Chaetocnema minuta Melsh., a Nearctic flea beetle, has been recently isolated from damaged perennial ryegrass (Lolium perenne L. var. Palmer/Prelude) and hybrid bermudagrass (Cynodon dactylon L. Pers. × Cynodon transvaalensis Burtt Davy var. Midiron) in southern Utah and Nevada, respectively. Though previous surveys have found this insect associated with grasses, this short communication is the first report of economic damage to turfgrasses. Little is known about C. minuta seasonal phenology and host plant damage, and the distribution and understanding of the population dynamics in the Southwestern United States remain unstudied. Area turfgrass managers report the need for multiple insecticide applications throughout the growing season to maintain populations below turf damaging levels. This report serves to characterize turfgrass damage and document monitoring efforts to assist with future management programs.

首次报告与美国西南部沙漠草坪损害有关的细毛壳线虫（鞘翅目：Chrysomelidae）

最近从受损的多年生黑麦草 (Lolium perenne L. var. Palmer/Prelude) 和杂交狗牙根 (Cynodon dactylon L. Pers. × Cynodon transvaalensis Burtt Davy var. Midiron) 中分离出了近北区跳蚤甲虫 Chaetocnema minuta Melsh.分别是犹他州和内华达州。虽然之前的调查发现这种昆虫与草有关，但这种简短的交流是关于草坪草经济损失的第一份报告。对 C. minuta 季节性物候和寄主植物损害知之甚少，对美国西南部种群动态的分布和理解仍未研究。区域草坪管理人员报告说，需要在整个生长季节使用多种杀虫剂，以将种群保持在草坪破坏水平以下。
