CHART: Japanese beetle population trends

February 7, 2013 | 6:29 p.m. CST
The population of Japanese beetles in Columbia has declined from the record high in 2010. Despite the drop in population, the numbers might rise again due to several different factors, including an increase in rainfall since last year. This chart displays the approximate number of adult beetles found in the trap each year at the A.L. Gustin Golf Course over the course of the season. Trapping begins the last week of May and continues through the end of August each year.
