Abstract : Several experiments carried out in the field in Mexico in 1983-85, in which using Jackson traps baited with various wick loadings of trimedlure (TML) were placed in coffee or mango trees, failed to show evidence of repellency by Ceratitis capitata at high concentrations, although an asymptotic-type response curve was evident. TML-impregnated cotton dental rolls demonstrated fairly linear evaporation rates. The results suggested that rubber septa show promise as an alternative type of dispenser to cotton wicks. Capilure, a more slowly evaporating formulation of TML, proved to be less attractive than TML. The trapping strategies and future lines of research are discussed with reference to the sterile release programme being conducted in Chiapas, Mexico.
