Schematic diagram of pre-experimental mosquitoes.
In the pre-experiment, the 13th flagellomere segment at the most distal were cut off with Venus scissors.

Antennal artificial cut for the first round blood-sucking behavior test.
A. Antennal without treatment; B~E. 3, 6, 9, and 12 segments of the antenna were cut off respectively; F~G. Venus scissors for cutting antennae.
Fig 4.
The percentage of blood-sucking of Ae. albopictus with antennal segment defection.
The horizontal axis represents the number of clipped antennal segments, and the vertical axis represents the average blood-sucking percentage. Asterisks indicate significant differences. N = 10 groups, 100 mosquitoes in total.

Antennal artificial cut for the second round blood-sucking behavior test.
A~F. 3, 6, 7, 8, 9, and 12 segments of the antenna were cut off respectively; G. The percentage of blood-sucking of Ae. albopictus with antennal segment defection. N = 10 groups, 10 mosquitoes in each group.
