SUMMARY Wheat bulb flies were bred successfully at all times of the year. Larvae were obtained out of season by delaying hatching; the emerging larvae successfully infested wheat seedlings kept at 15°C or below. When larval development was complete, infested plants were moved to cages in a glasshouse for pupation and adult emergence. After emergence and during the pre‐oviposition period (one month) the flies were provided with a diet of aphid honeydew, honey solution, dried milk and yeast mixture, and mammalian blood. After mating, the females were moved to lantern‐glass breeding chambers kept at about 20°C, where they laid eggs. The eggs were stored for 8 wk at 20°C followed by at least 14–16 wk at 0°C before being used to infest winter wheat seedlings. More flies were produced when plants were kept at temperatures fluctuating between 5 and 15°C than at constant temperatures of 10 and 15°C.
