    Description / Table of Contents: Résumé Les dégâts accrus à la canne à sucre, dus àElasmopalpus lignosellus, en liaison avec la destruction des feuilles par le feu avant la récolte, ont incité à faire des investigations sur les ennemis naturels de ce ravageur à Trinidad. Trois parasites ont été élevés:Plagiprospherysa trimtatis Thompson,Mocrocentrus sp. etAgathis rubricinctus Ashmead. Les auteurs décrivent leurs techniques de laboratoire pour la multiplication deP. trinitatis et de son hôte; ils passent en laboratoire pour la multiplication deP. trinitatis et de son hôte; ils passent en revue les essais qui ont été faits pour utiliser des espèces voisines pour la lutte biologique, et discutent brièvement les possibilités d'utilisation deP. trinitatis.
    Notes: Abstract Increased damage to sugarcane byElasmopalpus lignosellus associated with preharvest burning in Barbados, has prompted an investigation of its natural enemies in Trinidad. Three parasitesPlagiprospherysa trinitatis Thompson,Macrocentrus sp. andAgathis rubricinctus Ashmead were reared. Laboratory techniques for breedingP. trinitatis as well as its host are described. Attempts to utilize related species for biological control are reviewed and the possibilities of utilizingp. trinitatis are discussed briefly.

    Notes: The impedance characteristics of parchment-supported inorganic precipitate model membranes have been analyzed in order to understand the mechanism of ionic diffusion through biomembranes. The observed values of membrane capacitance and resistance were found to be dependent on the concentration of bathing electrolyte and applied oscillator frequency. The change in membrane capacitance and resistance values with the change in electrolyte concentration and oscillator frequency has been interpreted in terms of changes produced in the electrical double layer at the membrane-solution interface. The values of interfacial double layer capacitance derived by the equations of Armstrong and Longer were found to be different due to the presence of polarising charge and other structural details of membrane matrix. Different model-equivalent electrical circuits have been analyzed using the experimental data. The complex impedance spectra have been found to deviate from the theoretical predictions at low frequencies due to nonhomogenous and rough surface of the membrane.
