Abstract:         Mating behavior and capacity in the Piophila casei L.were investigated under laboratory conditions (27 ℃ ±1℃, L∶D =12∶12). The results indicated that the females were able to mate immediately after emergence, and the males started to mate 30 min after emergence. Peaking matingrate occurred in the both sexes that just emerged 80 min. It was observed that daily matingpeak occurred from 10∶00 to 11.00. Mating duration of both sexes was mainly about 5 min with a range from 4 to 9 min. Behavioral observation indicated that females mated only once, and males could mate more than 2 times (1-7 times) with a peak of 2 times (45%).
