Abstract A series of studies was conducted to test methods for marking a wide variety of arthropods with inexpensive proteins for mark‐capture dispersal research. The markers tested included egg albumin protein in chicken egg whites and casein protein in bovine milk. The first study qualified the effectiveness of the two marks on more than 50 arthropod species inhabiting cotton via two application procedures. The application methods included: (1) a topical plus residue protein application, and (2) a residue‐only protein application. Both protein marks, regardless of the method of application, were readily retained on the arthropod assemblage over the duration of the study. The second study determined how rapidly insects acquire chicken egg albumin protein after contact exposure to cotton tissue sprayed with an egg whites solution. Under laboratory conditions, the vast majority of adult Hippodamia convergens Guérin‐Méneville (Coleoptera: Coccinellidae) and Lygus hesperus Knight (Heteroptera: Miridae) acquired the mark after 5 min, and immature Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) acquired the marker after 40 min. The third study determined how rapidly H. convergens and L. hesperus acquire bovine casein protein after contact exposure to either alfalfa, Medicago sativa L. (Fabaceae), or lesquerella, Lesquerella fendleri (Watson) (Brassicaceae), plants sprayed with a bovine milk solution. These insects rapidly acquired the casein mark from the plant residue under field conditions. A final study determined how long H. convergens retain casein protein after 24‐h exposure to alfalfa and lesquerella plants containing a 7‐day‐old residue of bovine milk. Approximately 95% of the H. convergens maintained the casein mark for 2 days after removal from each type of plant.
