Harmonia axyridis is a ladybird extensively used around the world for biological control of agricultural pests. However, it has become invasive in several countries, producing negative ecological and socio-economic impacts. Herein, we review the invasion history of the Harlequin Ladybird Harmonia axyridis (Pallas, 1773) in Ecuador. Although first reported in Ecuador in 2012, museum specimens date back to 2004 and it is currently established across the country, especially along the Andean region. Due to its invasive nature, further studies are urgently needed to evaluate possible impacts of H. axyridis on the Ecuadorian biodiversity and agroindustry.

Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) 在厄瓜多尔的入侵历史

Harmonia axyridis 是一种在世界各地广泛用于农业害虫生物防治的瓢虫。然而，它已经在一些国家成为侵入性的，产生了负面的生态和社会经济影响。在此，我们回顾了丑角瓢虫 Harmonia axyridis (Pallas, 1773) 在厄瓜多尔的入侵历史。尽管于 2012 年首次在厄瓜多尔报道，但博物馆标本可追溯到 2004 年，目前已在全国各地建立，尤其是安第斯地区沿线。由于其侵入性，迫切需要进一步研究以评估 H. axyridis 对厄瓜多尔生物多样性和农业产业的可能影响。
