INFLUENCE OF DIFFERENT LARVAL FEEDING REGIMES AND DIET PRESENTATION METHODS ON CHRYSOPERLA-RUFILABRIS (NEUROPTERA, CHRYSOPIDAE) DEVELOPMENT

Results of a comparative analysis of the effects of seven different la rval feeding regimes on the development of individually reared Chrysop erla rufilabris (Burmeister) larvae are presented. Also, four methods for presenting Liquid artificial diet (capillary tubes, sponge, agaros e based jelly, and artificial eggs) are discussed. Development time, p upal weight, fecundity, and reproductive rate were higher for C. rufil abris larvae reared on the eggs of either Helicoverpa tea (Boddie) or Sitotroga cerealella (Olivier) than for those reared on artificial die t. Diet presentation methods that show promise include agarose-based j elly and artificial eggs.
