ABSTRACT
The Columbia Basin of Oregon and Washington is one of the most productive potatoes, Solanum tuberosum L., growing regions in the United States affected by numerous insect pests. Lygus bugs, Lygus spp. (Hemiptera Miridae), are an increasing problem in potatoes. In 2015, after an outbreak of lygus bugs in potatoes in the Columbia Basin, potato producers used multiple applications of insecticides to control lygus bugs. However, it is poorly researched whether lygus bugs can cause economic damage to the crop. Therefore, our objectives were (i) to determine lygus bugs presence in potato plants, (ii) to determine damage on most commonly grown potato varieties (e.g., Alturas Russet, Ranger Russet, Umatilla Russet, Russet Burbank, and Clearwater Russet), (iii) to determine the number of insecticide applications needed to control lygus bugs, and (iv) to estimate the relationship between lygus bug density and potato yield loss. This study demonstrated that the lygus complex is widely present in the Columbia Basin, Lygus spp. prefers the upper 1/3 section of potato plants in all varieties tested, and the number of applications throughout a field season does not affect yield regardless of variety.
