In vitro rearing of the pupal parasitoid Brachymeria intermedia (Hym.: Chalcididae) on artificial diets with and without host components

摘要: The pupal parasitoidBrachymeria intermedia (Nees) was reared from the egg to adult stage on artificial media based commercial meat homogenates for babies (Plasmon®), either with or devoid of host components. Six containing 80% homogenate and 20% extract ofGalleria mellonella L. pupae were tested first. Two types homogenates, intended at beginning weaning (a) well in (b), utilized. Media beef, veal chicken meat, 3 a-homogenates b-homogenates. A significantly higher percentage parasitoids developed as mature larvae a- than b-homogenate diets. This presumably related protein, carbohydrate, lipid calorie level b- homogenates. Diet veal-a produced best mean yield (27.4%). Other two diets then tested. first, composed homogenate, 10% extract, 7% yolk, 1.5% yeast wheat germ, a 66.7%, similar that obtained inG. pupae. On second medium, components 85% 2.5% germ 22.5%. In all media, adults viable fecund.
