- Abstract
Bradysia odoriphaga Yang and Zhang (Diptera: Sciaridae) was discovered in the Welsh onion fields of northern Saitama in 2014 and the carrot fields of northern Saitama in 2015, and later in Chinese chive fields in central Gunma Prefecture. Elucidation of the dispersal ability of B. odoriphaga is important for its control. We investigated the flight and walking activities of B. odoriphaga and B. impatiens (Johannsen). The flight and walking durations of adults at 16, 19, 24, and 30°C were investigated by video recording. The flight duration of B. odoriphaga was significantly shorter than that of B. impatiens. In females of B. odoriphaga, the longest continuous flight duration was 2.4 seconds. The walking durations of male B. odoriphaga adults and both sexes of B. impatiens adults were not affected by temperature. In females of B. odoriphaga, the walking durations at 19 and 16°C were significantly shorter than those at other temperatures. Our results suggest that the range of B. odoriphaga dispersal is narrow.
