AbstractGamma-emitting radionuclides, which have individually identifiable energy spectra, were used singly and in combination to label workers of the subterranean termite Retimlitmes fhvipes Kol. Isotopes offered in the food source were incorporated into workers and showed discernible spectra within three days, and all workers showed statistically identifiable label within 10 days.Labeled termites spread the nuclide to other colony members via trophallactic exchan es.(125.9 days). Social interactions appear to lengtien the biological half-lives of isotopes and increase the persistence of a label. All colonies showed a steady increase in the elimination of radioactivity with elimination rates ranging from 2.6 YO for 54Mn to 17 % for boCo. The low elimination rate for %Mn correlates with its long biological life.U.S.

Temperature Effect on Kinetics of Uptake, Transfer, and Clearance of [<SUP>14</SUP>C]Noviflumuron in Eastern Subterranean Termites (Isoptera: Rhinotermitidae)

“…The use of radiolabeled compounds to characterize feeding, trophallaxis, and foraging in drywood termites has been reported by Afzal (1983aAfzal ( , b, 1984 who found that trophallactic rates were affected by group size, feeding potentials, and excretory differences among groups of termite colony members. Other researchers investigated trophallaxis and feeding behavior in termites by using radioactive compounds (Mc-Mahan 1963, Khan et al 1981, Traniello et al 1985, Rosengaus et al 1986). Spragg and Fox (1974) and Spragg and Patton (1980) used a radioactive tracer to determine nesting systems and estimate population levels.…”

Workers do not mediate the inhibitory power of queens in a termite, Reticulitermes speratus (Isoptera, Rhinotermitidae)

“…Then, 20 workers were chosen randomly from each group and exchanged between the direct and indirect contact group pair every 48 h. Trophallaxis is a probable mechanism for caste regulatory pheromone transfer in termites (Lüscher, 1960). Compared with the social Hymenoptera (Markin, 1970;Traniello, 1977), the termite trophallaxis rate is generally slow (Afzal, 1983;Traniello et al, 1985;Rosengaus et al, 1986;Suárez and Thorne, 2000). In a study of the trophallaxis rate in Reticulitermes flavipes using a radioactive tracer, 48-72 h was required for most of the members to acquire the isotope when five potential donors were placed with 45 worker nestmates (Suárez and Thorne, 2000).…”
