In 2009, a new pest of cassava crops was observed in the Federal District (Brazil) and identified as Eubulus (Kirsch) sp. (Coleoptera: Curculionidae). The pest is currently distributed in the states of Goiás, Minas Gerais, Mato Grosso do Sul, and Paraná. The larvae consume roots, causing the tissue to rot and making it unfit for consumption. The damage can extend to 100% of the roots. Owing to the potential losses that this pest is capable of causing, studies are needed on its biology, ecology, and future management strategies aimed at minimizing the losses, allowing the continuity of cassava cultivation in Brazil. This study reports on the occurrence of the pest in Brazilian Cerrado, its distribution in Brazil, the symptoms of its infestation and estimates the damage caused.
2009 年，在巴西联邦区（巴西）观察到一种新的木薯作物害虫，并鉴定为 Eubulus（Kirsch）sp.（鞘翅目：象甲科）。该害虫目前分布在戈亚斯州、米纳斯吉拉斯州、南马托格罗索州和巴拉那州。幼虫会吃掉根部，导致组织腐烂，无法食用。损害可能会延伸到 100%的根部。由于这种害虫可能造成的潜在损失，需要对其生物学、生态学以及旨在将损失降至最低、允许巴西继续种植木薯的未来管理策略进行研究。本研究报告了该害虫在巴西塞拉多地区的发生情况、在巴西的分布情况、感染症状以及对损失的估计。
