To control B.argentifolii on tomatoes in plastic greenhouses, Encarsia formosa (EN-STRIP^[○!R] produced by KOPPERT BV) was released once or three times at about twice the adult density of the whitefly. In control plots, the population density of the whitefly increased progressively to a high level causing sooty mold and irregular ripening of tomato fruits. In the releasc plots, the population density of the whitefly was held at a lower level and no damage was caused. Non-parasitization mortality of B.argentifolii was relatively high and seemed to be caused by host feeding and undetermined mortality factors. E.formosa can survive and reproduce in plastic greenhouses whiere daily maximutn temperatures exceeded 35℃ for 7-11 days.
