Study on the Flight Performance of Adult Alligator Flea Beetle,Agasicles hygraphila

The flight performance(speed and duration)of adult alligator flea beetle(Agasicles hyraphila)was studied by applying the flight mill.Our results showed that there is only a short period(<3min)flight for a large proportion of female and male individuals tested.In contrast,a small proportion of adults(3%of females and 1%of males)had capacity for long-distance flight(>3min).Meanwhile,the flight duration of female adults was longer than that of males and the longest was recorded at 1.51hby a male adults.Furthermore,the average speed of female and male was 23.07cm·s-1 and 27.72cm·s-1 respectively.Our results indicate that the flight speed of males is faster.
