none Apanteles creatonoti Viereck, a larval parasitoid of Thiocidas postica Wlk., a pest on ber tree was studied under laboratory conditions (24 plus or minus 1 degree C, 55-60% R H). The eggs are white and hymenopteriform. Eclosion occurs 3 days after oviposition. There are 3 instars. The first two are vesiculate and last hymenopteriform. Matured parasitoid larvae emerged from the host, killing it and then spun a silver-white cylindrical cocoon. The total developmental time from egg to adult was 14-15 days. Egg stage 3 days, larval stage 6-7 days and pupal stage 5 days.
