Traps consist of a double-sided yellow cardboard with an un-baited sticky coating and are suspended from a pole 1.2 m above the ground. These traps have the advantages of being simple to maintain, low cost, suitable for a variety of habitats, and easy to remove for agronomic practices; this allows for sampling of many locations over a large area. 
Sticky traps are monitored weekly during the growing season. Adults of species of interest that collect on the sticky traps are identified in the field using a pictorial key, counted, recorded on sampling sheets, and then removed from the card. Traps are replaced every two weeks. Species new to sticky trap collections are preserved in ethanol for later identification and are included in future predator counts (e.g. new species records, invasive species). Data and ancillary information are entered in a statistical spreadsheet for analysis and archiving.
For the Main Cropping System Experiment (MCSE), abundances are monitored weekly throughout the growing season (early May to late August) at each of the five permanent sampling stations per replicate in all treatments except in the Mown Grassland Never-tilled treatment (T8). Permanent sampling sites allow monitoring of temporal variation (weeks, years) while accounting for spatial variation. For the MCSE treatment plots, a total of 255 sampling stations are monitored [(since 1989, 7 treatments at the LTER Main Site x 6 replicates x 5 stations) + (since 1993, 3 successional and forest site x 3 replicates x 5 stations)]. Since 2019, monitoring also occurs at 3 sampling stations per prairie strip in T3 and T4. </description><protocol id="protocol_192"><title>Insect Abundance - Sticky Traps</title><creator><positionName>Data Manager</positionName></creator><distribution><online><url>http://lter.kbs.msu.edu/protocols/192</url></online></distribution></protocol></methodStep></methods><project><title>LTER: KBS - Ecological and Social Mechanisms of Resilience in Agroecosystems</title><personnel><organizationName/><role>program</role></personnel><award><funderName>National Science Foundation</funderName><funderIdentifier>http://dx.doi.org/10.13039/100000001</funderIdentifier><awardNumber>DEB 2224712</awardNumber><title>LTER: KBS - Ecological and Social Mechanisms of Resilience in Agroecosystems</title><awardUrl>https%3A%2F%2Fnsf.gov%2Fawardsearch%2FshowAward%3FAWD_ID%3D2224712%26HistoricalAwards%3Dfalse</awardUrl></award></project><dataTable><alternateIdentifier system="lter.kbs.msu.edu">https://lter.kbs.msu.edu/datatables/67</alternateIdentifier><entityName>Kellogg Biological Station LTER: Insect Populations via Sticky Traps (KBS023-001)</entityName><entityDescription>Identification and abundance of plant dwelling predator insect species adhering to sticky traps after one week of deployment throughout the growing season.
