The study on a biological control of Bemisia tabaci Gen. by Encarsia formosa Gah. on 20 tomato plants under plastic house has been tested with 5 black pupae for one adult Aleurod. The maximal density averages have gone up from 5 pupae the 11 July to 53 pupae the 25 July 1994. The temporal evolution of the rate of the black pupae is growing (20 to 45 per cent) and it is declining (81 to 56 per cent) for the unparasited pupae, respectively the 11 and 25 July 1994
