Seed Treatment with Rubidium for Monitoring Wireworm (Coleoptera: Elateridae) Feeding on Corn

Methods for Marking Insects: Current Techniques and Future Prospects

“…Many other innovative techniques have been developed for marking insect host plants. Corn seedlings have been marked by dipping seeds in a solution containing water or milk, Elmer's glue (Elmer's Products, Inc., Columbus, OH), and RbCl, or by planting seeds on paraffin cubes containing RbCl (36,128). Trees have been labeled by pressure-injecting a solution of RbCl directly into the trunk (26,145,164) or by using a passive-stem-well infusion technique (212).…”

Environmental Influences on Soil Macroarthropod Behavior in Agricultural Systems

“…Conversely, highly mobile soil insecticides will move beyond the root zone and will also be ineffective in controlling soil insects. Contact between the toxic agent and target soil insect is determined primarily through soil factors influencing its passive percolation through the profile (texture, compaction, and organic matter), movement with growing roots, mechanical incorporation into the soil profile through cultivation, and the activity and location of the target insect in relation to the distribution of insecticide residue in the soil profile ( 14,42,60,99,105).…”

“…However, this is not typically the situation with soil insects. As a result, field studies of soil insects often quantify only the consequences of behavior while the behaviors themselves remain hidden within the soil matrix (14,103,105).…”

“…A major obstacle to the study of soil insect ecology has been the inability to follow soil insect movement and feeding behavior in situ (3,14,33,34,103,105). It is critically important in these studies to minimize the disturbance of the soil system through experimental manipulations.…”

Comparison of Topically Applied Rubidium Chloride and Fluorescent Dye Markers on Survival and Recovery of Field-Released Male Spruce Budworm Moths

“…The principal method by which trace elements are introduced into test animals is through ingestion. usually by doping larval or adult artificial diets (Armes et al 1989;Hayes 1989) or natural host plants (Stirnmann 1974Payne and Wood 1984;Culin and Alverson 1986;Cheshire et al 1987;Stadelbacher 199 1). Marking insects using the above techniques can be time-consuming and expensive.…”
