    Notes: Abstract Ceralure or trimedlure polymeric TNO panels in C&C traps were compared for attractancy by the capture of male Mediterranean fruit flies, Ceratitis capitata (Wiedemann). This study contrasts the effectiveness of ceralure with trimedlure, the former of which is an iodo-analog of trimedlure. Field tests in Hawaii with released flies showed that the active ceralure B1 isomer in a commercial mixture of ceralure isomers consistently caught as many male flies as active trimedlure C isomer in a commercial mixture of trimedlure isomers at one-half the molar quantity of trimedlure C. These panels caught 6.4 and 5.2 times, for ceralure and trimedlure, respectively, more than the standard 2 g trimedlure AgriSense aged plug over a 26-week period. The persistence of ceralure is demonstrated by residual analyses of aged panels that revealed the presence of 2.75 times more ceralure than trimedlure in panels after 130 days of field exposure.

    Notes: Abstract The Mediterranean fruit fly, Ceratitis capitata, is a major pest of fruits and vegetables in the world. With the help of an extensive trapping program, the continental United States has remained free of established medfly populations. In an effort to increase trapping efficiency, controlled-release polymeric panels with trimedlure and ceralure were developed in conjunction with the development of a new trap, the C&C trap. This study contrasts the effectiveness of different panel formulations with the standard trimedlure polymeric plug and describes the use of the panels in the C&C trap. Field tests in Hawaii using released sterile flies showed consistently higher male medfly catches with panels in C&C traps than with the standard trimedlure polymeric plug in Jackson traps.

    Finite-size effects in random energy models and in the problem of polymers in a random medium (1991)
    Springer
    Journal of statistical physics 63 (1991), S. 505-539 
    Details
    ISSN: 1572-9613
    Keywords: Spin-glass ; finite-size effects ; directed polymers ; traveling waves
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract By the use of traveling wave equations we calculate the finite-size corrections to the free energy of random energy models in their low-temperature phases and in the neighborhood of the transition temperature. We find that although the extensive part of the free energy does not show any critical behavior when the temperature approaches its transition value, the finite-size corrections signal the transition by becoming singular. We obtain a scaling form for these finite-size corrections valid in the limitN→∞ andT→T c . By considering a generalized random energy model in the limit of a very large number of steps, we obtain results for the finite-size corrections in the problem of a polymer in a random medium.
