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 matingrate occurred in the both sexes that just emerged 80 min. It was observed that daily matingpeak 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%).
