Changes in population dynamics of Cerambycidae in relation to climate change and other environmental stressors

Longhorn beetles contribute to a healthy forest by returning nutrients from dead and unhealthy trees to the soil. The lumber industry is one of the top three industries in South Carolina for jobs, income, and economic output in the state, and it depends on proper forest management to maintain this renewable resource. The South Carolina Longhorn Survey is a three-year study of longhorn beetles at sites throughout South Carolina with emphasis on the four major ecoregions within the state. The two main goals of the survey are to: 1) measure the diversity and relative abundance of longhorn beetles using an established trap sampling protocol, and 2) develop an updated checklist of longhorn beetle species for South Carolina. A trap sampling protocol was developed and tested that uses panel traps, generic chemical lures, sugar traps and light traps. The survey is currently in its second year at four major sites and several alternative sites throughout South Carolina. After establishing a baseline measurement, follow up surveys can be conducted to monitor changes, such as species migration due to climate change and insect population declines. A review of the trapping strategy as well as an update on the current progress of the project will be provided.
