Information is provided on the biology, injuriousness, parasitoids and chemical control of Bembecia scopigera on sainfoin (Onobrychis viciifolia) in the laboratory and field in Turkey in 1984-87. Adults appeared from early July to early October, and sex pheromone traps were useful for monitoring the flight period. Newly-hatched larvae occurred in mid-July and at the end of July, and the larvae fed in the pith within the roots. Overwintering began at 8.3-11.3 degrees C, and feeding began at 12.3-18.3 degrees C. Larval overwintering was not obligatory at 25 degrees C. There were up to 17 larvae in a root, at depths of up to 12 cm. The pupal period was 15-20 days, depending on temperature, and the sex ratio 1:1.
