Abstract:The lesser bulb fly was reared from infested bulbs received from California and Washington. The pupal period varied from 8 to 16 days. Maximum longevity of flies was 23 days. Flies were fed on honey. Mating occurs in sunlight. Small white eggs were deposited in masses between layers of dry brown skin at neck of bulb, but not in decaying bulbs. Larvae in feeding ra~p the bulb tissue with their mouth hooks. Later they feed in decaying or fermenting areas. Some larvae which hatched Auguse 26, pupated a month later and emerge:! during October. While the other larvae of the same generation have not pupated after more than three months. Larvae reared from the partial brood that emerged are now practically the same size as those of the previous generation.
The evidence is not yet conclusive, but it is probable that this species deserves recognition as a potential enemy of narcissus bulbs and onions.
