Marking cabbage looper (Lepidoptera: Noctuidae) with cesium
Environmental Entomology 13 (2), 390-393
Abstract: Cabbage loopers (CL), Trichoplusia ni (Hübner), adults reared on artificial diet containing 1 x 10^-2 M and 1 x 10^-3 M CsCI were marked with cesium (Cs) which could be detected by atomic absorption spectropbotometry. The cesium marks from the 10^-2 M CsCl diet were sufficient to last the expected lifetime of the insects. CL reared on diet containing 1 x 10^-1 M CsCI did not survive. Unmarked females mated to males reared on artificial diet containing 1 x 10^-2 M and 1 x 10^-3 M CsCl were marked. CL reared on cotton plants sprayed with Cs solutions of 1,000, 5,000, and 10,000 µg/ml were marked sufficiently to last the expected lifetime of the insect. CL adults exposed for 72 h to cotton plants sprayed with Cs solutions of 1,000, 5,000, and 10,000 µg/ml were marked sufficiently to last the expected lifetime of the insect. CL adults reared from field cotton plants sprayed with CsCl solutions at rates of 1.24, 2.47, and 4-94 kg of CsCl per ha were marked.
