planococcus minor (Maskell) on soursop fruit.
本文基于从英国检疫拦截数据、2013年在该岛西北部城市沿海栖息地采集的样本以及已发表记录，列出了一份来自圣卢西亚的83种介壳虫（半翅目：粉虱亚目：蚧总科）的注释清单。该国首次记录了33种（40%）介壳虫，包括南美粉蚧Dysmicoccus joannesiae（科斯塔·利马）和竹类亚洲 armored scale insect pest Poliaspoides formosana（高桥），它们是加勒比地区的新物种。文中讨论了外来入侵介壳虫物种所造成的经济、环境和社会影响。首次从圣卢西亚记录到两种捕食性蠓虫，即Diadiplosis?coccidivora（费尔特）和Diadiplosis multifila（费尔特）（双翅目：瘿蚊科）。观察到后一种蠓虫致使刺果番荔枝果实上的番荔枝粉蚧Planococcus minor（马斯克尔）大量侵染死亡率达到90%。
